3rd-order

Σ∆, 2-channel D/A converter

OVERVIEW

The SM5878AM/AV is a 3rd-order

Σ∆, 2-channel

D/A converter LSI for digital audio reproduction

equipment.

It

also

incorporates

an

8-times

oversampling digital ﬁlter and analog, post-converter

lowpass ﬁlters.

The SM5878AM/AV has digital deemphasis ﬁlter,

attenuator, and soft mute circuits built-in. Double-

speed operation and low-voltage operation are also

supported.

SM5878AM/AV D/A converter incorporates 3rd-

order

∑∆ modulator and DEM (Dynamic Element

Mating) circuits for high performance, even in the

presence of clock jitter.

The SM5878AM/AV operates from a 4.5 to 5.5 V

supply, and is available in 24-pin SSOP or VSOPs.
