Current-sense amplifier offers power consumption and accuracy benefits

Maxim Integrated Products has added to the company’sportfolio of high-side current-sense amplifiers (CSAs).

Designed for space-constrained portable applications, the 1 mm2 MAX9634 claims to set benchmarks for size, performance, and power consumption.   

Combined with its wide (1.6 V to 28 V) input-voltage range, the features make the MAX9634 well suited for a broad selection of battery-powered devices, including smartphones, digital cameras, PDAs, MP3 cameras, and notebook  computers.

The MAX9634 is optimized for compact designs that require precision monitoring. The device consumes an industry-low 1microamp of quiescent current (IQ) to conserve battery life, and it is offered in the smallest package-a tiny, 1 mm x 1 mm x 0.6 mm, 4-bump UCSP, which is 9x smaller than competing SOT23-housed devices. The device features an ultra-low ±250 microvolt (max) Vos and 0.5 percent (max) gain error. This high accuracy simplifies designs, and eliminates the need to worry about worst-case error tolerances.


The MAX9634 is fully specified over the -40 to +85 degrees Celsius extended temperature range, and is available in 4-bump UCSP and 6-pin SOT23 packages. Prices start at 0.69 US Dollars (1000-up, FOB USA).
