Data Sheet August 1999 File Number

100MHz, Single and Dual Low Noise, Precision Operational Amplifier
The HCA10009 is a high performance dielectrically isolated, op amp, featuring precision DC characteristics while providing excellent AC characteristics. Designed for audio, video, and other demanding applications, noise (3.4nV/Hz at 1kHz), total harmonic distortion (<0.005%), and DC errors are kept to a minimum. The precision performance is shown by low offset voltage (0.3mV), low bias currents (40nA), low offset currents (15nA), and high open loop gain (128dB). The combination of these excellent DC characteristics with the fast settling time (0.4s) make the HCA10009 ideally suited for precision signal conditioning. The unique design of the HCA10009 gives it outstanding AC characteristics not normally associated with precision op amps, high unity gain bandwidth (35MHz) and high slew rate (25V/s). Other key specifications include high CMRR (95dB) and high PSRR (100dB). The combination of these specifications will allow the HCA10009 to be used in RF signal conditioning as well as video amplifiers.

HCA10009 Application Information
Operation at Various Supply Voltages
The HCA10009 operates over a wide range of supply voltages with little variation in performance. The supplies may be varied from 5V to 15V. See Typical Performance Curves for variations in supply current, slew rate and output voltage swing.
Saturation Recovery
When an op amp is over driven, output devices can saturate and sometimes take a long time to recover. By clamping the input, output saturation can be avoided. If output saturation can not be avoided, the maximum recovery time when overdriven into the positive rail is 10.6s. When driven into the negative rail the maximum recovery time is 3.8s.
Offset Adjustment
The following diagram shows the offset voltage adjustment configuration for the HCA10009. By moving the potentiometer wiper towards pin 8 (+BAL), the op amps output voltage will increase; towards pin 1 (-BAL) decreases the output voltage. A 20k trim pot will allow an offset voltage adjustment of about 10mV.
Input Protection
The HCA10009 has built in back-to-back protection diodes which limit the maximum allowable differential input voltage to approximately 5V. If the HCA10009 will be used in circuits where the maximum differential voltage may be exceeded, then current limiting resistors must be used. The input current should be limited to a maximum of 10mA.

PC Board Layout Guidelines
When designing with the HCA10009, good high frequency (RF) techniques should be used when building a PC board. Use of ground plane is recommended. Power supply decoupling is very important. A 0.01F to 0.1F high quality ceramic capacitor at each power supply pin with a 2.2F to 10F tantalum close by will provide excellent decoupling. Chip capacitors produce the best results due to ease of placement next to the op amp and basically no lead inductance. If leaded capacitors are used, the leads should be kept as short as possible to minimize lead inductance.
-15V
Capacitive Loading Considerations
When driving capacitive loads >80pF, a small resistor, 50 to 100, should be connected in series with the output and inside the feedback loop.
