• Application Field of LT1790BCS6-4.096#TRMPBF

LT1790BCS6-4.096#TRMPBF is a high performance, low noise adjustable shunt voltage reference. It is a type of PMIC - Voltage Reference, which is designed to provide a precision voltage reference to voltage monitors, controllers, digital-to-analog converters, sensor interfaces, power supplies and other applications. The LT1790BCS6-4.096#TRMPBF also features low quiescent current (Iq) and low current noise, making it suitable for use in mobile and battery-powered products.The LT1790BCS6-4.096#TRMPBF has an operating temperature range from -40°C to 125°C and an operating voltage range from 4.5V to 16V. It is available in a 6-pin SOT-23 package. Its integrated oscillator allows for precise operation over the specified temperature range. This reference also offers a wide range of voltage settings from 0.8V to 6V with a ±0.03% accuracy, making it ideal for use in high-precision applications. In addition, the LT1790BCS6-4.096#TRMPBF features a low ESR of 0.5Ω, which helps reduce power dissipation and improve compliance in noisy environments. The device also has a low quiescent current of 130μA and a low current noise of 7.5μA.

• Working Principle Of LT1790BCS6-4.096#TRMPBF

The LT1790BCS6-4.096#TRMPBF works by sectioning an external voltage reference into two parts - an upper reference voltage and a lower reference voltage. An internal resistor network, called the Reference Divider Network, is then used to compare the two reference voltages and produce an output voltage that is proportional to the factory set reference voltage.The Reference Divider Network consists of two series resistors, R1 and R2, and a parallel resistor, RP. The voltage across these resistors is equal to the reference voltage, VREF. The value of the output voltage, VOUT, is proportional to the ratio of R1 and R2. This ratio is determined by the factory set value of RP.The LT1790BCS6-4.096#TRMPBF is equipped with an oscillator which constantly recalibrates the output voltage by measuring the voltage difference between the upper reference voltage and the lower reference voltage. The resulting voltage can be adjusted by externally adjusting RP.In addition, the LT1790BCS6-4.096#TRMPBF is also capable of self-protecting against under and over-voltage conditions. If the input voltage exceeds the specified maximum, the reference voltage output is limited to prevent damage to the device. Similarly, if the input voltage drops below the minimum, the reference voltage output is limited to maintain the accuracy of the device.
