Texas Instruments PCM510x Audio Stereo DACs
with 32-Bit PCM InterfaceTexas Instruments PCM5100 / PCM5101 / PCM5102 Audio Stereo Digital to Analog Converters (DACs) with 32-bit PCM Interface are part of a family of monolithic CMOS ICs that include a stereo DAC and additional support circuitry in a small TSSOP package. TI PCM5100 / PCM501 / PCM5102 DACs use the latest generation of TI's advanced segment DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. These TI DACs have an SNR (typical) of 100dB (PCM5100), 106dB (PCM5101), or 112dB (PCM5102). PCM510x devices are simpler hardware controlled 2VRMS DACs with filter select, PLL, and auto-mute functions. These TI audio stereo DACs are designed for use in A/V receivers, DVD / BD players, and HDTV receivers.
