AD8659ARZ-R7

AD8659 is a quad micropower, precision, rail-to-rail input/output amplifiers optimized for low power and wide operating supply voltage range applications. 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 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. It is suitable for use in portable operating systems, current monitors, 4mA to 20mA loop drivers, buffer/level shifting, multipole filters, remote/wireless sensors and low power transimpedance amplifiers.
