The AD684 is a four-channel sample-and-hold amplifier with independent inputs, outputs, and control pins. Its fast acquisition time and low aperture jitter make it the best choice for multiple channel data acquisition systems.
The AD684 is a monolithic quad sample‑and‑hold amplifier designed for high‑speed, high‑accuracy data‑acquisition systems. Each channel has independent inputs, outputs and hold control, with a typical acquisition time of 1 ns and a hold‑settling time of 500 ns.
It is offered in three temperature‑grade versions (J, A, S) and in a 16‑pin Cerdip package. The device consumes about 430 mW of power and features low droop (0.01 µV/µs) and low aperture jitter (75 ps).
| Power Consumption | 430 mW (typical) |
|---|---|
| Operating Temperature Range | J‑grade 0 °C to +70 °C; A‑grade –40 °C to +85 °C; S‑grade –55 °C to +125 °C |
The AD684 is offered in three grades: J‑grade operates from 0 °C to +70 °C, A‑grade from –40 °C to +85 °C, and S‑grade from –55 °C to +125 °C.
