GENERAL DESCRIPTION

This amplifier has ultralow offset, drift, and bias current.

The AD8628/AD8629/AD8630 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

(±±.35 V to ±2.5 V dual supply).

The AD8628/AD8629/AD8630 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/

AD8629/AD8630 greatly reduce the digital switching noise

found in most chopper-stabilized amplifiers.

The AD8628/AD8629/AD8630 are specified for the extended

industrial temperature range (−40°C to +±25°C). The AD8628

is available in tiny 5-lead TSOT, 5-lead SOT-23, and 8-lead

narrow SOIC plastic packages. The AD8629 is available in the

standard 8-lead narrow SOIC and MSOP plastic packages. The

AD8630 quad amplifier is available in ±4-lead narrow SOIC and

±4-lead TSSOP plastic packages. See the Ordering Guide for

automotive grades.

With an offset voltage of only ± μV, drift of less than 0.005 ꢀV/°C,

and noise of only 0.5 μV p-p (0 Hz to ±0 Hz), the AD8628/

AD8629/AD8630 are suited for applications where error

sources cannot be tolerated. Position and pressure sensors,

medical equipment, and strain gage amplifiers benefit greatly

from nearly zero drift over their operating temperature range.

Many systems can take advantage of the rail-to-rail input and

output swings provided by the AD8628/AD8629/AD8630 to

reduce input biasing complexity and maximize SNR.
