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. 40 30 20 0 –50 –25 0 25 50 TEMPERATURE (°C) 75 100 125 08804-023 10 Figure 3. AD8657, Supply Current vs. Temperature Table 1. Precision Micropower Op Amps (> RSENSE, the current through the load resistor at the receiver side is almost equivalent to ISENSE. Figure 78 is designed for a full-scale input voltage of 5 V. At 0 V of input, loop current is 3.5 mA; and at a full scale of 5 V, the loop current is 21 mA. This allows software calibration to fine tune the current loop to the 4 mA to 20 mA range. The AD8657 and ADR3550 both consume only 160 μA quiescent current, making 3.34 mA current available to power additional signal conditioning circuitry or to power a bridge circuit.
