Monolithic Linear IC
LA5316M
Variable Divided Voltage Generator for LCD
Overview
The LA5316M is a variable divided voltage generator IC
for multiple drive of LCD matrix.
Features
• Power supply for variable bias LCD drive (1/5 to 1/13
bias available by on-chip resistances).
• 5 operational amplifiers to deliver 5 voltage outputs.
• Low current drain (1.5mA max).
• Miniflat package.
• On-chip variable voltage regulator for VREF.
