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