The supply voltage is high, typically at 20-48V, with peaks up to 120 V and strong fluctuations. PREMA ASICs offer power management with integrated regulators or step up converters to provide voltages for example 3.3V or 5V for external components like microprocessors. Sensor interfaces can be integrated for photo diodes, pressure and temperature sensors. Precision amplifiers or transimpedance amplifiers with low noise, small input bias currents and small offsets are available for integration. Drivers for LED and relays can be integrated. If high output currents are necessary, an internal protection against excess temperature or for current limitation can be designed into the ASIC. Beside of these analog blocks digital circuits are required for a simple event control of signals as well as for the more complex communication between the ASIC and microprocessor via SPI interface.   PDF
