PCM3794ARHBT Description

Short technical summary and product information.

The Texas Instruments PCM3794ARHBT is a very low-power stereo CODEC designed for audio applications. It offers 16-bit resolution for both analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC), with typical SNR values of 90 dB for ADCs and 93 dB for DACs.

 

This device supports a maximum sampling rate of 50 kHz and features a serial data interface compatible with DSP, I2S, L, and R formats. Control interfaces include I2C and SPI. The CODEC provides 6 analog inputs and 3 analog outputs, along with features like automatic level control (ALC) and notch filters.

 

Operating within a temperature range of -40°C to 85°C, the PCM3794ARHBT is housed in a 32-VQFN (5x5 mm) package. Its power supply voltage ranges from 2.4V to 3.6V for analog sections and 1.71V to 3.6V for digital sections. Low power dissipation is a key characteristic, with minimal consumption in power-down mode.

 

Applications for this CODEC include portable audio players, cellular phones, video camcorders, digital cameras, and PMPs/DMBs, where high-quality audio processing is required in a compact and power-efficient form factor.
