DA7217

Ultra-Low Power Stereo Codec

General Description

DA7217 is a high-performance, low-power audio codec optimized for use in headsets or wearable

devices. It has differential headphone outputs for use inside headset devices, offering excellent left to

right channel separation and common mode noise rejection. DA7217 also has a stereo DAC to

headphone output path and ultra-low power operating modes to support always-on audio detect

applications.

DA7217 contains two analog microphone input paths, or up to four digital microphone input paths, or

a combination of both. The other chip in this family, the DA7218, has single-ended headphone

outputs, and has been designed with headphone detect for use in accessories.

Key Features

■

High performance stereo DAC to headphone ■ Flexible digital mixing from all seven inputs to

playback path with 110 dB dynamic range

all six outputs with independent gain on each

mixer path

■

4 mW stereo playback power consumption

■

Ability to run the ADCs at a different sample

rate to the DACs on a single I²S interface

DAC digital filters with audio and voice mode

options, five-band equalizer and five

programmable biquad stages

Digital tone generator with built-in support for

DTMF

■

Dedicated low-latency digital sideband filter

with three programmable biquad stages

System controller for simplified, pop-free start-

up and shutdown

High performance microphone to ADC record

path with 105 dB dynamic range

Phase-locked loop with sample rate tracking

supporting MCLK frequencies from 2 MHz to

54 MHz

■

2.5 mW stereo record power consumption

ADC digital filters with audio and voice mode

options

■

Automatic tuning of on-chip reference

oscillator for clock-free operation in low-power

modes

■

500 µW always-on record mode with

automatic level detection

4-wire digital audio interface with support for

I²S, four-channel I²S, TDM and other audio

formats

2-wire I²C compatible control interface with

support for High Speed mode up to 3.4 MHz

Hybrid analog / digital automatic level control

to dynamically control the record level

Shutdown mode offering current consumption

during standby of 2.5 µA

Two low-noise microphone bias regulators

with programmable output voltage and ultra-

low power mode

■

24-bit data at up to 96 kHz sample rate

The headphone amplifier can be run directly

from the supply, thus eliminating the need for

charge pump capacitors

■

A high efficiency two-level, true-ground charge

pump for generating class-G headphone

supplies

Voice mode filtering up to 32 kHz

Applications

■

Hearables

■

Wireless and wired headsets

Wireless and wired headphones
