What are the key features of MCP609-I/ST?
- Quad op-amp with only 25 µA per channel supply current, enabling ultra-low-power analog signal conditioning on a single 2.5V supply
- 80 nA maximum input bias current and 75 dB minimum CMRR for accurate high-impedance sensor amplification
- 14-pin TSSOP package integrating 4 amplifiers in a compact footprint for space-sensitive portable designs
What is MCP609-I/ST used for?
The MCP609-I/ST is well-suited for battery-powered instruments, portable medical monitors, and IoT sensor nodes that need multiple analog amplification channels from a 2.5V to 5.5V single-supply rail. Its 25 µA per channel quiescent current makes it practical in always-on signal conditioning circuits where extending battery life to months or years is critical. The quad configuration allows four independent sensor channels to share a single 14-pin TSSOP footprint, minimizing BOM and PCB area.

Frequently Asked Questions
What supply current does each MCP609-I/ST amplifier channel draw and at what minimum supply voltage does it operate?
Each of the four MCP609-I/ST amplifier channels draws a maximum of 25 µA quiescent current from a supply as low as 2.5V, giving the quad package a total maximum supply current of 100 µA. This makes it practical for battery-operated designs where the op-amp must remain powered continuously without excessive drain on a 2-cell AA or single Li-ion source.
For a pH sensor front end, how does MCP609-I/ST handle high source impedance without loading the measurement?
The MCP609-I/ST specifies a maximum input bias current of 80 nA, which introduces only 80 µV of offset error across a 1 MΩ source impedance. Combined with 75 dB minimum CMRR, this makes it suitable for pH electrodes and other high-impedance electrochemical sensors where bias current and common-mode noise rejection are critical to measurement accuracy.
How does the 14-pin TSSOP package of MCP609-I/ST help reduce PCB area compared to using four single op-amps?
The MCP609-I/ST integrates 4 amplifiers in a 14-pin TSSOP package measuring approximately 5 mm x 4.4 mm, compared to four individual SOT-23 single op-amps that together would require roughly 4 times the placement area plus additional decoupling footprint. The quad integration also reduces the number of supply bypass capacitors from 4 to 1, further lowering bill-of-materials count.
