Texas Instruments PCM3010DBG4

Overview

PCM3010DBG4 from Texas Instruments is a 24-bit stereo audio codec IC integrating delta-sigma ADC and DAC with single-ended analog I/O, 96-kHz max ADC sampling, 192-kHz max DAC sampling, ±0.05 dB pass-band ripple in ADC decimation filter, and dual power supplies (5 V analog, 3.3 V digital). It serves as the core audio conversion engine in cost-sensitive consumer audio systems such as DVD recorders and PC audio interfaces.

For engineers reviewing the PCM3010DBG4 datasheet, PCM3010DBG4 pinout, PCM3010DBG4 application, or PCM3010DBG4 equivalent, key selection considerations include its 24-pin SSOP package, 24-bit resolution, 100 dB typical SNR (ADC), 104 dB typical SNR (DAC), and support for I²S/Left-justified/Right-justified data formats with programmable de-emphasis.

Technical Context

The PCM3010DBG4 implements a fifth-order delta-sigma modulator architecture for both ADC and DAC paths, with 64× oversampling on the ADC side and 8× interpolation plus multilevel (8-level) quantization on the DAC side. Its ADC includes an on-chip antialiasing filter and high-pass filter (0.84 Hz at 44.1 kHz), while the DAC integrates an analog low-pass filter and digital de-emphasis for 32/44.1/48 kHz sampling rates.

It supports six system clock ratios (128 f_S to 768 f_S) and operates across 16–96 kHz ADC and 16–192 kHz DAC sampling ranges. Power-down mode disables both ADC and DAC simultaneously, reducing dissipation to 1 mW, and all digital inputs are 5-V tolerant Schmitt-trigger types with internal pulldown resistors.

FAQ

What is the maximum DAC sampling rate supported by the PCM3010DBG4?

The PCM3010DBG4 supports a maximum DAC sampling rate of 192 kHz, enabling high-resolution audio playback compatible with DVD-Audio and studio-grade digital sources. This capability is available only when the system clock is set to 128 f_S or 192 f_S, and the ADC is automatically disabled under those conditions. The PCM3010DBG4 maintains full 24-bit resolution and 104 dB SNR even at 192 kHz.

Does the PCM3010DBG4 require external analog filters?

No, the PCM3010DBG4 integrates both antialiasing filters on the ADC side and analog low-pass filters on the DAC side, eliminating the need for external RC or active filter networks. Its on-chip filters meet EIAJ standards for pass-band ripple (±0.03 dB for DAC, ±0.05 dB for ADC) and stop-band attenuation (–50 dB for DAC, –65 dB for ADC), directly supporting line-level single-ended 3 V_p-p operation.

How is de-emphasis configured on the PCM3010DBG4?

De-emphasis on the PCM3010DBG4 is configured using the DEMP0 and DEMP1 pins, which are hardware-selectable inputs supporting 32 kHz, 44.1 kHz, and 48 kHz standards per EIAJ. No register programming or firmware interaction is required - the setting is latched at power-up or reset. The PCM3010DBG4 applies de-emphasis digitally within the DAC path with ±0.1 dB error, preserving compatibility with legacy CD recordings.

What power supply configuration does the PCM3010DBG4 require?

The PCM3010DBG4 requires three independent supplies: 5 V for ADC analog (VCC1), 5 V for DAC analog (VCC2), and 3.3 V for digital core (VDD). AGND1, AGND2, and DGND must be kept separate and joined at a single point to minimize ground bounce. The PCM3010DBG4 draws 40 mA total at 44.1 kHz and drops to 1 mW in power-down mode when PDWN is asserted.

Is the PCM3010DBG4 pin-compatible with other members of the PCM30xx family?

Yes, the PCM3010DBG4 shares identical pinout and package (24-pin SSOP) with PCM3002, PCM3003, and PCM3008 variants. However, functional differences exist - notably, PCM3002 lacks DAC de-emphasis, PCM3003 omits the high-pass filter, and PCM3008 adds digital volume control. System-level validation is required before substitution, as register maps and default power-on states differ across the family.
