H393P

HSMC Product Specification

H393P

LOW POWER LOW OFFSET VOLTAGE COMPARATORS

Description

The H393P series consists of two independent precision voltage

comparators designed specifically to operate from a single power supply

over a wide range of voltages, the input common mode voltage range

includes ground. Owing to adoption of clamp circuitry in input pins, mis-

operation is prevented by negative input.

Features

• Wide power supply voltage range

Single power supply .............................................................................................................. 2 V to 30 V

Dual power supplies........................................................................................................

± 1 V to ± 15 V

• Wide input common-mode voltage range .................................................................... 0 V to (Vcc-1.5) V

• Low input bias current ............................................................................................................. 25 nA typ.

• High sink current capability because of open collector otput 40mA min.
