AD8624ACPZ-R7

AD8624 is a quad precision rail-to-rail output operational amplifier with low supply currents of only 215μA/amplifier maximum over temperature and supply voltages. It also has an input bias current cancellation circuitry that provides a very low input bias current over the full operating temperature. With a typical offset voltage of only 10μV, offset drift of 0.5μV/°C, and noise of only 0.2μV p-p (0.1Hz to 10Hz), are 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 the device to maximize the signal-to-noise ratio and dynamic range for low power operation. It is used in applications such as portable precision instrumentation, laser diode control loops, strain gauge amplifiers, medical instrumentation, thermocouple amplifiers.
