LF6197 - 160ns Monolithic Sample-and-Hold Amplifier

The LF6197 is a monolithic sample-and-hold (S H) amplifier that uses a proprietary ‘‘current-multiplexed sample-andhold’’ technique to offer extremely high speed while maintaining 12 bits or higher accuracy The device is built using National’s advanced junction-isolated VIPTM (Vertically Integrated
