TPA2296(3PEAK)

The TPA2296 family is high-voltage, high-side current sense amplifier with voltage output. The TPA2296 can sense drops across shunts at common-mode voltages from −0.1 V up to 70 V. The TPA2296 is available with three output voltage scales: 20 V/V, 50 V/V, and 100 V/V, with up to 0.5-MHz bandwidth.

The TPA2296 operates from a single 3.0-V to 18-V supply and 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 0.6μV/°C throughout the operating temperature range and the common-mode voltage range.

The TPA2296 is offered in 6-pin and 5-pin SOT23 packages.
