ADC12DL065CIVS

Analog To Digital Converters (ADC) Overview

The ADC12DL065CIVS is a dual-channel, 12-bit analog-to-digital converter (ADC) manufactured by National Semiconductor. It operates at a sampling rate of 65 MSPS with a power consumption of 370 mW under a single 3.3V supply. The device utilizes a pipeline architecture and features an internal reference buffer to simplify system design. It accepts differential analog inputs and provides parallel digital outputs. The component is housed in a 64-lead TQFP package and is rated for operation within the industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIVS' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the 3.3V power supply requirements are met within the specified tolerance. Check for RoHS compliance status if required by local regulations. Confirm availability through authorized distributors as this component may be from an older product line.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel conversion is required without external multiplexing. The internal reference simplifies board layout compared to external reference designs. Ensure the input signal bandwidth does not exceed the ADC's Nyquist frequency relative to the 65 MSPS clock. Compare SNR and SFDR specifications against application requirements for dynamic performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12DLxx series of low-power, high-speed dual ADCs from National Semiconductor. It shares architectural similarities with other members like the ADC12DL066 but differs in bit resolution and specific performance metrics. The series was designed to offer a balance between speed and power efficiency for portable and battery-operated applications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include the ADC12DL066CIVS/NOPB, which offers similar form factor but higher resolution capabilities. Verify pin-for-pin compatibility before substitution. Other family members such as the ADC12L080 may require schematic modifications due to different pin counts or interfaces.
