ADC10662CIWM

Analog To Digital Converters (ADC) Overview

The ADC10662CIWM is a 10-bit analog-to-digital converter manufactured by National Semiconductor. It utilizes a patented multistep conversion technique to achieve sub-microsecond performance, completing a 10-bit conversion in 360 ns typical and 466 ns maximum over temperature. The device features an internal sample-and-hold circuit and a built-in input multiplexer with two channels. It operates on a single +5V supply with a maximum power dissipation of 235 mW. Dynamic performance specifications, including total harmonic distortion and signal-to-noise ratio, are guaranteed alongside standard static linearity parameters.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIWM' against official National Semiconductor documentation to confirm package type and temperature range. Ensure compatibility with single +5V supply requirements and check for obsolescence status given the June 1999 datasheet date. Confirm pinout alignment if replacing existing designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution is required with conversion speeds under 500 ns. The ADC10662 is suitable for applications needing multiple analog inputs without external switching hardware. Consider the ADC10664 variant if four input channels are necessary instead of two.

Analog To Digital Converters (ADC) Part Context

The ADC10662 belongs to a family of high-speed CMOS analog-to-digital converters that employ a unique multistep flash technique. This approach reduces power dissipation compared to true flash architectures while maintaining high throughput. The device is designed for ease of microprocessor interfacing through its memory-mapped output structure.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC10664 serves as a functional alternative within the same series, offering identical electrical characteristics but with a four-input multiplexer instead of two.
