Dual OPAmp-Dual Comparator and Adj. Shunt Regulator
The IP102/A is a monolithic IC that includes two
operational amplifiers, two comparators and an
adjustable shunt regulator. This device is offering
space and cost saving in many applications like
power supply management or data acquisition
systems.
Operational Amplifiers

- Low Supply Current : 200uA/amp
- Medium Speed : 1.5MHz
- Low Level Output Voltage Close to V
EE
: 0.1V Typ.

Comparators

- Low Supply Current : 200uA/amp(Vcc = 5V)
- Low Output Saturation Voltage 0.1V (Io = 4mA)

Adjustable Shunt Regulator

- Adjustable Output Voltage : Vref to 18V
- Sink Current Capability : 0.5 to 150mA
- 1% Voltage Precision
- Latch-up Immunity
