PRODUCT DESCRIPTION  
PRODUCT HIGHLIGHTS  
The AD625 is a precision instrumentation amplifier specifically  
designed to fulfill two major areas of application: 1) Circuits re-  
quiring nonstandard gains (i.e., gains not easily achievable with  
devices such as the AD524 and AD624). 2) Circuits requiring a  
low cost, precision software programmable gain amplifier.  
1. The AD625 affords up to 16-bit precision for user selected  
fixed gains from 1 to 10,000. Any gain in this range can be  
programmed by 3 external resistors.  
2. A 12-bit software programmable gain amplifier can be config-  
ured using the AD625, a CMOS multiplexer and a resistor  
network. Unlike previous instrumentation amplifier designs,  
the ON resistance of a CMOS switch does not affect the gain  
accuracy.  
For low noise, high CMRR, and low drift the AD625JN is the  
most cost effective instrumentation amplifier solution available.  
An additional three resistors allow the user to set any gain from  
1 to 10,000. The error contribution of the AD625JN is less than  
0.05% gain error and under 5 ppm/°C gain TC; performance  
limitations are primarily determined by the external resistors.  
Common-mode rejection is independent of the feedback resistor  
matching.  
3. The gain accuracy and gain temperature coefficient of the  
amplifier circuit are primarily dependent on the user selected  
external resistors.  
4. The AD625 provides totally independent input and output  
offset nulling terminals for high precision applications. This  
minimizes the effects of offset voltage in gain-ranging  
applications.  
A software programmable gain amplifier (SPGA) can be config-  
ured with the addition of a CMOS multiplexer (or other switch  
network), and a suitable resistor network. Because the ON  
resistance of the switches is removed from the signal path, an  
AD625 based SPGA will deliver 12-bit precision, and can be  
programmed for any set of gains between 1 and 10,000, with  
completely user selected gain steps.  
5. The proprietary design of the AD625 provides input voltage  
noise of 4 nV/Hz at 1 kHz.  
6. External resistor matching is not required to maintain high  
common-mode rejection.  
For the highest precision the AD625C offers an input offset  
voltage drift of less than 0.25 µV/°C, output offset drift below  
15 µV/°C, and a maximum nonlinearity of 0.001% at G = 1. All  
grades exhibit excellent ac performance; a 25 MHz gain band-  
width product, 5 V/µs slew rate and 15 µs settling time.  
The AD625 is available in three accuracy grades (A, B, C) for  
industrial (–40°C to +85°C) temperature range, two grades (J,  
K) for commercial (0°C to +70°C) temperature range, and one  
(S) grade rated over the extended (–55°C to +125°C) tempera-  
ture range.
