LTC6263IMS#TRPBF Equivalent & Substitute Parts

Part Overview

The LTC6263IMS#TRPBF is a general purpose operational amplifier manufactured by Analog Devices Inc., featuring four independent circuits in a 16-MSOP surface mount package. This device is classified as a Last Time Buy product, indicating that the manufacturer has discontinued or will discontinue production. The rail-to-rail output configuration and low supply voltage requirement (1.8V minimum) make this amplifier suitable for battery-powered and low-voltage applications.

Due to the Last Time Buy status, identifying equivalent substitute parts with compatible electrical and mechanical characteristics is necessary for design continuity and long-term component availability.

Substitute Part Grouping Explanation

Substitution of the LTC6263IMS#TRPBF is determined by the following critical parameters:

Functional Compatibility Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 4 independent channels
• Output Type: Rail-to-Rail configuration
• Operating Temperature Range: -40°C to 85°C

Electrical Performance Parameters:

• Slew Rate: 7 V/µs (minimum acceptable performance)
• Gain Bandwidth Product: 30 MHz (minimum acceptable performance)
• Current - Input Bias: 10 nA (maximum acceptable leakage)
• Voltage - Input Offset: 50 µV (maximum acceptable offset)
• Current - Supply: 245 µA total (maximum acceptable quiescent current)
• Current - Output / Channel: 40 mA (minimum acceptable output drive)
• Voltage - Supply Span: 1.8V to 5.25V (operating range)

Physical and Compliance Parameters:

• Mounting Type: Surface Mount
• RoHS3 Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must maintain compatibility across all functional, electrical, and compliance criteria. Parts with superior electrical performance (higher slew rate, higher gain bandwidth product, higher output current) are acceptable substitutes provided they operate within the specified supply voltage range and maintain the same circuit count and output configuration.

Engineering Selection Recommendations

LT6222IGN#TRPBF Substitution Assessment:

The LT6222IGN#TRPBF is a direct functional substitute for the LTC6263IMS#TRPBF based on the following factors:

Compliance and Availability:

• Both parts are manufactured by Analog Devices Inc. and maintain ROHS3 compliance
• Both parts have Moisture Sensitivity Level 1 (Unlimited)
• The LT6222IGN#TRPBF holds Active product status, ensuring long-term availability and supply continuity
• The LTC6263IMS#TRPBF is designated Last Time Buy, making the LT6222IGN#TRPBF the appropriate alternative for new designs and ongoing production

Functional Compatibility:

• Both devices contain four independent general purpose operational amplifier circuits
• Both feature rail-to-rail output configuration
• Both operate across the -40°C to 85°C temperature range
• Both are surface mount devices suitable for automated assembly

Electrical Performance: The LT6222IGN#TRPBF demonstrates superior electrical performance across multiple parameters:

• Slew Rate: 20 V/µs (versus 7 V/µs) provides faster transient response
• Gain Bandwidth Product: 60 MHz (versus 30 MHz) enables higher frequency operation
• Current - Output / Channel: 50 mA (versus 40 mA) provides increased output drive capability

Supply Voltage Consideration: The LT6222IGN#TRPBF minimum supply voltage is 2.2V (versus 1.8V for the LTC6263IMS#TRPBF). Applications requiring operation below 2.2V require retention of the LTC6263IMS#TRPBF or identification of alternative parts with lower minimum supply voltage specifications.

Package Footprint Difference: The LT6222IGN#TRPBF uses 16-SSOP packaging (0.154", 3.90mm width) compared to the 16-TFSOP packaging (0.118", 3.00mm width) of the LTC6263IMS#TRPBF. PCB layout modification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the LT6222IGN#TRPBF be used as a direct replacement for the LTC6263IMS#TRPBF without circuit modification?

A: The LT6222IGN#TRPBF is functionally compatible and provides superior electrical performance. However, PCB layout modification is required due to package footprint differences (16-SSOP versus 16-TFSOP). Additionally, applications operating at supply voltages below 2.2V require retention of the LTC6263IMS#TRPBF, as the substitute part specifies a 2.2V minimum supply voltage.

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

A: The LT6222IGN#TRPBF provides higher slew rate (20 V/µs versus 7 V/µs), higher gain bandwidth product (60 MHz versus 30 MHz), and higher output current per channel (50 mA versus 40 mA). The LTC6263IMS#TRPBF operates at lower minimum supply voltage (1.8V versus 2.2V) and lower quiescent current (245 µA versus 900 µA total).

Q: Are both parts RoHS compliant?

A: Yes, both the LTC6263IMS#TRPBF and LT6222IGN#TRPBF are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited).

Q: Why is the LTC6263IMS#TRPBF designated as Last Time Buy?

A: Last Time Buy designation indicates that Analog Devices Inc. has discontinued or will discontinue production of this part. The LT6222IGN#TRPBF, with Active product status, is the recommended alternative for new designs and ongoing production requirements.

Q: What is the impact of the higher input bias current in the LT6222IGN#TRPBF?

A: The LT6222IGN#TRPBF has input bias current of 250 nA compared to 10 nA for the LTC6263IMS#TRPBF. This difference affects applications with high source impedance or precision transimpedance configurations. Applications sensitive to input bias current should evaluate circuit performance with the higher specification.

Q: Can the LT6222IGN#TRPBF operate at the same supply voltages as the LTC6263IMS#TRPBF?

A: The LT6222IGN#TRPBF operates from 2.2V to 12.6V, while the LTC6263IMS#TRPBF operates from 1.8V to 5.25V. The substitute part cannot operate below 2.2V. For applications requiring 1.8V to 2.2V operation, the LTC6263IMS#TRPBF must be retained.

Q: What package considerations apply to substitution?

A: The LTC6263IMS#TRPBF uses 16-TFSOP packaging (0.118" width, 3.00mm), while the LT6222IGN#TRPBF uses 16-SSOP packaging (0.154" width, 3.90mm). PCB footprint redesign is required for substitution. Both packages are surface mount and suitable for automated assembly.

Q: Is the higher quiescent current of the LT6222IGN#TRPBF a concern for battery-powered applications?

A: The LT6222IGN#TRPBF draws 900 µA total supply current compared to 245 µA for the LTC6263IMS#TRPBF. Battery-powered applications with strict power consumption requirements should evaluate the impact of this 3.7x increase in quiescent current on system runtime and power budget.
