TPA2295C中文资料HV, High side Current Sense Amplifier with Internal Comparator数据手册3PEAK规格书

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.
