High-precision dual operational amplifiers support a wide 4V to 36V operating voltage range

STMicroelectronics has released the TSB192, a dual operational amplifier designed for high-precision performance across a broad operating-voltage spectrum. This technology targets signal-conditioning networks in industrial, automotive, healthcare, and consumer electronics. By combining low offset voltage with a wide supply range, the device serves as a solution for engineers seeking to minimize compensation circuitry in complex measurement systems.

Enhanced Precision and Thermal Stability
The TSB192 is characterized by a maximum offset voltage of 20µV and a temperature drift of 100nV/°C. While high-accuracy operational amplifiers typically require low-voltage supplies, this device maintains its precision—including a 30µV maximum offset across its full temperature range—while supporting supply voltages from 4V to 36V. This technical architecture allows the device to maintain linearity in analog integrators and measurement circuitry for medical instrumentation, electronic scales, and temperature detectors. The integration of rail-to-rail outputs further maximizes dynamic range for these high-sensitivity applications.

Dynamic Performance for Industrial Instrumentation
For high-frequency applications, the amplifier provides an 8MHz gain-bandwidth and a 5V/µs slew rate. These parameters, coupled with an input noise of 11nV/√Hz, are designed to reduce distortion in precision active filters and amplifiers used for strain gauges, bridges, and transducers. Operational efficiency is supported by a current draw of 1.9mA per channel, which aids in extending the battery life of portable diagnostic equipment.

Availability and Automotive Standards
The TSB192 is engineered for robust environments, operating between -40°C and 125°C with Electrostatic Discharge (ESD) tolerance up to 4kV Human Body Model (HBM). The product is currently available in SO-8 and MiniSO-8 packages. Following the initial release on April 20, 2026, in Geneva, Switzerland, an automotive-grade version is scheduled for availability later in the year to meet specific sectoral reliability standards.
