GENERAL DESCRIPTION
rail-to-rail input and output, single-supply amplifiers. They
feature very low offset voltage, low input voltage and current
noise, and wide signal bandwidth. They use the Analog Devices,
Inc. patented DigiTrim trimming technique, which achieves
superior precision without laser trimming.
The combination of low offsets, low noise, very low input bias
currents, and high speed makes these amplifiers useful in a
wide variety of applications. Filters, integrators, photodiode
amplifiers, and high impedance sensors all benefit from the
combination of performance features. Audio and other ac
applications benefit from the wide bandwidth and low
distortion. Applications for these amplifiers include optical
control loops, portable and loop-powered instrumentation,
and audio amplification for portable devices.
extended industrial temperature range (40°C to +125°C). The
AD8605 single is available in 5-lead SOT-23 and 5-ball WLCSP
8-ball WLSCP, and a narrow SOIC surface-mounted package.
a narrow 14-lead SOIC package. The 5-ball and 8-ball WLCSP
offer the smallest available footprint for any surface-mounted
operational amplifier. The WLCSP, SOT-23, MSOP, and TSSOP
versions are available in tape-and-reel only.
