ADR45xx Voltage References

Voltage references combine ultra-low noise, high accuracy, and high value for precision applications from Analog Devices

Image of Analog Devices' ADR45xx Voltage ReferencesADI presents a series of voltage references offering the industry’s best combination of noise performance, initial output voltage accuracy, low temperature coefficient (TC), and excellent long-term stability at unmatched price points. The ADR45xx series of voltage references are specifically suited for high-resolution data converters and precision applications in data acquisition systems, instrumentation, process control, and automotive battery monitoring.

With low frequency noise of 0.5 ppm, maximum temperature coefficient of 2 ppm/°C over the full operating temperature range of -40°C to +125°C, and a typical long-term drift of only 25 ppm/1khr, the ADR45xx series of voltage references provide high accuracy over time and temperature variations critical for many precision applications. This performance is achieved with a maximum quiescent current of 950 µA, making the devices ideal for portable and budget sensitive designs.

Features
  • Initial output voltage error: ±0.02 percent (max.)
  • Operating temperature: -40°C to +125°C
  • Output current: +10 mA source/-10 mA sink
  • Low dropout voltage: 300 mV at 2 mA (VOUT ≥ 3 V)
  • Maximum TC: 2 ppm/°C
  • Low quiescent current: 950 µA (max.)
  • Input voltage range: 3 V to 15 V
  • Output noise (0.1 Hz to 10 Hz): < 1 µVP-P at 2.048 VOUT (typ.)
