XR-4202
XR-4202 is Programmable Quad Operational Amplifier manufactured by Exar.
DESCRIPTION
FUNCTIONAL BLOCK DIAGRAM
The XR-4202 is an array of four independent operational amplifiers on a single silicon chip. The operating current of the array is externally controlled by a single resistor or current source, allowing the user to trade-off power dissipation for bandwidth.
