Analog Devices / Maxim Integrated MAX44285 High-Side Current-Sense Amplifiers

Analog Devices Inc. MAX44285 Dual-Channel High-Side Current-Sense Amplifiers offer an input common-mode voltage range of 2.7V to 76V with 80kHz of small-signal bandwidth, making them ideal for interfacing with a SAR ADC for multichannel multiplexed data acquisition systems. These high-precision amplifiers have accuracy specifications of VOS less than 12μV (max.) and gain error less than 0.1% (max). By operating over the -40°C to +125°C temperature range, the MAX44285 amplifiers are especially well-suited for base stations and communication equipment, power management systems, server backplanes, and industrial control & automation. The Maxim MAX44285 amplifiers are available in 8-bump WLP and 8-pin μMAXM® packages.
