Description
SigmaTel's STAC9750/51 are general purpose 18-bit ADC, 20-bit DAC, full duplex,
audio codecs conforming to the analog component specification of AC'97 (Audio
Codec 97 Component Specification Rev. 2.2). The STAC9750/51 incorporate Sig-
maTel's proprietary Σ∆ technology to achieve a DAC SNR in excess of 90 dB. The
DACs, ADCs, and mixer are integrated with analog I/Os, which include four analog
line-level stereo inputs, two analog line-level mono inputs, two stereo outputs, and
one mono output channel. The STAC9750/51 include digital input/output capability
for support of modern PC systems with an output that supports the SPDIF format.
The STAC9750/51 is a standard 2-channel stereo codec. With SigmaTel’s head-
phone drive capability, headphones can be driven with no external amplifier. The
STAC9750/51 may be used as a secondary codec, with the STAC9700/21/44/56/
08/84/66 as the primary, in a multiple codec configuration conforming to the AC'97
Rev. 2.2 specification. This configuration can provide true six-channel, AC-3 play-
