INA146 Overview
Description
The INA146 is a precision difference amplifier that can be used to accurately attenuate high differential voltages and reject high common-mode voltages for compatibility with common signal processing voltage levels. High-voltage capability also affords inherent input protection.
Key Features
- High common-mode voltage: – 40 V at VS = 5 V – ±100 V at VS = ±15 V
- Differential gain = 0.1 V/V TO 100 V/V: – Set with External Resistors
- Low quiescent current: 570 µA
- Wide supply range: – Single Supply: 4.5 V to 36 V – Dual Supplies: ±2.25 V to ±18 V
- Low gain error: 0.025%
- High common-mode rejection: 80 dB
