56 / 65 page TL05x, TL05xA, TL05xY ENHANCED-JFET LOW-OFFSET OPERATIONAL AMPLIFIERS SLOS178 – FEBRUARY 1997 56 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 APPLICATION INFORMATION phase meter The phase meter in Figure 84 produces an output voltage of 10 mV per degree of phase delay between the two input signals VA and VB. The reference signal VA must be the same frequency as VB. The TLC3702 comparators (U1) convert these two input sine waves into ±5-V square waves. Then R1 and R4 provide level shifting prior to the SN74HC109 dual J-K flip flops. Flip-flop U2B is connected as a toggle flip-flop and generates a square wave at half the frequency of VB. Flip-flop U2A also produces a square wave at half the input frequency. The pulse duration of U2A varies from zero to half the period, where zero corresponds to zero phase delay between VA and VB and half the period corresponds to VB lagging VA by 360 degrees. The output pulse from U2A causes the TLC4066 (U3) switch to charge the TL05x (U4) integrator capacitors C1 and C2. As the phase delay approaches 360 degrees, the output of U4A approximates a square wave and U2A has an output of almost 2.5 V. U4B acts as a noninverting amplifier with a gain of 1.44 in order to scale the 0- to 2.5-V integrator output to a 0- to 3.6-V output range. R8 and R10 provide output gain and zero-level calibration. This circuit operates over a 100-Hz to 10-kHz frequency range. + – + – + 5 V R2 100 k Ω R1 100 k Ω U1A VA S 1J C1 U2A 1K R NC U2B 2K R3 VB U1B R6 10 k Ω R7 10 k Ω + 5 V S 2J C1 R NC 100 k Ω R4 100 k Ω U3 R5 C1 10 k Ω 0.016 µF C2 0.016 µF U4A U4B VO R9 20 k Ω R8 Gain 50 k Ω + 5 V R10 10 k Ω Zero – 5 V NOTE A: U1 = TLC3702; VCC ± = ±5 V U2 = SN74HC109 U3 = TLC4066 U4, U5 = TL05x; VCC ± = ±5 V Figure 84.
