Acquisition Front-End Board parts and their functions
8 top-level parts · 246 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Bare PCB | 1× | Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it. |
| 2 | ECG Analog Front-End ASIC | 1× | ECG analog front-end ASIC |
| 3 | Instrumentation Amplifier | 8× | Per-lead instrumentation amps |
| 4 | 24-bit Sigma-Delta ADC | 1× | 24-bit sigma-delta ADC |
| 5 | Patient Isolation Barrier | 1× | Galvanic isolation per IEC 60601. |
| 6 | Defibrillator Protection Network | 10× | Per-electrode defib clamp |
| 7 | SMD Passive (R/C/L) | 220× | Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board. |
| 8 | Connector | 4× | Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering. |
