Product details
Overview
PCM5310PAP from Texas Instruments is a 24-bit, 96-/192-kHz asynchronous 4-channel/4-channel audio codec with integrated 2-VRMS line drivers, headphone amplifier, six configurable audio interface ports, and analog multiplexer. It delivers 100 dB DAC SNR, 0.01% THD+N at 48 kHz, and supports I²S/left/right-justified formats for digital TV, DVD recorder, and IP-STB applications.
For engineers reviewing the PCM5310PAP datasheet, PCM5310PAP pinout, PCM5310PAP application, or PCM5310PAP equivalent, key selection considerations include its dual stereo ADC/DAC architecture, 6-port digital audio mux/bypass capability, 2.4-VRMS line output option, headphone short-circuit protection, and I²C-configurable analog gain/volume control across all signal paths.
Technical Context
The PCM5310PAP implements two independent stereo delta-sigma ADCs (up to 96 kHz) and two stereo DACs (up to 192 kHz), each with programmable interpolation/decimation filters, de-emphasis, and high-pass filtering. Its six audio interface ports support asynchronous operation with automatic system clock rate detection (128–768×fS) and configurable master/slave modes per port.
On-chip analog routing includes a 6×2 stereo input mux feeding dual ADCs, and flexible analog output muxing enabling any DAC channel or analog input source to drive LO1/LO2/HP outputs. All analog paths feature digitally controlled gain stages-9/6/3/0 dB for inputs, 0/–0.5/–1.0 dB for line outputs, and –70 to +12 dB in 1-dB steps for headphones-with zero-crossing mute and pop-noise reduction.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCM3060PAP | 24-bit, 96-kHz stereo ADC/DAC only; no headphone amp; 4 audio ports; lower power (180 mW) | Lacks headphone driver and 2 extra interface ports-suitable for cost-sensitive STB designs without front-panel audio | Select when system uses external headphone amp and requires fewer digital audio connections |
| TLV320AIC3254IRGZT | Low-power 24-bit, 192-kHz stereo codec; integrated miniDSP; 1.8-V I/O; smaller 48-QFN package | Targeted at portable devices; lacks 2-VRMS line drivers and 6-port flexibility-requires external amplification for line-level outputs | Select for battery-powered or space-constrained applications where DSP programmability outweighs high-voltage analog output needs |
Compared with PCM3060PAP and TLV320AIC3254IRGZT, PCM5310PAP uniquely combines 4-channel conversion, 6-port digital flexibility, 2.4-VRMS line drive, and integrated headphone amplification-making it optimal for fixed-installation digital video equipment requiring full analog I/O consolidation.

FAQ
What is the maximum sampling rate supported by the PCM5310PAP DAC and ADC?
The PCM5310PAP DAC supports up to 192 kHz sampling rate, while the ADC supports up to 96 kHz. These rates are confirmed in the device's electrical characteristics table and functional description, with corresponding system clock requirements (e.g., 768×fS for DAC at 192 kHz). The PCM5310PAP achieves this using delta-sigma modulation with programmable oversampling ratios and digital filtering tailored per converter path.
Does the PCM5310PAP support I²S, left-justified, and right-justified audio data formats?
Yes, the PCM5310PAP supports all three standard serial audio formats-I²S, left-justified, and right-justified-across all six digital audio interface ports. This is explicitly stated in the device description and electrical characteristics section. Each port (SCKx/BCKx/LRCKx/DATAx) can be independently configured via I²C registers for format, bit length (16/24-bit), and master/slave mode.
How does the PCM5310PAP handle analog input gain control and what are the available settings?
The PCM5310PAP provides programmable analog gain control on all six stereo input channels via integrated PGAs. Gain settings are 0 dB, 3 dB, 6 dB, or 9 dB, selected per channel pair through I²C registers (AG1L/R, AG2L/R). This allows optimization of signal-to-noise ratio for varying input levels without external amplification-confirmed in the "Analog Inputs" detailed description and Table 1 register map.
What is the purpose of the VCCH supply pin on the PCM5310PAP and what voltage does it require?
The VCCH pin (Pin 18) supplies the 2-VRMS line driver circuitry and must be operated at 9.0 V ±0.45 V (8.55–9.45 V), as specified in the Recommended Operating Conditions table. This higher voltage rail enables the line outputs to achieve 2.4 VRMS full-scale swing when configured, distinguishing PCM5310PAP from standard 3.3-V codecs and eliminating need for external boost stages in line-output paths.
Can the PCM5310PAP route analog inputs directly to analog outputs without digital conversion?
Yes, the PCM5310PAP supports analog bypass mode, allowing any analog input (e.g., AIN1L/R) to be routed directly to line or headphone outputs without passing through ADC/DAC conversion. This path includes analog gain control and is characterized for 0.003% THD+N and 100 dB SNR-documented in the "ANALOG INPUT TO ANALOG OUTPUT PATH (BYPASS)" section of the Electrical Characteristics table.
