ADR4530ARZ-R7

超低噪声，高精度 Ultralow Noise, High Accuracy

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.
