... 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 MSM7533 and MSM7534 are best suited for an analog interface to an echo canceller DSP used in digital telephone terminals, digital PABXs, and hands free terminals. FEATURES • ...
