ADC11DL066CIVS/NOPB

Analog To Digital Converters (ADC) Overview

The ADC11DL066CIVS/NOPB is a dual-channel, 11-bit analog-to-digital converter from Texas Instruments. It operates at sampling rates up to 66 MSPS with a full power bandwidth of 450 MHz. The device utilizes a differential pipeline architecture with digital error correction and an internal reference. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 64 dB at 10 MHz input frequency and an Effective Number of Bits (ENOB) of 10.3 bits. Power consumption is 686 mW in active mode and reduces to 75 mW in power-down mode. It functions on a single +3.3V supply and supports output data formats of offset binary or two's complement.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix 'CIVS' corresponds to the commercial temperature range (-40°C to +85°C) and 'NOPB' indicates lead-free/RoHS compliance as per Texas Instruments documentation. Confirm package type is 64-lead TQFP. Ensure supply voltages VA and VD remain within +3.0V to +3.6V during operation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel high-speed conversion is required with low power constraints. The internal reference simplifies design compared to external reference solutions. Ensure the system can accommodate a 6-clock cycle latency. Verify that the input common-mode voltage range (0.5V to 1.8V) aligns with the sensor interface requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC11DL066 family of dual-channel pipeline ADCs. The 'CIVS' suffix typically denotes the industrial/commercial temperature grade and pin-compatible packaging variant. The 'NOPB' suffix signifies no lead-based plating. It serves as a monolithic CMOS solution integrating sample-and-hold circuits and digital correction logic to minimize die size.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-for-pin replacements may include other TI dual-channel pipeline ADCs such as the ADC10DL065, though resolution and speed differ. Cross-referencing datasheets for pinout compatibility and electrical parameter margins is essential before substitution.

Analog To Digital Converters (ADC) FAQ

What is the maximum clock frequency supported by the ADC11DL066?

The maximum clock frequency is 66 MHz, which corresponds to the 66 MSPS sampling rate.

How does the device handle output data formatting?

The Output Format (OF) pin allows selection between offset binary format (logic low) and two's complement format (logic high).

Can the digital output driver voltage be different from the main supply?

Yes, the VDR pin allows the output drivers to operate at a separate voltage between +2.4V and the VD supply voltage to ease interfacing with lower voltage systems.
