Abstract :
A monolithic high-speed sample-and-hold amplifier is described which has an acquisition time of 1.5 /spl mu/s to 0.001% for a 10-V step and an aperture uncertainty of less than 0.5 ns. Distortion is 0.001% over the audio band, while in an A/D and D/A converter loop a signal-to-noise ratio better than 90 dB is measured. Chip size is 1.5/spl times/2.5 mm/SUP 2/.
