Description
The O2140G-12 is an electronic component in the product category of IC Chips. It is part of the TSC1021 series and is designed to measure a small differential voltage on a high-side shunt resistor and translate it into a ground-referenced output voltage. It features a wide common-mode operating range of 2.8 to 30 V, independent of the power supply. It also has a wide common-mode surviving range of -32 to 60 V, making it suitable for reversed battery and load-dump conditions. The maximum input offset voltage is ±1.5 mV for Tamb = 25°C and ±2.3 mV for -40°C < Tamb < 125°C. The maximum total output voltage error is ±1.5% for Tamb = 25°C and ±2.5% for -40°C < Tamb < 125°C. It has low current consumption with a maximum of 300 µA and operates in a temperature range of -40 to 125°C. The O2140G-12 has an internally fixed gain of 20 V/V or 50 V/V and also features EMI filtering.
