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.
Using the added cost-efficiencies of its patented DigiTrim trimming process, the AD8661 is available at a highly competitive price point.
The AD8661 is ideal for industrial and instrumentation applications, such as process control, motor control, power-line filtering, point-of-load sensing, and amplification for pressure, strain, and temperature, that require a wide dynamic operating voltage range.
Designed for both single- and dual-supply operation, it is also is well-suited for medical equipment, communications infrastructure, automotive and consumer audio applications.

"With the introduction of the AD8661, Analog Devices is addressing the need of high-voltage electronics equipment with a standard rail-to-rail device capable of accuracy and high performance," said Steve Sockolov, product line director for precision amplifiers, Analog Devices "While other op amps may claim to support higher voltage levels, none have the ability to combine dual-supply, high-voltage operation with the low noise, low offset voltage, low voltage drift, high bandwidth, small package size and competitive price point of the AD8661." About the AD8661 As its newest member, the AD8661 is the first device in Analog Devices' family of industry-leading DigiTrim precision op amps designed specifically for applications requiring operating voltages in the range of 5 V to 16 V (+/- 8 V).
The AD8661 also is the first in a series of competitively priced operational amplifiers that will be manufactured on Analog Devices' iCMOS industrial process technology.
Dual and quad iCMOS op amps are expected in 2005.
The AD8661 features low offset voltage of 75uV (max) and low noise at 10nV/Hz.
The amplifier also reduces input bias currents of 1 pA (max) by a factor of two to four over the closest competing products which is required by devices like high-impedance photodiodes used in opto-electronic applications.
The AD8661 features rail-to-rail output operating voltages from 60mV to 4.85 V for 5-V supplies and "7.97 V to 7.95 V for +/- 8-V supplies.
These tight specifications result in the best possible dynamic range, and allow developers to simplify their signal conditioning designs.
The wider voltage range allows designers to pair their operational amplifiers with high-performance analogue-to-digital converters (ADCs) and digital-to-analogue converters (DACs), such as those offered by Analog Devices.
