High‑Precision Biosignal Acquisition Chip

Product Overview

The high‑precision biosignal acquisition chip acts as the core signal‑processing hardware for all‑kinds of electronic medical equipment. Designed with ultra‑low‑noise analog front‑end circuitry and medical‑grade reliability standards, the integrated chip picks up faint physiological signals including electrocardiogram, pulse wave, bio‑electric potential and body temperature. Built‑in signal filtering, gain adjustment and digital‑conversion units filter out environmental interference and convert weak analogue biological readings into standard digital data, supplying accurate raw‑signal sources for bedside monitors and portable diagnostic terminals.

Core Electrical & Performance Characteristics

• Ultra‑low input‑referred noise for capturing micro‑volt‑level weak biological signals

• Programmable multi‑stage gain adjustment adapting to different‑amplitude physiological signals

• Complete electromagnetic‑shielding property, complying with medical‑device EMC‑anti‑interference criteria

• Multiple‑channel synchronous sampling structure for multi‑parameter vital‑sign detection

• Low‑power consumption mode supporting long‑time operation of battery‑powered portable medical devices

Adaptable Working Conditions

The chip can steadily run inside high‑frequency‑interference hospital operating‑room surroundings, temperature‑variable ward equipment cabinets, frequently‑sterilized portable diagnostic hardware and long‑time‑working intensive‑care monitoring apparatus. It retains excellent sampling precision under frequent equipment startup‑and‑shutdown, humidity fluctuation and nearby high‑frequency medical‑device interference.

Product Advantages

The optimized low‑noise analogue front‑end effectively cuts signal distortion during biological‑signal collection. Multi‑channel synchronous sampling architecture reduces peripheral‑chip quantity and lowers the whole‑machine BOM expense. Custom‑built digital filter units get rid of power‑frequency interference without extra analogue circuits. Medical‑grade anti‑aging design satisfies long‑duration continuous‑operation requirements of hospital clinical instruments.

Application Scenarios

It is widely adopted within electrocardiograph machines, blood‑oxygen detectors, multi‑parameter bedside vital‑sign monitors, wearable physiological‑sensing gear and rehabilitation‑therapy signal‑detection equipment.

Selection & Usage Notes

Choose chips with matching sampling channels and noise indexes based on the medical instrument’s detection precision demands. Isolate analogue‑signal circuits from high‑speed digital traces on PCB layouts. Adopt isolated power‑supply design to prevent electric‑shock risks to patients. Avoid high‑temperature soldering procedures that could damage the sensitive analogue wafer inside the chip.
