DESCRIPTION

The TSM109 is a monolithic IC that includes two comparators and a shunt voltage reference. This device offers space and cost savings in many applications including power supply management or data acquisition systems.

COMPARATOR

■ Low supply current (1.1ma) independent of supply voltage

■ Low input bias current: 25nA typ

■ Low input offset voltage: ±1mV typ

■ Input common-mode voltage range includes ground

■ Low output saturation voltage: 250mV typ (Io = 4mA)

■ Differential input voltage range equal to the supply voltage

■ Wide power supply range: ±1V to ±18V

VOLTAGE REFERENCE

■ Fixed Vref to 2.5V

■ 0.4% and 1% voltage precision

■ Sink current capability: 1 to 100mA
