Key Features
- 81 dB typical common-mode rejection ratio (CMRR) with 66 dB minimum for accurate differential signal amplification
- 5 nA maximum input bias current enabling accurate signal conditioning from moderate-impedance sensor sources
- Dual op-amp configuration in an 8-pin SOIC package reduces board space and component count for 2-channel designs
Applications
The MCP662-E/SN is suited for precision signal conditioning, sensor amplification, and active filter designs in portable instruments and industrial control systems. Its dual-channel architecture in a single SOIC-8 package is convenient for differential amplifier configurations and two-channel data acquisition front ends. The 5 nA input bias current and 81 dB CMRR make it a reliable choice for resistive bridge readout and thermocouple signal processing at audio and low-frequency bandwidths.

Frequently Asked Questions
What input bias current does the MCP662-E/SN specify, and how does this affect sensor signal conditioning circuit design?
The MCP662-E/SN specifies a maximum average input bias current of 5 nA (0.005 µA). In signal conditioning circuits with source impedances up to 100 kΩ, this bias current creates at most a 0.5 mV input error, which is acceptable for most precision measurement applications. For higher-impedance sources above 1 MΩ, the bias current contribution should be carefully evaluated and balanced using equal source impedances on both inputs.
How does the 81 dB typical CMRR of the MCP662-E/SN benefit differential measurement designs?
With 81 dB typical CMRR, the MCP662-E/SN rejects common-mode noise — such as 50/60 Hz power-line interference or ground-referenced offset voltages — by a factor of over 11,000:1. In practical terms, a 1 V common-mode signal at the inputs results in less than 0.1 mV of differential error, making the MCP662-E/SN suitable for bridge amplifiers, thermocouple interfaces, and other differential measurement circuits operating in electrically noisy environments.
For a 2-channel active filter design, what advantages does the dual MCP662-E/SN offer over two separate single op-amp packages?
Using the MCP662-E/SN dual op-amp saves PCB area compared to two individual 5-pin SOT-23 packages, as the 8-pin SOIC-8 footprint (3.9 mm body) integrates both amplifiers with shared power and ground pins. Both channels share the same silicon die, providing closely matched offset voltage, bias current, and CMRR — important for two-pole active filter designs where channel matching affects filter symmetry and cutoff frequency accuracy at the target bandwidth.
