Overview
Description
The DA7212 is a high-performance, low-power audio codec with an enhanced hybrid Automatic Level Control (ALC) and a powerful speaker driver targeting wearable, portable, and embedded applications. It operates from a single supply and has an internal LDO that can be used to optimize power consumption.
The DA7212 audio codec has exceptionally low always-on power consumption (650µW) which can extend the battery life of portable devices – including wearable devices - in an "always-on" mode enabling constant tracking and instant recognition of voice commands.
It integrates an enhanced hybrid ALC that offers faster reaction times and finer gain resolution to maintain a consistent audio quality level when recording.
Features
- High-performance 24-bit audio codec in 7.5mm2 footprint
- Ultra-low power consumption. Stereo Playback: 6.9mW, Stereo Record: 2.0mW at 1.8V
- Supports up to four analog microphones with two switchable low-noise microphone bias outputs
- Digital microphone interface supporting single-channel or dual-channel options
- Stereo auxiliary input channel
- Flexible analog and digital mixing paths
- DSP for ALC, 5-band EQ, noise gate, beep generator
- System controller for pop/click-free operation and easy setup
- Bidirectional I2S with sample-rate tracking
- Mono lineout/mini speaker driver: 1.2W at 5V, THD<10%, R = 8Ω
- Integrated PLL supports common audio sample rates between 8kHz - 96kHz from 2MHz - 54MHz reference clock
- Optimized ball-out conducive for low-cost PCB manufacturing
