The AN8816SB is a 4ch. driver using the power opera- tional amplifier method. It employs the surface mounting type package superior in radiation characteristics. n Features

• Wide output D-range is available regardless of refer- ence voltage on the system
• Setting of driver input/output gain enabled by external resistance
• 2ch. independently controllable PC (Power Cut) feature built-in
• Thermal shut down circuit (with hysteresis) built-in
• Proper heat of IC controllable by separating the output supply and setting each independently for 2ch.
• Construction of 5V supply enabled by external PNP Tr
• Accessary operational amplifier built-in
• Relatively easy pattern design by separating and con- centrating the input line and output line n Application Actuator for CD/CD-ROM, motor driver AN8816SB 4ch.
