Introduction

VRE 100MA is a 3-terminal precision voltage reference designed for the digital-audio and broadcast audio sectors. Providing a stable, accurate and low-drift reference voltage for synchronous and asynchronous signals, the VRE 100MA is a reliable and efficient tool for generating signals that can be used in digital audio systems, communications systems, and professional audio environments. The VRE 100MA is useful for applications that require a stable voltage reference and have a budget constraint.

Function and Working Principle

VRE 100MA has a wide range of input voltages (1.8V to 5V) and can provide an accurately regulated output voltage of up to 500mV. The VRE 100MA uses a precision integrated circuit (IC) to provide accurate and stable voltage references. The design uses an internal zener diode, a reference voltage transistor, an opamp, and several passive components. The IC provides very accurate voltage references for the optimal performance of the circuit. A resistive divider is usually connected across the output terminals to reduce the output voltage according to the required specification.The VRE 100MA supplies a stable voltage reference of up to 500 mV with a minimum load current of 0.1 mA. The design also allows for a wide range of temperature coefficients between -20 ppm/°C and +150 ppm/°C. This temperature coefficient range means that the VRE 100MA can maintain its general output voltage stability under temperature fluctuations. A Schottky diode is also included to protect the circuit against reverse EMF and spikes.

Application

VRE 100MA is ideal for use in audio systems, communications systems, and professional audio environments. It is an excellent choice for use in analog-to-digital converters (ADC) to provide a stable voltage reference as well as multi-stage amplifiers. The VRE 100MA can be used in audio amplitude control applications such as volume or fade applications, as well as in frequency control circuits for tuning and equalization. The VRE 100MA can also be used in AC to DC power converters and DC to DC switching power supplies. It is an excellent choice for battery-operated systems as it can maintain an accurate voltage reference even under varying supply voltage and temperature. The VRE 100MA can also be used in level-shifting circuits and analog applications such as peak detectors.

Conclusion

In conclusion, VRE 100MA is a robust, accurate, and low-drift voltage reference designed for digital-audio and broadcast audio applications. It can withstand harsh environments and has a wide range of input voltage and good temperature coefficient range. The VRE 100MA is an excellent choice for a variety of applications including ADC, LED drivers, portable devices and more.
