The Curtiss-Wright/Systran ADC128F1-6A is a 12-bit simultaneous-sampling analog-to-digital converter delivering synchronized acquisition across eight independent channels. Each channel integrates a dedicated 12-bit switched-capacitor SAR ADC, enabling true parallel sampling of multiple analog signals with minimal cumulative error. The module updates its current value table every 8.625 µs and supports no-wait read-on-the-fly IP module accesses for deterministic system operation.
## Technical Specifications
• **Resolution:** 12-bit
• **Channels:** Eight independent simultaneous-sampling channels
• **ADC Architecture:** Switched-capacitor SAR-based
• **Input Voltage Range:** ±10 V single-ended
• **Input Resistance:** 16 kΩ
• **Relative Accuracy:** ±1 LSB (max.)
• **Differential Nonlinearity:** ±1 LSB (max.)
• **Update Rate:** 8.625 µs
• **Module Type:** Single-wide IndustryPack (IP) module
## Key Features
• Simultaneous sampling across all eight channels eliminates crosstalk and phase skew
• No-wait state access enables integration into systems without timing overhead
• Free-running operation with automatic power-up of all ADC channels
• Hardware and software handshake interfaces for cascading multiple ADC128F1 modules
• Modular IP architecture scales to 40 channels (VME via VMESC5 carrier) or 48 channels (PC via ISASC6 carrier) within a single slot
## Typical Applications
• Multi-channel data acquisition systems requiring phase-coherent sampling
• Defense and aerospace test instrumentation
• Real-time signal monitoring and analysis
• VME and PC-based instrumentation platforms
## Compatibility & Integration
The ADC128F1-6A operates as an IndustryPack module and integrates into carrier boards. VME systems employ the VMESC5 carrier for expansion; PC systems use the ISASC6 carrier. Software and hardware handshake protocols allow multiple modules to operate in synchronized configurations, simplifying architecture design for applications requiring channel counts beyond eight.
