LT1216CS Equivalent & Substitute Parts

Part Overview

The LT1216CS is a general-purpose operational amplifier integrated circuit manufactured by Analog Devices Inc., configured as a 4-circuit device in a 16-SOIC surface mount package. This component is classified as a Last Time Buy product, indicating that it is no longer in active production and existing inventory represents the final availability from the manufacturer. The identification of equivalent and substitute parts is necessary to ensure design continuity, support long-term product availability, and provide alternatives for applications where the original part number may become unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT1216CS is determined by compatibility across the following critical parameters:

Functional Equivalence: Both the main part and substitute must be general-purpose operational amplifiers with 4 circuits in a 16-SOIC surface mount package to ensure direct pin-for-pin compatibility and identical board-level integration.

Electrical Performance Envelope: Substitute parts must operate within the defined voltage supply span (2.5 V to 36 V minimum and maximum) and support the required output current per channel (50 mA). The substitute part LT1214CS#TRPBF meets these requirements.

Compliance and Certification: Both parts must maintain RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating to satisfy regulatory and manufacturing process requirements.

Packaging Format: The substitute part is supplied in Tape & Reel (TR) format, which is compatible with automated assembly processes and represents a standard distribution method for surface mount components.

The LT1214CS#TRPBF is identified as the manufacturer-recommended substitute, offering active product status and extended availability compared to the Last Time Buy status of the LT1216CS.

Engineering Selection Recommendations

Product Status Consideration: The LT1216CS carries a Last Time Buy designation, signifying the end of its production lifecycle. The LT1214CS#TRPBF is classified as Active, ensuring ongoing availability and support from Analog Devices Inc.

Compliance Alignment: Both parts maintain identical RoHS3 compliance and MSL Level 1 ratings, satisfying regulatory requirements for electronics manufacturing and environmental standards.

Packaging and Distribution: The LT1214CS#TRPBF is supplied in Tape & Reel format, which is the standard distribution method for high-volume surface mount assembly operations and is compatible with automated pick-and-place equipment.

Electrical Performance: The LT1214CS#TRPBF demonstrates improved electrical characteristics in several parameters, including lower input bias current (90 nA versus 420 nA), reduced input offset voltage (150 µV versus 250 µV), and lower supply current consumption (3.4 mA versus 4.75 mA across four channels). The substitute part also provides an extended operating temperature range (−40°C to 85°C versus 0°C to 70°C).

Pin Compatibility: Both parts utilize the identical 16-SOIC package with matching pinout, enabling direct substitution without circuit board redesign or layout modification.

For applications requiring the LT1216CS, the LT1214CS#TRPBF is the manufacturer-recommended substitute that provides equivalent functionality with enhanced performance characteristics and active product status.

Frequently Asked Questions (FAQ)

Q: Can the LT1214CS#TRPBF be used as a direct replacement for the LT1216CS in existing designs?

A: Yes. Both parts are 4-circuit general-purpose operational amplifiers in identical 16-SOIC surface mount packages with matching pinouts. The LT1214CS#TRPBF is pin-for-pin compatible and requires no circuit modifications for substitution.

Q: What are the key differences between the LT1216CS and LT1214CS#TRPBF?

A: The primary differences are product status, operating temperature range, and electrical performance specifications. The LT1214CS#TRPBF is an active product with an extended temperature range (−40°C to 85°C), lower input bias current, reduced input offset voltage, and lower supply current consumption. The LT1216CS is designated Last Time Buy with a narrower operating temperature range (0°C to 70°C).

Q: Are both parts RoHS compliant?

A: Yes. Both the LT1216CS and LT1214CS#TRPBF are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: What is the significance of the Tape & Reel packaging for the LT1214CS#TRPBF?

A: Tape & Reel (TR) packaging is the standard format for automated surface mount assembly operations. It enables high-speed pick-and-place equipment integration and is suitable for production environments requiring continuous component feeding.

Q: Does the LT1214CS#TRPBF support the same supply voltage range as the LT1216CS?

A: Yes. Both parts support an identical supply voltage span from 2.5 V minimum to 36 V maximum, ensuring compatibility with the same power supply configurations.

Q: Why is the LT1214CS#TRPBF recommended over the LT1216CS?

A: The LT1214CS#TRPBF is recommended because it is an active product with ongoing manufacturer support and availability, whereas the LT1216CS is designated Last Time Buy. Additionally, the LT1214CS#TRPBF offers improved electrical performance characteristics and an extended operating temperature range.

Q: Can the LT1214CS#TRPBF be used in applications with operating temperatures below 0°C or above 70°C?

A: The LT1214CS#TRPBF supports operation from −40°C to 85°C, which extends beyond the 0°C to 70°C range of the LT1216CS. Applications requiring operation outside the LT1216CS temperature range can utilize the LT1214CS#TRPBF for expanded environmental capability.

Q: Are there any circuit design considerations when substituting the LT1214CS#TRPBF for the LT1216CS?

A: No circuit design modifications are required. The parts are functionally equivalent with identical pinouts and package dimensions. The improved electrical characteristics of the LT1214CS#TRPBF (lower bias current, reduced offset voltage, lower supply current) are beneficial for most applications.
