The AD1854KRS is a 5V stereo audio DAC system from Analog Devices. It accepts 16-, 18-, 20-, and 24-bit data and supports sample rates up to 96 kHz. The device uses a multibit sigma-delta modulator with perfect differential linearity restoration for reduced idle tones and noise floor. A data directed scrambling DAC makes it least sensitive to jitter, and differential output provides optimal performance. The AD1854KRS variant achieves 113 dB dynamic range, 112 dB SNR, and -101 dB THD+N at 48 kHz sample rate. On-chip volume control with 1024 steps, hardware and software controllable clickless mute, and zero input flag outputs for left and right channels are included. Digital de-emphasis processing and a switchable clock doubler add flexibility. The serial data port supports right-justified, left-justified, and I²S formats, and the serial control port uses SPI. The device is supplied in a 28-lead SSOP plastic package for surface-mount assembly. Applications include DVD, CD, set-top boxes, and home theater systems.
The nominal supply voltage is 5 V.
It comes in a 28-SSOP package (0.209", 5.30mm Width) surface-mount.
The part is listed as RoHS3 Compliant, but this information is unverified.
It supports 16-, 18-, 20-, and 24-bit data with 24-bit resolution.
The maximum sampling rate is 96 kHz.
It supports I2S, Left-Justified, Right-Justified, and SPI interfaces.
The typical dynamic range is 113 dB at 48 kHz sample rate for the AD1854KRS variant.
