Key Features

  • Dual op-amp with rail-to-rail input and output for maximum signal swing on low-voltage rails
  • 200 kHz gain-bandwidth product suitable for audio and sensor signal processing
  • Ultra-low input bias current of 1.1 nA maximum for high-impedance sensor interfaces
  • Common-mode rejection ratio of 75 dB typical (61 dB minimum) for noise rejection
  • Operates from a single 1.8 V to 6 V supply, ideal for battery-powered designs
  • Internal frequency compensation for stable unity-gain operation
  • 8-pin SOIC package with standard 1.27 mm pitch for easy SMT assembly

Applications

MCP6232-E/SN is commonly deployed in portable medical devices, battery-powered sensor nodes, and precision data-acquisition front ends where rail-to-rail output swing and sub-microamp bias current are critical. Its low supply voltage compatibility also makes it a practical choice for IoT edge nodes and wearable electronics running from coin cells or single lithium cells.

Frequently Asked Questions

Can MCP6232-E/SN be used to amplify a bridge sensor signal from a 3.3 V microcontroller supply?

Yes. MCP6232-E/SN operates from 1.8 V to 6 V, covering a 3.3 V single-supply rail without issue. Its rail-to-rail output allows the amplified signal to swing within a few millivolts of both supply rails, maximizing dynamic range when feeding a 10-bit or 12-bit ADC input.

How does MCP6232-E/SN's 200 kHz gain-bandwidth product limit its closed-loop gain in audio-frequency designs?

At a gain of 10, the usable bandwidth is approximately 20 kHz, matching the upper limit of audio-frequency signals. For gains above 10, the bandwidth decreases proportionally—at a gain of 100, the -3 dB point drops to around 2 kHz—so MCP6232-E/SN is best suited for low-gain signal conditioning rather than wideband amplification.

What input bias current does MCP6232-E/SN draw, and what does that mean for high-impedance photodiode or pH-sensor interfaces?

MCP6232-E/SN has a maximum input bias current of 1.1 nA (1100 pA), which is low enough to work directly with high-impedance sensors such as photodiodes or pH electrodes whose source impedances can reach tens of megaohms. The resulting DC offset error at 10 MΩ source impedance stays below 11 mV, acceptable for many conditioning circuits.

What is the SOIC-8 package footprint of MCP6232-E/SN, and what are its soldering requirements?

MCP6232-E/SN comes in a standard 8-pin SOIC package with 1.27 mm pin pitch and a 3.9 mm body width. It is a Pb-free component compatible with standard lead-free solder reflow profiles peaking around 260°C, and its MSL rating allows exposure to typical manufacturing floor humidity without baking before assembly.

When would MCP6232-E/SN be chosen over MCP6242 or MCP6282 in a cost-sensitive dual op-amp slot?

MCP6232-E/SN targets designs requiring only 200 kHz bandwidth from a low-cost, low-supply-voltage amplifier. MCP6242 and MCP6282 offer wider bandwidths of 1 MHz and 2 MHz respectively, making MCP6232 the preferred choice when the signal bandwidth is below 20 kHz and minimizing supply current in battery-operated equipment is the primary design goal.
