ADC10664CIWMX

Analog To Digital Converters (ADC) Overview

The ADC10664CIWMX is a 10-bit CMOS analog-to-digital converter featuring an internal four-channel input multiplexer and sample-and-hold circuit. Utilizing a patented multistep conversion technique, it achieves sub-microsecond conversion times with a typical duration of 360 ns and a maximum sampling rate of 1.5 MHz. The device operates on a single +5V supply and dissipates a maximum power of 235 mW. It requires no external clock and interfaces directly to microprocessors via tri-state outputs without additional logic.

Analog To Digital Converters (ADC) Feature Summary

• Four-channel analog input multiplexer controlled by S0 and S1 pins
• Built-in sample-and-hold circuit for accurate digitization of signals up to 250 kHz
• Speed adjust pin allows conversion time reduction via external resistor
• Tri-state digital outputs for direct microprocessor interface

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the component revision status as the datasheet indicates the related ADC10662 is obsolete. Confirm that the specific ordering suffix matches the required package and temperature range specifications. Ensure compatibility with existing system voltage levels and timing requirements before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a four-channel multiplexed input is required. The ADC10662 variant provides only two channels and is obsolete. Ensure the application source impedance remains below 500 ohms to maintain accuracy at the minimum sample time. Verify that the reference voltage span meets the linearity requirements for the specific operating mode.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC1066x family of 10-bit converters. It shares the same core architecture and electrical characteristics as the ADC10662 but includes an expanded four-input multiplexer. The CIWMX suffix denotes the commercial temperature range and surface-mount VQFN package configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC10662 is listed as obsolete in the documentation. For applications requiring only two inputs, the ADC10662 may be referenced for legacy design comparison, but the ADC10664 is the active four-channel solution within this product family.
