Abaco Systems / VMIC VMIVME-4116-070 8-Channel, 16-Bit Analog Output Board

The Abaco Systems / VMIC VMIVME-4116-070 is an 8-channel, 16-bit analog output board for VMEbus systems. It delivers independently configurable outputs across eight channels with ±10V range and 5 mA drive capability. Each channel integrates a dedicated 16-bit Digital-to-Analog Converter with 10 µs settling time (within 1/2 LSB), double-buffered data latches for simultaneous multi-channel updates, and software-controlled JFET output isolation switches. The board achieves ±1/2 LSB gain and offset error, differential linearity of ±0.003% of FSR, and linearity error of ±0.0015% of FSR at 25 °C, with typical gain and zero drift of ±10 PPM/°C and ±5 PPM of FSR/°C respectively.
