ADC3561IRSBR

Analog To Digital Converters (ADC) Overview

The ADC3561IRSBR is a 16-bit, 10-MSPS analog-to-digital converter from the Texas Instruments ADC356x family. It operates with a 1.8-V analog supply and features a serial LVDS interface. The device delivers a noise spectral density of –150 dBFS/Hz and an SNR of 82.0 dBFS at 10 MSPS. Power consumption is 77 mW typical at 10 MSPS. It supports external or internal voltage references and includes on-chip dual-band digital filters for decimation by 2, 4, 8, 16, or 32. The component is housed in a 40-WQFN (5 mm × 5 mm) package and functions within an industrial temperature range of –40°C to +105°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRSBR against the manufacturer's current orderable addendum to confirm package type and temperature grade. Ensure the ordering information matches the exact revision level required for your design. Cross-reference the datasheet SBAS990B for any recent updates regarding pin definitions or electrical characteristics before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3561 when a maximum sampling rate of 10 MSPS is sufficient for the application. Compare performance metrics such as SNR and power dissipation against the higher-speed ADC3562 and ADC3563 variants if faster throughput is required. Consider the available decimation options and the specific requirements for reference voltage configuration when evaluating this part against other members of the ADC356x family.

Analog To Digital Converters (ADC) Part Context

The ADC3561 is part of the broader ADC356x family, which also includes the ADC3562 and ADC3563. These devices share a common 40-pin WQFN package and pinout but differ in maximum sampling rates and speed grades. The family offers pin-to-pin compatibility with the ADC358x series, providing flexibility for designs requiring different resolutions or performance levels without altering the PCB layout.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3562 and ADC3563 are direct pin-compatible replacements within the same family, offering higher sampling rates of 25 MSPS and 65 MSPS respectively. Designers should verify that the increased speed and potential changes in power consumption align with system requirements when substituting these parts.
