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 Application Information

The TLV905x family features 5-MHz bandwidth and very high slew rate of 15 V/µs with only 330 µA of supply

current per channel, providing excellent AC performance at very low-power consumption. DC applications are

well served with a very low input noise voltage of 15 nV/

√Hz at 10 kHz, low input bias current, and a typical input

offset voltage of 0.33 mV.

9.2 Typical Low-Side Current Sense Application

Figure 41 shows the TLV905x configured in a low-side current sensing application.

9.2.1 Design Requirements

The design requirements for this design are:

•

Load current: 0 A to 1 A

•

Output voltage: 4.95 V

•

Maximum shunt voltage: 100 mV
