PCM1681TPWPRQ1

105dB SNR 8 通道音频 DAC（汽车类） 28-HTSSOP -40 to 105

The PCM1681 and PCM1681-Q1 are CMOS monolithic integrated circuits which feature an eight-channel 24-bit audio digital-to-analog converter DAC and support circuitry in small 28-lead TSSOP PowerPAD packages. The DACs utilize Burr-Brown"s enhanced multilevel delta-sigma ΔΣ architecture to achieve excellent signal-to-noise performance and a high tolerance to clock jitter.

The PCM1681 and PCM1681-Q1 accept TDM time-division multiplexed format in addition to industry-standard audio data formats with 16- to 24-bit audio data width. Sampling rates up to 200 kHz are supported. The PCM1681 and PCM1681-Q1 provide a sub-set of user-programmable functions through a parallel control port, in addition to a full set of user-programmable functions through a serial control port, SPI, or I2C. The PCM1681 supports –40°C to +85°C for consumer grade applications and the PCM1681-Q1 supports –40°C to +105°C for automotive audio grade systems.
