Dual Rail TL431 High Precision Voltage Reference Modules

Now available from PMD Way is this versatile range of dual-rail voltage reference modules built around the popular TL431.

Dual rail means that you can have both positive and negative reference voltage with respect to GND, for example for use with amplifiers - however you can also use the modules simply for voltage and GND.

You can select your required reference voltage using the options menu. 

All boards measure 19 x 13 x 2.8mm, PCB pads have 0.1"/2.54mm pin spacing.
