ADC10462CIWM

Analog To Digital Converters (ADC) Overview

The ADC10462CIWM is a 10-bit analog-to-digital converter manufactured by Texas Instruments, housed in a 20-lead Small Outline (SOIC) package. It utilizes a patented multistep conversion technique to achieve sub-microsecond performance with low power dissipation of up to 235 mW. The device features an internal sample-and-hold circuit and a two-channel input multiplexer, eliminating the need for external sampling components. It operates on a single +5V supply and includes a speed-adjust pin to reduce typical conversion time from 600 ns to 350 ns.

Analog To Digital Converters (ADC) Feature Summary

• Two-channel input multiplexer controlled by S0 logic pin
• Internal sample-and-hold circuit supporting signals up to 250 kHz
• Speed-adjust pin allows conversion time reduction to 350 ns
• Memory-mapped interface requiring no external logic

Analog To Digital Converters (ADC) Applications

• Digital signal processor front ends
• Instrumentation systems
• Disk drives
• Mobile telecommunications

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific CIWM suffix indicates the industrial temperature range (-40°C to +85°C) and SOIC package variant. Request original datasheets and material compliance documentation prior to acquisition.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a two-channel multiplexed input is required alongside high-speed conversion. The ADC10462 differs from the ADC10461 by including the multiplexer and speed-adjust functionality. Ensure the application source impedance remains 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. It serves as a high-speed upgrade path for legacy devices like the ADC1061 while maintaining pin compatibility. The CIWM suffix specifically denotes the industrial grade operating temperature range and surface-mount packaging.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC10461 is pin-compatible but lacks the multiplexer and speed-adjust features. Verify that the replacement supports the required channel count and timing constraints.
