UTC X3211 LINEAR INTEGRATED CIRCUIT
NOTES:
1. The negative bias voltages specified are generated on-chip using an internal oscillator. Two external capacitors,
CNB and CsuB of 47nFare required for this purpose.
2. The characteristics are measured using an external reference resistors RCAL of value 33kΩ wired from pins
RCAL to ground.
3. Noise voltage is not measured in production.
4. Noise voltage measurement is made with FETs and gate drain capacitors in place on all outputs. CG,4.7nF,are
connected between gate outputs and ground,CD,10nF,are connected between drain outputs and ground.
5. These parameters are linearly related to Vcc
6. These parameters are measured using Test Circuit 1
7. These parameters are measured using Test Circuit 2
