描述 Description

The HTC8521 (single), HTC8522 (dual) and HTC8524 (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 HTC852x family features a low input bias current that allows the use of large source and feedback resistors.The HTC852x 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 HTC8521 is available in 5-lead SC70 and SOT-23 packages. The HTC8522 is available in 8-lead MSOP and SOIC packages. The HTC8524 is available in 14-lead TSSOP and SOIC packages.
