MAX9634 Datasheet Precision Current-sense Amplifier

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: Click here for production status of specific part numbers. MAX9634.

General Description

The MAX9634 high-side current-sense amplifier offers precision accuracy specifications of VOS less than 250μV (max) and gain error less than 0.5% (max).

Quiescent supply current is an ultra-low 1μA.

The MAX9634 fits in a tiny, 1mm x 1mm UCSP™ package size or a 5-pin SOT23 package, making the part ideal for applications in notebook computers, cell phones, PDAs, and all batteryoperated portable devices where accuracy, low quiescent current, and small size are critical.

Key Features

  • an input common-mode voltage range from 1.6V to 28V. These current-sense amplifiers have a voltage output and are offered in four gain versions: 25V/V (MAX9634T), 50V/V (MAX9634F), 100V/V (MAX9634H), and 200V/V (MAX9634W). The four gain selections offer flexibility in the choice of the external current-sense resistor. The very low 250μV (max) input offset voltage allows small 25mV to 50mV full-scale VSENSE voltage for very low voltage drop at full-current measurement. The MAX9634 is offered in t.
