ADC3910S025IRSMR

Analog To Digital Converters (ADC) Overview

The ADC3910S025IRSMR is a single-channel, 10-bit analog-to-digital converter from the Texas Instruments ADC3910 family. It supports a sampling rate of 25MSPS with a latency of only one clock cycle in low-latency mode. The device operates on a single 1.8V analog supply and an IOVDD ranging from 1.8V to 3.3V. At 25MSPS, it consumes approximately 41mW of power. Key performance metrics at fIN = 5MHz include a signal-to-noise ratio (SNR) of 61dBFS and a spur-free dynamic range (SFDR) of 65dBc. It features buffered differential or single-ended inputs with a 150MHz bandwidth and integrates dual digital comparators for event-triggered interrupts.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRSMR' against the manufacturer's official ordering information to confirm package type, temperature grade, and reel specifications. Ensure compatibility with the required input voltage levels and interface configuration before finalizing procurement. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin functions that may affect integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel architecture is sufficient, as opposed to the dual-channel ADC3910Dx variants. The '025' designation indicates a fixed 25MSPS sampling rate; choose higher speed grades if greater throughput is required. Confirm that the 10-bit resolution meets the system's dynamic range needs, considering the available 8-bit alternatives within the same family for lower power consumption.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC3910 series, which includes pin-compatible single and dual channel variants with resolutions of 8-bit and 10-bit. The series offers multiple speed grades (25, 65, and 125 MSPS). The ADC3910S025 specifically targets single-channel applications requiring low latency and power efficiency, sharing the same 32-pin VQFN package and core functionality as its dual-channel counterparts.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible replacements within the same family include the ADC3910S065 and ADC3910S125 for higher sampling rates, or the ADC3910Dx series for dual-channel requirements. Verify that the replacement part number matches the required speed grade and channel count. Ensure that any change in speed grade does not exceed the thermal limits of the existing PCB layout.

Analog To Digital Converters (ADC) FAQ

What is the default output interface for the ADC3910S025?

The default output interface for the single-channel ADC3910Sx devices is Single Data Rate (SDR) CMOS.

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

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

Can the ADC3910S025 operate with an external reference?

Yes, the device supports both internal and external voltage references. An external 1.2V reference can be applied to the VREF pin.
