general description the MAX5741 quad, 10-bit, low-power, buffered volt- age-output, digital-to-analog converter (dac) is pack- aged in a space-saving 10-pin ?ax package (5mm ? 3mm). the wide supply voltage range of +2.7v to +5.5v and 229? supply current accommodates low- power and low-voltage applications. dac outputs employ on-chip precision output amplifiers that swing rail-to-rail . the MAX5741? reference input accepts a voltage range from 0 to v dd . in power-down the refer- ence input is high impedance, further reducing the sys- tem? total power consumption. the 20mhz, 3-wire spi, qspi, microwire and dsp-compatible serial interface saves board space and reduces the complexity of opto- and transformer-isolated applications. the MAX5741 on-chip power-on reset (por) circuit resets the dac outputs to zero and loads the output with a 100k ? resistor to ground. this provides additional safety for applications that drive valves or other transducers that need to be off on power-up. the MAX5741? software controlled power-down reduces supply current to less than 0.1? and provides software- selectable output loads (1k ? , 100k ? , or high impedance) while in power-down. the MAX5741 is specified over the -40? to +125? extended temperature range and avail- able in a 10-pin ?ax package applications automatic tuning gain and offset adjustment power amplifier control process control i/o boards battery-powered instruments vco control features ultra-low power consumption 229? at v dd = +3.6v 271? at v dd = +5.5v wide +2.7v to +5.5v single-supply range 10-pin ?ax package 0.3? power-down current guaranteed 10-bit monotonicity (?lsb dnl) safe power-up reset to zero volts at dac output three software-selectable power-down impedances (100k ? , 1k ? , hi-z) fast 20mhz, 3-wire spi, qspi, and microwire- compatible serial interface rail-to-rail output buffer amplifiers schmitt-triggered logic inputs for direct interfacing to optocouplers wide -40 c to +125 c operating temperature range MAX5741 10-bit, low-power, quad, voltage-output dac with serial interface ________________________________________________________________ maxim integrated products 1 1 2 3 4 5 10 9 8 7 6 outd outc outb outa gnd v dd sclk cs MAX5741 max top view ref din pin configuration 19-2123; rev 2; 7/03 for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. rail-to-rail is a registered trademark of nippon motorola, inc. spi and qspi are trademarks of motorola, inc. microwire is a trademark of national semiconductor, corp. ordering information part temp range pin-package MAX5741eub -40 c to +85 c 10 max MAX5741aub -40 c to +125 c 10 max functional diagram appears at end of data sheet. .com .com .com .com 4 .com u datasheet

MAX5741 10-bit, low-power, quad, voltage-output dac with serial interface _______________________________________________________________________________________ 9 detailed description the MAX5741 contains four 10-bit, voltage-output, low- power digital-to-analog converters (dacs). each dac employs a resistor word string architecture that con- verts a 10-bit digital input word to an equivalent analog output voltage proportional to the applied reference voltage. the MAX5741 shares one reference input (ref) between all four dacs. the MAX5741 includes rail-to-rail output buffer amplifiers for each dac, and input logic for simple microprocessor (p), and cmos interfaces. the power-supply range is from +2.7v to +5.5v ( functional diagram ). the MAX5741 s reference input accepts a voltage range from 0 to v dd . in power- down mode the reference input is high impedance. the MAX5741 is compatible with the 3-wire spi, qspi, microwire, and dsp serial interface with schmitt-trig- gered logic inputs. reference input and dac output range the reference input accepts positive dc and ac sig- nals. the voltage at ref sets the full-scale output volt- age of the four dacs. the reference input voltage range is 0 to v dd . the impedance at ref is 45k ? . the voltage at ref can vary from gnd to v dd . the output voltages (v out_ ) are represented by a digitally pro- grammable voltage source as: v out_ = (v ref ? d) / 2 10 where d is the decimal equivalent of binary dac input code ranging from 0 to 1023. v ref is the voltage at ref. output buffer amplifiers all dacs are internally buffered at the output. the buffer amplifiers have both rail-to-rail common mode and (gnd to v ref ) output voltage range. the buffers are unity-gain stable with c l = 200pf and r l = 5k ? . buffer amplifiers are disabled during power-up and individual dac outputs are shorted to gnd through a 100k ? resistor. buffer amplifiers can individually or alto- gether be powered-down by programming the input register control bits. during power down, contents of the input and dac registers remain the same. on wake-up all dac outputs are restored to their pre- power down voltage values. power-down mode in power-down mode, the dac outputs are pro- grammed to one of three output states, 1k ? , 100k ? , or floating (table 1). the ref input is high impedance (2m ? typ) to conserve current drain from the system reference; therefore, the system reference does not have to be powered-down. the dac outputs return to the values contained in the registers when brought out of power-down. the recovery time, from total power- down to power-up, is 8s. this extra time is needed to allow the internal bias to wake-up. power-down mode reduces current consumption to 0.3a. 3-wire serial interface the MAX5741 digital interface is a standard 3-wire con- nection compatible with spi/qspi/microwire/dsp interfaces. the chip-select input ( cs ) frames the serial data loading at din. immediately following cs high-to- low transition, the data is shifted synchronously and latched into the input register on the falling edge of the serial clock input (sclk). after 16 bits have been loaded into the serial input register, it transfers its con- pin description pin name function 1 cs chip-select input 2 sclk serial clock input 3v dd power-supply input 4 gnd ground 5 din serial data input 6 ref external reference voltage input 7, 8, 9, 10 outa outd dac voltage outputs. power-on reset sets dac registers to zero, and internally connects out to gnd with 100k ? resistor. .com .com .com .com .com 4 .com u datasheet
