A Single-Supply, Remote Strain Gage Signal Conditioner
The circuit in Figure 11 illustrates a way by which the OP179/
OP279 can be used in a 12 V single supply, 350
strain gage
signal conditioning circuit. In this circuit, the OP179/OP279
serves two functions: (1) By servoing the output of the REF43’s
2.5 V output across R1, it provides a 20 mA drive to the 350
strain gage. In this way, small changes in the strain gage pro-
duce large differential output voltages across the AMP04’s
inputs. (2) To maximize the circuit’s dynamic range, the other
half of the OP179/OP279 is configured as a supply-splitter
connected to the AMP04’s REF terminal. Thus, tension or
compression in the application can be measured by the circuit.

Figure 11. A Single-Supply, Remote Strain Gage Signal
Conditioner
The AMP04 is configured for a gain of 100, producing a circuit
sensitivity of 80 mV/
. Capacitor C2 is used across the AMP04’s
Pins 8 and 6 to provide a 16-Hz noise filter. If additional noise
filtering is required, an optional capacitor, CX, can be used across
the AMP04’s input to provide differential-mode noise rejection.
A Single-Supply, Balanced Line Driver
The circuit in Figure 12 is a unique line driver circuit topology
used in professional audio applications and has been modified
for automotive audio applications. On a single 12 V supply, the
line driver exhibits less than 0.02% distortion into a 600
load
across the entire audio band (not shown). For loads greater than
600
, distortion performance improves to where the circuit
exhibits less than 0.002%. The design is a transformerless, balanced
transmission system where output common-mode rejection of
noise is of paramount importance. Like the transformer-based
system, either output can be shorted to ground for unbalanced
line driver applications without changing the circuit gain of 1.
Other circuit gains can be set according to the equation in the
diagram. This allows the design to be easily configured for
noninverting, inverting, or differential operation.
