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.
