AD28MSP02 General Description

The AD28msp02 Voiceband Signal Port is a complete analog front end for high performance voiceband DSP applications. Compared to traditional m-law and A-law codecs, the AD28msp02's linear-coded ADC and DAC maintain wide dynamic range while maintaining superior SNR and THD. A sampling rate of 8.0 kHz coupled with 65 dB SNR + THD performance make the AD28msp02 attractive in many telecom and speech processing applications, for example digital cellular radio and high quality telephones. The AD28msp02 simplifies overall system design by requiring only a single +5 V power supply.

The inclusion of on-chip anti-aliasing and anti-imaging filters, 16-bit sigma-delta ADC and DAC, and programmable gain
amplifiers ensures a highly integrated and compact solution to voiceband analog processing requirements. Sigma-delta conversion technology eliminates the need for complex off-chip antialiasing filters and sample-and-hold circuitry.

The AD28msp02's serial I/O port provides an easy interface to host DSP microprocessors such as the ADSP-2101, ADSP-2105 and ADSP-2111. The AD28msp02 is available in a 24-pin, 0.3" plastic DIP and a 28-lead SOIC package.
