Its small size and surface mounting capabilities make it a good choice for applications where space is limited.

Working Principle

The LT1790ACS6-4.096#TRMPBF is a voltage reference PMIC that uses a bandgap technology to generate a precise, stable voltage reference. The device acts as an oscillator and generates a square wave at a frequency dictated by the current flowing through a precision resistor. The square wave is then fed into a gain stage, which amplifies it and adjusts it to the desired voltage. The precise voltage is then available as the reference input.The LT1790ACS6-4.096#TRMPBF has a ±0.1% accuracy over a temperature range of -40°C to +85°C and is capable of producing output reference voltages ranging from 1.2V to 3V. The device is designed to switch off when the input voltage drops below 1V so that it does not draw power when not in use. The device is also designed to minimize power consumption while in operation, with an average quiescent current of only 10µA.

Conclusion

The LT1790ACS6-4.096#TRMPBF is a cost-effective, high-performance voltage reference PMIC. It is suitable for a wide range of applications, including microprocessors, DSPs, and analog-to-digital converters. Its low power consumption and wide operating temperature range make it suitable for automotive and aerospace applications. Its high accuracy, low noise, and low output impedance make it suitable for situations where precision and wide output swings are necessary.
