ADS5541IPAPR

Analog To Digital Converters (ADC) Overview

The ADS5541IPAPR is a single-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a pipeline architecture and supports a maximum sampling rate of 105 MSPS. The device features a differential analog input with an internal reference. Electrical specifications include a signal-to-noise ratio (SNR) of 73.6 dB, an effective number of bits (ENOB) of 11.4 bits, and a spurious-free dynamic range (SFDR) of 86 dB. It operates on a 3.3 V analog supply and a 3 V to 3.6 V digital supply, consuming approximately 611 mW to 710 mW of power. The component is housed in a 64-lead HTQFP package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when sourcing this part number. Confirm that the HTQFP-64 package dimensions match the target PCB footprint. Ensure the design accommodates the required 3.3 V analog and 3 V to 3.6 V digital supply rails. Check for moisture sensitivity level requirements during storage and handling procedures.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS5541IPAPR when a 105 MSPS sampling rate and 14-bit resolution are required. Compare SNR and SFDR metrics against alternative ADCs if dynamic range is critical. Consider the parallel interface complexity versus serial alternatives like SPI. Evaluate power dissipation limits relative to the thermal management capabilities of the enclosure.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS554x family of high-speed ADCs from Texas Instruments. It shares architectural similarities with the ADS5542 but offers a higher sampling rate of 105 MSPS compared to the 80 MSPS variant. The IPAPR designation specifies the surface-mount HTQFP-64 package with reel packaging for automated assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5542IPAPR serves as a lower-speed alternative within the same family. Verify pin compatibility and software register settings when substituting between these models. Ensure the reduced sampling rate of the replacement meets the system bandwidth requirements.
