Rochester Electronics Data Acquisition - Digital to Analog Converters (DAC) AD1868N-J

The AD1868N-J is a dual 18-bit digital-to-analog converter (DAC) designed for audio applications, operating on a single +5 V power supply. It features a total harmonic distortion plus noise (THD+N) of 0.004% and a signal-to-noise ratio (SNR) of 97.5 dB, ensuring high-quality audio output. The device supports a maximum clock input frequency of 13.5 MHz and is compatible with various digital filter chips, making it versatile for integration into multimedia workstations, portable CD players, and automotive audio systems. The AD1868N-J is packaged in a 16-pin plastic DIP or SOIC format and requires no external deglitcher or trimming circuitry, simplifying design and implementation. It operates effectively over a temperature range of -35¬8C to +85¬8C and typically dissipates 50 mW of power. The buffered output voltage range is between 1.5 V and 3.5 V, with a load current capability of up to 1 mA. This DAC is suitable for engineers seeking a reliable and efficient solution for high-fidelity audio applications.
