HA-2529
September 1998 File Number 2895.3
20MHz, High Input Impedance, High Slew Rate Operational Amplifier
The HA-2529 is a monolithic operational amplifier which typifies excellence of design. With a design based on years of experience coupled with the reliable dielectric isolation process, this amplifier provides an outstanding combination of DC and AC parameters at closed loop gains greater than 3. The HA-2529 offers 150V/s slew rate and fast settling time (200ns), while consuming a mere 6mA of quiescent current, making this amplifier ideal for video circuitry and data acquisition designs. With 20MHz gain bandwidth combined with 7.5kV/V open loop gain, the HA-2529 is an ideal component for demanding signal conditioning designs. This device provides 30mA output current drive with an output voltage swing of 10V making it suited for pulse amplifier and RF amplifier components. The HA-2529 will upgrade output current, slew rate, offset voltage drift and offset current drift in systems presently using the HA-2520/22/25 or EHA-2520/22/25.

HA-2529 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/s; 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.
