ADC3682IRSBR

Analog To Digital Converters (ADC) Overview

The ADC3682IRSBR is a dual-channel, 18-bit analog-to-digital converter from the Texas Instruments ADC368x family. It operates at a sampling rate of 25 MSPS with a differential serial LVDS interface. The device features a noise spectral density of -156.1 dBFS/Hz and an SNR of 84.7 dBFS at 1.1 MHz input frequency. DC specifications include ±0.7 LSB DNL and ±7 LSB INL. Power consumption is typically 119 mW at 25 MSPS using an external reference. It utilizes a 40-pin VQFN package (5 mm x 5 mm) and supports an industrial temperature range from -40°C to +105°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to ensure correct packaging and tape-and-reel quantities. Confirm that the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision history to ensure compatibility with existing design documentation and application notes.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3682IRSBR when a balance between high resolution and moderate speed is required. Compare it against the ADC3681 for lower power applications or the ADC3683 for higher bandwidth needs. Ensure the system clock jitter requirements align with the specified aperture jitter limits. Verify that the available supply voltage ranges match the recommended operating conditions for both analog and digital domains.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC368x series, which includes the ADC3681 and ADC3683. All members share pin-to-pin compatibility and identical package dimensions. The series is designed for low-noise, ultra-low-power applications requiring 18-bit precision. The ADC3682 specifically targets the 25 MSPS segment of this family.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3681IRSBR and ADC3683IRSBR are pin-compatible alternatives within the same family. Selection depends on whether a lower sampling rate of 10 MSPS or a higher rate of 65 MSPS better suits the system requirements while maintaining the same 18-bit resolution and interface.
