ADC3908S125IRSMR

Analog To Digital Converters (ADC) Overview

The ADC3908S125IRSMR is a single-channel, 8-bit analog-to-digital converter from the Texas Instruments ADC3908 series. It operates at a maximum sampling rate of 125 MSPS with a power consumption of 61 mW. The device features a 150 MHz input bandwidth and integrates an internal 1.2 V reference. It utilizes parallel DDR or SDR CMOS interfaces compatible with 1.8 V or 3.3 V I/O levels. Packaged in a 32-pin VQFN (4 mm x 4 mm) for surface mount installation, it supports an industrial temperature range of -40°C to +105°C.

Analog To Digital Converters (ADC) Feature Summary

• Single-channel architecture with 125 MSPS sampling speed
• Ultra-low power consumption of 61 mW at full speed
• Integrated 1.2 V internal voltage reference
• Configurable parallel DDR/SDR CMOS interface

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Wireless communication base stations
• Test and measurement instrumentation

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC3908 family, which includes dual-channel variants (ADC3908Dx) and other speed grades (25 MSPS, 65 MSPS). The 'S' suffix denotes the single-channel configuration, while '125' indicates the 125 MSPS performance tier. All members share the same 32-VQFN footprint and core architectural features.

Analog To Digital Converters (ADC) Replacement Considerations

For dual-channel requirements, consider the ADC3908D125 variant. For lower power applications, the ADC3908S025 (25 MSPS) or ADC3908S065 (65 MSPS) are pin-compatible alternatives within the same package.
