HI3-574ALN-5

Analog To Digital Converters (ADC) Overview

The HI3-574ALN-5 is a high-speed, 12-bit analog-to-digital converter (ADC) manufactured by Harris Corporation. It utilizes Successive Approximation Register (SAR) architecture to achieve a sampling rate of 40 kSPS. The device features two single-ended analog inputs and operates with an analog supply voltage range of ±11.4V to 16.5V and a digital supply of 5V. It supports both external and internal reference types and includes optional address pins for system integration. The component is housed in a 28-pin CDIP package designed for through-hole mounting.

Analog To Digital Converters (ADC) Feature Summary

• High-speed 12-bit resolution using SAR architecture
• Dual single-ended analog input channels
• Flexible reference configuration supporting external or internal sources
• Optional address pin functionality for system addressing

Analog To Digital Converters (ADC) Applications

• Data acquisition systems requiring moderate speed and high resolution
• Industrial process control instrumentation
• Test and measurement equipment
• Signal conditioning modules

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'LN-5' against current manufacturer documentation to confirm pinout compatibility and electrical specifications. Check for End-of-Life (EOL) status as older Harris components may have limited availability. Ensure that the required analog supply voltages and 5V digital logic levels are supported by the target system design before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 40 kSPS sampling rate are required for dual-channel applications. Consider the through-hole CDIP package constraints for PCB layout. Evaluate the need for optional address pins if multiple converters are used in a single system. Compare performance against modern CMOS ADCs if lower power consumption or smaller form factors are critical.

Analog To Digital Converters (ADC) Part Context

This part belongs to the HI-574 series of monolithic 12-bit A/D converters from Harris Corporation. The series is characterized by its use of SAR technology and high-speed operation relative to contemporaneous devices.
