Description
The TSX7192 dual, 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 TSX7192 is
able to operate with.
Thus, the TSX7192 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
TSX7192 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 TSX7192 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 TSX7192 in the automotive market
segment.
