ADC3908D125IRSMT

Analog To Digital Converters (ADC) Overview

The ADC3908D125IRSMT is a dual-channel, 8-bit analog-to-digital converter from Texas Instruments. It supports sampling rates up to 125 MSPS with an ultra-low latency of only one clock cycle. The device operates on a single 1.8V supply and features parallel DDR CMOS interface outputs. Power consumption is 90 mW at maximum speed, scaling down to 56 mW at 25 MSPS. It includes an internal reference, buffered differential or single-ended inputs, and a 150 MHz input bandwidth. The component is housed in a compact 32-pin VQFN package (4mm x 4mm) and functions within an industrial temperature range of -40°C to +105°C.

Analog To Digital Converters (ADC) Feature Summary

• Ultra-low latency architecture providing a delay of only one clock cycle for high-speed control loops
• Integrated input buffers supporting both differential and single-ended signal configurations
• Configurable digital interface allowing operation with either 1.8V or optional 3.3V IO levels
• Pin-controlled configuration for default operating conditions without requiring serial communication

Analog To Digital Converters (ADC) Applications

• Low latency control loops
• Laser scanners
• Displacement sensors
• Detection equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRSMT corresponds to the required tape-and-reel packaging format and ensure the ordering code matches the exact pinout and thermal pad requirements specified in the manufacturer's official documentation before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model when system design requires minimal signal processing delay alongside low power consumption at high speeds. Ensure the host processor supports parallel DDR data capture and that the 1.8V logic level compatibility aligns with the system's digital interface standards.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC3908 family, which offers pin-compatible variants with different resolution and speed grades. It shares the same physical footprint as other members of the series, facilitating design flexibility across product lines requiring varying performance levels.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include ADC3908D065 and ADC3908D025 for lower speed applications. For higher resolution needs, consider the ADC3910D125, though it utilizes SPI control rather than pin control.
