Key Features
- Quad op-amp with 1.6 V minimum supply and rail-to-rail input/output for single-cell and low-voltage battery designs
- Ultra-low 0.0001 µA maximum input bias current minimises errors in high-impedance sensor and charge-amplifier circuits
- 80 dB typical CMRR with internal frequency compensation simplifies PCB layout for noise-sensitive signal conditioning
Applications
The MCP6044-I/SL suits low-power signal conditioning in portable medical devices, wearable sensors, and battery-powered data acquisition systems where a 1.6 V supply rail is standard. Its four amplifier channels in a single SOIC-14 package reduce component count in multi-channel filter, buffer, and instrumentation front-ends. The ultra-low bias current makes it an ideal choice for pH electrode amplifiers, photodiode transimpedance stages, and capacitive sensor interfaces.

Frequently Asked Questions
How low a supply voltage can the MCP6044-I/SL operate from, and what bandwidth does it provide?
The MCP6044-I/SL operates from a minimum supply of 1.6 V and provides a 10 kHz gain-bandwidth product, making it suitable for audio-frequency and sensor signal conditioning tasks in single-cell lithium or alkaline battery-powered systems.
Why is the 0.0001 µA input bias current of the MCP6044-I/SL important for pH sensor or photodiode interfaces?
At just 0.0001 µA maximum bias current, leakage at the input node remains below 0.1 nA, which is critical when the source impedance is in the megaohm range, such as with pH glass electrodes or reverse-biased photodiodes, preventing significant DC offset errors.
How does packaging four amplifiers in the MCP6044-I/SL SOIC-14 affect PCB area compared to four single op-amps?
The SOIC-14 package consolidates all 4 amplifiers into approximately 8.65 mm x 3.9 mm, saving roughly 60% board area versus four individual SOT-23-5 single op-amps, while also sharing a single decoupling capacitor on the shared supply pins.
