MAX480CSA Equivalent & Substitute Parts

Part Overview

The MAX480CSA is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, packaged in 8-SOIC surface mount configuration. This device is classified as obsolete product status. Due to its obsolete classification, equivalent and substitute parts with active product status are necessary for new designs and ongoing production requirements. Substitute parts maintain functional compatibility through matching electrical specifications and identical package geometry while offering improved availability and compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the MAX480CSA are grouped into two primary categories based on electrical parameter compatibility and product status:

Group 1: OP90 Series (OP90GSZ, OP90GSZ-REEL, OP90GSZ-REEL7)

The OP90 series maintains identical electrical specifications to the MAX480CSA across all critical parameters: slew rate (0.012 V/µs), supply voltage range (1.6 V to 36 V), supply current (14 µA), and output current (5 mA). These parts differ in input bias current (4 nA versus 1 nA) and input offset voltage (125 µV versus 25 µV), representing acceptable parameter variations within general-purpose amplifier tolerances. All OP90 variants use identical 8-SOIC packaging and are active products with RoHS3 compliance. Variants differ only in packaging format: tube, tape & reel, or cut tape & Digi-Reel.

Group 2: OP193 Series (OP193FSZ, OP193FSZ-REEL, OP193FSZ-REEL7)

The OP193 series provides rail-to-rail output capability with slightly enhanced electrical performance. These parts maintain the same 8-SOIC package and supply voltage range (1.7 V to 36 V minimum). Electrical differences include higher slew rate (0.015 V/µs), increased input bias current (20 nA), higher input offset voltage (150 µV), increased supply current (30 µA), and higher output current (25 mA). The OP193 series includes gain bandwidth product specification (35 kHz) not present in MAX480CSA. All OP193 variants are active products with RoHS3 compliance. Variants differ only in packaging format: tube, tape & reel, or cut tape & Digi-Reel.

Substitution logic is based on: identical package geometry (8-SOIC), compatible supply voltage ranges, matching number of circuits (1), surface mount mounting type, and active product status with modern compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Minimal Specification Change:

Select OP90GSZ, OP90GSZ-REEL, or OP90GSZ-REEL7. These parts provide the closest electrical match to MAX480CSA with identical slew rate (0.012 V/µs), supply current (14 µA), and output current (5 mA). All OP90 variants are active products with ROHS3 compliance certification, addressing the obsolete status and non-compliance issues of the original part. Choose packaging variant based on procurement requirements: tube for small quantities, tape & reel for standard production volumes, or cut tape & Digi-Reel for mixed-volume applications.

For Enhanced Performance with Increased Output Capability:

Select OP193FSZ, OP193FSZ-REEL, or OP193FSZ-REEL7. These parts provide rail-to-rail output operation with higher output current (25 mA versus 5 mA) and improved slew rate (0.015 V/µs versus 0.012 V/µs). The OP193 series accommodates applications requiring greater output drive capability while maintaining the same 8-SOIC package footprint. All OP193 variants are active products with ROHS3 compliance. Choose packaging variant based on procurement requirements.

Compliance Considerations:

All substitute parts carry ROHS3 compliance certification, addressing the RoHS non-compliance status of the obsolete MAX480CSA. All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the original part. All substitute parts are manufactured by Analog Devices Inc., ensuring consistent quality and technical support.

Frequently Asked Questions (FAQ)

Q: Can OP90GSZ directly replace MAX480CSA in existing designs?

A: Yes. The OP90GSZ maintains identical electrical specifications for slew rate, supply voltage range, supply current, and output current. The 8-SOIC package geometry is identical. Pin configuration compatibility must be verified against the specific application schematic, as all parts use standard 8-pin SOIC pinout. Input bias current and input offset voltage are slightly higher but remain within acceptable tolerances for general-purpose amplifier applications.

Q: What is the primary difference between OP90 and OP193 substitute options?

A: The OP193 series provides rail-to-rail output capability with higher output current (25 mA versus 5 mA) and faster slew rate (0.015 V/µs versus 0.012 V/µs). The OP90 series maintains closer electrical parity to the original MAX480CSA. Select OP90 for direct replacement; select OP193 for applications requiring enhanced output drive capability.

Q: Do packaging variants (tube, tape & reel, cut tape & Digi-Reel) affect electrical performance?

A: No. Packaging variants of the same base part number (OP90GSZ, OP90GSZ-REEL, OP90GSZ-REEL7 or OP193FSZ, OP193FSZ-REEL, OP193FSZ-REEL7) have identical electrical specifications. Packaging selection is based on procurement volume and assembly process requirements only.

Q: Are all substitute parts RoHS compliant?

A: Yes. All OP90 and OP193 variants carry ROHS3 compliance certification. The original MAX480CSA is RoHS non-compliant. Substitute parts address this compliance requirement for new designs and updated production.

Q: What is the operating temperature range difference?

A: MAX480CSA operates 0°C to 70°C. OP90 series operates -40°C to 85°C. OP193 series operates -40°C to 125°C. Substitute parts provide extended temperature range capability, beneficial for industrial and automotive applications.

Q: Can OP193 be used in applications originally designed for MAX480CSA?

A: Yes, with design verification. The OP193 provides enhanced performance (higher output current, faster slew rate, rail-to-rail output) and extended operating temperature range. These improvements are generally beneficial. However, the higher input bias current (20 nA versus 1 nA) and input offset voltage (150 µV versus 25 µV) may affect precision analog circuits. Application-specific testing is required for high-precision measurement circuits.

Q: Is the OP90 series the recommended first choice for MAX480CSA replacement?

A: Yes. The OP90 series provides the closest electrical match to MAX480CSA across all critical parameters while offering active product status and ROHS3 compliance. Select OP90 unless the application specifically requires the enhanced output current or rail-to-rail capability of the OP193 series.
