The Texas Instruments PCM1798DBR is a monolithic CMOS integrated circuit featuring stereo digital-to-analog converters (DACs) and support circuitry in a 28-lead SSOP package. This advanced segment DAC architecture provides excellent dynamic performance and improved tolerance to clock jitter.
Key specifications include a 24-bit resolution and a sampling rate of up to 200kHz. It offers a typical Signal-to-Noise Ratio (SNR) of 123dB and a Total Harmonic Distortion plus Noise (THD+N) of -106dB. The device supports dual-supply operation with 5V analog and 3.3V digital supplies, and its digital inputs are 5V tolerant.
Designed for audio applications, the PCM1798DBR utilizes an 8x oversampling digital filter with selectable rolloff characteristics (sharp or slow). It accepts standard, I2S, and left-justified PCM data formats. The device operates within a temperature range of -25°C to 85°C and is available in a compact 28-lead SSOP surface-mount package.
This component is pin-assignment compatible with the PCM1794, offering a similar functionality with a different pin-out. It is suitable for various home audio and specialty audio IC applications requiring high-fidelity digital-to-analog conversion.
