10 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.

10.1 Application Information

This typical connection diagram highlights the required external components and system-level connections for

proper operation of the device. This configuration can be realized using the Evaluation Module (EVM) of the

device. This flexible module allows full evaluation of the device in all available modes of operation. Also see the

DRV632 product page for information on ordering the EVM.

10.2 Typical Application

R1 = 15 k

Ω, R2 = 30 kΩ, R3 = 43 kΩ, C1 = 47 pF, C2 = 180 pF

Differential-input, single-ended output, second-order filter
