It operates from a single 3V to 3.6V supply for both analog and digital domains, with a serial data interface. Typical SNR is 94 dB for both ADC and DAC paths, while dynamic range reaches 105 dB (ADC) and 106 dB (DAC). The -40°C to 105°C operating temperature range qualifies it for automotive cabin and under-hood audio processing — infotainment head units, active noise cancellation, and multi-zone audio systems. ## What the key ratings mean for your BOM The 4 ADC / 8 DAC channel count handles four inputs and drives eight outputs. The 105 dB / 106 dB dynamic range sets the noise floor for 24-bit audio. ## Lifecycle and sourcing The AD1938WBSTZ-RL carries an Active product status per the manufacturer, with ROHS3 compliance.","metaTitle":"AD1938WBSTZ-RL Automotive Audio Codec, 24-bit 4 ADC / 8 DAC","metaDescription":"ADI AD1938WBSTZ-RL automotive-grade audio codec: 24-bit resolution, 4 ADC / 8 DAC channels, 105 dB dynamic range, -40°C to 105°C, 48-LQFP.
