ADAU1761BCPZ-R7

ADAU1761 is a low power, stereo audio codec with integrated digital audio processing that supports stereo 48KHz record and playback at 14mW from a 1.8V analogue supply. The processor allows system designers to compensate for the real-world limitations of microphones, speakers, amplifiers, and listening environments, resulting in a dramatic improvement in the perceived audio quality through equalization, multiband compression, limiting, and third-party branded algorithms. It includes five high power output drivers (two differential and three single-ended), supporting stereo headphones, an earpiece, or other output transducer. AC-coupled or capless configurations are supported. Individual fine level controls are supported on all analogue outputs. The output mixer stage allows for flexible routing of audio. Typical applications are smartphones/multimedia phones, digital still cameras/digital video cameras, portable media players/portable audio players, phone accessories products.

• Output mixer stage allows for flexible routing of audio, GPIO pins for digital controls and outputs
• Fully programmable with SigmaStudio graphical tool, 1 mono headphone output driver
• Flexible analogue input/output mixers, stereo digital microphone input
• Analog automatic level control (ALC), microphone bias reference voltage
• Digital audio serial data I/O: stereo and time-division multiplexing (TDM) modes
• Software-controllable clickless mute, software power-down
• Common-mode rejection ratio is 65dB typ (100mV rms, 1KHz)
• 32-lead frame chip scale package [LFCSP-VQ]
• Temperature rating range from −40°C to +85°C
