Overview

The Texas Instruments ADC3683-SP is a radiation-hardness-assured, dual-channel, 18-bit analog-to-digital converter (ADC) supporting sampling rates from 1 to 65 MSPS. It features low latency, low noise with a spectral density of -160 dBFS/Hz, and ultra-low power consumption of 84 mW/ch at 65 MSPS. The device includes an optional digital down converter (DDC) with decimation factors of 2, 4, 8, 16, and 32, and utilizes a serial LVDS interface. It operates within an ambient temperature range of -55°C to 105°C and is housed in a 64-pin Ceramic Flat Pack (HBP) package.

Feature Summary

• Radiation hardness assured with QML-V screening, 300krad TID tolerance, and SEL immunity up to 75 MeV-cm2/mg
• Integrated digital down converter (DDC) supporting real or complex decimation by 2, 4, 8, 16, and 32
• Low latency architecture providing 1 clock cycle delay in 1-wire mode and 2 clock cycles in 2-wire mode
• Serial LVDS (SLVDS) interface available in 2-, 1-, and 1/2-wire configurations to minimize digital interconnects

Applications

• Optical imaging payload
• Radar imaging payload
• Satellite communication payloads

Procurement Notes

Verify the specific ordering suffix and grade requirements for your mission profile. Confirm that the QML-V screening and radiation performance metrics align with your system's environmental constraints. Ensure compatibility with the 64-pin CFP package dimensions and thermal management requirements before finalizing procurement specifications.

Selection Notes

Select this component when high-speed, high-resolution data acquisition is required in radiation-intensive environments. Consider the integrated DDC if reducing downstream data rates and system power consumption is a priority. Evaluate the SLVDS interface options based on trace count limitations and signal integrity requirements in your PCB layout.
