Original Press Release:
1mm² Current-Sense Amplifier Sets Benchmarks for Power Consumption and Accuracy
High-side CSA features ±250µV VOS and 0.5% gain error.
The MAX9634 uniquely combines an industry-low 1µA IQ with ±250µV VOS and 0.5% gain error for battery-operated devices that require precision monitoring.
SUNNYVALE, CA - Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX9634, the latest addition to its industry-leading portfolio of high-side current-sense amplifiers (CSAs). Designed for space-constrained portable applications, the 1mm² MAX9634 sets benchmarks for size, performance, and power consumption. Combined with its wide (1.6V to 28V) input-voltage range, these superior 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. This device consumes an industry-low 1µA of quiescent current (IQ) to conserve battery life, and it is offered in the smallest package-a tiny, 1mm x 1mm x 0.6mm, 4-bump UCSP(TM), which is 9x smaller than competing SOT23-housed devices. The small size of the MAX9634 is even more impressive when viewed in conjunction with its superior performance. The device features an ultra-low ±250µV (max) VOS and 0.5% (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°C to +85°C extended temperature range, and is available in 4-bump UCSP and 6-pin SOT23 packages. Prices start at $0.69 (1000-up, FOB USA).
