Voltage reference devices are used to provide a stable reference voltage for powering and measuring circuits, often for analog and digital converters. The VRE104M is a voltage reference designed for devices in the Point of Load (POL)solution space. A reference voltage is an absolute value applied to circuits in order to accurately measure, compare and control voltages. Voltage references provide an extremely low temperature coefficient and very low output noise. The VRE104M is designed for the Point of Load (POL) application space, which is a way of powering different components in a computing system or a semiconductor device using multiple separate voltage sources spread out across the board.

The VRE104M voltage reference features a low temperature coefficient of 0.07 ppm/°C and a low output noise of 200 nV peak-to-peak. It is capable of providing a temperature-stable reference voltage of 4.096V with a high accuracy of ± 0.25%. Additionally, it has an input voltage range of 4.5V to 5.5V, making it suitable for applications where the input voltage varies. Also, the VRE104M voltage reference can operate with a shifting common mode voltage on the output.

The VRE104M voltage reference contains an internal band gap reference made up of an integrating amplifier, a temperature sensor, and an active compensation. The band gap reference circuit provides a stable reference output with the desired accuracy and very low temperature coefficient. The integrating amplifier, along with the temperature sensor, works to match the output voltage to a reference voltage level. The active temperature compensation is used to further ensure that the output voltage is not affected by temperature variations.

The VRE104M voltage reference also features an internal oscillator and an output buffer to reduce noise. The internal oscillator provides the timing signals needed to match the output voltage to the reference voltage level, while the output buffer is used to provide a low-noise output voltage. In addition, the VRE104M voltage reference increases efficiency by using current-limit technology and an internal power shutoff. This prevents it from using more power than necessary, thus allowing the circuit to operate more efficiently.

The VRE104M is ideal for use in Point of Load (POL) applications, where it can provide a stable low-noise reference voltage. It is also suitable for measurements and controls applications, providing an accurate reference voltage and temperature stability. Additionally, the VRE104M voltage reference is designed with advanced features, making it a suitable choice for high-precision digital and analog circuits. With its low temperature coefficient, high accuracy, low-noise output, and other features, the VRE104M is able to provide an ideal voltage reference for a wide variety of applications.
