Page 2: Overview
Overview Overview The DRV600EVM evaluation module demonstrates the capabilities and performance of the DRV600RTJ from Texas Instruments. The DRV600 is a stereo line driver designed to allow the removal of the dc-blocking capacitors typically found in an audio application, reducing overall component count and cost. The DRV600 is ideal for single-supply electronics where size and cost are critical design parameters. -

It also provides information about handling and unpacking the module, absolute operating conditions, and a description of the factory default switch and jumper configuration. -
Page 5: Shutdown
For minimum click and pop interference during power-up and power-down, the shutdown pin should be kept low. The preferred power-up/-down sequence is shown in Figure DVDD SHUTDOWN > 50 s > 50 s Figure 4.

Page 8: Thd+N Vs Frequency (600Ω Load) Using X7R Input Caps
DRV600EVM Performance The DRV600EVM uses a 1μF film capacitor for ac-coupling of the input signal. If a lower cost ceramic capacitor such as an X7R is used, higher THD at low frequencies should be expected. Y5V capacitors will show even higher THD performance and should not be used. -

Page 10: Frequency Response
The low frequency cutoff of 10Hz (–3dB) is determined by the input ac-coupling capacitor together with the input impedance of the DRV600. A 1μF capacitor is used on the DRV600EVM. The input impedance of the DRV600 is 15kΩ. This impedance gives a –3dB cutoff of 10Hz. This result corresponds with the frequency response measurements above. -
