Overview
Data Sheet FEATURES Micropower at high voltage (18 V): 22 μA maximum Low offset voltage: 350 μV maximum Low input bias current: 20 pA maximum Gain bandwidth product: 230 kHz at AV = 100 typical Unity-gain crossover: 230 kHz −3 dB closed-loop bandwidth: 305 kHz Single-supply operation: 2.
7 V to 18 V Dual-supply operation: ±1.
35 V to ±9 V Unity-gain stable Excellent electromagnetic interference immunity APPLICATIONS Portable operating systems Current monitors 4 mA to 20 mA loop drivers Buffer/level shifting Multipole filters Remote/wireless sensors Low power transimpedance amplifiers GENERAL DESCRIPTION The AD8657/AD8659 are dual and quad micropower, precision, rail-to-rail input/output amplifiers optimized for low power and wide operating supply voltage range applications.
The AD8657/AD8659 operate from 2.
7 V to 18 V with a typical quiescent supply current of 18 μA.
The devices use the Analog Devices, Inc.
, patented DigiTrim® trimming technique, which achieves low offset voltage.
The AD8657/AD8659 also have high immunity to electromagnetic interference.
The combination of low supply current, low offset voltage, very low input bias current, wide supply range, and rail-to-rail input and output make the AD8657/AD8659 ideal for current monitoring in process and motor control applications.
The combination of precision specifications makes these devices ideal for dc gain and buffering of sensor front ends or high impedance input sources in wireless or remote sensors or transmitters.
The AD8657/AD8659 are specified over the extended industrial temperature range (−40°C to +125°C).
The AD8657 is available in an 8-lead MSOP package and an 8-lead LFCSP package; the AD8659 is available in a 14-lead SOIC package and 16-lead LFCSP package.
