Produktoversigt

The DA7217-EVAL from Dialog Semiconductor is an evaluation board for ultra-low power stereo codec DA7217. This 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. The 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 analogue microphone input paths or up to four digital microphone input paths or a combination of both. It features a flexible digital mixing from all seven inputs to all six outputs with independent gain on each mixer path, ability to run the ADCs at a different sample rate to the DACs on a single I2S interface, digital tone generator with built-in support for DTMF. It is used in hearables, wireless and wired headphones and headsets.
  • High performance stereo DAC to headphone playback path with 110dB dynamic range
  • High performance microphone to ADC record path with 105dB dynamic range
  • 4mW stereo playback and 2.5mW stereo record power consumption, 32KHz voice mode filtering
  • ADC digital filters with audio and voice mode options, 24bit data at up to 96KHz sample rate
  • System controller for simplified, pop-free startup and shutdown, 0.5mmpitch 32 ball WLCSP package
  • Phase-locked loop with sample rate tracking supporting MCLK frequencies from 2MHz to 54MHz
  • Automatic tuning of on-chip reference oscillator for clock-free operation in low-power modes
  • Headphone amplifier can be run directly from supply eliminating need for charge pump capacitors
  • 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 3.4MHz
