The AD1861N is a monolithic PCM audio digital-to-analog converter from Analog Devices. It integrates a voltage output amplifier, DAC, serial-to-parallel register, and voltage reference, fabricated with CMOS logic and bipolar/MOS devices for high performance audio playback. The device operates from a single 5 V supply for both analog and digital sections.
Key electrical specifications include 18-bit resolution, a typical signal-to-noise ratio of 110 dB, and a voltage output swing of ±3 V. The settling time is sufficiently fast to support 16x oversampling, though no numeric value is provided in the datasheet. The serial data interface accepts 2's complement input. An optional linearity trim pin is provided to eliminate residual differential nonlinearity at midscale, enabling low distortion reproduction.
The AD1861N is offered in a 16-pin plastic DIP (0.300", 7.62mm) with through-hole mounting. It is pin-compatible with the AD1856 and AD1860 audio DACs. Typical applications include high-end compact disc players, digital audio amplifiers, DAT recorders and players, and synthesizers.
The AD1861N has 18-bit resolution.
The typical SNR is 110 dB.
Both analog and digital supplies are 5 V nominal.
The typical output voltage swing is ±3 V.
It uses a serial interface with 2's complement data format.
It is available in a 16-pin DIP (0.300", 7.62mm) through-hole package.
Typical applications include high-end CD players, digital audio amplifiers, DAT recorders, and synthesizers.
