PRODUCT DESCRIPTION  
PRODUCT HIGHLIGHTS  
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.  
1. Fast acquisition time (1 µs) 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.  
The AD684 is ideal for high performance, multichannel data  
acquisition systems. Each SHA channel can acquire a signal in  
less than 1 µs and retain the held value with a droop rate of less  
than 0.01 µV/µs. Excellent linearity and ac performance make  
the AD684 an ideal front end for high speed 12- and 14-bit  
ADCs.  
4. Low droop (0.01 µV/µs) 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.  
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.  
6. The AD684 is available in versions compliant with MIL-  
STD-883. Refer to the Analog Devices Military Products  
Databook or current AD684/883B data sheet for detailed  
specifications.  
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.
