ADC10464CIWM

Analog To Digital Converters (ADC) Overview

The ADC10464CIWM is a 10-bit analog-to-digital converter manufactured by Texas Instruments, utilizing a patented multistep conversion technique. It features an internal sample-and-hold circuit and a four-channel input multiplexer. The device operates on a single +5V supply with a typical conversion time of 600 ns and a maximum power dissipation of 235 mW. It supports data rates up to 800 kHz and includes TRI-STATE outputs for direct microprocessor interfacing without external logic.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer origin as the datasheet originates from National Semiconductor, which was acquired by Texas Instruments. Confirm that the CIWM suffix denotes the M28B Small Outline package and industrial temperature range (-40°C to +85°C). Ensure compatibility with legacy National Semiconductor documentation when sourcing replacement units.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring fast 10-bit conversion with minimal external support circuitry. The ADC10464CIWM is suitable where a four-channel multiplexer is required within a single IC. Consider the 600 ns typical conversion time and 235 mW power consumption against system requirements. Ensure the analog source impedance is below 500 ohms for optimal accuracy at the minimum sample time.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC1046x family, which also includes the ADC10461 (single channel) and ADC10462 (two channels). The ADC10464CIWM specifically provides four selectable analog inputs. It serves as a high-speed alternative to slower successive-approximation converters while consuming less power than true flash architectures.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC10461 is pin-compatible but lacks the multiplexer. For direct replacement in existing designs, verify that the specific channel count matches the application needs. No other direct cross-model substitutes are documented in the provided datasheet.
