What are the key features of MCP6234-E/ST?
- Quad op-amp with 1.8 V minimum supply voltage enabling direct operation from single-cell Li-ion or coin-cell batteries
- Ultra-low 1.1 nA maximum input bias current with 75 dB typical CMRR for precision low-frequency sensor signal conditioning
- 300 kHz gain-bandwidth product in a TSSOP-14 package providing 4 channels in a compact 14-pin footprint
What is MCP6234-E/ST used for?
MCP6234-E/ST is used in battery-powered sensor modules, portable medical devices, and IoT edge nodes requiring four op-amp channels from a 1.8 V supply. Its 1.1 nA bias current and 75 dB CMRR make it well suited for high-impedance sensor interfaces, thermocouple amplifiers, and photodiode transimpedance stages. The TSSOP-14 package integrates all 4 channels in a small footprint for compact mixed-signal PCBs.

Frequently Asked Questions
What is the gain-bandwidth product and minimum supply voltage of MCP6234-E/ST?
MCP6234-E/ST has a 300 kHz gain-bandwidth product and operates from as low as 1.8 V single supply, making it ideal for low-frequency signal conditioning in battery-powered sensors and wearable devices running from small Li-ion cells.
How does the 1.1 nA bias current of MCP6234-E/ST benefit high-impedance sensor interfaces?
With a maximum input bias current of only 1.1 nA and 75 dB typical CMRR, MCP6234-E/ST introduces minimal loading error on high-impedance sources such as pH electrodes, photodiodes, and piezo sensors, preserving signal integrity in precision analog measurement circuits.
How many op-amp channels does MCP6234-E/ST integrate and what package does it use?
MCP6234-E/ST integrates 4 independent op-amp channels in a single TSSOP-14 package, reducing PCB area compared to using 4 single op-amps while maintaining 300 kHz bandwidth per channel for multi-channel sensor front-end designs.
