AM447 Overview
The AM447 is a high precision amplifier, designed for amplification of sensor bridge signals up to 35mV full scale. The single supply circuit consists of a high precision instrumentation amplifier (IA) and an integrated ratiometric output stage. Input offset voltages less than ±25µV (±1µV/°C) are adjustable by only two externally trimmable resistors.
AM447 Key Features
- Very Low Offset Voltage: < 25µV Low Input Bias Current: ≤ 5nA High Input Sensitivity High CMRR: > 90dB min Wide Operatin
AM447 Applications
- Small Signal (Bridge) Amplifier Low Pressure Sensors Automotive Applications DMS Interface Interface for Ceramic Sensors
