What are the key features of MCP6044-E/ST?
- Quad rail-to-rail input and output amplifier enabling full supply-range signal swing in low-voltage designs
- Ultra-low bias current of 5 nA max supporting high-impedance sensor interfaces with minimal loading error
- Single supply range of 1.4 V to 6 V compatible with both 1.8 V IoT and 5 V industrial systems
- 14-pin TSSOP package integrating 4 op-amp channels in a compact SMD footprint
What is MCP6044-E/ST used for?
The MCP6044-E/ST is optimized for low-voltage, low-power signal conditioning in portable consumer electronics, IoT sensor nodes, and battery-powered instrumentation that require 4 independent amplifier channels in a single package. Its rail-to-rail I/O capability allows signal processing all the way to the supply rails, maximizing dynamic range in 3.3 V and 5 V single-supply systems. Active filter stages, pH sensor interfaces, and photodiode transimpedance amplifiers benefit from the device's low bias current of 5 nA max and 62 dB CMRR.

Frequently Asked Questions
What supply voltage range does the MCP6044-E/ST support, and can it run from a single 3.3 V rail?
The MCP6044-E/ST operates from a single supply of 1.4 V to 6 V or a dual supply of ±0.7 V to ±3 V. A single 3.3 V supply is fully within this range, making the device directly compatible with modern microcontroller systems, ARM Cortex MCUs, and 3.3 V logic-level sensor interfaces without level-shift circuitry.
How does the rail-to-rail I/O specification of the MCP6044-E/ST benefit low-voltage signal chain designs?
Rail-to-rail input and output allows the MCP6044-E/ST's input common-mode range and output swing to extend within millivolts of both the positive and negative supply rails. On a 3.3 V supply this yields an effective signal dynamic range of approximately 3.28 V, compared to roughly 2 V for non-rail-to-rail designs, improving ADC utilization and SNR in data acquisition systems.
With a bias current of only 5 nA max, which sensor types pair well with the MCP6044-E/ST?
A 5 nA maximum bias current means the device introduces less than 5 µV of error across a 1 MΩ source impedance. This makes it ideal for electrochemical sensors, pH electrodes, photodiodes, and capacitive humidity sensors that present source resistances from 100 kΩ to several megaohms, where higher bias current amplifiers would introduce unacceptable DC offset errors.
How many amplifier channels does the MCP6044-E/ST integrate, and how does this affect PCB design compared to using single or dual op-amps?
The MCP6044-E/ST integrates 4 independent op-amp channels in a 14-pin TSSOP package measuring approximately 5 mm × 4.4 mm. Using a single quad device versus 4 single-channel op-amps reduces component count by 3 ICs, cuts PCB area by roughly 60%, and simplifies power decoupling to a single bypass capacitor pair.
