ADC10064CIWM

Analog To Digital Converters (ADC) Overview

The ADC10064CIWM is a 10-bit, 800 kHz analog-to-digital converter featuring an internal sample-and-hold and a four-channel input multiplexer. Utilizing a patented multistep conversion architecture, it achieves sub-microsecond conversion times with low power dissipation of 235 mW maximum. The device operates on a single +5V supply and provides parallel tri-state digital outputs for direct microprocessor interfacing. It includes a speed-adjust pin to reduce typical conversion time to 350 ns. The component is housed in a 28-pin SOIC package and supports industrial temperature ranges from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

This specific part number is classified as obsolete by Texas Instruments. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life status. Designers should confirm if the obsolete designation applies to the CIWM suffix specifically or the entire family before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC10064CIWM when four independent analog inputs require digitization at speeds up to 800 kHz. Ensure the application can accommodate the 28-pin SOIC footprint. Verify that the system power supply remains stable at +5V, as the device lacks internal voltage regulation. Consider the ADC10664 series if faster conversion speeds are required, noting potential specification differences.

Analog To Digital Converters (ADC) Part Context

The ADC10064 belongs to the ADC1006x family, which also includes the single-channel ADC10061 and dual-channel ADC10062. These devices share the same multistep conversion core but differ in input count and pinout configurations. The ADC10064 specifically integrates four analog inputs, making it distinct within this legacy product line for multi-channel data acquisition tasks.

Analog To Digital Converters (ADC) Replacement Considerations

Texas Instruments lists the ADC10064 as obsolete. The datasheet explicitly directs users to the ADC10662/ADC10664 for high-speed ensured performance. Engineers should evaluate the ADC10664 as the primary functional replacement, accounting for differences in conversion time specifications and potentially updated packaging options.
