The SPT9101 is capable of sampling at speeds up to 125 MSPS with resolutions ranging from 8 to 12 bits. Trim programmable internal hold and compensation capacitors provide for optimized input bandwidth and slew rate versus noise performance. The performance of this device makes it an excellent front end driver for a wide range of ADCs on the market today. Significant improvements in dynamic performance can be achieved by using this device ahead of virtually all ADCs that do not have an internal track-and-hold. The SPT9101 is offered in 20-lead SOIC and LCC packages over the industrial temperature range and in die form. Contact the factory for military and /833 package options.
