9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.

9.1 System Examples

Figure 21 shows the basic configuration for a bridge amplifier.

A low-side current shunt monitor is shown in Figure 22.

NOTE:

1% resistors provide adequate common-mode rejection at small ground-loop errors.
Figure 22. Low-Side Current Monitor

RN are operational resistors used to isolate the ADS1100 from the noise of the digital I2C bus. Because the ADS1100 is a 16-bit converter, a precise reference is essential for maximum accuracy. If absolute accuracy is not required, and the 5-V power supply is sufficiently stable, the REF3130 can be omitted.

Figure 23 shows the TLV333 in a typical thermistor circuit.
