PGA2505EVMV2 Evaluation Module (EVM) provides a convenient platform for assessing the performance and characteristics of the PGA2505 product. The PGA2505 is a digitally controlled microphone preamplifier with a USB interface. This programmable gain amplifier can be configured to pass signals at unity gain or apply 9dB to 60dB of gain (in 3dB steps) to the input signal. Gain and support functions are controlled via the MSP430F5529 microcontroller and the PGA2505EVMV2 graphical user interface (GUI).

Products supported by the PGA2505EVMV2:
Dedicated Audio Amplifiers
PGA2505 — Gain Range: 0dB and 9dB to 60dB (3dB steps)
Features:
Fully differential input-to-output architecture
Digital gain control via SPI™:
Gain range: 9dB to 60dB, 3dB per step
