ADA4077-2:  4 MHz, 7 nV/√Hz, Low Offset and Drift, High Precision Amplifier

Product Details

Product Status:Recommended for New Designs

The ADA4077-2 is a dual amplifier featuring extremely low offset voltage and drift and low input bias current, noise, and power consumption. Outputs are stable with capacitive loads of more than 1000 pF with no external compensation.

Applications for this amplifier include sensor signal conditioning (such as thermocouples, RTDs, strain gauges), process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems. The ADA4077-2 is useful in line powered and portable instrumentation, precision filters, and voltage or current measurement and level setting.

Unlike the amplifiers of some competitors, the ADA4077-2 is specified over the extended industrial temperature range for operation from −40°C to +125°C with MSL1 rating for the most demanding operating environments. It is available in 8-lead SOIC (including the B-Grade) and MSOP (A-Grade only) packages.
