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 220mA/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.
