ADC3663IRSBR

Analog To Digital Converters (ADC) Overview

The ADC3663IRSBR is a dual-channel, 16-bit analog-to-digital converter from Texas Instruments operating at sampling rates up to 65 MSPS. It features a noise spectral density of -158 dBFS/Hz and delivers an SNR of 81.9 dBFS with an SFDR of 92 dBc at fIN = 10 MHz. The device supports external or internal voltage references and utilizes a serial LVDS interface. Power consumption reaches 94 mW per channel at maximum speed. It operates within an industrial temperature range of –40°C to +105°C and is housed in a 40-pin WQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRSBR corresponds to the reel packaging format when ordering. Confirm that the required sampling rate and reference configuration match the ADC3663 specifications. Ensure compatibility with the 40-WQFN footprint during PCB layout planning. Check for updated documentation revisions to confirm current manufacturing status.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3663 when 16-bit resolution and 65 MSPS throughput are required. Compare power consumption against lower-speed variants like the ADC3661 if system constraints demand reduced energy usage. Evaluate the need for the integrated digital downconverter based on baseband processing requirements. Verify that the input bandwidth and dynamic range meet the specific signal integrity needs of the application.

Analog To Digital Converters (ADC) Part Context

The ADC3663 belongs to the ADC366x family, which includes the ADC3661 (10 MSPS) and ADC3662 (25 MSPS). These devices share pin compatibility and architectural features but differ in maximum sampling rates. The family is designed for low-noise applications requiring high linearity and dynamic range in a compact form factor.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3661 and ADC3662 are pin-compatible alternatives within the same family offering lower sampling rates. For higher speed requirements, the 14-bit ADC3664 provides 125 MSPS operation. Ensure that any substitute part meets the specific noise and power dissipation requirements of the design.
