The MAX749CSA is a digitally adjustable LCD bias supply IC designed by Analog Devices. It generates negative LCD-bias contrast voltages from 2V to 6V inputs. The output voltage is digitally adjustable in 64 equal steps via an internal DAC, offering flexible control. It requires only seven small surface-mount components for a complete supply.
Key features include a low quiescent current of 60µA maximum, which reduces to under 15µA in shutdown mode. The device operates with a high switching frequency up to 500kHz, minimizing the size of external components. It is suitable for applications requiring compact power solutions.
This IC is available in an 8-SOIC package, designed for surface mounting. Its applications include notebook computers, palmtop computers, personal digital assistants, and portable data-collection terminals where efficient and adjustable bias voltage generation is critical.
