Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRSMR' against the manufacturer's official datasheet to confirm pinout compatibility and temperature range specifications. Ensure that the required supply voltage levels match the device's 1.8V analog and optional 3.3V digital I/O requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model over dual-channel variants when only one conversion channel is needed to optimize board space and power. Consider the ADC3908D065 if a second channel is anticipated, as it shares similar performance characteristics but offers two independent inputs within the same package footprint.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC3908 series, which includes both single-channel (S) and dual-channel (D) variants available at 25, 65, and 125 MSPS speeds. The series is designed for applications demanding high linearity and low power, featuring a compact 4mm x 4mm VQFN package suitable for dense PCB layouts.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADC3908S025 (25 MSPS) and ADC3908S125 (125 MSPS), provided the system timing constraints allow for different sampling rates. Dual-channel equivalents like the ADC3908D065 are pin-compatible but utilize an unused channel.
