Introduction to LT1790BCS6-3.3#TRPBF

The LT1790BCS6-3.3#TRPBF is a Voltage Reference IC from Linear Technology that is part of their PMIC (Power Management IC) family. This device is specifically designed for providing momentary or DC voltage-regulated source references. It provides selectable voltage outputs from 1.25V to 18V as well as a buffered current source/sink output of up to ±1mA.

Application Field and Working Principle

The LT1790BCS6-3.3#TRPBF is designed for applications that require accurate, stable and low-noise voltage references to help regulate power supply voltages and current. It is ideal for a wide range of applications such as precision analog circuits, audio, communications, instrumentation and medical equipment. The LT1790BCS6-3.3#TRPBF is based on the Bandgap Voltage Reference topology, which is an analog technique that is used to regulate the output of power supply voltages and current. The bandgap regulates the output voltage to a fixed level relative to the reference voltage supplied to the circuit. The device uses a Zener diode to modulate the current of the voltage reference circuit. This creates an output voltage that is linear with temperature and is resistant to line and load variations.The device can be configured in various ways through the combination of different power supplies and external components. There are three different feedback options available: single-ended, differential, and common-mode feedback. The two outputs can be tied together to provide a higher current output or a more precise voltage gain. The LT1790BCS6-3.3#TRPBF also has a low output noise and a high operating temperature range making it suitable for a variety of applications. The device is available in both leaded and lead-free package options.

Conclusion

The LT1790BCS6-3.3#TRPBF is a voltage reference IC designed for applications requiring accurate and stable power supplies. It is based on a bandgap voltage reference topology and supports three feedback configurations for creating precision analog circuits. The device also features a low output noise and a wide operating temperature range. This makes it an ideal choice for a number of applications such as instrumentation, medical equipment, audio, and communications.
