TLE2022ACD Equivalent & Substitute Parts

Part Overview

The TLE2022ACD is a general-purpose operational amplifier featuring dual circuits in an 8-SOIC surface mount package, manufactured by Texas Instruments under the Excalibur™ series. This device is designated as Last Time Buy, indicating discontinued production with limited inventory availability. The TLE2022ACD operates across a wide supply voltage range of 4V to 40V and is suitable for general-purpose amplification applications requiring moderate bandwidth and low input bias current characteristics.

Identification of equivalent and substitute parts is necessary due to the Last Time Buy status of the TLE2022ACD. Alternative components with compatible electrical and mechanical specifications ensure design continuity and long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2022ACD is determined by compatibility across the following critical parameters: dual-circuit general-purpose amplifier configuration, 8-SOIC surface mount package, supply voltage range spanning 4V to 40V minimum, and RoHS3 compliance. Substitute parts must maintain the same package footprint and pinout to ensure direct board-level replacement without layout modifications.

The substitute parts identified are grouped into two categories based on electrical performance alignment:

Category 1: Direct Electrical Match TLE2022ACDR maintains identical electrical specifications to the TLE2022ACD, differing only in packaging format (Cut Tape & Digi-Reel® versus Tube). This part is manufactured by the same supplier (Texas Instruments) and carries Active product status, ensuring continued availability.

Category 2: Compatible Alternative Performance ISL28207FBZ and ISL28227FBZ are manufactured by Renesas Electronics Corporation and operate within the specified supply voltage range and 8-SOIC package. These parts maintain dual-circuit general-purpose amplifier architecture with surface mount configuration and RoHS3 compliance. Electrical performance characteristics differ within acceptable substitution parameters for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

TLE2022ACDR is the primary substitute for TLE2022ACD. This part is manufactured by Texas Instruments and provides identical electrical specifications. The only difference is packaging format: TLE2022ACDR is supplied in Cut Tape & Digi-Reel® format rather than Tube. TLE2022ACDR carries Active product status with significantly higher inventory availability (16,204 units), ensuring reliable long-term supply. Both parts maintain identical moisture sensitivity levels and RoHS3 compliance. This substitution requires no circuit redesign or performance verification.

ISL28227FBZ is suitable for applications where higher bandwidth and faster slew rate are acceptable. This Renesas Electronics part offers 10 MHz gain bandwidth product and 3.6 V/µs slew rate compared to the TLE2022ACD's 2.8 MHz and 0.65 V/µs. ISL28227FBZ provides superior input offset voltage (10 µV versus 120 µV) and extremely low input bias current (1 nA versus 33 nA). Operating temperature range extends to -40°C to 125°C. Higher supply current (2.2 mA per channel) and moisture sensitivity level (MSL 2) must be evaluated against application requirements. This substitution is suitable for designs tolerating increased power consumption and requiring extended temperature operation.

ISL28207FBZ is suitable for low-power applications. This Renesas Electronics part offers the lowest supply current (210 µA per channel) and superior input characteristics (5 µV offset, 15 pA bias current). However, reduced bandwidth (1 MHz) and slower slew rate (0.32 V/µs) limit applicability to low-frequency signal processing. Operating temperature range extends to -40°C to 125°C. Moisture sensitivity level (MSL 2) requires one-year shelf life management. This substitution is appropriate only for applications where bandwidth and slew rate constraints are acceptable.

All substitute parts maintain 8-SOIC package compatibility, surface mount configuration, and RoHS3 compliance with the original TLE2022ACD.

Frequently Asked Questions (FAQ)

Q: Can TLE2022ACDR be used as a direct replacement for TLE2022ACD without circuit modifications?

A: Yes. TLE2022ACDR provides identical electrical specifications and operates within the same parameter ranges. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tube). No circuit redesign is required. Both parts are pin-compatible in 8-SOIC packages and maintain identical performance characteristics.

Q: What are the key differences between ISL28227FBZ and the original TLE2022ACD?

A: ISL28227FBZ offers significantly higher bandwidth (10 MHz versus 2.8 MHz) and faster slew rate (3.6 V/µs versus 0.65 V/µs). Input offset voltage is lower (10 µV versus 120 µV) and input bias current is substantially lower (1 nA versus 33 nA). Supply current per channel is higher (2.2 mA versus 550 µA total for two channels). Operating temperature range is extended (-40°C to 125°C versus 0°C to 70°C). These differences make ISL28227FBZ suitable for higher-frequency applications but with increased power consumption.

Q: Is ISL28207FBZ suitable for all applications using TLE2022ACD?

A: No. ISL28207FBZ is optimized for low-power operation with reduced bandwidth (1 MHz) and slower slew rate (0.32 V/µs). Applications requiring the original 2.8 MHz bandwidth or 0.65 V/µs slew rate cannot use ISL28207FBZ without circuit redesign. This part is appropriate only for low-frequency signal processing where power consumption is critical.

Q: Are all substitute parts available in the same 8-SOIC package?

A: Yes. All substitute parts (TLE2022ACDR, ISL28207FBZ, and ISL28227FBZ) are available in 8-SOIC (0.154", 3.90mm Width) surface mount packages. Direct board-level substitution is possible without layout modifications.

Q: What is the moisture sensitivity level difference between TLE2022ACD and the Renesas alternatives?

A: TLE2022ACD and TLE2022ACDR have MSL 1 (Unlimited shelf life). ISL28207FBZ and ISL28227FBZ have MSL 2 (1 Year shelf life). MSL 2 components require storage in controlled humidity environments and have a one-year maximum shelf life from the date of manufacture. This affects inventory management and component handling procedures.

Q: Why is TLE2022ACD designated as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part. Existing inventory will be depleted without replenishment. TLE2022ACDR (Active status) is the recommended long-term alternative from the same manufacturer with identical specifications.

Q: Can ISL28227FBZ be used in applications requiring the exact 0.65 V/µs slew rate of TLE2022ACD?

A: ISL28227FBZ has a slew rate of 3.6 V/µs, which exceeds the original specification. For applications with strict slew rate requirements, this faster response may introduce signal integrity issues or require circuit modifications. Verify that the higher slew rate does not adversely affect system performance before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TLE2022ACDR, ISL28207FBZ, and ISL28227FBZ are all RoHS3 compliant, matching the environmental compliance status of the original TLE2022ACD.
