Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCP6V64T-E/ST is determined by alignment of the following critical parameters:

Functional Equivalence Criteria:

• Amplifier Type: Zero-Drift configuration
• Number of Circuits: 4 independent amplifier circuits
• Output Type: Rail-to-Rail output capability
• Package / Case: 14-TSSOP form factor with identical pin pitch and dimensions

Electrical Operating Range Criteria:

• Supply voltage compatibility within specified minimum and maximum ranges
• Operating temperature range coverage of -40°C to 125°C
• Surface mount mounting type for PCB assembly compatibility

Compliance & Environmental Criteria:

• RoHS3 compliance status
• Moisture Sensitivity Level MSL 1 classification
• REACH unaffected status

The AD8574ARUZ from Analog Devices Inc. meets these substitution criteria through identical package geometry, matching circuit count, rail-to-rail output configuration, and overlapping supply voltage and temperature operating ranges.

Engineering Selection Recommendations

MCP6V64T-E/ST Selection Basis:

• Primary choice for applications requiring minimum supply voltage of 1.8 V
• Optimized for low power consumption at 80 µA total supply current across four channels
• Suitable for battery-powered and ultra-low-power applications
• Active product status with established supply chain availability (743 pcs in stock)

AD8574ARUZ Selection Basis:

• Alternative for applications with minimum supply voltage requirement of 2.7 V or higher
• Provides enhanced gain bandwidth product of 1.5 MHz versus 1 MHz
• Delivers superior input offset voltage specification of 1 µV versus 8 µV
• Increased output current capability of 30 mA per channel versus 23 mA
• Active product status with higher inventory availability (1985 pcs in stock)
• Both devices maintain identical RoHS3 compliance, MSL 1 classification, and REACH unaffected status

Substitution Constraints:

• AD8574ARUZ requires minimum supply voltage of 2.7 V; designs operating below this threshold must use MCP6V64T-E/ST
• MCP6V64T-E/ST maximum supply voltage of 5.5 V accommodates wider supply ranges than AD8574ARUZ at 5 V maximum
• Both devices support identical operating temperature range and package footprint

Frequently Asked Questions (FAQ)

Q: Can AD8574ARUZ directly replace MCP6V64T-E/ST in all applications?

A: Direct replacement is possible only when the application supply voltage is 2.7 V or higher and does not exceed 5 V. Applications requiring supply voltages below 2.7 V or above 5 V cannot use AD8574ARUZ as a substitute.

Q: Are the package footprints identical between these two parts?

A: Yes. Both MCP6V64T-E/ST and AD8574ARUZ use the 14-TSSOP package with identical dimensions of 0.173" width and 4.40 mm width specification. PCB layout and reflow profiles remain unchanged during substitution.

Q: What are the key performance differences between these amplifiers?

A: The AD8574ARUZ provides higher gain bandwidth product (1.5 MHz versus 1 MHz), lower input offset voltage (1 µV versus 8 µV), and higher output current per channel (30 mA versus 23 mA). The MCP6V64T-E/ST offers lower supply current consumption (80 µA versus 850 µA) and extended minimum supply voltage operation (1.8 V versus 2.7 V).

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both MCP6V64T-E/ST and AD8574ARUZ are ROHS3 compliant, classified as MSL 1 (Unlimited), REACH unaffected, and rated for -40°C to 125°C operating temperature range.

Q: Which part should be selected for low-power battery applications?

A: MCP6V64T-E/ST is the appropriate selection for battery-powered designs due to its significantly lower supply current of 80 µA across four channels and extended minimum supply voltage operation down to 1.8 V.

Q: What is the impact of higher input bias current in AD8574ARUZ?

A: AD8574ARUZ specifies input bias current of 1 nA compared to 1 pA in MCP6V64T-E/ST. This difference is relevant only in applications with extremely high source impedance or where input bias current compensation is critical to circuit performance.

Q: Can these parts be used interchangeably in existing designs without circuit modification?

A: Interchangeability requires verification that the application supply voltage range falls within 2.7 V to 5 V. No circuit modifications are required for pin-compatible substitution when supply voltage constraints are satisfied.
