AD1955 DAC V3.0 New Audio Decoder Board Support 24Bit 192K DSD128 with JRC5534x4 + LM4562NAx1 Op Amps
Description:
- It adopts LM4562NAx1 + 2x5534 singe to double (4pcs 5534 op amps in total) operational amplifiers.
- V3.0 New Version AD1955 DAC Decoder supports I2S or DSD signal input.
- Supports 24bit 192K for PCM mode.
- Supports I2S format left alignment format and right alignment format.
- Supports DSD64 and DSD128 for DSD mode.
K1 K2 Setting Sampling Rate:
Note: If the sampling rate is not configured correctly, the sound cannot be played normally.
K3 K4 Setting Data Format:
K5 Setting Bit Number:
- Short circuit K5, set PCM to 16 bit; disconnect K5, set PCM to 24 bit.
K6 Setting MCLK Mode:
- Short circuit K6, MCLK is 256Fs; disconnect K6, MCLK is 512Fs (if the MCLK mode configuration is incorrect, the sound cannot be played normally)
K7 Setting DSD Sampling Rate:
- Short circuit K7, set the sampling rate to DSD64; disconnect K7, set the sampling rate to DSD128 (due to the AD1955 chip, DSD128 mode may be unstable in some cases)
K8 Setting PCM/DSD Mode:
- The DSDON signals of K8 and I2S interfaces jointly control the switching of PCM/DSD mode. Since K8 and DSDON signals are connected to the same pin of the microcontroller, please disconnect DSDON (DSDON pin suspended) when using K8 control mode, and disconnect K8 when using DSDON control mode. When using K8, short circuit K8 for PCM mode and disconnect K8 for DSD mode. When using DSDON, the low input level is PCM mode, and the high input level is DSD mode.
I2S Interface Definition:
- 1 DSDON; 2 GND; 3 DATA; 4 BCK; 5 MCLK; 6 LRCK
Electric Parameters:
- PCB size: 9.99 x 8.64cm
- Screw hole central length and width: 9.349 x 7.995cm
- Power supply voltage: DC±15V for analog circuit (Note that it is a DC dual 15V input. Incorrect connection of AC or wire sequence can cause permanent damage to the circuit.); AC/DC7.5-10V for DAC chip power supply
Note:
- Due to the fact that the analog power supply of this board has dual DC inputs, a rectified, filtered, and stabilized power supply (not included) is required.
Package Included:
- 1 x DAC Board
