TPA1295

HV, Bi-directional Current Sense Amplifier

Features

Description

◼

SMALL VOLTAGE OFFSET:

TPA1295: ±100uV (MAX)

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.

◆

◼

WIDE COMMON MODE VOLTAGE: -0.3V to +70V

WIDE CMRR THROUGH COMMON VOLTAGE: 130dB

SUPPLY VOLTAGE: 3V to +18V

ACCURACY and ZERO-DRIFT PERFORMANCE

◆

±0.5% Gain Error (Max, -40°C ~125°C)

0.5μV/°C Offset Drift (Max, -40°C ~125°C)

5ppm/°C Gain Drift (Max, -40°C ~125°C)

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.

◼

THREE GAIN OPTIONS for VOLTAGE OUTPUT

◆

TPA1295T: 20V/V

TPA1295F: 50V/V

TPA1295H: 100V/V

Applications

◼
