20MHz, High Slew Rate, Uncompensated,
High Input Impedance, Operational
Amplifiers
HA-2520/2522/2525 comprise a series of operational amplifiers
delivering an unsurpassed combination of specifications for
slew rate, bandwidth and settling time. 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.

Typical Application
Inverting Unity Gain Circuit
Figure 6 shows a Compensation Circuit for an inverting unity
gain amplifier. 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.
