The TAD5212 is from a scalable family of devices. As with the extended family of devices, the TAD5212 consists of a high-performance, low-power, flexible audio digital-to-analog converter (DAC) with extensive feature integration. This device is intended for automotive applications such as telematics control unit, hands-free in-vehicle communication, emergency call, and multimedia applications. This device integrates a host of features that reduce cost, board space, and power consumption in space-constrained automotive sub-system designs. Package, performance, and device-compatible configuration registers make this device well suited for scalable system designs.

The TAD5212 consists of the following blocks:

• Low-noise programmable microphone bias output
• 2-channel, multibit, high-performance delta-sigma (ΔΣ) DACs
• Configurable single-ended, differential or pseudo-differential audio outputs
• Over Current Diagnostics and Protection for MICBIAS and analog outputs
• Automatic gain controller (AGC)
• Advanced Thermal foldback and protection
• Advanced Battery guard and distortion limiter
• Programmable interpolation filters with linear-phase or low-latency filter
• Programmable channel gain, volume control, and biquad filters for each channel
• Programmable phase and gain calibration with fine resolution for each channel
• Programmable high-pass filter (HPF) and digital channel mixer
• Integrated low-jitter, phase-locked loop (PLL) supporting a wide range of system clocks
• Integrated digital and analog voltage regulators to support single-supply operation

Communication to the TAD5212 for configuring the control registers is supported using an I²C and SPI interface. The device supports a highly flexible audio serial interface [time-division multiplexing (TDM), I²S, or left-justified (LJ)] to transmit audio data seamlessly in the system across devices.
