• Manufacturer Part Number: znbg3115
• Description: Znbg3115 - Fet Bias Controller With Polarization Switch And Tone Detection
• Manufacturer: Zetex Semiconductors plc.

TONE DETECTION CHARACTERISTICS
POLARITY SWITCH CHARACTERISTICS
NOTES:
1. The negative bias voltages specified are generated on-chip using an internal oscillator. Two external capacitors, C
purpose.
2. The characteristics are measured using an external reference resistor R
3. Noise voltage is not measured in production.
4. Noise voltage measurement is made with FETs and gate and drain capacitors in place on all outputs. C
ground, C
5 . These parameters are linearly related to V
6. These parameters are measured using Test Circuit 1
