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 ½ 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 = 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.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.

The AD8275 is a G=0.2 difference amplifier that can be used totranslate +/-10V signals to a +4V level. It solves the problemtypically encountered in industrial and instrumentation where+/-10V signals must be interfaced to a single supply 4V or 5VADC. The AD8275 interfaces the two signal levels, simplifyingdesign.The AD8275 has fast settling time of 450 ns and low distortion,making it suitable for driving medium speed successive approximation(SAR) ADCs. Its wide input voltage range and rail-torailoutputs make it an easy to use building block. Single-supplyoperation reduces the power consumption of the amplifier andhelps to protect the ADC from overdrive conditions. Internal, matched, precision laser-trimmed resistors ensurelow gain error, low gain drift of 1 ppm/°C (maximum), andhigh common-mode rejection of 80 dB. Low offset and lowoffset drift, combined with its fast settling time, make theAD8275 suitable for a variety of data acquisition applicationswhere accurate and quick capture is required. The AD8275 can be used as an analog front end, or it can followbuffers to level translate high voltages to a voltage range acceptedby the ADC. In addition, the AD8275 can be configured fordifferential outputs if used with a differential ADC. The AD8275 is available in a space-saving, 8-lead MSOP and is specified for performance over the −40°C to +85°C temperature range.ApplicationsLevel TranslatorADC DriverInstrumentation Amplifier Building BlockAutomated test equipment
