AD580TH

Ad580TH is a precision, thermally-stabilized, low noise, three terminal bandgap voltage reference. It is a special performance voltage reference with low power dissipation, typically 2 mW. It has an initial output voltage accuracy of 2mV and a temperature coefficient of 2ppm/℃. It also offers an extremely long operating lifetime of up to 300 million hours.

The Ad580TH’s output voltage is actively maintained at a precise level by a negative temperature coefficient (NTC) circuit. This NTC circuit is adjusted to make the on-chip NTC equal to the external NTC. This allows the reference voltage to be accurately calibrated during manufacture and provide a more stable reference during use.

The Ad580TH can be used in many applications where precise voltage regulation is desired. It is commonly used as an isolated voltage source, providing precise and stable power in analog and mixed signal circuits. The device can be used in a variety of analog circuits such as switched-capacitor filters, DACs, power management ICs, and A/D converters. Additionally, the Ad580TH’s low noise and low offset helps in reducing the jitter noise and drift of data acquisition systems.

The Ad580TH’s output voltage is stable for up to 6.5V and its temperature coefficient is guaranteed between 0C to +70C. The output voltage is also optimized to minimize sawtooth noise and can maintain a constant voltage with supply voltage variations from 3.2V to 12V. Additionally, the device has excellent short-term stability with a 0.1mV offset drift over the first hour and a 0.9µV/mo offset drift over 1000hrs.

To summarize, the Ad580TH is an accurate, thermally-stabilized, low noise, three terminal bandgap voltage reference with low power dissipation and accurate output voltage accuracy. The device is ideal for applications that require precise voltage regulation, and its low noise, low offset, and low supply noise helps to improve data acquisition systems. The Ad580TH is a good choice for DC voltage regulation in analog, mixed signal, and power management circuits.
