ADC3643IRSBT

Analog To Digital Converters (ADC) Overview

The ADC3643IRSBT is a dual-channel, 14-bit analog-to-digital converter from Texas Instruments operating at sampling rates up to 65 MSPS. It features ultra-low power consumption scaling from 29 mW/ch at 10 MSPS to 72 mW/ch at 65 MSPS. The device delivers a noise spectral density of –155 dBFS/Hz and achieves an SNR of 79.0 dBFS at 1 MHz input frequency. It supports DDR and serial CMOS interfaces with a latency of one clock cycle. Powered by a single 1.8-V supply, it operates within an industrial temperature range of –40°C to +105°C and includes an optional on-chip digital filter.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's package option addendum to confirm the exact reel or tube quantity and tape specifications. Ensure the component matches the required industrial temperature grade and voltage reference configuration before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when high-speed conversion up to 65 MSPS is required alongside strict power constraints. Compare performance metrics such as SNR and SFDR against lower speed variants like the ADC3641 or ADC3642 if system bandwidth allows. Consider the available interface modes and internal versus external reference requirements for optimal design integration.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC364x family of low-noise, low-power dual-channel ADCs. It shares pin compatibility with other members of the series, differing primarily in maximum sampling rates. The family is designed for applications requiring high precision and low power consumption across extended industrial temperature ranges.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the ADC3641 (10 MSPS) and ADC3642 (25 MSPS). Verify that the reduced sampling rates of these substitutes meet the specific bandwidth requirements of the target application.
