VRE210MA

Overview

The VRE210MA is a precision voltage reference providing a +10 V output with ±1.0 mV initial error over the -55°C to +125°C military temperature range. It features an extremely low drift of 1.11 ppm/°C, 6 ppm/1000 hours typical long-term stability, and 3 ppm/V typical line regulation. The device utilizes a proprietary multipoint laser compensation technique for high accuracy and is housed in a hermetic 20-terminal ceramic LCC package.

FAQ

How does the VRE210MA handle ground connection errors?

The device has two ground pins internally connected. Connecting Pin 10 to power supply ground and Pin 9 to a high impedance measurement ground eliminates errors caused by socket contact resistance.

What is the purpose of the TRIM pin?

Pin 11 allows for optional fine adjustment of the output voltage by connecting it to a voltage divider between OUT and GND.
