Precision op amp offers industry's best noise performance

The first in a new series of high-voltage, low-noise, zero-drift, precision operational amplifiers that reduce system noise, cost, board space, and development time by providing on-chip electro-magnetic interference (EMI) filtering and eliminating the need for calibration circuitry - the dual-channel ADA4522-2 op amp has been unveiled by Analog Devices. The device operates within a supply voltage range of 4.5V to 55V and exhibits noise performance that is at least 35 percent better than its closest competitor, says the company. The ADA4522-2 provides the ease-of-use of a precision op amp with the ultra-low offset and drift of a zero-drift op map. The ADA4522-2 is suitable for a wide range of applications, including current sensing in electronic loads, power supplies and motor control and offset correction in composite amplifiers used in instrumentation and other applications.
