General Description
The HT92232/HT92252 family of general purpose
operational amplifiers offer the benefits of wide
bandwidth along with low quiescent current. Both
devices operate with a supply voltage down to 2.1V,
and deliver full rail to rail input and output voltage
range operation. Both have a -40°C to 85°C operating
temperature range but differ in their bandwidth and
quiescent current characteristics. The HT92232 device
provides a 300kHz bandwidth with a 16μA (typ.)
per amplifier quiescent current while the HT92252
provides 1MHz bandwidth with a 40μA (typ.) per
amplifier quiescent current.
With their single supply operation and low power
consumption features coupled with their low cost these
operational amplifiers are suitable for use in a wide
range of applications. With regard to packaging, both
devices are supplied in 8-pin SOP/MSOP package
formats.
