AD8672ARZ Operational amplifier, 2-fold, 4 V/µs, 10 MHz, SO-8

Precision, Very Low Noise, Low Input Bias Current Operational Amplifiers

Description The AD8671/AD8672/AD8674 are very high precision amplifiers featuring very low noise, very low offset voltage and drift, low input bias current, 10 MHz bandwidth, and low power consumption. Outputs are stable with capacitive loads of over 1000 pF. Supply current is less than 3 mA per amplifier at 30 V. The AD8671/AD867 /AD8674’s combination of ultralow noise, high precision, speed, and stability is unmatched. The MSOP version of the AD8671/AD8672 requires only half the board space of comparable amplifiers. Applications for these amplifiers include 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. The AD8671/AD8672 are specified over the extended industrial temperature range (-40°C to +125°C), and the AD8674 is specified over the industrial temperature range (-40°C to +85°C). The AD8671/AD8672 are available in the 8-lead SOIC and 8-lead MSOP packages. The AD8674 is available in 14-lead SOIC and 14-lead TSSOP packages. Surface-mount devices in MSOP packages are available in tape and reel only.
