APPLICATIONS Instrumentation IF and baseband amplifiers Active filters ADC drivers DAC buffers GENERAL DESCRIPTION
The AD8045 is a unity-gain stable voltage feedback amplifier paddle that provides a low thermal resistance path to the with ultralow distortion, low noise, and high slew rate. With a printed circuit board (PCB). This enables more efficient heat spurious-free dynamic range of −90 dBc at 20 MHz, the AD8045 is transfer and increases reliability. The AD8045 works over the an ideal solution in a variety of applications, including ultrasound, extended industrial temperature range (−40°C to +125°C). automated test equipment (ATE), active filters, and analog-to-
