Description

The MPT57481 is a 240-channel output, low-power, 5-V, signal source (column) driver for an active matrix LCD panel. This device has a digital-to-analog converter for each output. The MPT57481 utilizes 10 reference voltages for a 64 gray-scale subpixel output. Eight drivers are required for a 640 × 480 color LCD and ten drivers are required for a 800 × 600 color LCD.
