AD1954YSRL

Digital To Analog Converters Overview

The AD1954YSRL is a 24-bit, triple-channel audio digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It utilizes Delta-Sigma architecture and features a serial interface for data input. The device provides three independent output channels with bipolar voltage outputs, designed for high-fidelity audio applications. It operates on a single 5V supply and is housed in a 48-lead LQFP package measuring 7x7x1.4mm. Key electrical specifications include a maximum sampling rate of 48ksps, a full-scale error of ±8% FSR, and a settling time of 112µs. The component supports external voltage references and functions within an operating temperature range of -40°C to +105°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'YSRL' against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for the 48-LQFP form factor. Cross-reference lead times and availability through authorized distributors as stock levels fluctuate. Confirm that the external reference requirements align with system design constraints.

Digital To Analog Converters Selection Notes

Select this component when a triple-channel, 24-bit DAC is required for audio applications. Compare against other ADI audio DACs based on channel count, resolution, and interface compatibility. Consider the 48ksps sampling rate limit and bipolar output nature. Verify power supply requirements (single 5V) and thermal performance within the specified -40°C to +105°C range for the target environment.

Digital To Analog Converters Part Context

The AD1954YSRL belongs to the AD1954 series of audio DACs from Analog Devices. This series is characterized by its use of SigmaDSP technology and high-resolution audio conversion capabilities. The 'YSRL' suffix typically denotes a specific packaging variant, such as a reel quantity or lead-free status, distinct from other variants like YSTZ. It is part of Analog Devices' portfolio for precision data acquisition and audio processing.

Digital To Analog Converters Replacement Considerations

Direct replacements may include other AD1954 variants (e.g., AD1954YSTZ) if pinout and functionality are identical. Check for updated revisions or alternative packages from Analog Devices. Ensure any substitute maintains the 24-bit resolution, triple-channel configuration, and 48-LQFP footprint.
