TSM109/A

Dual Comparator and Voltage Reference

COMPARATOR

s Low supply current (1.1ma) independent of

supply voltage

s Low input bias current: 25nA typ

s Low input offset voltage: ±1mV typ

s Input common-mode voltage range

includes ground

s Low output saturation voltage: 250mV typ

(Io = 4mA)

s Differential input voltage range equal to the

supply voltage

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