Overview
The PCM3070IRHBR is a versatile stereo audio codec produced by Texas Instruments. It is designed to offer high flexibility with programmable inputs and outputs, a fully-programmable miniDSP, and fixed predefined as well as parameterizable signal processing blocks. The codec integrates a PLL (Phase-Locked Loop) and LDOs (Low Dropout Regulators), and it supports multiple digital interfaces such as I²C, Serial, and SPI™. This component is housed in a 32-pin VQFN (Very Thin Quad Flat No-Lead) package, making it suitable for a variety of audio applications requiring compact and efficient solutions.
