GENERAL DESCRIPTION  
The AD8274 is a difference amplifier that delivers excellent ac  
and dc performance. Built on Analog Devices, Inc., proprietary  
iPolar® process and laser-trimmed resistors, AD8274 achieves a  
breakthrough in distortion vs. current consumption and has  
excellent gain drift, gain accuracy, and CMRR.  
With no external components, the AD8274 can be configured  
as a G = ½ or G = 2 difference amplifier. For single-ended  
applications that need high gain stability or low distortion  
performance, the AD8274 can also be configured for several  
gains ranging from −2 to +3.  
Distortion in the audio band is an extremely low 0.00025%  
(112 dB) at a gain of ½ and 0.00035% (109 dB) at a gain of 2  
while driving a 600 Ω load  
The excellent distortion and dc performance of the AD8274,  
along with its high slew rate and bandwidth, make it an excellent  
ADC driver. Because of the part’s high output drive, it also  
makes a very good cable driver.  
With supply voltages up to 18 V (+36 V single supply), the  
AD8274 is well suited for measuring large industrial signals.  
Additionally, the part’s resistor divider architecture allows it to  
measure voltages beyond the supplies.  
The AD8274 only requires 2.6 mA maximum supply current. It  
is specified over the industrial temperature range of −40°C to  
+85°C and is fully RoHS compliant. For the dual version, see the  
AD8273 data sheet.
