TS1852ID Equivalent & Substitute Parts

Part Overview

The TS1852ID is a general-purpose operational amplifier manufactured by STMicroelectronics, configured as a dual-circuit (2-channel) rail-to-rail amplifier in an 8-SOIC surface-mount package. This device is classified as obsolete, indicating discontinued production and limited availability in the market. The TS1852ID was designed for applications requiring low-power, general-purpose amplification with rail-to-rail output capability across a 1.8 V to 6 V supply range.

Due to its obsolete status, sourcing new original units presents supply chain challenges. Equivalent and substitute parts listed in this reference provide active alternatives that maintain functional compatibility through matching package geometry, circuit configuration, and core electrical parameters necessary for direct replacement in existing designs.

Engineering Selection Recommendations

Primary Substitutes for Direct Replacement:

The AD8542ARZ, AD8542ARZ-REEL, and AD8542ARZ-REEL7 devices are the closest functional equivalents to the TS1852ID. These parts maintain the full operating temperature range of -40°C to 125°C, matching the TS1852ID specification. The AD8542 series exhibits improved input bias current performance (4 pA versus 16 nA) while maintaining identical voltage input offset (1 mV). The slew rate is higher at 0.92 V/µs compared to 0.25 V/µs, providing enhanced transient response. All three variants are active products with ROHS3 compliance and MSL 1 classification, ensuring long-term availability and manufacturing compatibility.

The AD8542 series operates within a reduced maximum supply voltage of 5.5 V compared to the TS1852ID's 6 V maximum. Applications operating at or near 6 V supply must be evaluated for compatibility. The minimum supply voltage increases from 1.8 V to 2.7 V, which may impact ultra-low-voltage applications.

Secondary Substitutes for Enhanced Performance Applications:

The AD8532ARZ, AD8532ARZ-REEL, and AD8532ARZ-REEL7 devices provide significantly enhanced performance with 5 V/µs slew rate and 3 MHz gain bandwidth product. These parts are suitable for applications requiring higher bandwidth and faster transient response. However, the operating temperature range is limited to -40°C to 85°C, which does not meet the TS1852ID's 125°C upper temperature specification. These devices are appropriate only for applications operating within the -40°C to 85°C range.

CMOS Alternative for Ultra-Low Input Bias Current Applications:

The AD8602ARZ, AD8602ARZ-REEL, AD8602ARZ-REEL7, and AD8602DRZ devices represent the DigiTrim® CMOS amplifier series with exceptional input bias current performance (0.2 pA). These parts offer the highest slew rate (6 V/µs) and gain bandwidth product (8.4 MHz) among all listed substitutes. The AD8602 series maintains the full -40°C to 125°C operating temperature range and operates within the 2.7 V to 5.5 V supply range. The AD8602ARZ and AD8602DRZ variants differ in voltage input offset specification (80 µV versus 1.3 mV), with the AD8602DRZ providing tighter offset tolerance. These devices are suitable for precision instrumentation and high-impedance input applications where input bias current minimization is critical.

All substitute parts listed are active products with confirmed ROHS3 compliance and MSL 1 classification, supporting long-term design reliability and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can the AD8532 series directly replace the TS1852ID in all applications?

A: The AD8532 series provides package and circuit configuration compatibility but operates only to 85°C maximum temperature. Applications requiring operation at temperatures above 85°C must use the AD8542 or AD8602 series instead. Additionally, the AD8532 series maximum supply voltage is 6 V, matching the TS1852ID, but the minimum supply voltage increases to 2.7 V from 1.8 V.

Q: What is the primary difference between AD8542ARZ, AD8542ARZ-REEL, and AD8542ARZ-REEL7?

A: These three part numbers represent the same device with different packaging and delivery formats. AD8542ARZ is supplied in tube packaging. AD8542ARZ-REEL and AD8542ARZ-REEL7 are supplied on cut tape and Digi-Reel® formats for automated assembly. Electrical specifications and performance characteristics are identical across all three variants.

Q: Is the TS1852ID pin-compatible with the substitute parts listed?

A: All substitute parts use the 8-SOIC package with identical 0.154" (3.90mm) width. The 8-SOIC package maintains standard pin spacing and configuration. Pin-level compatibility must be verified against the specific application schematic, as operational amplifier pinouts are standardized but functional application requirements may vary.

Q: Which substitute part offers the lowest power consumption?

A: The AD8542 series offers the lowest supply current at 45 µA per dual-channel configuration, compared to the TS1852ID's 162 µA. This represents a 72% reduction in supply current, making the AD8542 series suitable for battery-powered and low-power applications.

Q: Can I use the AD8602 series in place of the TS1852ID for general-purpose amplification?

A: Yes. The AD8602 series provides full functional compatibility with enhanced performance characteristics. The AD8602 series offers superior slew rate (6 V/µs), gain bandwidth product (8.4 MHz), and input bias current (0.2 pA). The maximum supply voltage is 5.5 V, which is 0.5 V lower than the TS1852ID. Applications operating at 6 V supply must be evaluated for compatibility.

Q: What is the significance of the MSL 1 classification for all listed parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. All parts listed maintain MSL 1 classification, eliminating the need for specialized dry-pack storage or baking procedures prior to assembly. This simplifies inventory management and reduces manufacturing process complexity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, confirming the absence of restricted substances (lead, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers) in accordance with EU Directive 2011/65/EU. This ensures compatibility with modern manufacturing standards and environmental regulations.

Q: What is the difference between the AD8602ARZ and AD8602DRZ variants?

A: Both devices are CMOS amplifiers with identical slew rate (6 V/µs) and gain bandwidth product (8.4 MHz). The primary difference is voltage input offset specification: AD8602ARZ specifies 80 µV, while AD8602DRZ specifies 1.3 mV. The AD8602ARZ is suitable for precision applications requiring tighter offset tolerance.

Q: Can the TS1852ID operate at 1.8 V supply with the AD8542 series as a substitute?

A: No. The AD8542 series minimum supply voltage is 2.7 V, which exceeds the TS1852ID's 1.8 V minimum. Applications requiring 1.8 V operation must retain the TS1852ID or select alternative devices with lower minimum supply voltage specifications. The AD8532 and AD8602 series also specify 2.7 V minimum supply voltage.

Q: What inventory status should I consider when selecting a substitute part?

A: All substitute parts listed are active products with confirmed current inventory availability. The AD8542ARZ-REEL7 variant maintains the highest inventory level at 23,100 pieces, followed by AD8532ARZ-REEL7 at 26,300 pieces. For long-term supply assurance, active product status combined with high inventory levels provides the greatest availability margin.
