znbg3110 Zetex Semiconductors plc., znbg3110 Datasheet - Page 4

• Manufacturer Part Number: znbg3110
• Description: Fet Bias Controller With Polarisation 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
47nF are required for this 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
gate outputs and ground, C
5 . These parameters are lneearly related to V
6. These parameters are measured using Test Circuit 1
7. These parameters are measured using Test Circuit 2
