ADC3910S125IRSMT

Analog To Digital Converters (ADC) Overview

The ADC3910S125IRSMT is a single-channel, 10-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 125MSPS with a latency of only one clock cycle in low-latency mode. The device operates on a single 1.8V supply and features buffered differential or single-ended inputs with a 150MHz bandwidth. Power consumption scales with the sampling rate, reaching 80mW at 125MSPS. It includes integrated digital comparators, an optional on-chip digital filter, and statistics engine. The component is housed in a 32-pin VQFN package measuring 4mm x 4mm and supports industrial temperatures from -40°C to +105°C.

Analog To Digital Converters (ADC) Feature Summary

• Ultra-low power consumption that scales dynamically with the selected sampling rate
• Integrated digital signal processing including a digital down-converter and statistics engine
• Dual digital window comparators for event-triggered interrupts and analog monitoring
• Flexible data output interfaces supporting parallel SDR/DDR and serial CMOS modes

Analog To Digital Converters (ADC) Applications

• Radio receiver systems
• LiDAR applications
• Low latency control loops
• Laser scanners
• Global positioning systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix 'RSMT' against the manufacturer's official documentation to confirm the specific reel quantity and tape-and-reel packaging configuration. Ensure the voltage reference selection matches the system requirements, as the device supports both internal and external references. Confirm the interface timing aligns with the target digital logic levels.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a single channel with high-speed conversion is required. The '125' suffix indicates the maximum sampling rate capability. Consider the ADC3910D125 if dual-channel operation is needed, as it shares pin compatibility. Evaluate the power budget carefully, as consumption varies significantly between 25MSPS and 125MSPS operating points.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC3910 family, which includes variants with different resolutions (8-bit and 10-bit) and speed grades (25MSPS, 65MSPS, 125MSPS). The family is designed for pin-to-pin compatibility across these variations. The single-channel version complements the dual-channel models, offering a compact solution for space-constrained designs requiring high dynamic performance.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3910D125 serves as a dual-channel alternative within the same family. Other speed grades like the ADC3910S065 or ADC3910S025 are compatible substitutes if lower sampling rates suffice. Verify register compatibility and interface timing when migrating between different speed grades in the series.
