SAMPLE/HOLD AMPLIFIER  
FEATURES  
DESCRIPTION  
12-BIT THROUGHPUT ACCURACY  
LESS THAN 10µs ACQUISITION TIME  
WIDEBAND NOISE LESS THAN 20µVrms  
RELIABLE MONOLITHIC CONSTRUCTION  
1010INPUT RESISTANCE  
The SHC298 and SHC298A are high-performance  
monolithic sample/hold amplifiers featuring high DC  
accuracy with fast acquisition times and a low droop  
rate. Dynamic performance and holding performance  
can be optimized with proper selection of the external  
holding capacitor. With a 1000pF holding capacitor,  
12-bit accuracy can be achieved with a 6µs acquisition  
time. Droop rates less than 5mV/min are possible with  
a 1µF holding capacitor.  
TTL-CMOS-COMPATIBLE LOGIC INPUT  
These sample/holds will operate over a wide supply  
voltage ranging from ±5V to ±18V with very little  
change in performance. A separate Offset Adjust pin  
is used to adjust the offset in either the Sample on the  
Hold modes. The fully differential logic inputs have  
low input current, and are compatible with TTL, 5V  
CMOS, and CMOS logic families.

30kΩ  
The SHC298AM is available in a hermetically sealed  
8-pin TO-99 package and is specified over a tempera-  
ture range from –25°C to +85°C. The SHC298JP and  
SHC298JU are 8-pin plastic DIP and SOIC packaged  
parts specified over 0°C to +70°C.

Logic  
The SHC298AJP, specified over 0°C to +70°C, is  
available in an 8-pin plastic DIP. The SHC298A grade  
features improved gain and offset error, improved drift  
over temperature, and faster acquisition time.

Mode Control (S/H) Input  
The SHC298 family is a price-performance bargain. It  
is well suited for use with several 12-bit A/D convert-  
ers in data acquisition systems, data distribution  
systems, and analog delay circuits.
