Product details
Overview
PCM3010DB 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-supply operation (5 V analog / 3.3 V digital). It serves as the core audio conversion engine in cost-sensitive consumer audio systems requiring high SNR and low THD+N.
For engineers reviewing the PCM3010DB datasheet, PCM3010DB pinout, PCM3010DB application, or PCM3010DB equivalent, this page delivers verified technical context, exact pin functions, real-world application mappings, and validated alternative parts for audio subsystem design, BOM optimization, and legacy system replacement.
Technical Context
The PCM3010DB implements fifth-order delta-sigma modulation in its ADC path with 64× oversampling and integrated antialiasing filtering, plus a 1/128 or 1/64 decimation filter with on-chip high-pass filtering at 0.84 Hz (fS = 44.1 kHz). Its DAC uses an 8-level multilevel delta-sigma modulator with 8× oversampling interpolation and digital de-emphasis support for 32/44.1/48 kHz rates.
It supports four serial audio interface formats (I²S, left-justified, right-justified), accepts 16- or 24-bit data, and operates with system clocks of 128 fS to 768 fS - automatically detecting clock ratio. ADC is disabled at 192 kHz sampling (DAC-only mode), and power-down control (PDWN) simultaneously disables both converter blocks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ADC Resolution | 24-bit delta-sigma with 64× oversampling - enables >100 dB dynamic range and precise low-level signal capture. |
| DAC Max Sampling Rate | 192 kHz - supports high-resolution playback including DVD-Audio and studio-grade monitoring paths. |
| THD+N (ADC) | –95 dB typical at 44.1 kHz - ensures minimal harmonic distortion in recording chains for clean microphone or line input digitization. |
| SNR (DAC) | 104 dB typical at 44.1 kHz - delivers wide noise margin for high-fidelity headphone and speaker driver stages. |
| Analog Supply | 5 V (VCC1/VCC2) - requires stable low-noise analog rail; separate AGND1/AGND2 pins enable independent ADC/DAC ground return paths. |
| Digital Supply | 3.3 V (VDD) - compatible with modern microcontrollers and DSPs; DGND isolation prevents digital noise coupling into analog sections. |
| Audio Interface | I²S, left/right-justified, MSB-first, 2's complement - interoperable with TI C5000/C6000, ARM-based audio SoCs, and FPGA-based serializers. |
Pinout & Package
Package: 24-pin SSOP (DB package code), lead-free, 0.635 mm pitch, 8.2 mm × 3.9 mm footprint - suitable for compact consumer PCB layouts with thermal resistance θJA = 100°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINL / VINR | ADC analog input (L/R) | Single-ended voltage inputs accepting 3 Vp-p; internal reference buffer eliminates need for external op-amp front-end. |
| VOUTL / VOUTR | DAC analog output (L/R) | Single-ended 3 Vp-p outputs referenced to VCOM (0.5 × VCC2); integrated analog LPF reduces external component count. |
| VREF1 / VREF2 | ADC reference decoupling | Decoupling nodes for internal 0.5 × VCC1 reference - require 10 µF + 0.1 µF ceramic capacitors per pin for stable full-scale accuracy. |
| VCOM | DAC common-mode voltage | Fixed at 0.5 × VCC2; must be decoupled with 10 µF capacitor to minimize DAC output offset and crosstalk. |
| SCKI | System clock input | Accepts 4–50 MHz clock (128 fS to 768 fS); Schmitt-trigger input tolerates 5 V - simplifies clock tree design from crystal oscillator or PLL. |
| LRCK / BCK / DIN / DOUT | Audio serial interface | Standard I²S timing; BCK up to 6.144 MHz at 192 kHz - supports TDM expansion via external logic if needed. |
| FMT0 / FMT1 | Data format select | 2-bit parallel control of audio format (I²S/left/right-justified) and bit length (16/24) - enables runtime reconfiguration without firmware update. |
| DEMP0 / DEMP1 | De-emphasis select | Configures digital de-emphasis for 32/44.1/48 kHz playback - critical for CD-standard audio compliance and legacy media compatibility. |
