The Acromag AVME9210 is an 8-channel analog output board for VMEbus systems delivering 12-bit resolution with jumper-programmable output ranges and exceptional linearity. Each channel features an independent D/A converter with ±10V, ±5V, ±2.5V, 0–5V, or 0–10V output capability. Non-linearity reaches just 0.013% of span maximum, while settling time to 1/2 LSB on 20V steps is 6.0 µs. Gain and offset temperature coefficients hold to 30 ppm/°C and 10 ppm/°C respectively, ensuring stable operation across 0–70°C environments.
