PRODUCT HIGHLIGHTS
1. Fast acquisition time (1
μ
s) and low aperture jitter (75 ps)
make the AD684 the best choice for multiple channel data
acquisition systems.
2. Monolithic construction insures excellent interchannel
matching in terms of timing and accuracy, as well as high
reliability.
3. Independent inputs, outputs and sample-and-hold controls
allow user flexibility in system architecture.
4. Low droop (0.01
μ
V/
μ
s) and internally compensated hold
mode error results in superior system accuracy.
5. The AD684’s fast settling time and low output impedance
make it ideal for driving high speed analog to digital
converters such as the AD578, AD674, AD7572 and the
AD7672.
6. The AD684 is available in versions compliant with MIL-
STD-883. Refer to the Analog Devices

or current AD684/883B data sheet for detailed
specifications.
PRODUCT DESCRIPTION
The AD684 is a monolithic quad sample-and-hold amplifier
(SHA). It 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 1
μ
s and retain the held value with a droop rate of less
than 0.01
μ
V/
μ
s. 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 5 mA and
incorporates output short circuit protection.
The AD684 is specified for three temperature ranges. The J
grade device is specified for operation from 0 to +70
°
C, the A
grade from –40
°
C to +85
°
C and the S grade from –55
°
C to
+125
°
C.
