ADC10664CIWMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC10664CIWMX/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 and requires no external clock. It offers four analog input channels selectable via S0 and S1 pins, with a typical conversion time of 360 ns and a minimum sampling rate of 1.5 MHz. The part is housed in a VQFN-24 package.

• Single +5V Supply operation with low power consumption (max 235 mW)
• No External Clock Required; interface designed to appear as memory or I/O port
• Speed Adjust Pin allows reduction of conversion time to 360 ns using 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Verify the component status as the datasheet indicates the ADC10662 is obsolete while describing the ADC10664. Confirm availability through authorized Texas Instruments distributors or verified suppliers. Check for RoHS compliance details and ensure the specific ordering suffix matches the required package and temperature range specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this device when a fast, low-power 10-bit ADC with integrated multiplexing is required. Ensure the analog source impedance is less than 500 ohms to maintain accuracy at the minimum sample time. Verify that the reference voltage span is sufficient, as lower spans increase sensitivity but may degrade linearity. Consider the thermal resistance of the VQFN-24 package for heat dissipation in high-density designs.

Analog To Digital Converters (ADC) Part Context

The ADC10664 is part of the ADC1066x family, which includes variants like the ADC10662 (obsolete) and other models with different specification limits. This specific model provides four multiplexed inputs, distinguishing it from the two-input ADC10662. It shares the same multistep conversion architecture and performance characteristics regarding speed and power efficiency within the series.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements must match the 10-bit resolution, 4-channel multiplexer, and VQFN-24 package. Devices from the ADC1066x family with verified dynamic performance specs are functionally similar. Ensure any substitute supports the same +5V single supply and has comparable conversion times and power dissipation ratings.
