ADC3642IRSBT

Analog To Digital Converters (ADC) Overview

The ADC3642IRSBT is a dual-channel, 14-bit analog-to-digital converter from the Texas Instruments ADC364x family. It supports sampling rates up to 25 MSPS with an ultra-low noise floor of -155 dBFS/Hz and optimized power consumption scaling down to 29 mW per channel at lower speeds. The device features a latency of one clock cycle, ensuring high-speed control loop performance. It operates on a single 1.8-V supply and includes an optional on-chip digital filter for decimation by 2, 4, 8, 16, or 32. The component utilizes DDR or Serial CMOS interfaces and is housed in a compact 40-pin VQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure that any custom configuration requirements align with the supported SPI register map. Confirm availability through authorized distribution channels as production status may vary. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin functions prior to final procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3642IRSBT when a 25 MSPS sampling rate meets system bandwidth requirements while maintaining low power constraints. Compare it against the ADC3641 (10 MSPS) and ADC3643 (65 MSPS) within the same family to optimize cost and performance. Consider the available DDR or Serial CMOS interface options based on PCB trace count limitations. Verify that the required decimation factors are supported by the internal digital filter for the target application.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC364x series, which includes the ADC3641, ADC3642, and ADC3643. These devices share a common pinout and feature set, differing primarily in their maximum sampling rates. The family is designed for low-noise, low-power applications requiring high dynamic range. All members support industrial temperature ranges and offer flexible interface options.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3641 and ADC3643 are pin-compatible alternatives within the same family. Select the ADC3641 if a lower sampling rate of 10 MSPS is sufficient to reduce power consumption. Choose the ADC3643 if a higher sampling rate of 65 MSPS is required without changing the board layout.
