EVAL-ADUM4195

Evaluating the ADuM4195 Isolated Amplifier with Adjustable Gain and Single-Ended Output

特性和优点

  • ADuM4195 isolated amplifier in a wide body SOIC-16 package
  • ADuM6028-5BRIZ isolated on-board power supply
  • Maximum 1000 V DC preconfigured input
  • Configurable for AC voltage input

产品详情

The EVAL-ADuM4195EBZ is a compact isolated DC and AC (configurable) voltage monitoring board with an isolated on-board power supply to facilitate the setup and testing of the performance characteristics of the ADuM4195.

On the input side of the board (right-hand side), the high-voltage input connector P1 is preconfigured to accept up to 1 kV DC. The internal operational amplifier (op amp) on the input side is connected in a voltage-follower configuration. On the output side of the board (left-hand side), the overall output of the ADuM4195 is directly accessible on P6 (preconfigured) or can be first-order low-pass filtered by adding a resistor and capacitor. A single 5 V DC supply is sufficient to power both the input and output side of the board, while the optional power disable (PDIS) input can be used to disable the on-board isolated power supply in applications where low-power consumption is at a premium. Full details about the device are available in the ADuM4195 data sheet, which must be consulted when using the EVAL-ADuM4195EBZ.
