The DRV612EVM customer evaluation module (EVM) demonstrates the capabilities and operation of the DRV612 integrated circuit from Texas Instruments. It is a single-ended, 2-Vrms stereo line driver designed to reduce component count, board space and cost. It is ideal for single-supply electronics where size and cost are critical design parameters.
The DRV612 does not require a power supply greater than 3.3V to generate its 5.6-Vpp output, nor does it require a split-rail power supply.
The DRV612 is designed using TI’s patented DirectPathTM technology, which integrates a charge pump to generate a negative supply rail that provides a clean, pop-free ground-biased output. The DRV612 is capable of driving 2Vrms into a 600-Ω load. DirectPathTMtechnology also allows the removal of the costly output dc-blocking capacitors.
It is available in a 14-pin TSSOP package. For a footprint-compatible stereo headphone driver, see TPA6139A2.
This EVM is configured with two RCA phono input connectors for analog input. The output signal is available on two RCA phono connectors. The power supply is connected via a two-pin, 2.54-mm header. This evaluation board is designed for testing applications such as set-top boxes, LCD/PDP TVs, Blu-ray Disc&trade DVD players, DVD mini-component systems, home theater-in-a-box (HTIB) systems, or soundcards.
