LTC1258CMS8-3 MicroPower Voltage Reference

The LTC1258CMS8-3 from Linear Technology is a high-precision, low-power voltage reference designed to provide a stable and accurate reference voltage for a wide array of applications. This device is particularly well-suited for battery-powered systems, data acquisition systems, and portable instrumentation, where energy efficiency and space constraints are of paramount importance.

With a typical output voltage of 3V, the LTC1258CMS8-3 ensures consistent performance with a low temperature coefficient, making it reliable over a broad range of operating conditions. The device is characterized by its minimal power requirements, drawing a mere 50μA of quiescent current, which helps to prolong battery life in portable applications.

The LTC1258CMS8-3 comes in a compact MSOP-8 package, which is ideal for systems where space is at a premium. Its small footprint does not compromise on performance, offering a tight initial accuracy of ±0.2% and a guaranteed temperature coefficient of only 30ppm/°C max over the full operating temperature range of –40°C to 85°C.

One of the key features of this voltage reference is its low dropout performance. The LTC1258CMS8-3 can operate with a supply voltage that is just 50mV above the output voltage, providing excellent flexibility in system design. Additionally, the device features a low output noise of only 20μVP-P (0.1Hz to 10Hz), which is critical in precision analog circuits.

The LTC1258CMS8-3 also includes a shutdown feature, which reduces the supply current to less than 1μA when the reference is not in use, further conserving power in systems that require intermittent operation. This makes it an excellent choice for power-sensitive applications such as handheld meters, medical devices, and remote sensors.

In conclusion, the LTC1258CMS8-3 from Linear Technology is a robust, micro-power voltage reference that offers high accuracy, low power consumption, and a compact package. Its performance and features make it an excellent choice for designers looking to enhance the stability and efficiency of their electronic systems.
