PRODUCT DESCRIPTION  
PRODUCT HIGHLIGHTS  
The AD624 is a high precision, low noise, instrumentation  
amplifier designed primarily for use with low level transducers,  
including load cells, strain gauges and pressure transducers. An  
outstanding combination of low noise, high gain accuracy, low  
gain temperature coefficient and high linearity make the AD624  
ideal for use in high resolution data acquisition systems.  
1. The AD624 offers outstanding noise performance. Input  
noise is typically less than 4 nV/Hz at 1 kHz.  
2. The AD624 is a functionally complete instrumentation am-  
plifier. Pin programmable gains of 1, 100, 200, 500 and 1000  
are provided on the chip. Other gains are achieved through  
the use of a single external resistor.  
The AD624C has an input offset voltage drift of less than  
0.25 µV/°C, output offset voltage drift of less than 10 µV/°C,  
CMRR above 80 dB at unity gain (130 dB at G = 500) and a  
maximum nonlinearity of 0.001% at G = 1. In addition to these  
outstanding dc specifications, the AD624 exhibits superior ac  
performance as well. A 25 MHz gain bandwidth product, 5 V/µs  
slew rate and 15 µs settling time permit the use of the AD624 in  
high speed data acquisition applications.  
3. The offset voltage, offset voltage drift, gain accuracy and gain  
temperature coefficients are guaranteed for all pretrimmed  
gains.  
4. The AD624 provides totally independent input and output  
offset nulling terminals for high precision applications.  
This minimizes the effect of offset voltage in gain ranging  
applications.  
5. A sense terminal is provided to enable the user to minimize  
the errors induced through long leads. A reference terminal is  
also provided to permit level shifting at the output.  
The AD624 does not need any external components for pre-  
trimmed gains of 1, 100, 200, 500 and 1000. Additional gains  
such as 250 and 333 can be programmed within one percent  
accuracy with external jumpers. A single external resistor can  
also be used to set the 624’s gain to any value in the range of 1  
to 10,000.
