Features and Benefits

  • Enables easy evaluation of the ADA4870
  • Single-supply or dual-supply operation
  • Robust thermal management

Product Details

The ADA4870 is a 40 V, unity-gain stable, high speed current feedback amplifier capable of delivering 1 A of output current from a 40 V supply. Manufactured using the Analog Devices, Inc., proprietary high voltage XFCB process, the innovative architecture of the ADA4870 enables high output power, high speed signal processing solutions in a variety of demanding applications.

The ADA4870 is ideal for driving high voltage power FETs, piezoelectric transducers, PIN diodes, and a variety of other demanding applications that require high speed from high supply voltage and high current output.

The ADA4870 is available in a Chip Scale package (LFCSP) featuring an exposed thermal slug that provides high thermal conductivity to the printed circuit board (PCB) and heat sink enabling efficient heat transfer for improved reliability in demanding environments. The ADA4870 operates over the industrial temperature range of −40°C to +85°C.

The EVAL-ADA4870EBZ evaluation board provides a platform for quick and easy evaluation of the ADA4870.
