OneAudio·OSVA·AA2380V1.00_Final/AA2380V1.kicad_pcb

OSVA is an open source PCB design by OneAudio: a 125 × 150 mm board with 357 components (106 distinct parts). It is built around the LTC6655CHMS8-5, LT6202CS5, NL17SZ74, NC7SZ04M5X and more. Filed under audio.

Open source versatible analyzer (24bits 1.536MSPS 2 Channels)

The OSVA project is a 2 channels signal analyzer using high resolution SAR ADC (LTC2380-24). It has been designed to be used as system analyser but using standard digital audio interface.

The OSVA project include 4 sub-design (boards): ----------------------------------------------- 1. AA2380 - 2 channels ADC board : It is the main board. 2. AA10M08 - CPLD digital board : Optional board 3. AAPSU01 - Low noise SMSP board 4. AACMD01 - Command panel board
