Overview
The AD1853JRSRL 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 accepts 16-, 18-, 20-, or 24-bit data across sample rates of 32 kHz to 192 kHz. The device integrates a high-performance digital interpolation filter, a multibit sigma-delta modulator with perfect differential linearity restoration, and a continuous-time current-output analog section. Key electrical specifications include a signal-to-noise ratio of 120 dB (A-weighted mono at 48 kHz) and dynamic range of 119 dB (A-weighted mono). It features on-chip clickless volume control, hardware/software mute, and digital de-emphasis filters for 32, 44.1, and 48 kHz rates.
Feature Summary
- Multibit Sigma-Delta Modulator: Utilizes '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 via SPI control.
- High Performance Audio: Achieves 120 dB SNR (Mono, A-weighted) and -107 dB THD+N (Mono) at 48 kHz.
- Integrated Control Features: Includes on-chip clickless stereo attenuator, mute capability, and digital de-emphasis processing.
Applications
- DVD and CD audio playback systems
- Home theater systems
- Automotive audio systems
- Sampling musical keyboards
- Digital mixing consoles
Procurement Notes
Verify the obsolete status of the AD1853 family before procurement planning. Confirm that the RS-28 package and RL suffix denote the 28-lead SSOP form factor on 13-inch reels. Ensure compatibility with existing system designs as this component may no longer be in active production.
Selection Notes
Select the AD1853JRSRL for applications requiring high-resolution stereo DAC performance up to 192 kHz. Ensure the design supports a single +5 V power supply and accommodates the required serial interface timing. Verify that the 28-lead SSOP package fits the PCB layout constraints and thermal requirements for the 0°C to +70°C operating range.
Part Context
The AD1853JRSRL belongs to the AD1853 product family, which is a complete high-performance single-chip stereo digital audio playback system. It is designed to meet DVD audio specifications and offers glueless interconnection to various ADCs, DSP chips, and sample rate converters through its flexible serial data input port.
Replacement Considerations
The AD1853 family is marked as obsolete. No specific public substitute part numbers are provided in the source material. Designers should consult Analog Devices for current replacement recommendations or evaluate alternative high-resolution stereo DACs with similar pinouts and performance characteristics.
