AD8668

FEATURES Offset voltage: 2.5 mV max Low input bias current: 1 pA max Single-supply operation: 5 V to 16 V Dual-supply operation: ±2.5 V to ±8 V Low noise: 8 nV/√Hz @ 10 kHz Wide bandwidth: 4 MHz Rail-to-rail output Unity-gain stable Lead-free packaging AD8666/AD8668 qualified for automotive applications APPLICATIONS Sensor amplification Reference buffers Medical equipment Physiological measurements Signal filters and conditioning Consumer audio Photodiode amplification ADC driver Level shifting circuits GENERAL DESCRIPTION The AD866x family is single supply, rail-to-rail output amplifiers with low noise performance featuring an extended operating range with supply voltages up to 16 V. They also feature low input bias currents, wide signal bandwidth, and low input voltage and current noise. For lower offset voltage, choose the AD8661/AD8662/AD8664 family. The combination of low offsets, very low input bias currents, and wide supply range make these amplifiers useful in a wide variet...
