High Precision Double Integration Type A/D Converter
REJ03D0862-0201 Rev.2.01 Dec 27, 2007
Description
M62303FP is a double integration type A/D converter support system, and is a semiconductor integrated circuit which can work as A/D converter of 14 bits or more by being used with MCU and by inputting SI, SCK1, CS, and CONTIN. High precision A/D translation system can be realized without using high precision external parts by proofreading A/D acquired values with two or more known conversion values such as reference voltage, grounding (zero) voltage and so forth.
Features
* * * * * High precision (14 bits or more) double integration type A/D converter Positive/negative constant voltage source built-in (+6.3 V, -6.0 V Typ) Positive/negative constant current source built-in (Isource = 2 mA, Isink = 0.2 mA Max) Independent 2ch operational amplifier built-in System reset built-in (4.5 V Typ)
Application
High precision control systems, such as temperature control and speed control

Pin Description
Pin No. 56 55 54 Pin Name SI SCK1 CS Function Serial data input terminal. Serial data of 15 bits data length is input. Shift clock input terminal. Signal from SI terminal is input into 15-bit shift register at the rise of a clock. "L" level of this terminal enables shift clock, and "H" level makes shift register contents stored into multiplexer control register (analog switches) and unenables clock input. A pulse is input. Double integration type A/D converter is started synchronizing with this pulse. Moreover, the optimal full scale can be set up by setting up with C and R so that it may be set to TCONT 2.14 CR. Digital part power supply terminal Digital part GND terminal. This terminal is externally connected to analog ground terminal when IC is operative. Output terminal of reset circuit supervising the fall of a digital part power supply. Reset output rise is delayed by adding capacitor. Input side terminal of multiplexer (analog switch group) MUX.

Given the applied voltage into 41 pin is VX in the diagram above,
VX = TGND - TX TGND - TR * VR T = Pulse width
TGND, TR, and TX can be respectively expressed with nGND/f, nR/f, and nX/f, (f is clock frequency; nGND, nR, nX is count values for clock frequency f.) If these are substituted for an upper formula,
VX = nGND - nX nGND - nR * VR
VX can be expressed in this way for the number of counters.
