product preview information concerns products in the formative or design phase of development. characteristic data and other specifications are design goals. texas instruments reserves the right to change or discontinue these products without notice. dual wideband, current feedback operational amplifier with disable description the opa2691 sets a new level of performance for broadband dual current feedback op amps. operating on a very low 5.1ma/ch supply current, the opa2691 offers a slew rate and output power normally associated with a much higher supply current. a new output stage architecture delivers a high output current with minimal voltage headroom and crossover distortion. this gives exceptional single- supply operation. using a single +5v supply, the opa2691 can deliver a 1v to 4v output swing with over 120ma drive current and 150mhz bandwidth. this combination of features makes the opa2691 an ideal rgb line driver or single supply analog-to-digital converter (adc) input driver. features l flexible supply range: +5v to +12v l wideband +5v operation: 230mhz (g = +2) l unity gain stable: 400mhz (g = 1) l high output current: 190ma l output voltage swing: 4.0v l high slew rate: 2100v/ m s l low supply current: 5.1ma/ch l low disabled current: 100 m a/ch applications l xdsl line driver / receiver l matched i/q channel amplifier l broadband video buffers l high speed imaging channels l portable instruments l differential adc drivers l active filters l wideband inverting summing the opa2691s low 5.1ma/ch supply current is precisely trimmed at 25 c. this trim, along with low drift over temperature, ensures lower maximum supply current than competing products. system power may be further reduced by using the optional disable control pin (so-14 only). leaving this disable pin open, or holding it high, gives normal operation. if pulled low, the opa2691 supply current drops to less than 150 m a/ch while the output goes into a high impedance state. this feature may be used for power savings. single supply adsl upstream driver 100 w 2k w 2k w 1 f 12.4 w 100 w 2vp-p 324 w 324 w 1/2 opa2691 1/2 opa2691 +12v 1:2 15vp-p 12.4 w +6.5v opa2691 related products singles duals triples voltage feedback opa690 opa2690 opa3690 current feedback opa691 opa2681 opa3691 fixed gain opa692 opa2682 opa3692 opa2681 opa2681 opa2691 sbos224 C december 2001 www.ti.com copyright ? 2001, texas instruments incorporated please be aware that an important notice concerning availability, standard warranty, and use in critical applications of texas instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
