CONTROLLER
DESCRIPTION
SOP-8
LINEAR INTEGRATED CIRCUIT
The UTC
UM609A
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 switching battery chargers.
FEATURES
OPERATIONAL AMPLIFIER
* Low supply current: 75uA/Per OP AMP.(@ V
CC
=5V)
* Medium bandwidth(unity gain): 1MHz
* Large output voltage swing: 0V ~ (V
CC
-1.5V)
* Wide power supply range: 3V~36V
VOLTAGE REFERENCE
* Fixed output voltage reference 2.5V
* Reference voltage tolerance
UM609A-1: ±0.4%
UM609A-2: ±1%
* Sink current capability: 0.05~80mA
* Typical output impedance: 0.2Ω
