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
Unit gain (0dB) configurable via serial port
Dynamic performance:
Equivalent input noise (ZS=150Ω, gain=30dB): -123dBu
Total harmonic distortion plus noise (THD+N, gain=30dB): 0.0006%
Zero-crossing detection technology minimises audible ghosting during gain switching
Integrated DC servo circuit effectively suppresses output bias voltage
Common-mode servo circuit significantly enhances common-mode rejection ratio (CMRR)
Four-wire serial control interface features:
Easily connects to microprocessor or DSP serial port
Supports daisy-chain connection of PGA2505 devices
Over-range output pin provides clipping indication
Four general-purpose digital output pins
±5V power supply operation
Available in SSOP-24 package

PGA2505EVMV2 Features:
Accepts XLR or TRS balanced input connections
Configurable front-end circuit options for prototyping pads and filters
