The VMIVME-4132-010 is a 32-channel analog output board for VMEbus systems, delivering 12-bit DAC resolution with programmable voltage ranges from 0 to +10 V (unipolar) or ±10 V (bipolar). Each channel includes a dedicated sample-and-hold circuit and can source or sink ±10 mA across the full output range. The board features low output impedance (<0.1 Ω) and total error of ±0.05% of full-scale range, with maximum settling time to 1 LSB of 3.4 ms. Analog output codes support straight binary, offset binary, or two's complement formats.
