5 / 12 page 5 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 10.6 µs. When driven into the negative rail the maximum recovery time is 3.8 µs. Input Protection The HA-5221 has built in back-to-back protection diodes which limit the maximum allowable differential input voltage to approximately 5V. If the HA-5221 is 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 HA-5221, 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 0.01 µF to 0.1µF high quality ceramic capacitor at each power supply pin with a 2.2 µF to 10 µF 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. + RLIMIT RLIMIT VOUT 2 3 6 ∆VIN Typical Performance Curves VS = ±15V, TA = 25oC FIGURE 5.
