NOTES:
1.All propagation delay times measured 50% to 50% from the negative going (from VCC to +0.4 V) edge of the clock.
2.Devices should not be operated at these values. The “Electrical Characteristics” provide conditions for actual device operation.
3.Dynamic total loop offset (
Σ
Voffset) equals VIO (comparator) (Figure 3) minus VIOX (Figure 5). The input offset voltages of the analog
comparator and of the integrator amplifier include the effects of input offset current through the input resistors. The slope polarity switch
current mismatch appears as an average voltage across the 10 k integrator resistor. The clock frequency is 16 kHz. Idle channel
performance is guaranteed if this dynamic total loop offset is less than one–half of the change in integrator output voltage during one
clock cycle (ramp step size).
