1. 0 dB is obtained at the AGC amplifier when applying V
2. The output current at pin 19 should not exceed 1 mA. The load impedance R
3. Control mode 2 is selected.
4. Signal-to-noise ratio measured with 5 MHz bandwidth:
5. The voltage ratio is expressed as:
6. It is recommended that the rise and fall times of the clock are 2 ns. In addition, a ‘good layout’ for the digital and
7. These measurements are realized on analog signals after a digital-to-analog conversion (TDA8702 is used).
8. The supply voltage rejection is the relative variation of the analog signal (full-scale signal at input) for 1 V of supply

a) AC impedance 1 k and the DC impedance >2.7 k .
b) The load impedance should be coupled directly to the output of the amplifier so that the DC voltage supplied by
analog grounds is recommended.
