 +====== TGGALVO / 4 Channel DAC card ======
 +<WRAP center round important 60%>
 +CAUTION! On startup the card outputs will swing to -10Volts briefly. This may damage instruments that aren't designed to handle negative input. ​
 +TGGALVO card is a variant of the MicroMirror card(TGMM4) capable of running the same(or other) firmware. Instead of the MEMS drive electronics,​ it buffers, amplifies and outputs the DAC signals. ​
 +[{{ ::​tggalvo.jpg?​direct&​300 |TGGALVO card}}]
 +===== Overview =====
 +  * TGGALVO has four 12 bit DAC onboard. ​
 +  * Has TTL pins connected to TG-1000'​s backplane, so it can sync with other cards in the TG-1000 controller? ​
 +  * Multiple DAC output voltage modes are available. Like 0V to 2.048V, 0V to 4.096V, 0V to 10.24V, -1.024V to 1.024V, -2.048V to 2.048V, -5.128V to 5.128V and -10.24V to 10.24V(default). Set with the [[commands:​pm|PM command]]
 +  * Can output a maximum of 10ma per channel. ​
 +  * 100 ohm resistor in series at BNC output
 +  * 5th order programmable Bessel filter is present on each DAC channel to filter out DAC aliasing effects. ​
 +  * Can be configured to drive a Galvo amplifier, Piezo amplifier and other devices that can accept an analog voltage input. ​
 +  * Compatible with Micro-Manager and diSPIM plugin. ​
