36 V Precision, 2.8 nV/√Hz Rail-to-Rail Output Op Amp
(AD8675)
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.
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.
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 am-
plifier. Precision instrumentation, PLL, and other precision filter circuits, position and pressure sensors, medical in-
strumentation, 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 smaller packages and low power consumption afforded by the AD8675 allow maximum channel density or
minimum board size for space-critical equipment.
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.
