com types · Package type: HT9281: TSOT23-5 HT9282: 8-pin DIP/SOP HT9284: 14-pin DIP/SOP Applications · Automotive · Portable Equipment · Photodiode Amplifier · Analog Filters · Notebooks and PDAs · Battery Powered Systems General Description The Holtek HT9281/HT9282/HT9284 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.
