Details

PRODUCT OVERVIEWThe AD1854 is a high performance, single-chip stereo, audio DAC delivering 113 dB Dynamic Range and 112 dB SNR (A-weighted—not muted) at 48 kHz sample rate. It is comprised of a multibit sigma-delta modulator with dither, continuous time analog filters and analog output drive circuitry. Other features include an on-chip stereo attenuator and mute, programmed through an SPI-compatible serial control port. The AD1854 is fully compatible with current DVD formats, including 96 kHz sample frequency and 24 bits. It is also backwards compatible by supporting 50 µs/15 µs digital de-emphasis intended for “redbook” 44.1 kHz sample frequency playback from compact discs.FEATURES 5 V Stereo Audio DAC System Accepts 16-/18-/20-/24-Bit Data Supports 24 Bits and 96 kHz Sample Rate Multibit Sigma-Delta Modulator with “Perfect Differential Linearity Restoration” for Reduced Idle Tones and Noise Floor Data Directed Scrambling DAC—Least Sensitive to Jitter Differential Output for Optimum Performance 113 dB Dynamic Range at 48 kHz Sample Rate (AD1854KRS) 112 dB Signal-to-Noise at 48 kHz Sample Rate (AD1854KRS) –101 THD+N (AD1854KRS) On-Chip Volume Control with 1024 Steps Hardware and Software Controllable Clickless Mute Zero Input Flag Outputs for Left and Right Channels Digital De-Emphasis Processing Supports 256 FS or 384 FS Master Mode Clock Switchable Clock Doubler Power-Down Mode Plus Soft Power-Down Mode Flexible Serial Data Port with Right-Justified, Left Justified, and I2S-Compatible 28-Lead SSOP Plastic PackageAPPLICATIONS DVD, CD, Set-Top Boxes, Home Theater Systems, Automotive Audio Systems, Sampling Musical Keyboards, Digital Mixing Consoles, Digital Audio Effects Processors
