Background

Voltage references are devices used in digital electronics, analog electronics, and power management to supply a stable reference voltage over varying conditions. This is often used as a reference source for linear regulators, operational amplifiers, A/D and D/A converters, and other similar electronic circuits. Voltage references come in various shapes and sizes and have a wide range of applications, from battery management to isolated power supplies.

Application Field

The LT6656AIDC-3#TRMPBF precision voltage reference is designed to provide an accurate and stable 3.6V output over varying conditions, such as current and temperature variations. It is designed to operate in a wide temperature range (from -40 to +125C) and is suitable for use in industrial systems, automotive and avionics applications, and precision devices.

The LT6656AIDC-3#TRMPBF can be used in a variety of applications, such as precision voltage and current sources, bandgap references, DAC references, analog to digital converters, and transimpedance amplifiers. It is also suitable for use in battery management circuits, isolated power supplies, and voltage and current measurement devices.

Working Principle

The LT6656AIDC-3#TRMPBF is a precision voltage reference integrated circuit based on Linear Technology\'s proprietary PTAT (Proportional to Absolute Temperature) reference cell. This reference cell is designed to accurately set and hold the accurate 3.6V output voltage by compensating for any current, temperature, and time variations in the VOREF (Voltage Output Reference) terminal.

The LT6656AIDC-3#TRMPBF utilizes a combination of current source and bandgap references to maintain the VOREF terminal at 3.6V. It has a wide temperature operating range (-40 to +125C), and it can provide good accuracy and stability even at higher temperatures. The IC is also equipped with an optional shutdown mode, allowing the user to reduce power consumption when the device is not in use.
