20MHz, High Input Impedance,
High Slew Rate Operational Amplifier
Features
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.

• High Input Impedance . . . . . . . . . . . . . . . . . . . . . . 130MΩ
The HA-2529 offers 150V/µs 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.
• Low Offset Current . . . . . . . . . . . . . . . . . . . . . . . . . . . 5nA
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.

GAIN (dB)
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.
