TLV320DAC23IRHDR

ADCs/DACs - Special Purpose Overview

The TLV320DAC23 is a high-performance stereo digital-to-analog converter (DAC) featuring multibit sigma-delta technology with integrated oversampling digital interpolation filters. It supports data word lengths of 16, 20, 24, and 32 bits at sampling rates from 8 kHz to 96 kHz. The device achieves up to 100 dBA SNR and includes a highly efficient linear headphone amplifier capable of delivering 30 mW per channel into 32 Ω. Analog features comprise stereo line inputs with an analog bypass path and stereo line outputs. Power consumption is approximately 18 mW during playback, with standby power below 150 µW. It operates on a 1.42 V–3.6 V digital supply and a 2.7 V–3.6 V analog supply.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific package variant required for the design: 32-pin MicroStar Junior (GQE), 28-pin TSSOP (PW), or 28-pin QFN (RHD). Confirm the temperature grade matches the application environment, as the IRHDR suffix indicates the industrial range (-40°C to 85°C). Ensure the ordering suffix aligns with the desired packaging format specified in the manufacturer's documentation.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a glueless interface to Texas Instruments C54x DSPs is required, utilizing optimized oversample rates of 250 fs and 272 fs. Choose the RHD package for space-constrained designs requiring a 25 mm² footprint. Ensure the system clock can be derived from a single 12-MHz crystal to support both 44.1 kHz and 48 kHz sampling rates directly.

ADCs/DACs - Special Purpose Part Context

The TLV320DAC23 belongs to the Texas Instruments TLV320 family of audio products. It is designed specifically for portable applications where low power consumption and small board area are critical. The device integrates control interfaces compatible with SPI and 2-wire protocols, allowing flexible software control over its extensive register map for volume, mute, and power management functions.
