General Description

The HT9274 is a CMOS quad micro-power op-

erational amplifier featuring high input imped-

ance, extremely low power, high gain and high

stability.

gain, low frequency, low power applications, es-

pecially ideal for battery powered systems

where mA range of standby current is essential

for long battery life span. For example, in

multi-standard Caller ID systems, HT9274 is

ideal as a low power line signal monitor/detec-

tor, and in car alarm systems, the HT9274 is ex-

cellent for piezo vibratile detector signal

amplifier application.

It allows common mode input voltage range

which extends below the negative rail, output

swings to both rails with a reasonable sink and

souce capability of the output drive current.

This cost-effective device is suitable for high
