AD8691AUJZ 精密放大器

AD8691AUJZ

精密放大器 Low Noise SGL CMOS RRO

GENERAL DESCRIPTION AD8691AUJZ

The AD8691, AD8692, and AD8694 are low cost, single, dual,

and quad rail-to-rail output, single-supply amplifiers featuring

low offset and input voltages, low current noise, and wide signal

bandwidth. The combination of low offset, low noise, very low

input bias currents, and high speed make these amplifiers useful

in a wide variety of applications. Filters, integrators, photodiode

amplifiers, and high impedance sensors all benefit from this

combination of performance features. Audio and other ac

applications benefit from the wide bandwidth and low

distortion of these devices.
