Renesas DA7210-00UC6

Overview

DA7210-00UC6 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 DA7210-00UC6 datasheet, DA7210-00UC6 pinout, DA7210-00UC6 application, or DA7210-00UC6 equivalent, key selection considerations include its WL-CSP-49 package, Class-G capless headphone output delivering 2×58 mW into 16 Ω, multi-slot I²S/PCM interface supporting 8–96 kHz sample rates, and integrated DSP engine for wind noise suppression and 3D sound processing.

Technical Context

The DA7210-00UC6 implements a dual-path delta-sigma architecture: stereo ADCs with configurable high-pass filtering and ALC (attack/decay programmable), and stereo DACs with soft mute and digital high-pass filtering. Its PLL supports flexible clocking - including 32 kHz low-power mode and industry-standard 256×Fs - enabling precise sample rate matching across master/slave configurations.

Digital signal routing is managed via programmable mixers and multiplexers, allowing simultaneous use of stereo headphone, stereo line-out (differential or single-ended), and mono differential output. The on-chip ASSP DSP engine executes real-time acoustic filtering, 5-band EQ, and voice-mode high-pass filters (e.g., 8 kHz cutoff for recording) without host CPU intervention.

FAQ

What is the maximum output power of the DA7210-00UC6 headphone amplifier?

The DA7210-00UC6 headphone amplifier delivers 2×58 mW into a 16 Ω load with THD+N <1% at 1 kHz. This is achieved using a four-level Class-G charge pump that dynamically tracks the audio signal envelope, minimizing power loss compared to fixed-voltage Class-AB drivers. The DA7210-00UC6 achieves this performance while consuming only 2.5 mW in stereo playback mode.

Does the DA7210-00UC6 support differential microphone inputs?

Yes, the DA7210-00UC6 supports four fully differential microphone inputs (MIC1–MIC4), each with programmable bias voltage and variable-gain amplification. These inputs are internally routed to a shared ADC path with configurable high-pass filtering and automatic level control. The DA7210-00UC6's eight analogue input pins allow simultaneous connection of multiple mic types without external switching circuitry.

Can the DA7210-00UC6 operate from a single 1.8 V supply?

Yes, the DA7210-00UC6 is fully specified to operate from a single 1.8 V supply for both analogue (VDDA) and digital I/O (VDDIO) rails. Its internal charge pump generates boosted voltages for the headphone driver, eliminating the need for external higher-voltage supplies. This capability is confirmed in Section 5 (Recommended Operating Conditions) and Table 4 of the DA7210-00UC6 datasheet.

What sample rates does the DA7210-00UC6 support on its digital audio interface?

The DA7210-00UC6 supports sample rates from 8 kHz to 96 kHz across all digital audio interface modes (I²S, left/right-justified, DSP, TDM). It uses an on-chip PLL with sample rate matching to lock to non-integer multiples of MCLK, enabling robust operation with common system clocks such as 12 MHz, 13 MHz, 24 MHz, 26 MHz, 27 MHz, and 32.768 kHz. This flexibility is documented in Tables 32–38 of the DA7210-00UC6 datasheet.

Does the DA7210-00UC6 include hardware-based pop-and-click suppression?

Yes, the DA7210-00UC6 integrates dedicated hardware pop-and-click suppression circuitry that performs zero-crossing detection and controlled ramping during power-up, power-down, and volume transitions. This eliminates audible transients without requiring software intervention or additional external components. The feature is active by default and configurable via registers HP_CFG (0x23) and ZEROX (0x24) in the DA7210-00UC6 register map.
