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 PNP) and BI-FETTM process technologies The LF6197 acquires a 10V step input to within g 0 01% in 160 ns and has 10 mV hold step error when going from sample to hold mode The input offset voltage in the sample mode is typically 3 mV Even at extremely fast acquisition speeds no compromises are made in the droop rate which is 0 6 mV ms When configured for unity gain the DC gain error is 0 03% The feedthrough attenuation in the hold mode is 83 dB at DC and 77 dB at 100 kHz The LF6197 can be externally configured for either inverting or non-inverting gains thus offering additional flexibility to the user The device includes an internal 10 pF hold capacitor |
