Introduction

The ADA4077-2ARMZ is a basket of dual-channel operational amplifiers, featuring extremely low offset voltage and drift, as well as low input bias current, noise and power consumption. When using capacitive loads of 1000 pF or more, the output is stable and no external compensation is required.

The applications of the ADA4077-2ARMZ amplifier include sensor signal conditioning (such as thermocouples, resistance temperature detectors (RTDS), strain gauges), process control front-end amplifiers, and precise diode power measurement in optical and wireless transmission systems. The ADA4077-2ARMZ is also suitable for portable instruments and meters powered by lines, precision filters, and voltage or current measurement and level setting.

Unlike other amplifiers, the ADA4077-2ARMZ features MSL1 rated performance, complies with strict assembly process standards, and has a rated temperature range of -40 °C to +125°C, extending the industrial temperature range and making it suitable for demanding working environments.
