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 220μA/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.
