Applications

General Description

The Holtek HT9231/HT9232/HT9234 range of

Operational Amplifiers operate with a single supply

voltage as low as 2.0V and offer a low supply current of

only 220

mA/amplifier. In offering rail-to-rail output

voltage the devices can operate with a maximum

voltage range. The devices also provide a gain

bandwidth product of 2.3MHz and are also unity gain

stable. These products are suitable for a wide range of

analog signal processing applications but especially

suitable for the portable device and battery powered

equipment application areas.
