... PA98 • PA98A INPUT PROTECTION Although the PA98 can withstand differential voltages up to ±25V, additional external protection is recommended. Since the PA98 is a high speed amplifier, low leakage, low capacitance JFETs connected as diodes are recom- mended (e.g. 2N4416, Q1-Q4 in Figure 1). The differential input voltage will be clamped to ±1.4V. This is sufficient overdrive to produce maximum power bandwidth ...
