MIC916YQS-TR Equivalent & Substitute Parts

Part Overview

The MIC916YQS-TR is a voltage feedback amplifier integrated circuit manufactured by Microchip Technology, containing three independent amplifier circuits in a 16-QSOP surface mount package. This device is classified as obsolete, making identification of functionally compatible substitute components essential for ongoing design support and production continuity.

The MIC916YQS-TR operates across a supply voltage range of 5V to 18V with a slew rate of 270V/µs and gain bandwidth product of 135 MHz. With 927 pieces currently in stock, this part remains available for immediate procurement; however, designers and procurement teams should evaluate active alternative components to ensure long-term supply chain reliability and access to enhanced performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC916YQS-TR is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Amplifier topology: Voltage feedback configuration
• Circuit count: Three independent amplifier circuits
• Package type: 16-QSOP (16-SSOP equivalent)
• Mounting: Surface mount technology
• Operating temperature range: -40°C to 85°C minimum
• Supply voltage compatibility: Overlapping operational ranges
• RoHS and regulatory compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification

Secondary Compatibility Parameters:

• Slew rate performance
• Gain bandwidth product
• Input bias current and offset voltage specifications
• Output current capability per channel
• Supply current consumption

The MAX4382EEE+ from Analog Devices Inc./Maxim Integrated qualifies as a substitute based on matching package geometry, circuit count, amplifier type, temperature range, and regulatory compliance status. This part is currently in active production status with 3298 pieces available in inventory.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The MAX4382EEE+ is a direct functional substitute for the MIC916YQS-TR based on matching package geometry, circuit topology, and regulatory compliance. Both devices are ROHS3 compliant, REACH unaffected, and classified under EAR99 export control.

Product Status Consideration:

The MIC916YQS-TR is classified as obsolete. The MAX4382EEE+ is in active production status, ensuring continued availability and long-term supply chain stability. Selection of the MAX4382EEE+ eliminates obsolescence risk for new designs and ongoing production requirements.

Electrical Performance Differences:

The MAX4382EEE+ demonstrates enhanced performance characteristics compared to the MIC916YQS-TR:

• Slew rate increased from 270V/µs to 485V/µs
• -3dB bandwidth increased from 192 MHz to 210 MHz
• Rail-to-rail output capability (not specified for MIC916YQS-TR)

These performance improvements are compatible with applications designed for the MIC916YQS-TR and do not introduce incompatibility.

Supply Voltage Range:

The MIC916YQS-TR operates from 5V to 18V. The MAX4382EEE+ operates from 4.5V to 11V. Applications requiring supply voltages above 11V must retain the MIC916YQS-TR or identify alternative substitutes with higher maximum supply voltage ratings.

Power Consumption:

The MAX4382EEE+ exhibits higher supply current consumption (7.5mA vs. 2.4mA across three channels). Power budget analysis is required for battery-powered or low-power applications.

Frequently Asked Questions (FAQ)

Q: Can the MAX4382EEE+ directly replace the MIC916YQS-TR in existing PCB designs?

A: Yes, the MAX4382EEE+ is pin-compatible and functionally equivalent. Both devices use the 16-QSOP package with identical pinout and mechanical dimensions (16-SSOP, 0.154" width, 3.90mm). No PCB layout modifications are required.

Q: What are the key differences between these two parts?

A: The MAX4382EEE+ offers higher slew rate (485V/µs vs. 270V/µs), increased bandwidth (210 MHz vs. 192 MHz), and rail-to-rail output capability. However, it operates at lower maximum supply voltage (11V vs. 18V) and consumes more supply current (7.5mA vs. 2.4mA). Input bias current and offset voltage are also higher in the MAX4382EEE+.

Q: Why is the MIC916YQS-TR classified as obsolete?

A: Product status reflects manufacturer discontinuation. The MIC916YQS-TR is no longer in active production. Current inventory of 927 pieces is available, but long-term availability cannot be guaranteed. The MAX4382EEE+ is in active production and represents the recommended path forward.

Q: Is the MAX4382EEE+ suitable for applications requiring 18V supply voltage?

A: No. The MAX4382EEE+ maximum supply voltage is 11V. Applications requiring 18V operation must use the MIC916YQS-TR or identify alternative components with higher voltage ratings. Exceeding the maximum supply voltage specification will damage the device.

Q: What is the impact of higher supply current consumption in the MAX4382EEE+?

A: The MAX4382EEE+ draws 7.5mA total supply current (three channels) compared to 2.4mA for the MIC916YQS-TR. This 3.1x increase affects power dissipation and thermal management. Battery-powered or ultra-low-power applications may require thermal analysis or alternative component selection.

Q: Are both parts RoHS compliant?

A: Yes. Both the MIC916YQS-TR and MAX4382EEE+ are ROHS3 compliant and REACH unaffected. Both are classified under ECCN EAR99 for export control purposes.

Q: What is the difference in input offset voltage between these parts?

A: The MIC916YQS-TR has 1mV input offset voltage, while the MAX4382EEE+ has 3mV. For precision analog applications requiring minimal offset, the MIC916YQS-TR specification is superior. However, most applications can accommodate the 3mV offset through calibration or trimming circuits.

Q: Can I use the MAX4382EEE+ in a 5V-only application?

A: Yes. The MAX4382EEE+ operates from 4.5V minimum, making it suitable for 5V single-supply applications. The MIC916YQS-TR requires minimum 5V, so the MAX4382EEE+ provides slightly improved low-voltage margin.
