Applications
The MCP602-I/ST is suited for battery-powered sensor nodes and portable data-acquisition systems where a 2.7 V or 3.3 V single-supply dual op-amp with very low bias current is needed to interface high-impedance transducers such as pH electrodes, photodiodes, or piezoelectric films. Its industrial temperature grade (-40°C to +85°C) makes it reliable in outdoor environmental monitors, automotive accessories, and factory floor instrumentation exposed to wide ambient temperature swings. The dual-channel configuration also fits active filter stages and ADC buffer pairs in embedded systems where minimizing IC count and PCB area is critical.

Frequently Asked Questions
What is the minimum supply voltage of the MCP602-I/ST, and how does it fit into a 3.3 V microcontroller system?
The MCP602-I/ST operates from a minimum single supply of 2.7 V, well within the 3.3 V rail used by most modern microcontrollers and FPGAs. This means the op-amp can share the same power domain as the MCU without a separate voltage regulator, reducing BOM cost and current draw. Its rail-to-rail output can swing close to both supply rails, maximizing signal range within the 3.3 V supply window for ADC-front-end or DAC-buffer applications.
How does the 0.06 nA bias current of the MCP602-I/ST affect measurements from high-impedance sensors?
With a maximum average bias current of 0.06 nA (60 pA), the MCP602-I/ST introduces negligible current-sourced error even with source impedances up to tens of megaohms. A 10 MΩ source impedance multiplied by 60 pA yields only 0.6 µV of additional offset — far below the noise floor in most sensor systems. This makes the MCP602-I/ST appropriate for pH glass electrodes, reverse-biased photodiodes, and membrane-type humidity sensors where leakage current from the amplifier input must stay below 1 nA.
What temperature range does the I-suffix MCP602-I/ST support, and which outdoor or industrial applications benefit from that rating?
The I suffix designates an industrial temperature grade covering -40°C to +85°C. This range accommodates outdoor weather stations, automotive OBD accessory modules, industrial motor drives, and agricultural sensor systems that experience cold winter starts and hot summer ambient conditions. Using the I-grade version avoids the risk of op-amp parameter drift or oscillation that can occur if a commercial-grade (0°C to +70°C) device operates outside its rated temperature band.
Why might a designer choose MCP602-I/ST over a single-channel op-amp in a differential sensor amplifier?
A differential sensor amplifier such as a 2-op-amp instrumentation topology requires 2 matched input stages. The MCP602-I/ST provides both channels in a single 8-pin TSSOP footprint measuring approximately 3 mm × 4.4 mm, saving PCB area and reducing the matched-device selection burden compared to sourcing 2 separate single-channel parts. On-chip matching ensures both amplifiers share similar offset, bias current, and CMRR characteristics, improving differential rejection without careful part-to-part selection.
What CMRR does the MCP602-I/ST guarantee, and how does that compare in a 3.3 V single-supply signal chain?
The MCP602-I/ST guarantees a minimum CMRR of 75 dB with a typical value of 90 dB. In a 3.3 V supply chain, a 90 dB CMRR means a 1 V common-mode input variation is attenuated to about 32 µV referred to input — well below the 1 mV full-scale resolution of a 10-bit ADC operating on a 3.3 V reference. This is adequate for most sensor bridge amplifiers, active filters, and ADC driver stages in portable instruments and industrial sensor transmitters.
