Texas Instruments PGA2505EVMV2 Evaluation Module

Texas Instruments PGA2505EVMV2 Evaluation Module is designed to evaluate a digitally-controlled microphone preamplifier with a USB interface. The programmable gain amplifier can be programmed to either pass through the signal at unity gain, or apply 9dB to 60dB (3dB steps) of gain to the input signal.

Features

  • Accepts either XLR or TRS balanced input connections
  • Configurable front-end circuit options for prototyping pads and filters
  • Designed to evaluate PGA2505 microphone preamplifiers
  • XLR and TRS balanced output with flexible output loading options
  • LED indicators for GPOs and the over-range output
  • Common-Mode Voltage Input (VCOMIN) pin
  • Includes applications software that is compatible with personal computers that include a built-in USB port
  • Requires +5V and -5V analog supplies, as well as a +5V digital supply
    • Leave the +5V digital supply (VCC) unconnected if using the MSP-EXP430F5529LP
