AD7893ANZ-2 Equivalent & Substitute Parts

Part Overview

The AD7893ANZ-2 is a 12-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc., designed for single-ended input data acquisition applications. This SAR (Successive Approximation Register) architecture device operates at a 117 kSPS sampling rate with SPI digital interface and external voltage reference configuration. The component is actively produced and ROHS3 compliant, making it suitable for modern industrial and commercial applications requiring precision analog signal conversion in 8-DIP through-hole packaging.

Equivalent and substitute parts are identified when design flexibility, inventory availability, or supply chain optimization requires alternative sourcing while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD7893ANZ-2 are qualified based on strict parameter equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• 12-bit resolution
• 117 kSPS sampling rate
• Single-ended input configuration
• SPI digital interface
• SAR architecture
• External reference type
• 5V analog and digital supply voltages
• -40°C to 85°C operating temperature range
• 8-DIP through-hole package
• ROHS3 compliance

The AD7893ANZ-2 qualifies two parametric equivalents: AD7893ANZ-10 and AD7893BNZ-10. Both parts maintain identical electrical performance and physical packaging, differing only in manufacturing lot designation and temperature grade suffix, which do not affect functional compatibility within the specified operating range.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AD7893ANZ-2, AD7893ANZ-10, and AD7893BNZ-10—are actively produced by Analog Devices Inc. and maintain full ROHS3 compliance with unlimited moisture sensitivity level (MSL 1) ratings. Selection between these equivalents is based on inventory availability and supply chain requirements rather than functional performance differences.

The AD7893ANZ-2 maintains 2700 units in stock, while AD7893ANZ-10 provides 2100 units and AD7893BNZ-10 offers 1400 units. All parts are supplied in tube packaging and are suitable for direct substitution in applications requiring 12-bit SAR ADC functionality with external reference configuration and SPI interface.

Frequently Asked Questions (FAQ)

Q: Can AD7893ANZ-10 be used as a direct replacement for AD7893ANZ-2?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, sampling rate, package type, and operating temperature range. The suffix difference (-2 vs -10) indicates manufacturing lot designation and does not affect functional compatibility.

Q: What is the difference between AD7893ANZ-10 and AD7893BNZ-10?

A: Both parts maintain identical electrical and mechanical parameters. The difference in the part number suffix (ANZ vs BNZ) relates to manufacturing grade designation. Both are ROHS3 compliant and actively produced.

Q: Are these parts pin-compatible?

A: Yes. All three parts use the same 8-DIP (0.300", 7.62mm) through-hole package with identical pinout configuration, enabling direct PCB substitution without layout modifications.

Q: Do all substitute parts support the same SPI interface protocol?

A: Yes. All three parts implement identical SPI digital interface specifications with external voltage reference configuration, ensuring software and hardware compatibility across substitutions.

Q: What is the MSL rating for these components?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are these parts suitable for the same operating temperature applications?

A: Yes. All three parts operate across the identical -40°C to 85°C temperature range, supporting equivalent thermal performance in industrial and commercial environments.
