ADC11L066CIVY

Analog To Digital Converters (ADC) Overview

The ADC11L066CIVY is a monolithic CMOS analog-to-digital converter manufactured by National Semiconductor. It provides 11-bit resolution with a sampling rate of 65 MSPS. The device utilizes a differential pipeline architecture with digital error correction and an on-chip sample-and-hold circuit to minimize die size and power consumption while maintaining excellent dynamic performance. Operating on a single +3V supply, the ADC11L066 consumes 240mW at full speed. It features a buffered, high-impedance, single-ended reference input converted on-chip to a differential reference. Output data format is 11-bit offset binary. The component operates over the industrial temperature range of -40°C to +85°C and is available in a 16-lead MSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer origin as National Semiconductor or Texas Instruments, noting that National Semiconductor was acquired by TI. Confirm the specific suffix 'CIVY' corresponds to the correct package (MSOP) and temperature grade (-40°C to +85°C). Ensure the datasheet matches the 11-bit, 65 MSPS specifications rather than similar models like the ADC12L066 which offers 12-bit resolution.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 11-bit resolution and 65 MSPS throughput are required with low power consumption from a single 3V supply. Compare against the ADC12L066 if higher resolution is needed, or the ADC11L063 for lower speed requirements. Consider the MSOP package constraints for PCB layout. Verify compatibility with system voltage levels, as outputs are 1.8V to 3.3V compatible.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC11L/ADC12L family of low-power, high-speed analog-to-digital converters. These devices share a common architecture but differ in resolution and speed. The ADC11L066 specifically targets applications requiring a balance between resolution and speed under tight power budgets, serving as a predecessor or variant to the more widely documented ADC12L066 series.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC12L066 is a pin-compatible upgrade offering 12-bit resolution. The ADC11L063 offers lower speed but may be suitable for cost-sensitive applications. Verify pinout compatibility before substitution.
