Multi-Channel Bi-Directional Digital Optocoupler
the input voltage in discrete steps with finite resolution. The quad-channel and bi-directional, ACSL-6410, provides high CMR of 10kV/us and electrical isolation of 2500Vrms between the host system and the data acquisition circuitry and sensors. The power supply is also isolated, usually via a transformer to isolate the AC line voltage from the DC voltages generated to power the data acquisition system.
Benefits
• Higher integration - multi-channel provides small and thin packages for space savings; bi-directional channel facilitates PCB routing
• Wide voltage supply and temperature -provides design flexibility
Description
The ACSL-6xx0 series are optoisolated, multi-channel and bidirectional, high­speed optocouplers. Integration of multiple optocouplers in monolithic form is achiev­ed through patented process technology. These devices provide full duplex and bidirectional isolated data transfer and communication capability in compact surface mount packages. They are available in a 15Mbd speed option, wide supply voltage range and wide temperature range.
The isolated data acquisition system is ideal for digitizing the output of the sensors that operate in hostile environment. The ADC is a 24-bit sigma delta or fast conversion type, converts the analog voltage to a digital number. The digital number represents
Applications
• Fullduplexcommunication
• Isolated line receiver
• Computer-peripheral interfaces
• Microprocessor system interfaces
• Digital isolation forA/D and D/A conversion
• Switching power supply
• Instrumentinput/output isolation
• Ground loopelimination
• Pulse transformer replacement
