General Description

The H

M721 (single), HM722 (dual) and HM724 (quad) are low noise, Low voltage and

high slew rate operational amplifiers with an excellent bandwidth of 12MHz, a slew rate of

11V/μs, and a quiescent current of 820μA per amplifier at 5V, the H

M72x family can be

designed into a wide range of applications.

The H

M72x op-amps are designed to provide optimal performance in low voltage and

low noise systems The input common-mode voltage range includes ground, andthe

maximum input offset voltage are 4.0mV. These parts provide rail-to-rail output swing into

heavy loads. The H

M72x family is specified for single or dual power supplies of +2.3V to

+5.5V. All models are specified over the extended industrial temperature range of −40

℃

to +125

℃.

The H

M721 is available in 5-lead SC70 and SOT-23 packages. The HM722 is available

in 8-lead MSOP and SOIC packages. The H

M724 is available in 14-lead TSSOP and

SOIC packages.
