The Holtek HT9291/HT9292/HT9294 range of Low Power Operation Amplifiers offer the advantage of a single supply voltage down to as low as 1.4V as well as the advantages of an extremely low quiescent current of only 0.6uA/amplifier. One other major advantage of these devices lie in their rail-to-rail voltage operation for maximum range. The devices also provide a typical gain bandwidth product of 11kHz and are also unity gain stable.
