AD8624ARUZ

AD8624 is a quad-precision rail-to-rail output operational amplifier with low supply currents of only 350μA/amplifier maximum over temperature and supply voltages. This also has an input bias current cancellation circuitry that provides a very low input bias current over the full operating temperature. This is perfectly suited for applications where large error sources cannot be tolerated. Many systems can take advantage of the low noise, dc precision, and rail-to-rail output swing provided by this maximizing the signal-to-noise ratio and dynamic range for low-power operation. Application includes portable precision instrumentation laser diode control loops, strain gauge amplifiers, medical instrumentation, and thermocouple amplifiers.
