TSV7723

The TSV7723 is a low-power, single-channel operational amplifier manufactured by STMicroelectronics, designed for precision analog signal conditioning in space-constrained and power-sensitive applications. It operates from a single supply voltage ranging from 1.8 V to 5.5 V, making it suitable for battery-powered systems and portable electronics. The device features a wide gain-bandwidth product of 1.2 MHz, ensuring stable performance across a broad frequency range while maintaining low noise and high linearity. This amplifier offers rail-to-rail input and output swing, allowing maximum dynamic range utilization even at low supply voltages. Its low quiescent current—typically just 40 µA per channel—makes it ideal for energy-efficient designs where minimizing power consumption is critical. The TSV7723 also provides excellent DC accuracy, with a typical offset voltage of 1 mV and a maximum input bias current of 10 nA, enabling precise amplification of small signals without introducing significant errors. Built on ST’s advanced CMOS process technology, the TSV7723 delivers high reliability and robustness against EMI and transient disturbances. It includes internal frequency compensation to ensure stability in both inverting and non-inverting configurations, simplifying circuit design and reducing the need for external components. The package is available in a compact SC-70 (SOT-23-5) format, which supports high-density PCB layouts and facilitates automated assembly processes. Common applications include sensor signal conditioning in industrial automation, medical instrumentation, and consumer electronics such as smartphones and wearables. It is well-suited for interfacing with thermocouples, strain gauges, and other low-level sensors that require amplification with minimal power draw. Additionally, its compatibility with digital-to-analog converter (DAC) drivers and analog front-end circuits makes it a versatile choice in mixed-signal systems. The TSV7723 is fully specified over an extended temperature range from -40°C to +125°C, enhancing its suitability for harsh environments like automotive and industrial control systems. With no need for external trimming or calibration, it reduces design complexity and cost while improving system longevity. This amplifier is particularly effective in applications demanding long-term stability, low drift, and consistent performance under varying load and environmental conditions.
