The Texas Instruments PCM3794ARHBR is a very low-power stereo CODEC designed for audio applications. It integrates a headphone amplifier, notch filters, automatic level control (ALC), and 3D effects.
This device offers 2 analog-to-digital converter (ADC) channels and 2 digital-to-analog converter (DAC) channels, with a resolution of 16 bits. The digital audio interface supports DSP and I2S formats, while control interfaces include I2C and SPI. It features a typical ADC SNR of 90 dB and a DAC SNR of 93 dB.
The PCM3794ARHBR operates within a temperature range of -40°C to 85°C and is available in a 32-VQFN (5x5 mm) surface-mount package. Its analog front-end includes a stereo single-ended input with a multiplexer, a mono differential input, and a stereo programmable gain amplifier with a microphone amplifier. The analog back-end provides stereo/mono line output, stereo/mono headphone amplifier, and stereo/mono digital speaker amplifier (BTL).
Key features include automatic level control for recording, a two-stage programmable notch filter, and a three-band tone control with 3D sound. Power supply voltages range from 1.71V to 3.6V for digital sections and 2.4V to 3.6V for analog and power amplifier sections. Low power dissipation is achieved, with 7 mW in playback and 3.3 µW in power down mode.
