TS4990IQT based amplifier

STEVAL-CCA037V1

Overview

The STEVAL-CCA037V1 demonstration board is designed to evaluate the TS4990IQT low power audio amplifier. The micro package DFN8 (dual flat non-leaded 8 pins) allows space saving and good thermal dissipation.

The BTL gain is set at 2 V/V and can be adapted if necessary with a modification of two (R1 or R2) resistor values.
It is possible to modify the input configuration from single ended to differential of the STEVAL-CCA037V1 demonstration board.
More information regarding component calculations is available in the TS4990 datasheet.

How to make a self-propelled car
I want to make a self-propelled car by myself, including some functions such as obstacle avoidance and recognition, but I don't know what parts and materials I need. If anyone knows, can you share it
I want to buy a DSP development board for learning and developing video image processing. (Can anyone recommend one?)
Requirements: good performance, TI product, mainstream, preferably with rich video input and output interfaces, 6000 series, or DSP+ARM dual-core, or DSP+FPGA. Of course, it would be even better if it
