TSX7191, TSX7191A Low-power, precision, rail-to-rail, 9.0 MHz, 16 V operational amplifier Datasheet - production data Description The TSX7191, TSX7191A single, operational amplifier (op amp) offers high precision functioning with low input offset voltage down to a maximum of 200 V at 25 C. In addition, its rail- to-rail input and output functionality allows this product to be used on full range input and output without limitation. This is particularly useful for a low-voltage supply such as 2.7 V that the TSX7191, TSX7191A is able to operate with. Features Thus, the TSX7191, TSX7191A has the great Low input offset voltage: 200 V max. advantage of offering a large span of supply Rail-to-rail input and output voltages, ranging from 2.7 V to 16 V. It can be used in multiple applications with a unique Low current consumption: 850 A max. reference. Gain bandwidth product: 9 MHz Low supply voltage: 2.7 - 16 V Low input bias current performance makes the Stable when used with Gain 10 TSX7191, TSX7191A perfect when used for Low input bias current: 50 pA max. signal conditioning in sensor interface High ESD tolerance: 4 kV HBM applications. In addition, low-side and high-side Extended temp. range: -40 C to +125 C current measurements can be easily made Automotive qualification thanks to rail-to-rail functionality. The TSX7191, TSX7191A is a decompensated amplifier and must be used with a gain greater than 10 to Related products ensure stability. See the TSX711 for lower speeds with High ESD tolerance (4 kV HBM) and a wide similar precision temperature range are also good arguments to See the TSX561 for low-power features use the TSX7191, TSX7191A in the automotive See the TSX631 for micro-power features market segment.
