ADC10664CIWM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC10664CIWM/NOPB is a 10-bit CMOS analog-to-digital converter featuring an internal four-channel input multiplexer and sample-and-hold circuit. It utilizes a patented multistep conversion technique to achieve sub-microsecond conversion times with low power dissipation of 235 mW maximum. The device operates on a single +5V supply, eliminating the need for external clocks or interface logic. Key electrical parameters include a typical conversion time of 360 ns, a minimum sampling rate of 1.5 MHz, and a signal-to-noise ratio (SNR) of 60 dB at 50 kHz input frequency.

Analog To Digital Converters (ADC) Feature Summary

• Built-in four-channel analog input multiplexer controlled by S0/S1 pins
• Internal sample-and-hold circuit eliminates external components
• Single +5V supply operation with no external clock required
• Speed-adjust pin allows conversion time reduction via external resistor

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 that the component matches the SNAS076E datasheet revision from March 2013. Confirm the package marking corresponds to the TI WSM (Wide SOIC) variant. Ensure the NOPB suffix indicates lead-free compliance if required by the assembly process. Check for physical damage to the wide-body SOIC leads before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 10-bit resolution and up to 1.5 MHz sampling rate are sufficient. The ADC10664 is appropriate for applications requiring four differential or single-ended inputs without external multiplexers. Consider the 360 ns typical conversion time against system timing requirements. Verify that the source impedance is below 500 ohms to maintain accuracy at the specified sampling rates.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC1066x family, which includes the obsolete ADC10662 (two-channel). The ADC10664 specifically provides four analog inputs compared to the two in the ADC10662. Both devices share the same core multistep architecture and electrical characteristics, differing primarily in the multiplexer configuration and pin count.
