Product details
Overview
MCP6401T-E/OTVAO from Microchip Technology is a single-channel, rail-to-rail input/output operational amplifier optimized for ultra-low-power, precision signal conditioning in battery-powered systems. It delivers 45 µA typical quiescent current, 1 MHz gain bandwidth product, and operates across 1.8V–6.0V supply with extended -40°C to +125°C temperature range (E-temp grade). It serves as the front-end amplifier in sensor interfaces and portable medical instrumentation.
For engineers reviewing the MCP6401T-E/OTVAO datasheet, MCP6401T-E/OTVAO pinout, MCP6401T-E/OTVAO application, or MCP6401T-E/OTVAO equivalent, key selection criteria include its guaranteed rail-to-rail operation at 1.8V, ±0.8 mV max input offset voltage at 25°C, no phase reversal behavior, and SOT-23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The MCP6401T-E/OTVAO employs a dual-input-stage CMOS architecture enabling true rail-to-rail common-mode input voltage range (VSS – 0.2 V to VDD + 0.2 V at 1.8 V), with seamless transition between low- and high-VCM stages near VDD – 1.1 V. Its unity-gain stable design supports direct use in buffer, active filter, and precision rectifier configurations without external compensation.
It features microamp-level input bias current (1 pA typ), 71 dB min CMRR, and 78 dB min PSRR - all specified over full E-temp range - making it suitable for high-impedance sensor nodes where DC accuracy and power efficiency are co-critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-E/OT | Same SOT-23-5 package, but lower GBWP (1 MHz vs. 1 MHz), higher IQ (1 µA vs. 45 µA), and narrower temp range (-40°C to +85°C) | Limited to consumer-grade portable electronics; unsuitable for automotive or industrial ambient extremes | Select MCP6001T-E/OT only if cost is primary constraint and temperature or power requirements are relaxed |
| TSV911ICT | Higher GBWP (8 MHz), higher IQ (850 µA), same rail-to-rail I/O, but different pinout (VDD on Pin 8, VSS on Pin 4) and SO-8 package | Requires PCB redesign; better for high-speed filtering but incompatible with space-constrained SOT-23 layouts | Choose TSV911ICT only when bandwidth >1 MHz is required and board real estate permits SO-8 placement |
Compared with MCP6001T-E/OT, the MCP6401T-E/OTVAO provides 45× lower quiescent current and full E-temp qualification, while versus TSV911ICT it offers 19× lower power at the cost of bandwidth - making it the optimal choice for long-life, thermally demanding, space-constrained analog front-ends.

FAQ
What is the maximum operating junction temperature for the MCP6401T-E/OTVAO?
The MCP6401T-E/OTVAO has an absolute maximum junction temperature of +155°C. Its rated operating ambient temperature range is -40°C to +125°C (E-temp grade), and thermal resistance θJA is 220.7°C/W in SOT-23-5 package - meaning at 45 µA IQ and 5 V supply, self-heating remains negligible (<0.05°C) under normal PCB conditions. Always verify actual board-level thermal performance using worst-case power dissipation models.
Does the MCP6401T-E/OTVAO support true rail-to-rail input at 1.8 V supply?
Yes, the MCP6401T-E/OTVAO supports rail-to-rail input down to 1.8 V supply, with common-mode input voltage range specified as VSS – 0.20 V to VDD + 0.20 V at 1.8 V. This is confirmed in DS22229D-page 4 Table 1-2, and validated across temperature - enabling direct interfacing with resistive sensors and bridge circuits without level-shifting circuitry.
Is the MCP6401T-E/OTVAO pin-compatible with other members of the MCP640x family?
Yes, the MCP6401T-E/OTVAO shares identical pinout (SOT-23-5) with MCP6401, MCP6401R, and MCP6401U variants. All use Pin 1 = VOUT, Pin 2 = VIN−, Pin 3 = VIN+, Pin 4 = VDD, Pin 5 = VSS. Differences lie in internal trimming (offset, drift) and temperature grade - not pin function or physical layout - allowing drop-in replacement within the same package variant.
Can the MCP6401T-E/OTVAO drive a 10 kΩ load while maintaining rail-to-rail output swing at 1.8 V?
Yes, the MCP6401T-E/OTVAO guarantees rail-to-rail output swing into 10 kΩ loads at 1.8 V: VOH ≥ 1.790 V and VOL ≤ 0.010 V (typical) per DS22229D-page 4. This meets the definition of rail-to-rail output (within 10 mV of rails) and is verified across -40°C to +125°C - critical for maximizing ADC utilization in low-voltage systems.
What is the input noise performance of the MCP6401T-E/OTVAO at 1 kHz?
The MCP6401T-E/OTVAO exhibits 28 nV/√Hz input voltage noise density at 1 kHz, and 3.6 µVP-P integrated noise (0.1 Hz to 10 Hz). These values are specified in DS22229D-page 5 AC Electrical Specifications table and remain stable across temperature and supply voltage - supporting high-resolution sensor signal chains where noise floor directly impacts effective resolution.
