ADC3663IRSBT

Analog To Digital Converters (ADC) Overview

The ADC3663IRSBT is a dual-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports sampling rates up to 65 MSPS with an input bandwidth of 900 MHz. The device operates on a single 1.8 V supply for both analog and digital domains, consuming 94 mW per channel at maximum speed. Key electrical specifications include a signal-to-noise ratio (SNR) of 81.9 dBFS, a spurious-free dynamic range (SFDR) of 92 dBc, and an effective number of bits (ENOB) of 13.3 bits. It features serial LVDS output interfaces and is housed in a 40-pin WQFN package rated for operation between -40°C and +105°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRSBT' against the manufacturer's official datasheet to confirm the temperature grade, package type, and tape-and-reel quantity. Ensure that the ordering information matches the exact revision level required for your design. Cross-reference the component marking with the official identification guide to prevent counterfeit substitution during procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a balance of high resolution and moderate speed is required for multi-channel applications. Compare power consumption across the ADC366x family if lower sampling rates suffice, as power scales with speed. Verify that the 1.8 V supply voltage aligns with the system power architecture and that the serial LVDS interface is compatible with the downstream FPGA or processor logic levels.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC366x family of low-power, high-speed SAR ADCs from Texas Instruments. The family includes variants such as the ADC3661 (10 MSPS), ADC3662 (25 MSPS), and ADC3664 (125 MSPS). These devices share pin compatibility and architectural similarities, allowing for design flexibility within the same product line while offering different speed and resolution options.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same series include the ADC3661, ADC3662, and ADC3664. Verify that the substitute part meets the specific sampling rate and SNR requirements of the application. Check for any differences in reference voltage configurations or interface timing characteristics before finalizing the replacement.
