Speed and precision makes amp difference
High-speed, low-distortion and precision dual-channel difference amplifiers designed for applications that require extremely fast and precise measurement.
New from Analog Devices, the AD8270 and AD8273 are high-speed, low-distortion and precision dual-channel difference amplifiers designed for applications that require extremely fast and precise measurement without compromising signal fidelity, such as avionics, industrial process controls and high-performance audio equipment The 10MHz AD8270 and 12MHz AD8273 are three times faster than competing parts

A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
In addition, the AD8270 features a 30V/us slew rate that is nearly three times better than the nearest competing difference amplifier, and the 25V/us slew rate of the AD8273 is more than 1.5x higher than other competing amplifiers.
This AC performance is complemented by DC precision, best-in-class SNR (signal-to-noise ration) and an 86dB common mode rejection ratio that is 12dB higher than competing devices.
These figures combine to give designers the ac and dc performance needed for rapid, error-free signal processing, which is critical for semiconductor test equipment, programmable logic controllers, power monitors and other high-speed multichannel systems.
The AD8270, available in a 4 x 4mm package, is significantly smaller than other competing dual-channel difference amplifiers.
The AD8273 is available in a 54mm square package that is pin- and function-compatible with competing difference amplifiers, which allows designers to substitute the higher-performing part without reconfiguring board layout.
Both the AD8270 and AD8273 feature internal gain-setting resistors that allow the design engineer to set gain with no external components.
The AD8270 and AD8273 dual difference amplifiers are sampling now and will be available in full production quantities in October 2007.
The AD8270 comes in a 16-lead LFCSP (lead-frame chip-scale package) and is priced at US $1.99 per unit in 1000-piece quantities.
The AD8273 dual difference amplifier is available in a 14-lead SOIC (small-outline integrated circuit) package and is priced at US $1.65 per unit in 1000-piece quantities.
