TS982IDWT Equivalent & Substitute Parts

Part Overview

The TS982IDWT is a general purpose operational amplifier manufactured by STMicroelectronics, featuring dual circuits in a rail-to-rail configuration. This device is classified as an active linear amplifier component designed for general-purpose signal conditioning and amplification applications. The TS982IDWT maintains active product status with automotive-grade qualification under AEC-Q100 standards, supporting operating temperatures from -40°C to 125°C. Substitute parts are identified when equivalent functional performance is required due to component availability, supply chain constraints, or design flexibility within specified electrical and mechanical parameters.

Engineering Selection Recommendations

TS982IDWT Primary Application Context:

The TS982IDWT is specified for automotive-grade applications with AEC-Q100 qualification and extended operating temperature range (-40°C to 125°C). This device is suitable for applications requiring higher output current capability (200 mA per channel) and moderate slew rate performance (0.7 V/µs).

Substitute Selection Based on Application Requirements:

For Automotive and Extended Temperature Applications: NCS20032DR2G and NCV20032DR2G (onsemi) maintain the -40°C to 125°C operating temperature range and are suitable for automotive environments. These parts provide higher slew rate (8 V/µs) and gain bandwidth product (7 MHz) compared to the TS982IDWT, with lower supply current consumption (275 µA per channel). NCS20032DR2G offers higher output current per channel (96 mA) while NCV20032DR2G provides lower output current (14 mA).

For Standard Temperature Range Applications: MAX4471ESA+ and MAX4471ESA+T (Analog Devices Inc./Maxim Integrated) operate within -40°C to 85°C temperature range. These parts feature significantly lower supply current (750 nA per channel) and lower input bias current (200 pA), with reduced output current capability (36 mA per channel). These devices are suitable for low-power applications where extended temperature operation beyond 85°C is not required.

Compliance and Regulatory Considerations: All identified substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and active product status. Selection between substitutes should be based on specific application requirements for output current, slew rate, bandwidth, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can MAX4471ESA+ or MAX4471ESA+T be used as direct replacements for TS982IDWT in automotive applications?

A: MAX4471ESA+ and MAX4471ESA+T operate within -40°C to 85°C temperature range, which is narrower than the TS982IDWT specification of -40°C to 125°C. These parts are not suitable for applications requiring operation above 85°C. Additionally, output current per channel is limited to 36 mA compared to 200 mA for the TS982IDWT.

Q: What are the key differences between NCS20032DR2G and NCV20032DR2G?

A: Both NCS20032DR2G and NCV20032DR2G share identical electrical characteristics except for output current per channel. NCS20032DR2G provides 96 mA per channel output current, while NCV20032DR2G provides 14 mA per channel. Both maintain -40°C to 125°C operating temperature range and 8 V/µs slew rate. Selection depends on output current requirements for the specific application.

Q: Are all substitute parts available in the same package as TS982IDWT?

A: All substitute parts are available in 8-SOIC surface mount packages with 0.154" (3.90mm) width, matching the TS982IDWT package footprint. However, the TS982IDWT features an exposed pad variant, while substitute parts use standard 8-SOIC packages without exposed pads. PCB layout compatibility should be verified for thermal management considerations.

Q: What is the significance of supply voltage range differences between TS982IDWT and substitute parts?

A: The TS982IDWT specifies minimum supply voltage of 2.5V, while MAX4471ESA+/MAX4471ESA+T support 1.8V minimum and NCS20032DR2G/NCV20032DR2G support 1.7V minimum. All parts support maximum supply voltage of 5.5V. Applications requiring operation below 2.5V supply voltage must use substitute parts with lower minimum voltage specifications.

Q: How do slew rate and gain bandwidth product differences affect circuit performance?

A: The TS982IDWT provides 0.7 V/µs slew rate and 2.2 MHz gain bandwidth product. NCS20032DR2G and NCV20032DR2G offer significantly higher performance with 8 V/µs slew rate and 7 MHz bandwidth. MAX4471ESA+/MAX4471ESA+T provide lower performance with 0.002 V/µs slew rate and 9 kHz bandwidth. Selection depends on signal frequency content and transient response requirements of the application.

Q: What packaging options are available for substitute parts?

A: MAX4471ESA+ is supplied in Tube packaging, while MAX4471ESA+T is supplied in Tape & Reel packaging. NCS20032DR2G and NCV20032DR2G are supplied in Tape & Reel packaging. The TS982IDWT is available in Cut Tape and Digi-Reel packaging. Packaging selection affects component handling, storage, and automated assembly compatibility.

Q: Are all parts RoHS3 compliant and suitable for lead-free assembly?

A: All identified parts, including TS982IDWT and all substitute options, are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. All parts are suitable for lead-free soldering processes and meet environmental compliance requirements.
