概述

Description

ADAU1777BCBZRL is an Analog Devices multi-channel audio analog-to-digital converter (ADC). It converts incoming analog audio into digital data for downstream DSPs or microcontrollers. Key aspects:
- High-resolution audio: up to 24-bit conversion.
- Sampling rates: up to around 96 kHz (suitable for many consumer/pro audio apps).
- Inputs: differential audio channels with programmable gain.
- Digital interface: streams data via a standard audio bus (I2S/PCM); serial control port to configure registers (gain, routing, sampling rate, etc.).
- Power management and typical low-noise performance for audio capture.
- Applications: microphones, line-input capture, portable/embedded audio systems, automotive or consumer audio gear.
The suffix BCBZRL denotes the specific device variant and packaging/temperature grade (e.g., a particular LFCSP package). For exact pinout, voltages, current consumption, and the register map, refer to the ADAU1777 datasheet and ordering guide.

Features

Key features of ADAU1777BCBZRL (Analog Devices):
- 2-channel, 24-bit sigma-delta analog-to-digital converter (ADC)
- Supports up to common audio sample rates (typical up to 96 kHz)
- I2C-compatible control interface (standards via software/SigmaStudio)
- Digital audio interfaces: I2S, Left-Justified, PCM
- Differential microphone inputs with programmable gain
- On-chip reference and microphone biasing
- Low-noise, low-distortion analog performance
- Power-management options for reduced consumption
- Available in the BCBZRL package (compact package)
Note: exact electrical specs (max sample rate, gains, voltage ranges) are best verified on the official datasheet for the specific lot.

Package

ADAU1777BCBZRL uses a 28‑lead LFCSP (Lead Frame Chip Scale Package), about 3x3 mm, RoHS‑compliant (suffix RL indicates RoHS).
