OBPRODUCT DESCRIPTION
The AD346 is a high speed (2J.lSto 0.01%), adiustmem free
Ssample-and-hold amplifier designed for high throughput rate
Odata acquisition applications. The fast acquisition time (211s(0
0.01%) and low aperture jitter (400ps) make it suitable for use
Lwith fast AID converters to digitize signals up to 97kHz.
EThe AD346 is complete with an internal hold capacitor and it
incorporates a compensation network which minimizes the sample
Tto hold charge offset. The AD346 is also laser trimmed to eliminate
Ethe need for external trimming potentiometers.
PRODUCT HIGHLIGHTS
1. The AD346 is an improved second source for other sample
and holds of the same pin configuration.
2. The AD346 provides separate analog and digital grounds,
thus improving the device's immunity to ground and switching
transients.
3. The droop rate is only O.SmV/ms so that it may be used in
slower high accuracy systems without the loss of accuracy.
4. The fast acquisition time and low aperture make it suitable
for very high speed data acquisition systems.
Typical applications for the AD346 include sampled data systems,
D/A deglitchers, peak hold functions, strobcd measurement
systems and simultaneous sampling converter systems.
PIN CONFIGURATION
The device is available in tWo versions: the "J" specified for
operation over the 0 to + 700C commercial temperature range
and the "S" specified over the extended temperature range,
- 55°C to + 125°C.
