Overview

Features and Benefits

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

Product Details

The ADA4870 is a unity-gain stable, high speed current feedback amplifier capable of delivering 1 A of output current and 2500 V/μs slew rate from a 40 V supply. Manufactured using the Analog Devices, Inc., proprietary high voltage extra fast complementary bipolar (XFCB) process, the innovative architecture of the ADA4870 enables high output power, high speed signal processing solutions in applications that require driving a low impedance load.

The ADA4870 is ideal for driving high voltage power FETs, piezoelectric transducers, P-type intrinsic N-type (PIN) material diodes, CCD panels, and a variety of other demanding applications that require high speed from high supply voltage and high output current.

The ADA4870 is available in a 48-lead frame chip scale package (LFCSP) with an exposed pad that provides high thermal conductivity to the printed circuit board (PCB), enabling efficient heat transfer for improved performance and 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. Figure 1 shows the top side of the evaluation board. Figure 2 in the user guide shows the bottom side of the board with the large exposed copper area for applying a heat sink as needed.
