ADC10464CIWMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC10464CIWMX/NOPB is a 10-bit analog-to-digital converter featuring an internal four-channel input multiplexer and sample-and-hold circuit. Utilizing a patented multistep conversion technique, it achieves a typical conversion time of 600 ns with a maximum sampling rate of 800 kHz. The device operates on a single +5V supply and dissipates a maximum power of 235 mW. It provides tri-state digital outputs for direct microprocessor interfacing without external logic. Key performance metrics include a total harmonic distortion of -60 dB (max) at 50 kHz and no missing codes over the industrial temperature range.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix matches the required package type. The 'CIWM' designation indicates a 28-lead Small Outline package. Confirm the 'NOPB' suffix corresponds to lead-free and RoHS compliance requirements. Ensure the component meets the industrial operating temperature range of -40°C to +85°C for the intended application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a four-channel multiplexed input is required. The ADC10461 offers a single channel, while the ADC10462 provides two channels. All variants share similar electrical characteristics but differ in pin count and I/O configuration. Verify that the source impedance is below 500 ohms to maintain accuracy at the minimum sample time.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC1046x family developed by National Semiconductor, now part of Texas Instruments. The ADC10464 specifically adds a four-channel multiplexer compared to the single-channel ADC10461. It serves as a high-speed alternative to traditional successive-approximation converters, offering faster conversion times through its unique multistep architecture.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC10461 is noted as pin-compatible with the older ADC1061, providing an upgrade path for speed. No other direct cross-model replacements within this specific datasheet are listed for the four-channel variant.
