STMicroelectronics TSX711

The TSX711, TSX711A, and TSX712 series of operational amplifiers (op amps) offer high precision functioning with low input offset voltage down to a maximum of 200 µV at 25 °C. In addition, their rail-to-rail input and output functionality allow these products 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 TSX71x is able to operate with. Thus, the TSX71x has the big advantage of offering a large span of supply voltages, ranging from 2.7 V to 16 V. They can be used in multiple applications with a unique reference. Low input bias current performance makes the TSX71x 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. High ESD tolerance (4 kV HBM) and a wide temperature range are also good reasons to use the TSX71x in the automotive market segment.
