• Low Supply Current … 20 µ A Typ

• Single Power Supply

• Rail-to-Rail Common-Mode Input Voltage

Range

• Push-Pull Output Circuit

• Low Input-Bias Current

• Battery Packs for Sensing Battery Voltage

• MP3 Players, Digital Cameras, PMPs

• Cellular Phones, PDAs, Notebook Computers

• Test Equipment

• General-Purpose Low-Voltage Applications

The TLV7256 is a CMOS-type general-purpose dual comparator capable of single power-supply operation and

using lower supply currents than the conventional bipolar comparators. Its push-pull output can connect directly

to local ICs such as TTL and CMOS circuits.
