1 Export Control Notice
Recipient agrees to not knowingly export or re-export, directly or indirectly, any product or technical data
(as defined by the U.S., EU, and other Export Administration Regulations) including software, or any
controlled product restricted by other applicable national regulations, received from disclosing party under
nondisclosure obligations (if any), or any direct product of such technology, to any destination to which
such export or re-export is restricted or prohibited by U.S. or other applicable laws, without obtaining prior
authorization from U.S. Department of Commerce and other competent Government authorities to the
extent required by those laws.
2 Description
The DRV2634EVM-DC is designed to demonstrate the performance of DRV2634 and TAS2562 in a
stereo configuration. The design utilizes the PPC3-EVM-MB hardware to provide an interface and supply
voltages to the EVM. The TAS2562 is a mono, digital-input, Class-D audio amplifier optimized for
efficiently driving high peak power into small loudspeaker applications. The DRV2634 is a mono, digital-
input class-D amplifier optimized for haptic applications. The Class-D amplifier is capable of delivering 6 W
of peak power into a 4 Ωload at a battery voltage of 4.2 V. Up to four devices can share a common bus
via I2S/TDM + I2C interfaces.
DRV2634EVM-DC used in conjunction with PPC3-EVM-MB supports evaluation and development with the
DRV2634 device through the following interfaces:
• USB Interface
• Software control via PurePath™ Console 3 (PPC 3) GUI, USB-HID
• USB-class audio device, compatible with Microsoft™Windows™ 7+
• External 100 – mil headers
• PSIA - I2S/TDM interface
• I2C
• Hardware Shutdown Control
• Interrupt Output
NOTE: Please refer to PPC3-EVM-MB User’s Guide (SLEU120) for detailed configuration details.
3 Specifications
Table 1 lists the supply, input, and output requirements for DRV2634.
Table 1. Specifications
Supply Voltage - VBAT 2.7 to 5.5 V
Supply Voltage - VDD 1.65 to 1.95 V
Supply Voltage - PVDD (external mode olnly) VBAT to 16 V
Input Logic VDD
Output Power 6 W
USB, USB class-audio Micro-USB
NOTE: PPC3-EVM-MB supports a VBAT range from 4.5 to 26 V. To apply a VBAT supply in the
range of 2.7 to 4.5 V, it is highly recommended to remove Jumpers J3 and J6 and to apply
this voltage directly to pin 2 of the respective header while simultaneously powering PPC3-
EVM-MB with 5 V. Otherwise it is possible that on-board supplies may collapse.
