PCM6260QRTVRQ1

The Texas Instruments PCM6260-Q1 is a high-performance, 6-channel audio Analog-to-Digital Converter (ADC) designed for automotive applications. It supports analog input signals up to 10 VRMS and features a line differential input dynamic range of 110 dB, with a THD+N of -95 dB. The device is AEC-Q100 qualified for automotive applications, operating within a temperature range of -40°C to +125°C.

Key features include programmable channel settings with gain up to 42 dB and digital volume control from -100 dB to 27 dB. It offers a programmable microphone bias voltage from 5 V to 9 V with an integrated boost converter and includes input fault diagnostics for open or shorted inputs. The ADC supports sample rates from 8 kHz to 768 kHz and provides flexible audio serial data interface formats including TDM, I2S, and left-justified (LJ), with word lengths from 16 to 32 bits.

Controlled via I2C or SPI interfaces, the PCM6260-Q1 operates on a single 3.3-V supply with I/O supply options of 3.3 V or 1.8 V. It is available in a 32-WQFN (5x5) package suitable for surface mounting. The device is designed for applications such as automotive active noise cancellation, head units, digital cockpit processing, and external amplifiers.
