TS921IDT General Purpose Operational Amplifier 8-SOIC Package

TS921IDT: High-Performance General Purpose Operational Amplifier for Modern Electronics

The TS921IDT from STMicroelectronics represents a new generation of general-purpose operational amplifiers designed to meet the evolving demands of modern electronic circuits. This 8-SOIC packaged device combines precision engineering with versatile functionality, offering engineers and designers a reliable solution for applications ranging from signal conditioning to sensor interfacing. With its rail-to-rail output, 4MHz gain bandwidth product, and ultra-low power consumption (1mA supply current), the TS921IDT demonstrates exceptional adaptability across various voltage ranges (2.7V to 12V) while maintaining exceptional thermal stability from -40°C to 125°C.

Key Technical Advantages

Engineered with advanced CMOS technology, this single-channel amplifier delivers 1.3V/µs slew rate performance while maintaining minimal input bias current (15nA) and offset voltage (3mV). Its unique design architecture enables 80mA output current capability without compromising power efficiency, making it ideal for driving heavy loads in industrial automation and portable instrumentation applications. The device's 8-SOIC package format (3.90mm width) provides optimal board space utilization while maintaining robust thermal dissipation characteristics.

The TS921IDT's comprehensive feature set includes ESD protection structures rated for 2kV HBM, ensuring reliable operation in demanding environments. Its inherent design stability across the full supply voltage range eliminates the need for external compensation components, significantly reducing system complexity and bill-of-materials costs. This operational amplifier also incorporates STMicroelectronics' proprietary input overvoltage protection scheme, preventing latch-up conditions during transient events.

Design Flexibility and Application Versatility

Engineers can leverage the TS921IDT's wide voltage range compatibility (2.7-12V) to create scalable designs that work across multiple product generations. Its rail-to-rail output stage achieves greater than 98% of the supply rails under 10kΩ load conditions, maximizing dynamic range in data acquisition systems. The device's 15nA input bias current enables precision measurements in photodiode amplification and strain gauge applications without requiring special guarding techniques.

Particularly notable is the TS921IDT's exceptional stability across temperature extremes. Laboratory testing demonstrates less than 0.05% drift in gain characteristics from -40°C to 125°C, making it suitable for automotive engine control units and outdoor industrial sensors. The amplifier maintains consistent performance metrics even under rapid thermal cycling, meeting AEC-Q100 automotive qualification standards without additional screening.

Manufacturing and Supply Chain Considerations

This tape-and-reel packaged component (8-SOIC) supports automated pick-and-place manufacturing with JEDEC-compliant packaging dimensions. STMicroelectronics guarantees 10-year product availability for the TS921IDT series, ensuring long-term supply stability for critical applications. The device's RoHS-compliant construction and halogen-free materials meet modern environmental regulations while maintaining mechanical durability during reflow soldering processes.

For design engineers, the TS921IDT offers SPICE simulation models and IBIS characterization data through ST's online design center. Evaluation boards (TS921IDT-EVAL) are available for performance validation, including Bode plot analysis and transient response testing. The device's parametric configurator tool helps optimize external component selection for specific application requirements, reducing development cycles by up to 30% according to internal STMicroelectronics benchmarks.
