HM8521, HM8522, HM8524

3.4μA, 90kHz, RRIO CMOS Operational Amplifiers

General Description

The HM8521 (single), HM8522 (dual) and HM8524 (quad) are ultra-low power

operational amplifiers that provide 90kHz bandwidth with only 3.4μA quiescent current.

These rail-to-rail input and output amplifiers are specifically designed for battery-powered

applications. The input common-mode voltage range extends 300mV beyond the power-

supply rails and the output swings to only 6mV of the rails, maintaining wide dynamic

range. Unlike some micro-power op-amps, these parts are unity-gain stable. The

HM852x family features a low input bias current that allows the use of large source and

feedback resistors.

The HM852x op-amps are 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 HM8521 is available in 5-lead SC70 and SOT-23 packages. The HM8522

is available in 8-lead MSOP and SOIC packages. The HM8524 is available in 14-lead

TSSOP and SOIC packages.
