AD8671ARMZ

AD8671 is single, very high precision amplifier featuring very low noise, very low offset voltage and drift, low input bias current, 10MHz bandwidth, and low power consumption. Outputs are stable with capacitive loads of over 1000pF. Supply current is less than 3mA per amplifier at 30V. The device’s combination of ultralow noise, high precision, speed and stability is unmatched. Applications for this amplifier includes high quality PLL filters, precision filters, medical and analytical instrumentation, precision power supply controls, ATE, data acquisition, and precision controls as well as professional quality audio.
