GENERAL DESCRIPTION

The AD8671, AD8672 and AD8674 are precision

single, dual and quad amplifiers featuring very low

noise, very low offset voltage and drift, low input bias

current, 10Mhz bandwidth and low power

consumption. Outputs are stable with capacitive loads

of over 100pF. Supply current is less than 3 mA per

amplifier at 30V.

Applications for these amplifiers include high quality

PLL filters, instrumentation--thermocouple, RTD,

strain-bridge and other sensor signal conditioning--

precision filters and professional quality audio.

The AD8671, AD8672 and AD8674 are specified

over the extended industrial (-40° to +125°C)

temperature range. The AD8671, single, is available

in the 8-lead MSOP and 8-lead SOIC packages.

The AD8672, dual, is available in the 8-lead MSOP

and 8-lead SOIC packages. The AD8674, quad, is

available in 14-lead TSSOP and narrow 14-lead SO

packages. Surface mount devices in TSSOP and

MSOP packages are available in tape and reel only.
