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 ꢀ to ±±5 ꢀ.

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 instrumen-

tation, 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 AD8675 to maximize

SNR and dynamic range.

The AD8675 features a rail-to-rail output like that of the OP±84,

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

bined 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 smaller packages and low power consumption afforded by

the AD8675 allow maximum channel density or minimum

board size for space-critical equipment.

With typical offset voltage of only ±0 μꢀ, offset drift of 0.2 μꢀ/°C,

and noise of only 0.±0 ꢁꢀ p-p (0.± Hz to ±0 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 mꢀ (referred

The AD8675 is specified for the extended industrial temperature

range (−40°C to +±25°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.
