The DRV601EVM2 customer evaluation module (EVM) demonstrates the integrated circuits DRV601RTJ
from Texas Instruments (TI).
The DRV601 is a stereo line driver designed to allow the removal of the DC-blocking capacitors for
reduced component count and cost. The DRV601 is ideal for single-supply electronics where size and
cost are critical design parameters.
The DRV601 is capable of driving 2 V
rms
into a 600- Ω load at 3.3-V supply. The DRV601 has external
gain-setting resistors that support a gain range of -1 V/V to -10 V/V and line outputs that have ± 8 kV IEC
ESD protection. The DRV601 has independent shutdown control for the left and right audio channels.
This EVM is configured with one TOSLINK™digital audio S/PDIF connector, two RCA phono input
connectors, and two RCA phono output connectors. Power supply is connected via a two-pin 2,54-mm pin
header.
