MAX192ACAP Equivalent & Substitute Parts

Part Overview

The MAX192ACAP is a 10-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring SAR (Successive Approximation Register) architecture. This component features 4 or 8 differential/single-ended inputs with a sampling rate of 133 kSPS and SPI data interface compatibility.

The MAX192ACAP is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support legacy system maintenance or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX192ACAP is determined by the following critical parameters:

• Resolution: 10-bit ADC architecture
• Sampling Rate: 133 kSPS minimum performance
• Input Configuration: Support for 4 or 8 channels with differential and single-ended input capability
• Data Interface: SPI-compatible serial communication protocol
• Package: 20-SSOP form factor for surface mount assembly
• Supply Voltage: 5V analog and digital supply compatibility
• Operating Temperature Range: 0°C to 70°C minimum

The MAX192ACAP+ qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX192ACAP+ is the direct substitute for the MAX192ACAP. Both components share identical resolution, sampling rate, package form factor, and operating temperature specifications. The MAX192ACAP+ offers the following advantages:

• Active product status ensures ongoing manufacturer support and availability
• ROHS3 compliance satisfies modern environmental and regulatory requirements
• Enhanced data interface support (MICROWIRE™, QSPI™, Serial, SPI™) provides greater design flexibility while maintaining SPI backward compatibility
• Identical pinout and package dimensions enable direct board-level replacement

For new designs or system redesigns, the MAX192ACAP+ is the recommended selection. For legacy system maintenance requiring the exact original part, the MAX192ACAP remains available in limited inventory.

Frequently Asked Questions (FAQ)

Q: Can the MAX192ACAP+ directly replace the MAX192ACAP in existing designs?

A: Yes. Both components share identical 10-bit resolution, 133 kSPS sampling rate, 20-SSOP package, and SPI data interface. The pinout and electrical characteristics are compatible for direct substitution.

Q: What is the primary difference between these two parts?

A: The MAX192ACAP+ is an active product with ROHS3 compliance, while the MAX192ACAP is obsolete and RoHS non-compliant. The MAX192ACAP+ also supports additional serial interface protocols (MICROWIRE™, QSPI™) beyond SPI.

Q: Are there any supply voltage differences?

A: The MAX192ACAP operates on 5V single supply (analog and digital). The MAX192ACAP+ operates on ±5V supply. Circuit design must accommodate this difference if substituting in existing applications.

Q: Does the package form factor remain the same?

A: Yes. Both components use the 20-SSOP (0.209", 5.30mm Width) surface mount package with identical pinout and mechanical dimensions.

Q: Which part should be selected for new designs?

A: The MAX192ACAP+ should be selected for new designs due to active product status, regulatory compliance, and ongoing manufacturer support.
