Analog Devices Inc. AD1852JRSZRL

Description
The AD1852 is a high-performance stereo digital audio playback system that includes a multibit sigma-delta modulator, digital interpolation filters, and analog output drive circuitry. It features an on-chip stereo attenuator and mute, programmable through an SPI-compatible serial control port. The AD1852 is compatible with DVD formats, including 192 kHz and 96 kHz sample frequencies and 24 bits. It also supports digital de-emphasis for 32 kHz, 44.1 kHz, and 48 kHz sample rates.

Features
Accepts 16-bit, 18-bit, 20-bit, and 24-bit data
Supports 24-bit, 192 kHz sample rate
Accepts a wide range of sample rates, including 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, and 192 kHz
Multibit sigma-delta modulator with "Perfect Differential Linearity Restoration" for reduced idle tones and noise floor
Data-directed scrambling DAC - least sensitive to jitter
