AD8628ARZ Zero-Drift, Single-Supply, Rail-to-Rail Input/Output Operational Amplifier IC

AD8628ARZ Zero-Drift, Single-Supply, Rail-to-Rail Input/Output Operational Amplifier IC

The AD8628ARZ Zero-Drift amplifier has ultralow offset, drift, and bias current. The AD8628 are wide bandwidth auto-zero amplifiers featuring rail-to-rail input and output swing and low noise. Operation is fully specified from 2.7 V to 5 V single supply (±1.35 V to ±2.5 V dual supply). The AD8628 provide benefits previously found only in expensive auto-zeroing or chopper-stabilized amplifiers. Using Analog Devices, Inc., topology, these zero drift amplifiers combine low cost with high accuracy and low noise. No external capacitor is required. In addition, the AD8628 greatly reduce the digital switching noise found in most chopper-stabilized amplifiers.
