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 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.
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.主要特性
