DC Tests: VIN = 2.5VDC AC Tests: Output = 130VPP (35V - 165V) at 1MHz LM2459 Symbol Parameter Conditions Units Min Typical Max ICC Supply Current No AC Input Signal, No Output Load 6 12 mA IBB Bias Current 4 7 mA VOUT, 1 DC Output Voltage No AC Input Signal, VIN = 2.5VDC 99 104 109 VDC VOUT, 2 DC Output Voltage No AC Input Signal, VIN = 1.2VDC 165 170 175 VDC AV DC Voltage Gain No AC Input Signal -48 −51 -54 LE Linearity Error See(1), No AC Input Signal 5 % tR Rise Time See(2), 10% to 90% 26 ns tF Fall Time See(2), 90% to 10% 30 ns OS Overshoot See(2) 5 % (1) Linearity Error is the variation in DC gain from VIN = 1.1V to VIN = 3.8V. (2) Input from signal generator: tr, tf < 1 ns. AC TEST CIRCUIT Note: 10pF load includes parasitic capacitance. Figure 3. Test Circuit Figure 3 shows a typical test circuit for evaluation of the LM2459. This circuit is designed to allow testing of the LM2459 in a 50 Ω environment without the use of an expensive FET probe. The two 4990Ω resistors form a 400:1 divider with the 50 Ω resistor and the oscilloscope. A test point is included for easy use of an oscilloscope probe.The compensation capacitor is used to compensate the network to achieve a flat frequency response.
