Analog Devices Inc. AD780ANZ Precision Voltage Reference

The AD780ANZ is a high-precision, low-noise, 2.5 V/3.0 V voltage reference from the esteemed manufacturer Analog Devices Inc. This versatile component is housed in a robust 8-lead PDIP (Plastic Dual In-line Package), ensuring reliable performance and ease of integration into a wide range of electronic systems.

With its exceptional accuracy and temperature stability, the AD780ANZ stands out as a superior choice for precision data conversion in high-end applications. It offers a temperature coefficient of just 10 ppm/°C over the full industrial temperature range, making it an ideal component for circumstances where consistent performance is crucial, regardless of environmental temperature fluctuations.

The AD780ANZ can be configured to provide a fixed 2.5V or 3.0V output, catering to the needs of various circuits and devices. Its low output noise of just 8 µV p-p/V, which is measured over the 0.1 Hz to 10 Hz band, ensures a clean and stable reference voltage, a critical feature for high-resolution analog-to-digital (A/D) and digital-to-analog (D/A) conversions, precision instrumentation, and data acquisition systems.

Another significant advantage of the AD780ANZ is its low dropout voltage, typically 60 mV at full load. This allows the voltage reference to maintain its accuracy even with minimal headroom above the output voltage, thus enhancing efficiency and flexibility in power supply design. The device also features a trimmable output, which allows for fine-tuning of the voltage reference to achieve an even higher degree of precision if necessary.

Power supply rejection is excellent, rated at 60 dB for the AD780ANZ, which means that variations in the supply voltage have minimal impact on the output voltage. This characteristic is particularly important in battery-powered devices, where supply voltage may vary over time.

In summary, the AD780ANZ from Analog Devices Inc. is a top-tier voltage reference that combines high precision, low noise, and excellent thermal stability. It is an essential building block for applications demanding the utmost accuracy and consistency in voltage referencing, such as medical devices, precision measurement equipment, and high-end industrial controls.
