DESCRIPTION
The PCM1730 is a CMOS, monolithic integrated circuit
that includes stereo digital-to-analog converters and
support circuitry in a small 28-lead SSOP package. The
data converters utilize Texas Instruments’ advanced
segment DAC architecture to achieve excellent
dynamic performance and improved tolerance to clock
jitter. The PCM1730 provides balanced current outputs,
allowing the user to optimize analog performance
externally. Sampling rates up to 200 kHz are supported.
