描述 Description

The TPA2295C family is of high voltage, high side current sense amplifier with voltage output, internal comparator, and 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.

The TPA2295C features one open drain comparator with internal 0.6V references. Comparator works with a latching capability.

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.
