Application Circuit Examples

The minimum output analog load resistor is RL= 5kΩ. This optional load resistor can be configured as a pull-up or

pull-down. If it is configured as a pull-down, it cannot be part of the module to be calibrated because this would

prevent proper operation of the ZACwire™. If a pull-down load is desired, it must be added to system after

module calibration.

There is no output load capacitance needed.

Three-Wire Rail-to-Rail Ratiometric Output

This example shows an application circuit for rail-to-rail ratiometric voltage output configuration with temperature

compensation via an external diode.

Figure 4.1

Rail-to-Rail Ratiometric Voltage Output – Temperature Compensation via External Diode

The optional bridge sink allows a power savings of bridge current. The output voltage can be either

•

Rail-to-rail ratiometric analog output (ratiometric to VDD = Vsupply).

•

0 to 1V analog output. The absolute voltage output reference is trimmable 1V (+/-2mV) in the

1V Output Mode via a 4-bit EEPROM field. See section 2.4.3.
