The curryman DAC is a stereo digital to analog converter with I2S input featuring the ES9023 Sabre
Premier Stereo DAC and an analog LCR output filter plus JFET buffer (“JG Filter Buffer” developed by
Joachim Gerhard) for improved high frequency noise suppression and output drive capability.
Features:
 I2S Input
 Stereo 2Vrms output unbalanced
 Improved LCR output filter for reduced HF noise
 JFET buffer/line driver with low output impedance (< 70 Ohm)
 On board low jitter 50MHz crystal oscillator (XO)
 On board low noise LDO regulators for DAC (3.6V) and XO (3.3V)
 Supported I2S input sample rates (kHz): 32, 44.1, 48, 88.2, 96, 176.4, 196
 Asynchronous mode operation using local XO as MCLK
 Power Supply:
o +4.5V to +12V DC (regulated or unregulated) for DAC and XO
o +/- 10V to +/- 18V DC (regulated, low noise) for output buffer

• MCLK <-> Niet verbinden
• BCK <-> Pin 12 (GPIO 18)
• LRCK <-> Pin 35 (GPIO 19)
• SDI <-> Pin 40 (GPIO 21)
• Ground <-> Pin 6 (GND)