| PDWN | Power-down control | Active-low input; asserts simultaneous ADC+DAC shutdown with <1 mW quiescent power - essential for battery-powered portable audio. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated analog filters | On-chip antialiasing (ADC) and low-pass (DAC) filters eliminate 4–6 external op-amps and RC networks per channel. |
| High-pass filter (HPF) | 0.84 Hz cutoff at 44.1 kHz - removes DC offset and subsonic rumble without affecting audible bass response. |
| Dual independent analog grounds | AGND1 (ADC) and AGND2 (DAC) allow separate ground plane routing - reduces inter-channel crosstalk to 98 dB at 44.1 kHz. |
| Flexible clock detection | Auto-senses 128–768 fS ratios - enables single hardware design across 32–192 kHz sample rates without configuration registers. |
| Power-down fade control | Controlled DAC fade-out/in sequence (tDACDLY1 = 2100/fS) prevents pop/click artifacts during sleep/wake transitions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AK4552VN | 24-bit, 96-kHz ADC/DAC; single 3.3-V supply; no integrated analog filters; requires external op-amps for I/O buffering. | Better suited for space-constrained designs where board area permits external analog components; lacks de-emphasis and HPF. | Select when system already includes precision op-amps and requires unified 3.3-V rail; avoid if minimizing BOM count or meeting CD playback specs is critical. |
| CS4272-KQZ | 24-bit, 192-kHz ADC/DAC; 5-V analog + 3.3-V digital supplies; integrated analog filters; supports S/PDIF I/O in addition to I²S. | Enables digital audio passthrough (e.g., Dolby Digital) alongside analog conversion; higher SNR (110 dB) but larger 48-QFN package. | Choose for AV receivers needing S/PDIF interface and extended dynamic range; not drop-in due to pin count, package, and register map differences. |
Compared with AK4552VN and CS4272-KQZ, the PCM3010DB offers the optimal balance of integrated analog functionality, compact SSOP packaging, and CD-standard de-emphasis - making it ideal for cost-driven consumer recorders and PC audio where external component count and layout area are primary constraints.

FAQ
What is the maximum DAC sampling rate supported by the PCM3010DB?
The PCM3010DB supports a maximum DAC sampling rate of 192 kHz, enabling high-resolution audio playback for DVD-Audio and studio monitoring applications. At this rate, the ADC is disabled per datasheet specification (SLES055, p.21), and the system clock must be set to 128 fS or 192 fS - confirmed in Table 1 and "system clock" section of the PCM3010DB datasheet.
Does the PCM3010DB include integrated analog filters?
Yes, the PCM3010DB integrates both an antialiasing filter in the ADC path and an analog low-pass filter in the DAC path. These eliminate the need for external RC networks or op-amp-based filters, reducing BOM count and PCB area. Performance is specified with –0.03 dB ripple at 20 kHz and –0.20 dB at 44 kHz for the DAC LPF (SLES055, p.8).
How does the PCM3010DB handle digital de-emphasis?
The PCM3010DB provides hardware-configurable digital de-emphasis for 32 kHz, 44.1 kHz, and 48 kHz sampling rates using DEMP0/DEMP1 pins. De-emphasis error is ±0.1 dB (SLES055, p.8), ensuring compliance with CD audio standards. This function operates entirely in the digital domain prior to DAC conversion.
What are the power supply requirements for the PCM3010DB?
The PCM3010DB requires dual supplies: 4.5–5.5 V for analog sections (VCC1/VCC2) and 3.0–3.6 V for digital (VDD). Separate AGND1, AGND2, and DGND pins are mandatory for optimal noise isolation. Supply current is 40 mA (ADC+DAC active, 44.1 kHz) and drops to 1 mW in power-down mode (SLES055, p.8).
Can the PCM3010DB operate with a single 3.3-V supply?
No, the PCM3010DB cannot operate with a single 3.3-V supply. Its analog circuitry (ADC/DAC cores, reference buffers, analog I/O) requires 5 V (VCC1/VCC2), while only the digital interface (DIN/DOUT/LRCK/BCK) runs from 3.3 V (VDD). Attempting 3.3 V on VCC1/VCC2 violates absolute maximum ratings and will result in failure to meet SNR, THD+N, or full-scale linearity specs.
