Mar. 2004 Rev0 - 1 - WWW.INTERPIONSEMI.COM 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 VEE : 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
