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.
Distortion in the audio band is an extremely low 0.00025%
(112 dB) at a gain of and 0.00035% (109 dB) at a gain of 2
while driving a 600 Ω load
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.
With no external components, the AD8274 can be configured
as a G = 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.
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.
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.
