1 Introduction
1.1 Description
The TPA5050 evaluation module (EVM) consists of a single TPA5050 audio delay device, along with other
external components mounted on a printed-circuit board (PCB) that can be used to digitally delay either
the left, right, or both channels by up to 8191 samples (with a 48-kHz sampling rate, that equates to more
than 170 ms of delay).
The TPA5050EVM is designed to work seamlessly with the TI Input USB board, but can function as a
stand-alone board for pass-through testing in any system. All that is required is an I
2
I C controller, and a 5-V supply.
The TPA5050EVM also includes an onboard digital-to-analog controller (DAC), the PCM1606, which can
2
convert I S or left-justified data to an analog out. The analog out is filtered on the board and can be
viewed with a scope probe.
