GENERAL DESCRIPTION

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).

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/µs 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 µV), the AD8045 is an ideal

candidate for systems that require high dynamic range, preci-

sion, and high speed.
