ADC10664CIWM

Analog To Digital Converters (ADC) Overview

The ADC10664CIWM 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 offers four analog input channels selectable via S0 and S1 pins, providing a minimum sampling rate of 1.5 MHz. Key electrical parameters include a typical conversion time of 360 ns, a total harmonic distortion of -60 dB (max) at 50 kHz, and a signal-to-noise ratio of 58 dB (min).

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as the datasheet indicates the ADC10662 is obsolete while describing the ADC10664. Confirm that the CIWM suffix corresponds to the commercial temperature range (-40°C to +85°C) and SOIC package type. Ensure sourcing from authorized distributors to guarantee production data integrity and standard warranty coverage.

Analog To Digital Converters (ADC) Selection Notes

Select this device when a single-supply 10-bit ADC with integrated multiplexing is required. It is suitable for applications needing up to 1.5 MHz sampling rates with low power consumption. Consider the trade-off between linearity and speed when utilizing the speed-adjust resistor, as faster modes may impact accuracy specifications.

Analog To Digital Converters (ADC) Part Context

The ADC10664 is part of the ADC1066x family, which includes variants like the ADC10662. This specific model provides four multiplexed inputs compared to the two-input ADC10662. It shares similar architectural features but differs in channel count and specific performance limits regarding conversion time and linearity errors defined in the Texas Instruments documentation.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC10662 is noted as obsolete in the documentation. For direct replacements within the same family, verify compatibility with the ADC10664 specifications. Other similar devices in the ADC1006x or ADC1046x families exist but have different specification limits for linearity and conversion time.
