ADA4177-2: OVP AND EMI PROTECTED, PRECISION, LOW NOISE AND BIAS CURRENT OP AMP

The ADA4177-2 is a dual-channel amplifier featuring low offset voltage (2 μV typical) and drift (1 μV/°C maximum), and low input bias current, noise, and current consumption (500 μA typical). Outputs are stable with capacitive loads of more than 1000 pF with no external compensation.

The ADA4177-2 inputs set a new standard in precision amplifier robustness providing input protection against signal excursions 32 V beyond either supply, as well as 70 dB of rejection for electromagnetic interference (EMI) at 1000 MHz.

Applications for this amplifier include sensor signal conditioning (such as thermocouples, RTDs, and strain gages), process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems. The ADA4177-2 is useful in line powered and portable instrumentation, precision filters, and voltage or current measurement and level setting.

The ADA4177-2 operates over the −40°C to +125°C industrial temperature range. The ADA4177-2 is available in an 8-lead SOIC package and an 8-lead MSOP package.
