Variable-Gain Amplifier
Figure 3 shows single-ended input, variable-gain ampli-
fiers (VGA). This VGA features more than 200kHz band-
width and is useful in automatic gain-control circuits
commonly found in baseband processors. The gain is
controlled by applying 0 to 1V to IN (V
GC
) of the
MAX4210D/E/F; 0V corresponds to minimum gain and
1V corresponds to maximum gain.
Measure Load Power
The MAX4210A/B/C and MAX4211A/B/C have internal
voltage-divider resistors connected to RS+ and the
analog multiplier input. This configuration measures
source power accurately and provides protection to the
power source such as a battery. To measure the load
power accurately, choose the MAX4210D/E/F and
MAX4211D/E/F with an external resistor-divider con-
nected directly to the load as shown in Figure 4. This
configuration improves the load-power measurement
accuracy by excluding the additional power dissipated
by R
SENSE
.
Power-Supply Bypassing
Bypass V
CC
to GND with a 0.1μF ceramic capacitor to
isolate the IC from supply-voltage transients. To pre-
vent high-frequency coupling, bypass RS+ or RS- with
a 0.1μF capacitor. On the TDFN and thin QFN pack-
ages, there is an exposed paddle that does not carry
any current, but should also be connected to the
ground plane for rated power dissipation.
