The HI5800 is a monolithic, 12-bit, sampling Analog-toDigital Converter fabricated in the HBC10 BiCMOS process. It is a complete subsystem containing a sample and hold amplifier, voltage reference, two-step subranging A/D, error correction, control logic, and timing generator. The HI5800 is designed for high speed applications where wide bandwidth, accuracy and low distortion are essential.
