STMicroelectronics TS922IPT Dual Operational Amplifier

STMicroelectronics TS922IPT: High-Performance Dual Op-Amp for Automotive Applications

The STMicroelectronics TS922IPT is a dual general-purpose operational amplifier engineered for automotive and industrial applications requiring precision, reliability, and robust performance. This 8-TSSOP packaged IC combines rail-to-rail output swing capabilities with a 4 MHz gain-bandwidth product, making it ideal for signal conditioning, sensor interfacing, and control systems in harsh environments.

Key Features and Technical Specifications

Designed to meet the stringent requirements of the automotive industry, the TS922IPT operates across a wide temperature range (-40°C to 125°C) while maintaining consistent performance. Its 2.7V to 12V supply voltage range provides flexibility for both low-voltage and standard-voltage systems. The amplifier's 1.3V/µs slew rate ensures accurate reproduction of high-frequency signals, while the 15 nA input bias current and 3 mV input offset voltage deliver exceptional precision in measurement applications.

Automotive-Grade Reliability

Qualified under the AEC-Q100 automotive standard, this IC demonstrates exceptional durability in vehicle systems. Its surface-mount 8-TSSOP package (4.40mm width) enables compact PCB layouts while maintaining mechanical stability in vibration-prone environments. The device's rail-to-rail output stage maximizes dynamic range in single-supply configurations, particularly valuable for automotive sensor interfaces and battery-powered systems.

Performance Characteristics

With its 2.7-12V operating range, the TS922IPT supports both modern low-voltage microcontrollers and traditional 5V/12V automotive systems. The 80 mA output current capability per channel allows direct driving of various loads without additional buffer stages. The 4 MHz gain-bandwidth product enables stable operation at high closed-loop gains, making it suitable for precision amplification in motor control and instrumentation circuits.

Design Flexibility and Applications

This dual amplifier finds applications in automotive electronics including engine control units, body electronics, and infotainment systems. Its precision characteristics benefit industrial control systems, medical instruments, and test equipment requiring accurate signal processing. The TS922IPT's low input bias current and offset voltage make it particularly suitable for photodiode amplification, strain gauge interfaces, and other low-level signal conditioning tasks.
