Description The TSX7191， TSX7191A single， operational amplifier （op amp） offers high precision functioning with low input offset voltage down to a maximum of 200 μV at 25 °C. In addition， its railto-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. Thus， the TSX7191， TSX7191A has the great advantage of offering a large span of supply voltages， ranging from 2.7 V to 16 V. It can be used in multiple applications with a unique reference. Low input bias current performance makes the TSX7191， TSX7191A perfect when used for signal conditioning in sensor interface applications. In addition， low-side and high-side current measurements can be easily made thanks to rail-to-rail functionality. The TSX7191， TSX7191A is a decompensated amplifier and must be used with a gain greater than 10 to ensure stability. High ESD tolerance （4 kV HBM） and a wide temperature range are also good arguments to use the TSX7191， TSX7191A in the automotive market segment.
