AD8274

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational ection of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

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 as excellent gain drift, gain accuracy, and CMRR.

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 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 = ½ or G = 2 difference amplifier. For single-ended pplications that need high gain stability or low distortion performance, the AD8274 can also be configured for several ains 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 xcellent 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 −40to +85 and is fully RoHS compliant. For the dual version, see the AD8273 data sheet.
