Key Features
- Dual op-amp with 0.0001 µA typical input bias current for virtually zero loading on high-impedance sensors
- 1.8 V minimum supply operation with 14 kHz gain-bandwidth product for low-frequency precision signal conditioning
- 72 dB minimum CMRR (93 dB typical) in an 8-pin SOIC-8 package enabling differential signal accuracy from low-voltage rails
Applications
The MCP6032-E/SN is designed for ultra-low power sensor front-ends in portable medical devices, environmental monitors, and IoT edge nodes where supply voltages as low as 1.8 V and sub-nanoamp input bias currents are essential. Its dual-channel configuration with high CMRR supports differential measurement of strain gauges, thermocouples, and electrochemical sensors without introducing significant input loading error. The SOIC-8 package enables cost-effective dual-channel amplifier designs with minimal PCB area in battery-operated instruments.

Frequently Asked Questions
What is the typical input bias current of the MCP6032-E/SN and why does it matter for electrochemical sensor interfaces?
The MCP6032-E/SN has a typical input bias current of only 0.0001 µA (0.1 nA) at 25°C, which is effectively zero loading for high-impedance electrochemical sensors such as glucose electrodes or ion-selective probes. This prevents the tiny sensor current signal from being masked by amplifier input leakage, ensuring accurate readings at the sub-nanoamp signal levels common in biosensor applications operating from 1.8 V.
How does the MCP6032-E/SN's 93 dB typical CMRR benefit a differential temperature sensor circuit?
With a typical CMRR of 93 dB, the MCP6032-E/SN rejects common-mode noise on both thermocouple or RTD sensor leads by more than 90 dB, preserving the small differential temperature signal. In a low-voltage 1.8 V to 3.3 V supply environment where the differential signal may be only a few millivolts per degree, this high CMRR is critical to achieving accurate temperature readings without extensive external filtering.
Which low-power applications benefit most from the MCP6032-E/SN's 14 kHz gain-bandwidth product?
The 14 kHz gain-bandwidth product of MCP6032-E/SN is ideal for applications where signal frequencies are below 1 kHz and ultra-low power consumption is the priority, such as soil moisture sensors, air quality monitors, wearable biosensors, and slow-scan data loggers. For a unity-gain buffer, the full 14 kHz bandwidth is available; at a gain of 10, the usable bandwidth is still 1.4 kHz, sufficient for most dc and low-frequency environmental sensing applications powered from 1.8 V coin cells.
How does the dual-channel MCP6032-E/SN reduce BOM cost compared to using two single-channel op-amps in a two-stage sensor amplifier?
The MCP6032-E/SN integrates 2 independent op-amp channels in a single SOIC-8 package, reducing both IC count and PCB footprint compared to two separate 5-pin SOT-23 single-channel devices. In a two-stage instrumentation amplifier front-end, this halves the number of package footprints and assembly picks, lowering PCB area by approximately 40% and reducing per-unit assembly cost in high-volume portable instrument production.
