LT1999IS8-10#PBF - High Voltage, Bidirectional Current Sense Amplifier

The LT1999IS8-10#PBF from Linear Technology is a high-performance, bidirectional current sense amplifier designed to monitor current in both charging and discharging states of batteries, power supplies, and motor control applications. Its robust design allows for precise current measurement in high voltage systems with a common mode range from -10V to 80V, making it an ideal choice for automotive and industrial environments where high voltage and varying power conditions are common.

With its fixed gain of 10V/V, the LT1999IS8-10#PBF provides a precise, amplified output that is directly proportional to the sensed differential input voltage. This feature simplifies the task of converting the current flowing through a shunt resistor into a measurable voltage, which can then be easily read by an analog-to-digital converter (ADC) for further processing.

The device is housed in a compact 8-lead SOIC package, which offers a space-saving solution without compromising on performance. The LT1999IS8-10#PBF also features a fast response time, making it suitable for detecting overcurrent conditions quickly and reliably, thereby protecting circuits from potential damage.

Key features of the LT1999IS8-10#PBF include its wide operating temperature range of -40°C to 85°C, which ensures reliable operation in extreme conditions. Additionally, its precision over temperature with a maximum input offset voltage of 500µV, and a maximum gain error of 0.8%, guarantees accurate current sensing over a wide range of temperatures.

Furthermore, the LT1999IS8-10#PBF is designed with a low input bias current and a shutdown feature that reduces the quiescent current to 20µA, making it an energy-efficient choice for battery-powered applications. The device is also RoHS compliant, adhering to environmental standards for hazardous substances.

Overall, the LT1999IS8-10#PBF from Linear Technology is a versatile and reliable component for precise current sensing in high voltage applications, offering both accuracy and efficiency in a small form factor.
