AD1852JRSZRL

Overview

The AD1852JRSZRL is a stereo, 24-bit, 192 kHz multibit sigma-delta digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates from a single 5 V supply and features differential analog outputs for optimal performance. The device supports sample rates including 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, and 192 kHz. Key electrical specifications include a signal-to-noise ratio of up to 117 dB (A-weighted mono at 48 kHz) and a dynamic range of 117 dB (A-weighted mono at 48 kHz). Total Harmonic Distortion plus Noise (THD+N) is specified at -102 dB in stereo mode. The component is housed in a 28-lead SSOP package.

Feature Summary

• Multibit Sigma-Delta Modulator: Provides perfect differential linearity restoration to reduce idle tones and noise floor.
• Flexible Serial Interface: Supports right-justified, left-justified, I2S-compatible, and DSP serial port modes with word lengths of 16, 18, 20, or 24 bits.
• Integrated Control Features: Includes on-chip clickless volume control, hardware/software controllable mute, and digital de-emphasis processing.
• Master Clock Autodivide: Automatically detects and divides master clock frequencies (256x to 1024x fS) to support various interpolation modes.

Applications

• High-end DVD players
• Home theater systems
• Digital mixing consoles
• Sampling musical keyboards
• Automotive audio systems

Procurement Notes

Verify the specific ordering suffix JRSZRL against the manufacturer's current datasheet to confirm package type (SSOP) and temperature grade (Commercial, 0°C to 70°C). Confirm RoHS compliance status as per the latest regulatory documentation. Ensure that the serial control interface requirements align with the host system's SPI capabilities.

Selection Notes

Select this component for applications requiring high-resolution audio playback up to 24-bit/192 kHz. Ensure the design accommodates a single 5 V power supply for both analog and digital domains. Verify that the host processor can support the required serial data formats (I2S, Left/Right Justified, or DSP mode) and provides the necessary master clock frequencies.

Part Context

The AD1852 is part of Analog Devices' high-performance audio DAC family. It is designed as a complete single-chip stereo digital audio playback system, integrating multibit sigma-delta modulation, digital interpolation filters, and analog output drive circuitry. The JRSZRL designation indicates the commercial temperature range and SSOP packaging variant.
