The TAA5242 is from a scalable family of devices. As part of the extended family of devices, the TAA5242 consists of a high-performance, low-power, flexible, mono/stereo, audio analog-to-digital converter (ADC). This device is intended for applications such as ruggedized communication equipment, IP network camera, Professional Audio and multimedia applications. The high dynamic range of this device enables far-field audio recording with high fidelity. This device integrates a host of features that reduce cost, board space, and power consumption in space-constrained system designs. Package, performance, and compatible configuration registers across extended family make this device well suited for scalable system designs.

The TAA5242 consists of the following blocks:

• 2-channel, multibit, high-performance delta-sigma (ΔΣ) ADCs
• Configurable single-ended or differential audio inputs with 2Vrms signal swing
• Low-noise microphone bias output
• Decimation filters with linear-phase
• High-pass filter (HPF)
• 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

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.
