These dielectrically isolated amplifiers are controlled at close loop gains greater than 3 without external compensation. In addition, these high performance components also provide low offset current and high input impedance. 120V/µs slew rate and 200ns (0.2%) settling time of these amplifiers make them ideal components for pulse amplification and data acquisition designs. These devices are valuable components for RF and video circuitry requiring up to 20MHz gain bandwidth and 2MHz power bandwidth. For accurate signal conditioning designs the HA-2520/2522/2525’s superior dynamic specifications are complemented by 10nA offset current, 100MΩ input impedance and offset trim capability. MIL-STD-883 product and data sheets are available upon request. Ordering Information PART NUMBER (BRAND) TEMP. RANGE (oC) PACKAGE PKG. NO.

The circuit was tested for functionality with supply voltages from ±4V to ±15V, and the performance as tested was: Slew Rate ≈ 120V/µs; Bandwidth ≈ 10MHz; and Settling Time (0.1%) ≈ 500ns. Figure 7 illustrates the amplifier’s frequency response, and it is important to note that capacitance at pin 8 must be minimized for maximum bandwidth.
