Fixed Differential Gain (AS1703, AS1704, and AS1705)
If the internal power dissipation exceeds the maximum allowed for a given package, power dissipation should be
reduced by increasing the ground plane heat-sinking capabilities and increasing the size of the device traces (see Sec-
tion 7.5 Layout and Grounding Considerations on page 9). Additionally, reducing V
CC
, increasing load impedance, and
decreasing ambient temperature can reduce device power dissipation.
The integrated thermal-overload protection circuitry limits the total device power dissipation. Note that if the junction
temperature is
≥
+145°C, the integrated thermal-overload protection circuitry will disable the amplifier output stage. If
the junction temperature is reduced by 9°, the amplifiers will be re-enabled.
Note:
A pulsing output under continuous thermal overload results as the device heats and cools.
7.3 Fixed Differential Gain (AS1703
,
AS1704, and AS1705)
The AS1703, AS1704, and AS1705 contain different internally-fixed gains (see Ordering Information on page 12). A
fixed gain facilitates simplified designs, decreased footprint size, and elimination of external gain-setting resistors.
The fixed gain values are achieved using resistors R
1
and R
2
(see Figure 3 on page 6).
7.4 Adjustable Differential Gain (AS1702)
7.4.1 Gain-Setting Resistors
The AS1702 uses external feedback resistors, R
F
and R
IN
(Figure 5), to set the gain of the device as:
where A
V
is the desired voltage gain. For example, R
IN
= 10k
, R
F
= 20k
yields a gain of 2V/V, or 6dB.
Note:
R
F
can be either fixed or variable, allowing the gain to be controlled by software (using a AS150x digital poten-
tiometer. For more information on the AS1500 family of digital potentiometers, refer to the latest version of the
AS150x data sheet
