It utilizes an advanced VLSI 1.2 µm CMOS process providing 30-MHz sampling rates at 8 bits. Different digital output multiplex formats are selectable on chip via several control inputs, patible to inputs of all Siemens Featureboxes, Siemens TV-SAM, and CCIR 656 output format. The ADCs have no missing codes over the full operating temperature range of 0 to + 70 °C. Operation is from + 5 V DC-power supply.
