  • 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.

    Key Features

    • Sink current capability: 1 to 100mA
    • 0.4% and 1% voltage precision
    • Wide power supply range: ±1V to ±18V
    • Differential input voltage range equal to the supply voltage
    • Low supply current (1.1ma) independent of supply voltage
    • Low input offset voltage: ±1mV typ
    • Low input bias current: 25nA typ
    • Low output saturation voltage: 250mV typ (Io = 4mA)
    • Fixed Vref to 2.5V
    • Input common-mode voltage range includes ground
