ADT5116TA www.ad-tech.co.kr General Description The ADT5115T/ADT5116TA is a transmitter IC for digital audio interface, e.g., DVD player, digital TV. This IC is packaged with LED in one fiber optic module. This supports the high speed data transmission near to 16Mbps and direct connections to modulation IC for digital audio equipment. The ADT5116T/ADT5116TA is very small to be suitable for any types of fiber transmitting module. Features • • • • • Low Jitter Output High Speed Data Transmission to 16Mbps Operating Voltage : 2.7V~5.5V Direct connectable to TTL or High Speed CMOS Logic LED Driving Current : ADT5116T(typ. 6mA), ADT5116TA(typ. 3mA) Application Fiber Optic Module for Digital Audio Equipment Absolute Maximum Ratings (Ta=25℃) Parameter Symbol Ratings Unit Supply Voltage Vcc -0.5 ~ 7.0 volts Input Voltage Vin -0.5 ~ Vcc+0.5 volts Operating Temperature Topr -20 ~ 70 ℃ Storage Temperature Tstg -30 ~ 80 ℃ * Stress above those listed under Absolute Maximum Ratings may cause permanent damage of device. This is stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for longer periods may affect device reliability. During overload conditions (VIN>Vcc or VIN<GND), those voltage on Vcc pins with respect to ground must not exceed the values defined by the absolute maximum ratings.
