9.2.1.2 Detailed Design Procedure
The DRV5053-Q1 has internal filtering that limits the bandwidth to at least 20 kHz. For this application no
external components are required other than the C1 bypass capacitor, which is 0.01 µF minimum. If the analog
output OUT is tied to a microcontroller ADC input, the equivalent load must be R > 10 kΩ and C < 10 nF.
