Ultra-Low-Noise, High-Accuracy 4.096V Voltage Reference
Manufactured by:

Product Details

The ADR45xx series of devices are high precision, low power, low noise voltage references, featuring ± 0.02% maximum initial error, excellent temperature stability and low output noise.

This family of voltage references employs a new core topology for high accuracy, while offering industry-leading temperature stability and noise performance. The devices’ low thermally induced output voltage hysteresis and low long-term output voltage drift also improve system accuracy over time and temperature variations.

A maximum operating current of 950 μA and a low dropout voltage (300 mV max) allow the device to be used in portable equipment.

ADR45xx series references are available in a wide range of output voltages, in an SOIC package, all of which are specified over the extended industrial temperature range of -40°C to +125 °C.

APPLICATIONS

  • Precision data acquisition systems
  • High-resolution data converters
  • High-precision measurement devices
  • Industrial instrumentation
  • Medical devices
  • Automotive battery monitoring

Very reliable product with a good price/quality ratio
In its price range, the ADR4540 is perhaps the most reliable and best documented voltage reference. Well suited for cost sensitive application, we've used it as a Vref for 12 bit ADC with excellent results. Recommended.
