TSV781

The TSV781 is a high-performance, low-power operational amplifier manufactured by STMicroelectronics, designed for precision analog signal processing in compact and energy-sensitive applications. It features a wide supply voltage range from 2.0 V to 5.5 V, enabling versatile integration across various power domains—from battery-operated devices to systems powered by standard logic supplies. This device offers a gain-bandwidth product of 1.3 MHz, making it suitable for moderate-speed signal conditioning tasks such as filtering, amplification, and buffering. Its low input offset voltage of typically 1 mV ensures accurate signal reproduction, while the low quiescent current of just 220 µA per amplifier channel contributes to extended battery life in portable electronics. The TSV781 also provides a high open-loop gain of up to 100 dB, enhancing stability and linearity in feedback configurations. One of its key advantages is the rail-to-rail input and output capability, allowing full utilization of the supply voltage range without signal clipping, which is particularly beneficial in single-supply systems. Additionally, it exhibits excellent common-mode rejection ratio (CMRR) and power-supply rejection ratio (PSRR), minimizing noise and interference from external sources—critical in sensitive measurement and sensor interface circuits. Packaged in a space-saving SOT23-5 form factor, the TSV781 is ideal for applications where board real estate is limited, such as wearable devices, IoT sensors, and handheld instruments. It operates reliably over a wide temperature range from –40°C to +125°C, ensuring robust performance in harsh environments like automotive and industrial control systems. The device supports both inverting and non-inverting configurations, offering flexibility in circuit design. Its internal compensation ensures stable operation without requiring external components, simplifying layout and reducing component count. Furthermore, the TSV781 is fully compatible with CMOS and TTL logic levels, facilitating seamless interfacing with digital controllers and microprocessors. These characteristics make the TSV781 well-suited for use in data acquisition systems, medical instrumentation, consumer electronics, and industrial automation, where accuracy, low power consumption, and small footprint are essential requirements.
