ADC10662CIWM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC10662CIWM/NOPB is a 10-bit CMOS analog-to-digital converter featuring an internal multiplexer and sample-and-hold circuit. Utilizing a patented multistep conversion technique, it achieves sub-microsecond conversion times with a maximum power dissipation of 235 mW. The device operates on a single +5V supply without requiring an external clock. It includes a speed-adjust pin to optimize conversion time versus linearity trade-offs. The component provides tri-state digital outputs and interfaces directly with microprocessors.

• Digital signal processor front ends
• Instrumentation systems
• Disk drive controllers
• Mobile telecommunications equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the obsolete status of the ADC10662 series before procurement. Confirm that the CIWM suffix corresponds to the SOIC-16 package variant. Ensure design compatibility with the single +5V supply requirement and check if the specific performance limits meet application needs given the device's discontinued production status.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed 10-bit conversion with minimal power consumption. The multistep architecture reduces comparator count compared to true flash converters. Consider the trade-off between conversion speed and linearity when configuring the speed-adjust resistor. Ensure source impedance remains below 500 ohms for optimal accuracy at minimum sample times.

Analog To Digital Converters (ADC) Part Context

The ADC10662 is part of the ADC1066x family from Texas Instruments, which also includes the 4-channel ADC10664. These devices share the same core multistep conversion technology and electrical characteristics but differ in input channel count. The ADC10662 specifically offers two analog inputs controlled by the S0 pin.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC10662 is officially listed as obsolete. Designers should evaluate alternative components from the ADC1006x or ADC1046x families, noting differences in specification limits such as integral linearity error and total harmonic distortion. New designs may require migration to modern successors not explicitly listed in the legacy documentation.
