GENERAL DESCRIPTION
The AD8045 is a unity gain stable voltage feedback amplifier
with ultralow distortion, low noise, and high slew rate. With a
spurious-free dynamic range of 90 dBc @ 20 MHz, the
AD8045 is an ideal solution in a variety of applications,
including ultrasound, ATE, active filters, and ADC drivers.
ADI’s proprietary next generation XFCB process and innovative
architecture enables such high performance amplifiers.
The AD8045 features a low distortion pinout for the LFCSP,
which improves second harmonic distortion and simplifies the
layout of the circuit board.
The AD8045 has 1 GHz bandwidth, 1350 V/s slew rate, and
settles to 0.1% in 7.5 ns. With a wide supply voltage range (3.3 V
to 12 V) and low offset voltage (200 V), the AD8045 is an ideal
candidate for systems that require high dynamic range, preci-
sion, and high speed.
The AD8045 amplifier is available in a 3 mm × 3 mm LFCSP
and the standard 8-lead SOIC. Both packages feature an
exposed paddle that provides a low thermal resistance path to
the PCB. This enables more efficient heat transfer, and increases
reliability. The AD8045 works over the extended industrial
temperature range (40°C to +125°C).
