Substitute Part Grouping Explanation

Substitution of the TS1852AIPT is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 2 (dual-channel configuration)
• Output Type: Rail-to-Rail
• Package / Case: 8-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply Span: Minimum 1.8 V, Maximum 6 V (or compatible range)
• Operating Temperature: -40°C ~ 125°C (or compatible range)

Secondary Compatibility Factors:

• RoHS3 Compliance
• Moisture Sensitivity Level (MSL): 1
• Surface mount compatibility with existing PCB layouts

Substitute parts are grouped into two categories based on packaging configuration: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® variants. All identified substitutes maintain electrical and mechanical compatibility within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status, ensuring ongoing availability and manufacturer support. Selection among substitute options depends on specific application requirements and operational constraints:

onsemi NCS20082DTBR2G / NCV20082DTBR2G: These parts provide moderate performance characteristics with 1.2 MHz gain bandwidth product and 0.4 V/µs slew rate. Supply voltage range extends to 5.5 V maximum. Current consumption is significantly lower than the TS1852AIPT (48 µA per channel). Output current capability is reduced to 15 mA per channel. Both parts maintain the full -40°C ~ 125°C operating temperature range and are available in Tape & Reel packaging.

onsemi NCS20092DTBR2G / NCV20092DTBR2G: These parts offer the lowest power consumption (23 µA per channel) with reduced output current capability (8.5 mA per channel). Gain bandwidth product is 350 kHz, closely matching the TS1852AIPT specification. Slew rate is reduced to 0.15-0.17 V/µs. These parts are suitable for ultra-low-power applications with moderate bandwidth requirements and are available in Tape & Reel packaging.

Analog Devices AD8532ARUZ / AD8532ARUZ-REEL: These parts deliver superior performance with 3 MHz gain bandwidth product, 5 V/µs slew rate, and 250 mA output current per channel. However, the operating temperature range is limited to -40°C ~ 85°C, and the minimum supply voltage is 2.7 V. Supply current consumption is higher at 750 µA per channel. AD8532ARUZ is packaged in Tube format, while AD8532ARUZ-REEL is available in Cut Tape & Digi-Reel® format for higher-volume applications.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical 8-TSSOP package geometry, ensuring direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TS1852AIPT be directly replaced with any of the listed substitute parts?

A: Direct replacement is possible only when the application requirements align with the substitute part's electrical specifications. All listed substitutes share identical package geometry (8-TSSOP) and mounting type (surface mount), enabling physical compatibility. However, electrical parameters such as slew rate, gain bandwidth product, output current, and supply current differ. Applications must tolerate these parameter variations or require circuit redesign to accommodate the substitute part's characteristics.

Q: What is the primary difference between onsemi NCS and NCV variants?

A: The NCS and NCV designations represent different product lines within onsemi's operational amplifier portfolio. Both NCS20082DTBR2G and NCV20082DTBR2G share identical electrical specifications and are functionally equivalent. The designation difference reflects internal onsemi product categorization and does not affect substitution compatibility. Both variants are available in Tape & Reel packaging and maintain the same performance characteristics.

Q: Why do the AD8532ARUZ and AD8532ARUZ-REEL parts have different packaging but identical electrical specifications?

A: AD8532ARUZ is supplied in Tube packaging, suitable for lower-volume applications and manual assembly processes. AD8532ARUZ-REEL is supplied in Cut Tape & Digi-Reel® format, optimized for automated pick-and-place assembly and higher-volume production. The electrical specifications are identical; packaging selection depends on manufacturing process requirements and production volume.

Q: Which substitute part is most suitable for applications requiring the lowest power consumption?

A: The onsemi NCS20092DTBR2G and NCV20092DTBR2G parts offer the lowest supply current at 23 µA per channel, compared to 162 µA for the TS1852AIPT. These parts are appropriate for battery-powered and energy-constrained applications. However, output current capability is limited to 8.5 mA per channel, and gain bandwidth product is reduced to 350 kHz. Application requirements must accommodate these performance trade-offs.

Q: Are there any temperature range limitations when substituting the TS1852AIPT?

A: The TS1852AIPT operates across -40°C ~ 125°C. All onsemi substitute parts (NCS20082DTBR2G, NCS20092DTBR2G, NCV20082DTBR2G, NCV20092DTBR2G) maintain this full temperature range. The Analog Devices AD8532ARUZ and AD8532ARUZ-REEL parts are limited to -40°C ~ 85°C. Applications requiring operation above 85°C must use onsemi alternatives or the original TS1852AIPT if available.

Q: What is the impact of different supply voltage ranges on substitution?

A: The TS1852AIPT operates from 1.8 V to 6 V. onsemi substitutes operate from 1.8 V to 5.5 V, providing full compatibility for applications within the 1.8 V to 5.5 V range. Analog Devices AD8532ARUZ and AD8532ARUZ-REEL require a minimum of 2.7 V, limiting compatibility with applications using 1.8 V to 2.6 V supply voltages. Applications operating at the lower voltage boundary must verify substitute part compatibility.

Q: How do output current specifications affect circuit design when substituting parts?

A: The TS1852AIPT provides 48 mA output current per channel. onsemi NCS20082DTBR2G and NCV20082DTBR2G provide 15 mA per channel, while NCS20092DTBR2G and NCV20092DTBR2G provide 8.5 mA per channel. Analog Devices AD8532ARUZ and AD8532ARUZ-REEL provide 250 mA per channel. Applications requiring output currents exceeding the substitute part's capability require additional output buffering or current amplification stages. Conversely, applications with modest output current requirements can use lower-current substitutes without modification.

Q: Is the TS1852AIPT still available for new designs?

A: The TS1852AIPT is classified as obsolete, indicating discontinued production. New designs should not incorporate this part number. Existing designs utilizing the TS1852AIPT should transition to active substitute parts to ensure long-term supply chain reliability and manufacturer support. All listed substitute parts maintain active product status with established distribution channels.
