Product Summary
The MSM7533HGS-KR1 is a two-channel CODEC CMOS ICs for voice signals ranging from 300 to 3400 Hz. The MSM7533HGS-KR1 contain filters for A/D and D/A conversion. Designed especially for a single-power supply and low-power applications, these devices contain two-channel AD/DA converters in a single chip and achieve a reduced footprint and a reduced number of external components. The MSM7533HGS-KR1 is best suited for an analog interface to an echo canceller DSP used in digital telephone terminal, digital PABX, and hands free terminal.
