Description

The TPA1295 family is of high voltage, Bi-directional

current sense amplifier with voltage output. The TPA1295 can

sense drops across shunts at common-mode voltages from –

0.3V to 70 V. The TPA1295 are available with three output

voltage scales: 20V/V, 50V/V, 100V/V, with up to 500KHz

bandwidth.

The TPA1295 operates from single 3V to 18V supply, offers

breakthrough performance throughout the ?40°C to +125°C

temperature range. It features a zero-drift core, which leads to

a typical offset drift of 0.4μV/°C throughout the operating

temperature range and the common-mode voltage range.

The TPA1295 family is offered in 8-pin SOP package.
