AD1836AASZ

The AD1836AASZ from Analog Devices is a versatile multichannel audio CODEC designed for various audio applications. This integrated circuit offers 24-bit resolution and supports a 96 kHz conversion rate, ensuring high-fidelity audio processing. It integrates two analog-to-digital converters (ADCs) and three digital-to-analog converters (DACs), making it suitable for complex audio signal paths.

Operating within a voltage range of 4.75V to 5.25V, the AD1836AASZ features a serial data interface, specifically SPI (4-wire), for flexible control and data transfer. It is housed in a 52-QFP package, designed for surface mount applications, and can operate across a wide temperature range from -40°C to 85°C. The device also boasts impressive audio performance metrics, including a THD + Noise of -92 dB for ADCs and -95 dB for DACs, and SNR values of 105 dB for ADCs and 108 dB for DACs. Its compact dimensions of 10.2 mm length, 10.2 mm width, and 2.45 mm height make it suitable for space-constrained designs.

Key features include multibit Σ-Δ modulators, on-chip volume control with an auto-ramp function, and a programmable gain amplifier for ADC input. The flexible serial data port supports various modes including right-justified, left-justified, I2S compatible, and DSP serial port modes. It also includes a power-down mode for energy efficiency.
