Hot-selling and scarce AD8630ARZ Rail-to-Rail Input/Output Operational Amplifier SOP14 spot stock

Product Descriptions

This amplifier has ultralow offset, drift, and bias current . TheAD8628/AD8629/AD8630 are wide bandwidth auto-zeroamplifiers featuring rail-to-rail input and output swings and lownoise. Operation is fully specified from 2.7 V to 5 V singlesupply (±1.35 V to ±2.5 V dual supply).

​

The AD8628/AD8629/AD8630 provide benefits previouslyfound only in expensive auto-zeroing or chopper-stabilizedamplifiers. Using Analog Devices’ topology, these zero-driftamplifiers combine low cost with high accuracy and low noise .No external capacitor is required . In addition, the AD8628/AD8629/AD8630 greatly reduce the digital switching noisefound in most chopper-stabilized amplifiers .

With an offset voltage of only 1 μV, drift of less than 0.005 μV/°C, and noise of only 0.5 μV p-p (0 Hz to 10 Hz), theAD8628/AD8629/AD8630 are suited for applications in whicherror sources cannot be tolerated. Position and pressure sensors,medical equipment, and strain gage amplifiers benefit greatlyfrom nearly zero drift over their operating temperature range .Many systems can take advantage of the rail-to-rail input andoutput swings provided by the AD8628/AD8629/AD8630 toreduce input biasing complexity and maximize SNR 

.

The AD8628/AD8629/AD8630 are specified for the extendedindustrial temperature range (−40°C to +125°C). The AD8628is available in tiny TSOT-23, SOT-23, and the 8-lead narrowSOIC plastic packages . The AD8629 is available in the standard8-lead narrow SOIC and MSOP plastic packages . The AD8630quad amplifier is available in 14-lead narrow SOIC and TSSOPplastic packages .
