Low-cost, Accurate Voltage/Current/Resistance Reference

摘要

Most of the parts are SMDs and all but one have widely-spaced connections, making them easy to solder. The only slightly tricky one is IC1 but it really isn't that hard. It's best to solder the SMDs first, starting with IC1, before finishing with the through-hole parts. Refer to the appropriate overlay diagram - Fig.3 for outputs of up to 2.5 V and Fig.4 for higher voltages.
