AD7190 Ultra Low Noise Pressure And Strain Gauge Data Acquisition Module With 24 Bit ADC For PLC DCS Analog Input High Precision Strain Bridge Sensor Interface
UPC:
✔️ 24-bit ADC, 8.5nV rms noise, 2 diff inputs, PG 1-128
High-precision data acquisition module built around the AD7190, designed for tight signal capture from pressure sensors, strain gauges, and electronic scales in PLC and DCS analog inputs. It combines a low-noise 24-bit ADC, on-chip PGA, buffering, and flexible input configurations for reliable industrial measurement.
✅ 24-bit Σ-Δ ADC with buffer, PGA, and digital filtering
✅ Two differential inputs or four pseudo-differential inputs
✅ Programmable gain 1-128 and automatic channel sequencing
✅ Noise performance: 8.5 nV rms (4.7 Hz, G=128) and up to 22.5-bit resolution (G=1)
✅ Output data rate selectable from 4.7 Hz to 4.8 kHz
✅ Chopper option reduces offset drift for stable long-term measurements
