Ultralow Noise XFET® 4.5V Voltage Reference w/Current Sink and Source Capability
Rochester Electronics is the only authorized source of Analog Devices' products that have previously been discontinued or have become obsolete. Product availability should be checked directly with Rochester Electronics.
The XFET references operate at lower current (800 µA) and supply headroom (2 V) than buried Zener references. Buried Zener references require more than 5 V headroom for operations. The ADR43x XFET references are the only low noise solutions for 5 V systems.
The ADR43x family has the capability to source up to 30 mA of output current and sink up to 20 mA. It also comes with a trim terminal to adjust the output voltage over a 0.5% range without compromising performance.
The ADR43x is available in 8-lead MSOP and narrow SOIC packages. All versions are specified over the extended industrial temperature range of −40°C to +125°C.
