Product Summary
The AD783AQ is a high speed, monolithic sample-and-hold amplifier (SHA). It offers a typical acquisition time of 250 ns to 0.01%. The AD783AQ is specified and tested for hold mode total harmonic distortion with input frequencies up to 100 kHz. The AD783AQ is configured as a unity gain amplifier and uses a patented self-correcting architecture that minimizes hold mode errors and ensures accuracy over temperature. It is self-contained and requires no external components or adjustments. The AD783AQ retains the held value with a droop rate of 0.02μV/μs. Excellent linearity and hold mode dc and dynamic performance make the AD783AQ ideal for high speed 12- and 14-bit analog-to-digital converters.
