Maxim 749 Series SMD Digitally Adjustable LCD Bias Supplies
- Maxim MAX749ESA+, This device is a negative-output inverting power controller that generates an LCD-bias contrast voltage from its +2V to +6V inputs in order to drive either a PNP transistor or a P-channel MOSFET. Full-scale output voltage can be scaled, using an external resistor & the internal DAC to over -100V & the output is digitally adjustable in 64 steps by the internal DAC as well as a PWM signal or a potentiometer. Suitable for a wide range of applications, including: communication systems, h&-held computing devices, portble data-collection terminals, etc. Maxim MAX749ESA+ Linear IC SO8 LCD Adjustable Bias Supply
