ADS574JP Equivalent & Substitute Parts

Part Overview

The ADS574JP is a 12-bit Analog-to-Digital Converter (ADC) manufactured by Texas Instruments, featuring a single-ended input with SAR (Successive Approximation Register) architecture and a 40 kHz sampling rate. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The device operates with external or internal voltage references and is housed in a 28-pin DIP package suitable for through-hole mounting applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS574JP is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit ADC architecture
• Sampling Rate: 40 kHz conversion rate
• Input Configuration: Single-ended input with 1 channel
• Interface: Parallel data output
• Converter Architecture: SAR topology
• Reference Options: External and internal reference support
• Package: 28-pin DIP form factor with 0.600" (15.24mm) pitch
• Mounting: Through-hole technology
• Supply Voltage Compatibility: Digital supply at 5V; analog supply within specified ranges
• Operating Temperature Range: 0°C to 70°C
• Compliance: ROHS3 compliant

The MX574AJN+ from Analog Devices Inc./Maxim Integrated meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MX574AJN+ is the qualified substitute for the obsolete ADS574JP. Selection is based on the following engineering criteria:

• Functional Equivalence: Both devices share identical resolution (12-bit), sampling rate (40 kHz), input configuration (single-ended), and SAR architecture.
• Package Compatibility: Both use 28-pin DIP packaging with identical pitch (0.600"), enabling direct PCB footprint compatibility without layout modifications.
• Supply Voltage Alignment: Both operate with 5V digital supply and support the required analog supply voltage ranges for standard applications.
• Compliance Status: Both devices are ROHS3 compliant, meeting current environmental and regulatory requirements.
• Product Availability: The MX574AJN+ maintains active product status with documented inventory, ensuring long-term supply chain reliability compared to the obsolete ADS574JP.

Frequently Asked Questions (FAQ)
