ADC10662CIWMX

Analog To Digital Converters (ADC) Overview

The ADC10662CIWMX is a 10-bit analog-to-digital converter manufactured by National Semiconductor. It utilizes a patented multistep conversion technique to achieve sub-microsecond conversion times while maintaining low power dissipation of up to 235 mW. The device integrates a built-in sample-and-hold circuit and a 2-input multiplexer, eliminating the need for external components. It operates on a single +5V supply and requires no external clock. Typical conversion time is 360 ns, with a minimum sampling rate of 1.5 MHz.

Analog To Digital Converters (ADC) Feature Summary

• Built-in sample-and-hold circuit for accurate digitization of signals from DC to over 250 kHz
• Integrated 2-input analog multiplexer
• Single +5V power supply operation
• No external clock required

Analog To Digital Converters (ADC) Applications

• Data acquisition systems requiring fast conversion speeds
• Industrial control applications with multiple analog inputs
• Test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, following TI's acquisition of NS. Confirm the suffix 'CIWMX' corresponds to the commercial temperature range (-40°C to +85°C) and tape-and-reel packaging. Ensure the component is sourced from authorized distributors to avoid counterfeit parts, as this is a legacy device.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC10662CIWMX when a 10-bit resolution and high-speed conversion (360 ns typical) are required with minimal external circuitry. Choose this part over the ADC10664 if only two analog input channels are needed. Consider the power consumption of 235 mW maximum and the single +5V supply requirement during system design.

Analog To Digital Converters (ADC) Part Context

The ADC10662 is part of the ADC1066x family, which includes the 4-channel ADC10664. Both devices share the same core architecture based on multistep conversion technology. This family was designed to offer flash-like speed without the associated power and cost penalties of true flash ADCs. The CIWMX variant specifies the industrial/commercial temperature grade and surface-mount package.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements may be limited due to the legacy status of the National Semiconductor ADC1066x series. Check for updated equivalents from Texas Instruments or other manufacturers offering similar 10-bit, high-speed SAR ADCs with integrated multiplexers. Verify that any substitute matches the 360 ns conversion time and 235 mW power dissipation limits.
