AD8668ARZ

精密放大器 16V 4MHz RRO Quad 16 V, 4 MHz RR0 Amplifiers

GENERAL DESCRIPTION  AD8668ARZ

The AD866x family is single supply, rail-to-rail output  amplifiers with low noise performance featuring an extended  operating range with supply voltages up to 16 V. They also  feature low input bias currents, wide signal bandwidth, and low  input voltage and current noise. For lower offset voltage, choose  the AD8661/AD8662/AD8664 family.

The combination of low offsets, very low input bias currents,

and wide supply range make these amplifiers useful in a wide

variety of cost sensitive applications normally associated with

much higher priced JFET amplifiers. Systems using high

impedance sensors, such as photo diodes, benefit from the

combination of low input bias current, low noise, and low offset

and bandwidth. The wide operating voltage range matches high

performance ADCs and DACs. Audio applications and medical

monitoring equipment can take advantage of the high input

impedance, low voltage and current noise, wide bandwidth, and

the lack of popcorn noise found in many other low input bias

current amplifiers.
