Product Overview

The AD684JQ is a monolithic quad Sample-and-Hold Amplifier (SHA) features four complete sampling channels, each controlled by an independent hold command. Each SHA is complete with an internal hold capacitor. The high accuracy SHA channels are self-contained and require no external components or adjustments. The AD684 is manufactured on a BiMOS process which provides a merger of high performance bipolar circuitry and low power CMOS logic. The AD684 is ideal for high performance, multichannel data acquisition systems. Each SHA channel can acquire a signal in less than 1ms and retain the held value with a droop rate of less than 0.01mV/ms. Excellent linearity and AC performance make the AD684 an ideal front end for high speed 12- and 14-bit ADCs. The AD684 has a self-correcting architecture that minimizes hold mode errors and insures accuracy over temperature. Each channel of the AD684 is capable of sourcing 5mA and incorporates output short-circuit protection.
  • Four matched sample-and-hold amplifiers
  • Independent inputs, outputs and control pins
  • Internal hold capacitors
  • 1μs Maximum acquisition time to 0.01%
  • 0.01μV/μs Low droop rate
  • 75ps Maximum aperture jitter
  • 430mW Low power dissipation

Applications

Test & Measurement; Defence, Military & Aerospace
ESD sensitive device, electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection.
