TDA8709A
Notes to the “Characteristics”
1.
0 dB is obtained at the AGC amplifier when applying V
i(p-p)
= 1.33 V.
2.
The output current at pin 19 should not exceed 1 mA. The load impedance R
L
should be referenced to V
CCA
and
defined as:
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
the clamp is not disturbed.
3.
Input signals with the same amplitude. Gain is adjusted to obtain ANOUT = 1.33 V (p-p).
4.
Signal-to-noise ratio measured with 5 MHz bandwidth:
V
V
ANOUT (RMS noise)
5.
The voltage ratio is expressed as:
20 log
V
=
for V
I
= 1 V (p-p), gain at 100 kHz = 1 and 1 V supply variation.
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
analog grounds is recommended.
These measurements are realized on analog signals after a digital-to-analog conversion (TDA8702 is used).
7.
8.
The supply voltage rejection is the relative variation of the analog signal (full-scale signal at input) for 1 V of supply
variation:
