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
