ADC3641IRSBR

Analog To Digital Converters (ADC) Overview

The ADC3641IRSBR is a dual-channel, 14-bit analog-to-digital converter with a maximum sampling rate of 10 MSPS. It operates on a single 1.8-V supply and features an ultra-low noise floor of –155 dBFS/Hz. The device offers configurable power consumption ranging from 29 mW/ch at 10 MSPS to 72 mW/ch at 65 MSPS. It supports both DDR and serial CMOS digital interfaces and includes an optional on-chip digital filter for decimation by 2, 4, 8, 16, or 32. The component provides a latency of one clock cycle and maintains integral nonlinearity within ±0.6 LSB and differential nonlinearity within ±0.2 LSB.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRSBR against the manufacturer's package option addendum to confirm the 40-VQFN (RSB) package configuration. Ensure the ordering information matches the required industrial temperature range specifications. Cross-reference the datasheet revision history to confirm the current documentation status before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 10 MSPS sampling rate is sufficient for the application requirements. Compare performance metrics against the ADC3642 and ADC3643 variants if higher throughput is needed. Evaluate the power dissipation characteristics relative to the thermal resistance values provided in the datasheet to ensure adequate heat management within the system design constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC364x family of low-noise, high-speed analog-to-digital converters. The family includes the ADC3642 operating at 25 MSPS and the ADC3643 operating at 65 MSPS. All devices share pin compatibility and similar architectural features, allowing for scalable design implementations across different speed requirements while maintaining consistent interface and power management characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3642 and ADC3643 are pin-compatible alternatives within the same family. Verify that the increased sampling rates of these substitutes do not exceed the system's power budget or timing constraints. Confirm that the specific suffix variations match the required package type and temperature rating.
