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.
The AD8675 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 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
amplifier. Precision instrumentation, PLL, and other precision
filter circuits, position and pressure sensors, medical instru-
mentation, 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 MSOP-8, and the popular 8-lead, narrow SOIC, lead-
free packages. MSOP packaged devices are only available in tape
and reel format.
