ADC3910S025IRSMT

Analog To Digital Converters (ADC) Overview

The ADC3910S025IRSMT is a single-channel, 10-bit analog-to-digital converter from the Texas Instruments ADC3910 family. It operates at a sampling rate of 25 MSPS with a latency of one clock cycle in low-latency mode. The device features a 150 MHz input bandwidth and accepts buffered differential or single-ended inputs with a full-scale range of 1.9 Vpp (differential) or 0.95 Vpp (single-ended). Power consumption is 41 mW at 25 MSPS using a single 1.8V AVDD supply and optional 3.3V IOVDD. It includes integrated digital comparators, a statistics engine, and supports DDR, SDR, or serial CMOS interfaces within a 32-pin VQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRSMT corresponds to the industrial temperature grade (-40°C to +105°C) and the 32-VQFN package configuration. Confirm that the ordering code matches the single-channel variant (S) rather than the dual-channel (D) version. Ensure compatibility with the required 1.8V analog supply and 1.8V to 3.3V digital I/O voltage levels during procurement validation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel architecture is sufficient, as it offers lower power dissipation compared to the dual-channel counterpart. Consider the 25 MSPS speed grade if system timing allows for reduced processing load. Verify that the 10-bit resolution meets dynamic range requirements, noting the typical SNR of approximately 60 dBFS. Ensure the design accommodates the 1.25V common-mode voltage requirement for analog inputs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC3910 family, which also includes 8-bit variants and higher speed grades (65 MSPS and 125 MSPS). The 'S' designation indicates a single-channel device, while 'D' denotes dual-channel. All members share pin compatibility and core architectural features, allowing for scalable design transitions based on channel count and throughput needs.

Analog To Digital Converters (ADC) FAQ

What is the default output interface for the single-channel ADC3910Sx?

The default interface for the single-channel device in low-latency mode is Single Data Rate (SDR) CMOS.

How does the device handle analog input common-mode voltage?

The device provides an internal VCM output pin that generates a 1.25V common-mode voltage, which must be used to bias the analog inputs.

Can the ADC3910S025 operate without an external voltage reference?

Yes, the device supports an internal 1.2V reference by connecting the VREF pin to ground, though an external reference can also be used for potentially better performance.
