The LT1460BIS8-2.5#TRPBF is a voltage reference from the a family of precision, low-noise voltage references from Linear Technology, commonly referred to as the LT1460 family. This particular device is a ±2.5V, low-noise voltage reference. This reference, along with the other members of the LT1460 family, can be used in a variety of analog and digital applications where the need for a low-noise voltage reference is required.

The LT1460 family of voltage references come in many different configurations, including dual and quad voltage references, as well as in different voltage configurations. The LT1460BIS8-2.5#TRPBF, in particular, is a ±2.5V voltage reference with low noise and a high accuracy of 0.04%. It is designed to operate with a supply voltage of 4.75V to 8.5V and an output current capability of up to 5mA.

In terms of its application field, the LT1460BIS8-2.5#TRPBF is often used in systems where low-noise regulation and precision voltage reference are needed. This includes power management applications such as switched-mode power supplies and battery-powered systems, as well as circuits for medical and instrumentation systems, and for data acquisition and conversion circuits. It can also be used in automotive applications such as voltage regulators, motor controllers, cruise control systems, and temperature sensing circuits.

Also important to consider is how the LT1460BIS8-2.5#TRPBF performs from a technical standpoint. The device features a low-noise ultralow dropout voltage of 0.14V and a high-stability TCV coefficient of 6ppm/°C. This is on top of its low-power operation (maximum 7mA) and wide range of operating temperature (-40 °C to +125 °C).

In terms of its working principle, the LT1460BIS8-2.5#TRPBF is a two-terminal Zener diode voltage reference, meaning it produces a stable voltage reference output from the input voltage. This is accomplished using a Zener diode-based monolithic integrated circuit, which is optimized for low noise and tight regulation. The reference voltage is established by the combination of a series connection of MOS diodes and resistors. An external resistor-capacitor network can be used to achieve higher accuracy and lower noise.

The LT1460BIS8-2.5#TRPBF, like the other members of the LT1460 family, also offers a variety of features that help enhance its performance and extend its usage. These include a rapid-start functionality to reduce turn-on time, an active current limit to protect the die on over-temperature trips,a slew-rate compensation circuit to minimize the output voltage overshoot when compared to other LT1460 devices, and thermal overload protection.

Overall, the LT1460BIS8-2.5#TRPBF is an ideal choice for low-noise, high-accuracy applications that require a 2.5V voltage reference. With its features and low-noise performance, it can be used in a variety of power management, medical, instrumentation, automotive, and data acquisition and conversion applications. Its two-terminal Zener diode voltage reference approach further adds to its effectiveness, allowing for a stable reference output with minimal noise.
