Applications

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 0.6

mA/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.
