GENERAL DESCRIPTION
The AD4004 is a JFET input operational amplifier featuring
precision, very low bias current, and low power in a tiny
package at a very attractive price. Combining high input
impedance, low input bias current, wide bandwidth, and fast
slew rate, the AD4000 is an ideal amplifier for driving A/D
inputs and buffering D/A converter outputs.
Additional applications for the AD4004 include electronic
instruments; ATE amplification, buffering, and integrator
circuits;
Instrumentation quality photodiode amplification; fast
precision filters (including PLL filters), utility functions like
reference buffering, level shifting, control I/O interface, power
supply control and monitoring functions.
