PMIC - Voltage Reference: LT1461BCS8-3.3#PBF Application Field and Working Principle

The LT1461BCS8-3.3#PBF is a programmable voltage reference IC that provides a regulated voltage reference in the range of 3.3V. It is a versatile component, capable of being used in a variety of different applications including power management, voltage regulation, and analog to digital conversion. This versatile IC can be used in different voltage reference, linear and switching applications with an output voltage range between 0.5V and 3.3V. It is also ideal for Ethernet, HD-SDI, Can Bus, and RS-485 interfaces, and for providing a low current bias for a wide range of sensors.

The LT1461BCS8-3.3#PBF voltage reference IC has very few external components, meaning it is easy to design with and requires less space on the board. It requires two external capacitors - one for the VREF and one for the Enable input. The VREF capacitor is used to bypass noise from the output and the Enable input capacitor is used to filter noise from the Enable input pin. The IC draws very little power as most of the power is internal and comes from an on-board voltage regulator, meaning that it can be used in battery-powered and other low-power applications.

The LT1461BCS8-3.3#PBF’s reference output is highly stable over temperature and process variations. This is achieved by using the proprietary low temperature-dependent μA741 output amplifier. The amplifier automatically self-calibrates the reference output voltage, adjusting it over temperature and process ranges. This ensures a stable, accurate output voltage over the entire operating temperature range.

The LT1461BCS8-3.3#PBF also has a range of safety and protection built-in, meaning it is suitable for use in harsh and potentially hazardous environments. The IC has over-current, over-temperature, and over-voltage protection, as well as an adjustable shutdown and power-good signals. This makes it an ideal choice for use in battery-powered applications.

In sum, the LT1461BCS8-3.3#PBF is a highly reliable, cost-effective voltage reference IC suitable for a wide range of voltage reference, linear, and switching applications. It provides a stable, accurate output voltage over a wide temperature and process range with low power consumption and minimum external components. It is also highly safe and protected due to its adjustable shutdown and power-good signals, making it ideal for use in potentially hazardous environments and battery-powered applications.
