About the AD8253
Designed for data acquisition systems, automatic test equipment and biomedical instruments requiring fast, accurate measurement with robust signal conditioning over large voltage ranges, the AD8253 digitally programmable instrumentation amplifier is able to reach gains of 1,000 while offering dc precision and ac bandwidth unmatched by other in-amps or discrete solutions on the market. A large gain setting allows small signals, such as those from sensors, to be amplified to drive an ADC.

The AD8253 is digitally programmable with gain settings of 1, 10, 100 and 1000, letting users adjust gain even after the devices are designed into the system. Operating from ±5 V to ±15 V, it achieves 10 MHz bandwidth and 0.5-microsecond settling time to 0.01 percent. The input offset drift of 1.2 microvolt/degree C and gain drift of 10 ppm/degree C is the lowest of any programmable gain in-amp. Manufactured using Analog Devices’ iCMOS™ (industrial CMOS) process technology, the AD8253 draws just 4 mA of quiescent current and is available in 10-lead MSOP (mini small-outline plastic) packages.

The AD8253 is the newest member of digitally programmable instrumentation amplifiers from ADI, complementing the AD8250 and AD8251. In addition, the AD8253 is tailored to operate with high-performance ADCs, such as ADI’s AD7621, AD7671, AD7674, AD7677, AD7678, AD7679, AD7685, AD7612 and AD7946 and AD7947 PulSAR® high-resolution SAR ADCs and ADI’s ADR431 and ADR435 voltage references.

Pricing and Availability
The AD8253 is sampling now in a 10-lead MSOP package with production quantities available in October 2007. It is specified over the –40 C degree to +85 C degree temperature range, making it an excellent solution for applications where size and packaging density are important considerations. The AD8253 is priced at $4.95 per unit in 1,000-unit quantities.

About iCMOS
iCMOS (industrial-CMOS) is Analog Devices’ modular manufacturing process combining high-voltage devices with submicron CMOS (complementary metal-oxide semiconductor) and complementary bipolar technologies. It enables the development of a wide range of high-performance analog ICs capable of 30-V operation in a small footprint, which no other generation of high-voltage parts has been able to achieve. Unlike analog ICs using conventional CMOS processes, iCMOS components can tolerate high supply voltages, while providing increased performance, dramatically lower power consumption, and reduced package size.

About Analog Devices
Innovation, performance, and excellence are the cultural pillars on which Analog Devices has built one of the longest standing, highest growth companies within the technology sector. Acknowledged industry-wide as the world leader in data conversion and signal conditioning technology, Analog Devices serves over 60,000 customers, representing virtually all types of electronic equipment. Celebrating over 40 years as a leading global manufacturer of high-performance integrated circuits used in analog and digital signal processing applications, Analog Devices is headquartered in Norwood, Massachusetts, with design and manufacturing facilities throughout the world. Analog Devices' common stock is listed on the New York Stock Exchange under the ticker “ADI” and is included in the S&P 500 Index.
