Adc test board
About the Adc test board
Adc test board is an open source PCB design by auselia, published on GitHub. It is a 2-layer board measuring 50 × 32 mm, with 67 components from 29 distinct parts.
Other key parts include the OPA2365, THS4531, ADS7057, XC6206P332MR-G and LM393. By type, the board carries 29 capacitors, 25 resistors, 7 ICs, 4 connectors and 1 diode.
From the project
ADS7057 test board: perfboard SMA -> filters -> ADC + wake comparator -> ZedBoard PMOD (KiCad 10, JLCPCB-ready)
The middle step between the perfboard and the AFE PCB. It takes the perfboard charge-amplifier output on an SMA connector, filters it, digitizes it with the ADS7057, and gives the SPI bus and a wake-up line to a ZedBoard PMOD port.
The topology is the one in the AFE v0.1 design description, rebuilt around JLCPCB Basic parts. Only the ADS7057, the OPA2365 and the THS4531 pay the $3.07 extended-part fee.
