ISL28233FRZ-T13 Equivalent & Substitute Parts

Part Overview

The ISL28233FRZ-T13 is a zero-drift operational amplifier manufactured by Renesas Electronics Corporation, configured as a dual-channel (2 circuit) device in an 8-DFN surface mount package. This device is classified as a linear amplifier with rail-to-rail output capability and is actively produced. The ISL28233FRZ-T13 serves applications requiring precision amplification with minimal input offset voltage and low input bias current characteristics. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameter constraints, or when supply chain considerations necessitate alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISL28233FRZ-T13 is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of circuits: 2 (dual-channel configuration)
• Output type: Rail-to-Rail
• Mounting type: Surface Mount
• Package category: 8-pin DFN/SON (3x3 mm footprint)
• Operating temperature range: -40°C to 125°C
• Supply voltage span minimum: 1.8 V or lower
• Supply voltage span maximum: 5.5 V or higher
• RoHS3 compliance
• MSL rating: 2 or better

Secondary Compatibility Factors:

• Amplifier type (zero-drift, general purpose, or CMOS variants)
• Slew rate and gain bandwidth product (performance characteristics)
• Input bias current and input offset voltage (precision characteristics)
• Supply current and output current per channel

The substitute parts identified (OPA2313IDRGR, OPA2313IDRGT, OPA2314AIDRBT) meet the primary substitution criteria. Differences in amplifier type and performance characteristics are noted in the parameter comparison table to enable informed selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance with matching MSL ratings. Selection between the ISL28233FRZ-T13 and substitute devices is based on the following engineering considerations:

ISL28233FRZ-T13 (Renesas Electronics): The zero-drift amplifier topology provides superior input offset voltage performance (2 µV) and higher input bias current (180 pA) compared to general-purpose alternatives. Supply voltage range extends to 6 V maximum. This device is appropriate for precision analog signal conditioning applications where offset voltage minimization is critical.

OPA2313IDRGR and OPA2313IDRGT (Texas Instruments, General Purpose): Both variants feature identical electrical specifications with general-purpose amplifier topology. The OPA2313IDRGT is supplied in Tape & Reel packaging, while OPA2313IDRGR is supplied in Cut Tape & Digi-Reel format. These devices exhibit higher input bias current (0.2 pA) and input offset voltage (500 µV) but offer increased slew rate (0.5 V/µs) and gain bandwidth product (1 MHz). Maximum supply voltage is limited to 5.5 V. Selection of these variants is appropriate when higher bandwidth performance is required and precision offset voltage is not a primary constraint.

OPA2314AIDRBT (Texas Instruments, CMOS): The CMOS amplifier variant provides the highest slew rate (1.5 V/µs) and gain bandwidth product (3 MHz) among substitute options. Supply current is elevated to 150 µA across both channels. Maximum supply voltage is 5.5 V. This device is suitable for applications requiring higher frequency response and faster transient performance, with acceptance of increased power consumption.

All substitute parts are compatible with the -40°C to 125°C operating temperature range and maintain surface mount configuration in 8-pin packages with exposed pad design.

Frequently Asked Questions (FAQ)

Q: Can the OPA2313 series directly replace the ISL28233FRZ-T13 in existing PCB layouts?

A: Package compatibility requires verification. The ISL28233FRZ-T13 uses 8-VDFN Exposed Pad packaging, while OPA2313 variants use 8-WFDFN Exposed Pad packaging. Both are 3x3 mm footprints with 8-pin configuration and exposed pad design. PCB layout compatibility depends on specific pad dimensions and thermal via placement. The OPA2314AIDRBT uses 8-VDFN Exposed Pad packaging, matching the ISL28233FRZ-T13 footprint.

Q: What are the key electrical differences between zero-drift and general-purpose amplifier topologies?

A: The ISL28233FRZ-T13 zero-drift topology achieves 2 µV input offset voltage through continuous offset correction. The OPA2313 general-purpose devices specify 500 µV input offset voltage. Zero-drift amplifiers are appropriate for precision measurement and signal conditioning. General-purpose amplifiers offer simpler design and lower cost when offset voltage specifications of 500 µV or greater are acceptable.

Q: Is the OPA2314AIDRBT suitable for low-power applications?

A: The OPA2314AIDRBT supply current specification is 150 µA across both channels, compared to 18 µA for the ISL28233FRZ-T13 and 50 µA for the OPA2313 variants. The OPA2314AIDRBT is not appropriate for battery-powered or ultra-low-power applications. Selection of this device is limited to applications where higher bandwidth performance justifies increased power consumption.

Q: What is the maximum supply voltage for each substitute part?

A: The ISL28233FRZ-T13 supports supply voltage up to 6 V. All Texas Instruments substitute parts (OPA2313IDRGR, OPA2313IDRGT, OPA2314AIDRBT) are limited to 5.5 V maximum supply voltage. Applications requiring operation above 5.5 V cannot use these substitutes.

Q: Are all substitute parts available in the same packaging format?

A: The OPA2313IDRGT is supplied in Tape & Reel (TR) packaging, matching the ISL28233FRZ-T13 format. The OPA2313IDRGR is supplied in Cut Tape (CT) & Digi-Reel format. The OPA2314AIDRBT is supplied in Tape & Reel (TR) packaging. Packaging format selection depends on manufacturing assembly requirements and component handling procedures.

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

A: All identified parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 2 (1 Year). All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001. All parts operate across the -40°C to 125°C temperature range. Compliance and environmental specifications are equivalent across all options.
