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 performance for applications which require both precision and high speed performance. Military version (/883) data sheets are available upon request.

HA-5160 Application Information
Power Supply Decoupling
Although not absolutely necessary, it is recommended that all power supply lines be decoupled with 0.01F ceramic capacitors to ground. Decoupling capacitors should be located as near to the amplifier terminals as possible. 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 (100) be connected in series with the output of the device and inside the feedback loop.
Stability
The phase margin of the HA-5160 will be improved by connecting a small capacitor (>10pF) between the output
Power Supply Minimum
The absolute supply minimum is 6V and the safe level is 7V.
