Description
The TSC1021 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage.
   
Features
• Wide common-mode operating range
    independent of supply: 2.8 V to 30 V
• Wide common-mode survival range: -32 V to
    60 V (reversed battery and load-dump
    conditions)
• Maximum input offset voltage:
    - ±1.5 mV for Tamb = 25 °C
    - ±2.3 mV for -40 °C < Tamb < 125 °C
• Maximum total output voltage error:
    - ±1.5 % for Tamb = 25 °C
    - ±2.5 % for -40 °C < Tamb < 125 °C
• Maximum variation over temperature:
    - dVos/dT = 8 µV/°C
    - dVout/dT = 100 ppm/°C
• Low current consumption: ICC max = 300 µA
• -40 °C to 125 °C operating temperature
    range
• Internally fixed gain: 20 V/V, 50 V/V
• EMI filtering
   
Applications
