The HS-9008RH design differs substantially from most other available Flash Converters as it employs fully differential analog input sampling networks and amplifiers, as well as regenerative, offset nulled (error correcting) comparators. These circuit techniques improve noise performance and render the circuit much less sensitive to process and radiation induced device parametric shifts. Outstanding integral and differential linearity error is achieved through the use of a metal film resistor network which exhibits >10-bit linearity without trim. As a result of these innovations, the device operates with a single fixed reference supply as opposed to the multiple, adjustable references used in similar devices.
