GENERAL DESCRIPTION

The AD8676 precision operational amplifier offers ultralow

offset, drift, and voltage noise combined with very low input

bias currents over the full operating temperature range. The

AD8676 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.

The AD8676 features a rail-to-rail output like that of the OP184,

but with wide bandwidth and even lower voltage noise, com-

bined with the precision and low power consumption like that

of the industry-standard

noise, rail-to-rail op amps, the AD8676 has very low input bias

current and low input current noise.

With typical offset voltage of only 12 μV, offset drift of 0.2 μV/°C,

and noise of only 0.10 μV p-p (0.1 Hz to 10 Hz), the AD8676 is

perfectly suited for applications where large error sources

cannot be tolerated. 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 take advantage of the low noise, dc precision,

and rail-to-rail output swing provided by the AD8676 to maxi-

mize SNR and dynamic range.

The smaller packages and low power consumption afforded by

the AD8676 allow maximum channel density or minimum

board size for space-critical equipment.

The AD8676 is specified for the extended industrial temperature

range (−40°C to +125°C). The AD8676 is available in the 8-lead

MSOP, and the popular 8-lead, narrow SOIC; both of which are

lead-free packages. MSOP packaged devices are only available

in tape and reel format.
