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 pin out for the LFCSP, which improves second harmonic distortion and simplifies the layout of the circuit board. The AD8045 amplifier is available in a 3 mm x 3 mm LFCSP as well as the standard 8-lead SOIC. Both packages feature an exposed paddle that provides a low thermal resistance path to the PCB. This enables a more efficient heat transfer, and increases reliability. The AD8045 works over the extended industrial temperature range (-40°C to +125°C).
