概述

Description

PCM1862QDBTRQ1 is Texas Instruments’ automotive-grade development/evaluation board for the PCM1862Q1 device. The PCM1862Q1 itself is a dual-channel, 24‑bit delta‑sigma ADC used to convert analog audio signals into digital data (I2S/PCM digital interface) for automotive audio and voice applications. The “Q1” suffix denotes automotive qualification (AEC-Q100) for use in vehicles, and “DB” indicates a development board version to ease evaluation and reference designs. The board provides the necessary power, analog input paths, and a digital interface to host MCUs or processors, enabling quick testing of audio front-end designs (e.g., microphones, line inputs) in automotive environments. In short: it’s TI’s automotive-grade two-channel ADC plus a ready-to-use board for rapid evaluation and integration into vehicle audio systems.
