The AD780CR Voltage Reference is an integrated precision microcircuit designed to provide a stabilized d.c. reference voltage which is substantially independent of temperature and supply voltage variations. It is available in 9V and 10V voltage, with a temperature coefficient of 0.2mV/°C and a maximum 0.2% maximum drift tolerance over 10°C~85°C temperature. It can be used in a variety of applications that require a voltage reference for monitoring or maintaining system performance over time, including battery-operated systems, instrumentation, A/D and D/A converters, data acquisition systems, computer systems and medical systems.
The key to the AD780CR’s accuracy and temperature independence is its patented internal regulator, which produces a stable d.c. voltage at its output terminal. This output voltage is capacitively coupled and buffered by an on-chip amplifier to produce a low-impedance (sinking) reference. The AD780CR’s regulator also has an internal bandgap for temperature stabilization and the device’s logic inputs are TTL compatible for low power levels. The low power requirements allow the device to operate on low voltage supplies, making it ideal for battery-powered applications.
The AD780CR is a monolithic integrated circuit capable of providing a precision stable voltage reference and has a wide range of applications. It can be employed as a current regulator, as a voltage source for A/D converters and other analog circuits, for temperature and pressure measurement, for motor speed control, for light levels and lamps, for instrument and container closure detection, for current monitoring and for power regulation. This device can also be used with shunt regulators to provide voltage reference for µProcessors and µOurlorometers. The on-chip precision reference can very efficiently replace trickle current or stacking references, providing cost savings and increased accuracy.
The working principle of the AD780CR is based on the fact that the internal bandgap produced at the junction of two different transistor types has a precise temperature-independent voltage that is generally accepted as 1.220±0.005 volts. This voltage is typically referred to as a “bandgap voltage reference.”
The bandgap voltage is first generated using an integrated output stage that generates a stable reference voltage relative to the current supply voltage. This reference voltage is then buffered by an on-chip amplifier and precision rectified to produce a precise d.c. voltage output that is independent of the circuit temperature and supply voltage. This output voltage is then regulated by an internal voltage regulator so that it remains constant throughout a temperature range of 0°C to +85°C. The internal regulator also provides the flexibility of a wide input supply voltage range from 4.5V to 16.0V.
In conclusion, the AD780CR Voltage Reference is a precision microcircuit designed to provide a stabilized d.c. reference voltage which is substantially independent of both temperature and supply voltage variations. It is used in a variety of applications requiring a voltage reference for monitoring or maintaining system performance over time, including battery operated systems, instrumentation, A/D and D/A converters, data acquisition systems, computer systems and medical systems. The AD780CR’s internal bandgap voltage reference and on-chip amplifier are what make it so accurate, with a temperature coefficient of 0.2mV/°C and a maximum 0.2% maximum drift tolerance over the 10°C to 85°C temperature range.
