What are the key features of MCP604-I/ST?
- Quad op-amp configuration in 14-pin TSSOP-14 providing 4 independent voltage-feedback amplifiers in a compact SMD footprint
- 90 dB typical CMRR with 60 nA maximum input bias current for high-accuracy single-supply sensor signal conditioning
- Operates from 2.7 V single supply, enabling battery-powered and low-voltage analog front-end designs with internal frequency compensation
What is MCP604-I/ST used for?
The MCP604-I/ST is a strong fit for single-supply sensor amplification in portable instruments, medical monitoring devices, and battery-powered data loggers where four independent op-amp channels must be packed into a 14-pin TSSOP footprint. Its 90 dB CMRR and 60 nA bias current suit precision bridge amplifier and instrumentation front-end designs that require minimal offset error. Active filter banks and audio preamplifier stages in consumer electronics also benefit from its low-voltage 2.7 V operation and internal compensation.

Frequently Asked Questions
What is the minimum supply voltage for the MCP604-I/ST, and does it support single-supply operation?
The MCP604-I/ST operates from a minimum 2.7 V single supply, making it directly compatible with 3 V and 3.3 V systems without a negative rail. This is particularly valuable in battery-powered portable instruments where keeping supply complexity low and extending 2-cell alkaline battery runtime are design priorities alongside the 90 dB CMRR performance.
How does the MCP604-I/ST input bias current affect precision resistive bridge measurements?
With a maximum input bias current of 60 nA (0.00006 µA), the MCP604-I/ST introduces very low offset voltage across source resistances compared to bipolar input op-amps. In a 10 kΩ Wheatstone bridge, the 60 nA bias creates only 0.6 mV of worst-case offset, which is acceptable for 12-bit or 13-bit resolution signal chains in pressure and temperature sensing applications.
When should a designer choose MCP604-I/ST over a dual op-amp like the MCP602 for a 4-channel active filter design?
For a 4-channel active filter requiring matched CMRR of 75 dB minimum across all stages, the MCP604-I/ST provides all 4 voltage-feedback amplifiers in a single 14-pin TSSOP-14 package, reducing board area and inter-device matching variance compared to using two dual-amplifier packages. The single-package solution also cuts placement time and simplifies a 7-week lead-time procurement cycle to one line item.
