General Description
The Holtek HT9291/HT9292/HT9294 range of Low
Power Operation Amplifiers offer the advantage of a sin-
gle supply voltage down to as low as 1.4V as well as the
advantages of an extremely low quiescent current of
only 0.6mA/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 sta-
ble. The devices are available in a range of packages
according the number of internal amplifiers. The special
characteristics of these devices will ensure their excel-
lent use in applications with stringent low power de-
mands such as portable products, battery powered
equipment, low power sensor signal processing etc.
