ZSC31014EAG1 Integrated Circuit Chip Signal Conditioner with Digital Output for Resistive Sensors with High Accuracy and Wide Supply Voltage

ZSC31014 is a feature-rich RBiciLite™ CMOS integrated circuit that provides high-accuracy amplification and analog-to-digital conversion of differential input signals. Designed for cost-sensitive applications, it performs offset, span, and first- and second-order temperature compensation of the measured signal. Developed for resistive bridge sensor correction, the ZSC31014 can also provide a compensated temperature output using an internal or external temperature sensor.

• Wide supply voltage capability: 2.7V to 5.5V
• Current consumption as low as 70μA depending on programmed sample rate
• Low-power Sleep Mode (<2μA @ 25°C)
• Operation temperature: -40°C to +125°C

• High accuracy (±0.1% FSO @ -25 to +85°C; ±0.25% FSO @ -40 to +125°C)
• 2nd order charge-balancing analog-to-digital converter provides low noise, 14-bit data at sample rates exceeding 2kHz
• Fast power-up to data output response: 3ms at 4MHz
• Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity
• Eight programmable analog gain settings combine with a digital gain term; accommodates bridges with spans <1mV/V and high offset
• Internal temperature compensation for sensor correction and for corrected temperature output
• 48-bit customer ID field for module traceability
