MSM7543 Datasheet (OKI) - (MSM7544) Single Rail CODEC

MSM7543, (MSM7544) Single Rail CODEC

The MSM7543 and MSM7544 are single-channel CODEC CMOS ICs for voice signals ranging from 300 to 3400 Hz.

These devices contain filters for A/D and D/A conversion.

Designed especially for a single-power supply and low-power applications, these devices are optimized for telephone terminals in digital
