DUAL OPERATIONAL AMPLIFIER

AND CURRENT CONTROLLER

DESCRIPTION

The FA103/A is a monolithic IC that includes one independent OP-AMP

and another OP-AMP for witch the non inverting input is wired to a 2.5V

fixed voltage reference.

This device is offering space and cost saving in many applications like

power supply management or data acquisition systems

FEATURES

OPERATIONAL AMPLIFIER

* Low input offset voltage: 0.5mV typ. for FA103A

* Low supply current: 350uA/op.(@ Vcc=5V)

* Medium bandwidth(unity gain): 0.9MHz

* Large output voltage swing: 0 V ~ (Vcc-1.5V)

* Input common mode voltage range includes ground

* Wide power supply range: 3V ~ 32V , ±1.5 ~ ±16V

VOLTAGE REFERENCE

* Fixed output voltage reference 2.5V

* ±0.4% and ±1% voltage precision

* Sink current capability : 1 ~ 100mA

* Typical output impedance : 0.2
