If the application calls for the input to sink current there w ill be approxim ately an additional 1 m V of output offset voltage for each 3 m A of current. Sink current should be lim ited to 1 0 0 m A m ax to avoid choke burnout. F or higher supply voltages, up to ±1 5 volts, the positive supply pin m ust include a series Average pow er detection is obtained at pow er levels below approxim ately –1 3 dBm . F or best pulse response the supply pins should be bypassed w ith an additional 1 .0 µF capacitor. The unit contains 0 .0 1 µF internal capacitors. 0.01 TO 4.0 GHz ANALOG DETECTOR DAC4101 Typical Values @ +2 5 °C DAC4101 Single Pow er Supply Standard Size TO -8 Package DAC4101 * 50 -O hm source im pedance, 2 K Ω||50 pF output load, +5 Vdc. † Pin = –1 5 dBm . ^ Vout = 1 0 0 m V. ^^ 3 dB N F , 1 M H z Bandw idth. ‡ 50 % RF to 1 0 or 90 % Video.
