PCM1803DBG4

ADCs/DACs - Special Purpose Overview

The PCM1803DBG4 is a stereo audio analog-to-digital converter manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 96 kHz. The device utilizes a delta-sigma architecture with an integrated oversampling decimation filter. It accepts single-ended analog inputs with a peak-to-peak voltage of 3 V. Key performance metrics include a typical total harmonic distortion plus noise (THD+N) of -93 dB, a signal-to-noise ratio (SNR) of 99 dB, and a dynamic range of 99 dB. The component operates within a temperature range of -40°C to +85°C and is housed in a 20-pin SSOP package.
