seriously disabled Posted October 11, 2009 Posted October 11, 2009 What do these symbols mean in electronics? [math]V_{DDH}[/math] [math]V_{DDL}[/math] [math]V_{SSH}[/math] [math]V_{SSL}[/math]
Klaynos Posted October 11, 2009 Posted October 11, 2009 Some context would be useful, it could be just about anything.
seriously disabled Posted October 11, 2009 Author Posted October 11, 2009 Some context would be useful, it could be just about anything. This is in the context of liquid crystal display drivers.
Klaynos Posted October 11, 2009 Posted October 11, 2009 I've never seen them in a LC context and without knowing more couldn't even guess at what they mean.
seriously disabled Posted October 11, 2009 Author Posted October 11, 2009 I think it means: VDDH = voltage drain drain high VDDL = voltage drain drain low VSSH = voltage source source high VSSL = voltage source source low
SH3RL0CK Posted October 12, 2009 Posted October 12, 2009 Perhaps reading the manufacturers datasheet for the LCD driver would help? Really when you have an IC with perhaps dozens of connections to the circuit, these could mean anything.
