STMicroelectronics has launched the TSB192, a dual operational amplifier built for precise performance across a wide supply range of 4 V to 36 V. It is aimed at applications that need accurate analog signal processing under changing conditions, offering low offset voltage, minimal drift with temperature, and reliable frequency behavior.
The amplifier delivers a typical input offset of 20 µV, with a maximum of 30 µV over its full temperature range. Its low drift of 100 nV/°C helps maintain accuracy without requiring extra calibration in precision designs. Unlike many precision amplifiers limited to lower voltages, the TSB192 maintains consistent performance across a broader supply range, making it adaptable for industrial, automotive, medical, and consumer systems.
Efficiency is also a focus, with each channel drawing up to 1.9 mA, making it suitable for power-sensitive and battery-operated devices. Its rail-to-rail output allows full use of the supply voltage, improving signal range and measurement accuracy.
With an 8 MHz gain-bandwidth and a 5 V/µs slew rate, the TSB192 supports stable operation across various frequencies. Low input noise of 11 nV/√Hz further enhances performance in sensitive applications. This makes it well-suited for use in sensors, bridge circuits, strain gauges, and precision filtering where clean, linear amplification is essential.
The device is designed for dependable operation in systems such as temperature monitoring, weighing equipment, medical devices, and industrial instruments. It works across a wide temperature span from −40 °C to 125 °C and includes ESD protection up to 4 kV, improving durability in demanding environments.
The TSB192 is offered in SO-8 and MiniSO-8 packages and is already in mass production, with an automotive-grade version expected in 2026.
