TPA2295C

HV, High side Current Sense Amplifier with Internal Comparator

Features

Description

◼

SMALL VOLTAGE OFFSET:

TPA2295C: ±0.5mV (MAX)

The TPA2295C family is of high voltage, high side current

◆

sense amplifier with voltage output, internal comparator, and

◼

WIDE COMMON MODE VOLTAGE: -0.1V to +70V

WIDE CMRR THROUGH COMMON VOLTAGE: 130dB

SUPPLY VOLTAGE: 3.0V to +18V

voltage reference. The TPA2295C can sense drops across

shunts at common-mode voltages from –0.1V to 70 V. The

TPA2295C are available with five output voltage scales:

20V/V, 50V/V, 60V/V, 100V/V, 200V/V, with up to 0.5MHz

bandwidth.

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 TPA2295C features one open drain comparator with

internal 0.6V references. Comparator works with a latching

capability.

◼

FIVE GAIN OPTIONS for VOLTAGE OUTPUT

◆

TPA2295CT: 20V/V

TPA2295CF: 50V/V

TPA2295CS: 60V/V

TPA2295CH: 100V/V

TPA2295CW: 200V/V

The TPA2295C operates from single 3.0V to 18V supply,

offers breakthrough performance throughout the −40°C to

+125°C temperature range. It features a zero drift core, which

leads to an offset drift of 0.5μV/°C throughout the operating

temperature range and the common-mode voltage range.

The TPA2295C is offered in 8-pin MSOP package.
