GENERAL DESCRIPTION

The AD8675 precision operational amplifier has ultralow offset,

drift, and voltage noise combined with very low input bias currents

over the full operating temperature range. The AD8675 is a

precision, wide bandwidth op amp featuring rail-to-rail output

swings and very low noise. Operation is fully specified from

5 V to 15 V.

take advantage of the low noise, dc precision, and rail-to-rail

output swing provided by the AD8675 to maximize SNR and

dynamic range.

The smaller packages and low power consumption afforded by

the AD8675 allow maximum channel density or minimum

board size for space-critical equipment.

The AD8675 features a rail-to-rail output like that of the OP184,

but with wide bandwidth and even lower voltage noise, combined

with the precision and low power consumption like that of the

industry-standard OP07 amplifier. Unlike other low noise, rail-

to-rail op amps, the AD8675 has very low input bias current

and low input current noise.

The AD8675 is specified for the extended industrial temperature

range (−40°C to +125°C). The AD8675 amplifier is available in

the tiny 8-lead MSOP, and the popular 8-lead, narrow SOIC,

RoHS compliant packages. MSOP packaged devices are only

available in tape and reel format.

For the dual version of this ultraprecision, rail-to-rail op amp,

see the AD8676 data sheet.

With typical offset voltage of only 10 µV, offset drift of 0.2 µV/°C,

and noise of only 0.10 μV p-p (0.1 Hz to 10 Hz), the AD8675 is

perfectly suited for applications where large error sources cannot

be tolerated. For applications with even lower offset tolerances,

the proprietary nulling capability allows a combination of both

device and system offset errors up to 3.5 mV (referred to the

input) to be compensated externally. Unlike previous circuits,

the AD8675 accommodates this adjustment without adversely

affecting the offset drift, CMRR, and PSRR of the amplifier.

Precision instrumentation, PLL, and other precision filter circuits,

position and pressure sensors, medical instrumentation, and

strain gage amplifiers benefit greatly from the very low noise,

low input bias current, and wide bandwidth. Many systems can

The AD8675 and AD8676 are members of a growing series of

low noise op amps offered by Analog Devices, Inc.
