• Manufacturer Part Number: 30016-RT
• Description: Audio IC Development Tools Emic 2 Text-2-Speech Module RETAIL PKG
• Manufacturer: Parallax

Connections
Emic 2 interfaces to a host microcontroller or computer system using only four connections (GND, 5V,
SOUT, SIN). Additional connections (SP+, SP-) are available for direct interfacing to an 8Ω speaker. A
1/8” (3.5mm) audio jack provides a single-ended, monaural output for easy connection to headphones,
amplified speakers, or other audio equipment.
Type: I = Input, O = Output, P = Power, G = Ground
Use the following example circuit for connecting the Emic 2 Text-to-Speech Module:
*Note: For audio output, a connection needs to be made to either SP+/SP- or the 1/8" audio jack. Audio
quality may be affected if both outputs are used at the same time.
