HA-5160

Data Sheet September 1998 File Number 2911.3

100MHz, JFET Input, High Slew Rate,
Uncompensated, Operational Amplifier

The HA-5160 is a wideband, uncompensated, operational
amplifier with FET/Bipolar technologies and Dielectric
Isolation. This monolithic amplifier features superior high
frequency capabilities further enhanced by precision laser
trimming of the input stage to provide excellent input
characteristics. This device has excellent phase margin at a
closed loop gain of 10 without external compensation.

The HA-5160 offers a number of important advantages over
similar FET input op amps from other manufacturers. In
addition to superior bandwidth and settling characteristics,
the Intersil devices have nearly constant slew rate,
bandwidth, and settling characteristics over the operating
temperature range. This provides the user predictable
performance in applications where settling time, full power
bandwidth, closed loop bandwidth, or phase shift is critical.
Note also that Intersil specified all parameters at ambient
(rather than junction) temperature to provide the designer
meaningful data to predict actual operating performance.

Complementing the HA-5160’s predictable and excellent
dynamic characteristics are very low input offset voltage, very
low input bias current, and a very high input impedance. This
ideal combination of features make these amplifiers most
suitable for precision, high speed, data acquisition system
designs and for a wide variety of signal conditioning
applications. The HA-5160 provides excellent perf ormance f or
applications which require both precision and high speed
performance.

Application Information

HA-5160

Power Supply Decoupling

Although not absolutely necessary, it is recommended that
all power supply lines be decoupled with 0.01µF ceramic
capacitors to ground. Decoupling capacitors should be
located as near to the amplifier terminals as possible.

Stability

The phase margin of the HA-5160 will be improved by
connecting a small capacitor (>10pF) between the output

and the inverting input of the device This small capacitor
compensates for the input capacitance of the FET.

Capacitive Loads

When driving large capacitive loads (>100pF), it is
suggested that a small resistor (≈100Ω) be connected in
series with the output of the device and inside the feedback
loop.

Power Supply Minimum

The absolute supply minimum is ±6V and the saf e le vel is ±7V .
