Description
The TSX9291 and TSX9292 operational
amplifiers (op-amps) offer excellent AC
characteristics such as 16 MHz gain bandwidth,
27 V/μs slew rate, and 0.0003 % THD+N. They
are decompensated amplifiers which are stable
when used with a gain higher than 2 or lower than
-1. The rail-to-rail input and output capability of
these devices operates on a wide supply voltage
range of 4 V to 16 V. These last two features
make the TSX929x series particularly well-
adapted for a wide range of applications such as
communications, I/V amplifiers for ADCs, and
active filtering applications.
