AD8674ARZ

精密放大器 Prec Low Noise Low Input Bias Crnt Quad

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

GENERAL DESCRIPTION AD8674ARZ

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/AD8672/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.
