    The error is positive if it is in phase with the reference and neg-
    ative if it is out of phase with the reference.
    The e output can swing ±10 V min with respect to ground when
    the voltage level of the ±15 V power supplies are 15 V. The out-
    put level range changes proportionally with the power supply
    level.
    INTERNAL DC REFERENCE VOLTAGE (V, PIN 1)
    This internal voltage is not required externally for normal opera-
    tion of the converter. It is used as the internal dc reference com-
    mon with the direct input option. It is nominally +5 V and is pro-
    portional to the +15 Vdc supply.
    VELOCITY (VEL, PIN 23)
    The velocity output (VEL, pin 23) is a dc voltage proportional to
    angular velocity d
    θ/dt. The velocity is the input to the voltage con-
    trolled oscillator (VCO), as shown in FIGURE 1. Its linearity and
    accuracy are dependent solely on the linearity and accuracy of
    the VCO.
    The VEL output can swing ±10 V with respect to ground when
    the voltage level of the ±15 V power supplies are 15 V. The out-
    put level range changes proportionally with the power supply
    level. The analog output VEL characteristics are listed in TABLES
    5 and 6.
    The VEL output has dc tachometer quality specifications such
    that it can be used as the velocity feedback in servo applications.
