Acromag IP220 12-bit Analog Output Module

The Acromag IP220 is a 12-bit D/A analog output module in the Industry Pack form factor. It outputs analog voltage signals across 8 or 16 independent channels and installs into any ANSI/VITA 4-1995 compliant IP carrier card. In a four-slot carrier, you can pull 64 analog voltage outputs from a single card cage slot using four IP220 modules, which is why it shows up in high-channel-count ATE, motion control, and process simulation racks. Key Specs Form Factor: Industry Pack (IP), ANSI/VITA 4-1995 Output Channels: 8 or 16 analog voltage outputs (model dependent) Resolution: 12-bit per channel Output Range: ±10V bipolar DAC Architecture: Independent D/A converter per channel Settling Time: 11µS per channel Output Mode: Transparent (per-write) or simultaneous update Data Latches: Double-buffered per channel Calibration: Internally stored offset and gain coefficients Access Time: 375nS cycle (DAC data write, 8MHz clock) ID PROM: 32 x 8 EEPROM (IDSel interface) Operating Temp: 0°C to 70°C (standard), -40°C to 85°C (E models) Storage Temp: -55°C to 100°C Humidity: 5 to 95% non-condensing MTBF: 4,094,686 hours Each channel has its own dedicated 12-bit DAC. That is the spec that separates the IP220 from multiplexed output boards that share a single DAC across channels with sample-and-hold circuits. Individual DACs settle faster, eliminate the glitches that multiplexed architectures produce during re-acquisition, and let you write to any channel independently without disturbing others. What carrier card does the IP220 require? Any ANSI/VITA 4-1995 compliant Industry Pack carrier. Acromag makes a range of IP carriers for VME, PCI, CompactPCI, and standalone configurations. The IP220 itself is bus-agnostic since the carrier handles the host bus interface. If you need help matching the IP220 to a specific carrier or host platform, send us your system details and we will confirm compatibility. What is the difference between the IP220-8 and IP220-16? Channel count only. The IP220-8 has 8 analog output channels, the IP220-16 has 16. Resolution, output range, DAC architecture, and settling time are identical across both variants. The -E suffix (IP220-8E, IP220-16E) denotes the extended temperature version rated to -40°C to 85°C.
