Renesas DA7210-00UC2

Overview

DA7210-00UC2 from Renesas Electronics is an ultra-low power stereo audio codec IC with integrated capless headphone driver, 100 dB SNR DAC, 96 dB SNR ADC, and programmable 5-band digital EQ - designed for battery-powered portable audio devices operating from a single 1.8 V supply.

For engineers reviewing the DA7210-00UC2 datasheet, DA7210-00UC2 pinout, DA7210-00UC2 application, or DA7210-00UC2 equivalent, key selection considerations include its Class-G capless headphone drive (2×58 mW into 16 Ω), multi-slot I²S/PCM interface supporting 8–96 kHz sample rates, on-chip PLL with audio sample rate matching, and ASSP DSP engine for wind noise suppression and 3D sound processing.

Technical Context

The DA7210-00UC2 implements a dual-path signal architecture: an input chain with eight analogue inputs (differential/single-ended mic/line), variable-gain preamps, and ALC with programmable attack/decay; and an output chain featuring independent stereo DACs, soft mute, mixers, line-out amplifiers, and a Class-G charge-pump headphone driver with short-circuit protection.

Digital audio processing is handled by a configurable GP filter engine supporting acoustic filtering, 5-band parametric EQ (corner frequencies from 50 Hz to 5 kHz), automatic gain control, and voice-mode high-pass filtering (8 kHz/16 kHz). The device supports master/slave I²S/PCM/TDM/DSP modes and uses a 49-ball WL-CSP package with 0.4 mm pitch.

FAQ

What is the primary function of the DA7210-00UC2 in an audio system?

The DA7210-00UC2 serves as a complete stereo audio codec IC, integrating high-performance ADC and DAC paths, a capless Class-G headphone amplifier, programmable digital signal processing (including 5-band EQ and wind noise suppression), and flexible digital audio interfaces. It replaces multiple discrete components - such as separate ADC/DAC chips, headphone amps, and DSP units - in portable audio systems, enabling compact, low-power designs with high-fidelity audio capability. Its architecture is optimized for direct connection to microphones, headphones, and SoCs via I²S and I²C.

Does the DA7210-00UC2 support true-ground (capless) headphone outputs?

Yes, the DA7210-00UC2 features a true-ground capless headphone driver using a four-level dynamic charge pump (Class-G topology) that centers output signals around ground. This eliminates the need for large DC-blocking capacitors (typically 220 µF per channel), reducing BOM cost, PCB area, and distortion caused by capacitor nonlinearity. The capless operation is confirmed in the datasheet's General Description and Section 8.2.4, and is enabled by the HP_CFG register (0x23) and supported across all supported load impedances including 16 Ω.

What sample rates does the DA7210-00UC2 support, and how is clocking managed?

The DA7210-00UC2 supports sample rates from 8 kHz to 96 kHz in both master and slave modes. Clocking is managed via an on-chip PLL that accepts common external clocks - including 12, 13, 24, 26, or 27 MHz - and generates precise audio clocks for any supported rate. The PLL also enables sample rate matching (SRM) for asynchronous sources. Configuration is performed through registers PLL_DIV1–PLL_DIV3 (0x29–0x2B) and PLL (0x2C), with lookup tables provided in datasheet Tables 32–34 and 37–38 for exact settings.

How does the DA7210-00UC2 handle microphone input and noise reduction?

The DA7210-00UC2 provides two differential microphone inputs (MIC1P/N, MIC2P/N) with programmable bias voltage and variable-gain preamplifiers. It includes dedicated voice-mode high-pass filtering (8 kHz or 16 kHz cutoff), automatic level control (ALC) with adjustable attack/decay, and a hardware-accelerated wind noise suppression algorithm executed in its ASSP DSP engine. These features are configured via registers MIC_L (0x07), MIC_R (0x08), and ALC_NOIS (0x85), and are validated in Sections 8.1.2 and 8.6 of the datasheet for real-world portable use cases.

What package type and dimensions does the DA7210-00UC2 use?

The DA7210-00UC2 is packaged in a 49-bump wafer-level chip-scale package (WL-CSP) with 0.4 mm ball pitch and overall dimensions of 2.1 mm × 2.1 mm × 0.5 mm (max). This package is specified in Section 11 of the datasheet and illustrated in Figure 51. It supports standard reflow soldering per J-STD-020 and is designed for high-density portable PCB layouts where space and thermal performance are critical constraints.
