Key Features

  • Auto-zero architecture eliminates offset drift, achieving near-zero VOS over the full -40°C to 125°C range
  • 125 dB minimum CMRR (142 dB typical) for superior rejection of common-mode noise in sensor interfaces
  • Rail-to-rail input and output enables signal swing within millivolts of both supply rails from 2.3 V to 5.5 V
  • Ultra-low 0.005 µA max input bias current for high-impedance sensor conditioning without loading errors
  • Dual amplifier in compact 8-pin SOIC reduces component count in bridge amplifier and instrumentation designs

Applications

MCP6V28-E/SN is designed for precision signal conditioning in temperature sensing, pressure transducer amplification, and weigh-scale applications where offset drift and noise rejection are critical. Its auto-zero architecture continuously corrects offset voltage, making it suitable for slow-changing sensor signals in industrial and medical equipment operating from a 2.3 V to 5.5 V supply. The dual amplifier configuration simplifies differential-to-single-ended conversion for Wheatstone bridge sensors that require matched channel characteristics and high CMRR.

Frequently Asked Questions

How does MCP6V28-E/SN achieve low offset voltage over temperature?

MCP6V28-E/SN uses an auto-zero (chopper-stabilized) architecture that periodically samples and cancels the input offset, maintaining offset voltage below 5 µV typical and virtually eliminating offset drift over the -40°C to 125°C operating range, which is essential for precision DC measurements in industrial and medical sensor conditioning applications.

What is the CMRR specification of MCP6V28-E/SN and why does it matter for bridge sensor designs?

MCP6V28-E/SN specifies a minimum CMRR of 125 dB and a typical CMRR of 142 dB. In a Wheatstone bridge sensor circuit powered by a 5 V supply, this level of common-mode rejection reduces common-mode interference on the order of millivolts or less at the output, enabling accurate mV-level differential signal extraction even in electrically noisy industrial environments.

Can MCP6V28-E/SN operate in single-supply 3.3 V systems commonly used in low-power IoT designs?

Yes, MCP6V28-E/SN operates from a single supply as low as 2.3 V, making it compatible with 3.3 V IoT and battery-powered systems. Its rail-to-rail output swings within about 25 mV of each supply rail at a 10 kΩ load, maximizing the usable dynamic range and allowing direct interfacing with 12-bit or 16-bit ADCs without additional level shifting.

When would MCP6V28-E/SN be preferred over a standard op-amp for a weigh-scale application?

A standard op-amp with 1 mV typical offset and 5 µV/°C drift would introduce a 600 µV error over a 120°C span, unacceptable for a 0.1 g resolution at full scale. MCP6V28-E/SN's auto-zero architecture keeps offset below 5 µV and drift near 0 µV/°C, meeting the accuracy requirements of precision weigh-scale designs without external trimming or temperature compensation circuits.
