Zotino 32 channel DAC extension

Zotino is a 32 channel 16-bit DAC EEM, with an update rate of 1MSPS divided between the channels. It is based on an

bare PCB screened PCB

To do: make these images a sensible size (put them next to each other, rather than one on top of the other). Add a caption. Make a bit smaller?

Key info

  • DAC: AD5372BCPZ
  • Channel count: 32
  • Resolution: 16-bit
  • Update rate: 1MSPS divided between all channels
  • Output voltage: ±10V
  • Analogue bandwidth: 3rd-order Butterworth response with 75kHz cut-off; ?V/s slew-rate
  • Output impedance: 470Ohm in parallel with 2.2nF
  • Noise: <10ppm RMS integrated noise between 0.1Hz and 1kHz; 1nV/rtHz at 1MHz with 20dB-decade roll-off
  • Long-term stability: on-board temperature regulator for low drift. Quantify this.
  • Power and digital: supplied by a single EEM connector.
