Product details
Overview
LMC7101QM5/NOPB from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier in a 5-pin SOT-23 package, specified for supply voltages from 2.7V to 15V, delivering 1MHz gain bandwidth, 0.5mA quiescent current at 5V, and 0.01% THD at 10kHz - ideal for precision signal conditioning in space-constrained battery-powered systems.
For engineers reviewing the LMC7101QM5/NOPB datasheet, LMC7101QM5/NOPB pinout, LMC7101QM5/NOPB application, or LMC7101QM5/NOPB equivalent, key selection criteria include rail-to-rail I/O swing at low supply voltage, ultra-low input bias current (±1pA), industrial temperature range (–40°C to +85°C), and SOT-23 footprint compatibility with high-density portable layouts.
Technical Context
The LMC7101QM5/NOPB employs a CMOS input stage enabling femtoamp-level input bias current and >1TΩ input resistance, supporting high-impedance sensor interfaces without significant loading error. Its rail-to-rail output stage delivers full-swing capability down to 0.1V from each rail under 2kΩ load at 5V, while maintaining stable unity-gain operation with up to 100pF capacitive loads.
It features internally compensated frequency response with 1MHz GBW and 1V/µs slew rate at 5V, optimized for low-noise (37nV/√Hz) and low-distortion (0.01% THD) performance across 2.7V–15V supplies - enabling direct replacement of legacy amplifiers like LMC6482 in single-amplifier configurations without layout redesign.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 15V - supports single-supply operation from Li-ion (3.7V), USB (5V), and industrial rails (12–15V) without level-shifting. |
| Gain Bandwidth Product | 1MHz at 5V - enables stable closed-loop gain ≥10 at 100kHz for anti-aliasing and sensor signal amplification. |
| Input Bias Current | ±1pA typical - minimizes voltage drop across high-impedance sources (e.g., pH electrodes, photodiodes). |
| Quiescent Current | 0.5mA at 5V - allows integration into always-on sensor nodes with multi-year battery life at µA-level system budgets. |
| Input Offset Voltage | ±0.11mV (A-grade) - ensures ≤1.1mV total error in 10-bit ADC front-ends with 5V reference. |
| Output Swing | Rail-to-rail: 0.1V from V− and 0.1V from V+ at 2kΩ load - preserves dynamic range in low-voltage data acquisition. |
| THD+N | 0.01% at 10kHz, 5V supply - meets audio-grade line-driver and tone-generation requirements in portable devices. |
Pinout & Package
LMC7101QM5/NOPB uses the DBV (SOT-23-5) package: 2.9mm × 2.8mm footprint, 1.43mm height, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplified differential signal node; capable of sourcing/sinking ±24mA short-circuit current at 5V. |
| 2 - V+ | Power | Positive supply terminal; accepts 2.7V–15V; decoupling capacitor required within 1cm for stability. |
| 3 - +IN | Input | Noninverting input; high-impedance CMOS node (RIN > 1TΩ); tolerant of inputs up to 0.3V beyond rails. |
| 4 - −IN | Input | Inverting input; matched to +IN for common-mode rejection; requires symmetrical PCB trace routing for best CMRR. |
| 5 - V− | Power | Negative supply terminal; may be grounded in single-supply operation; must be connected even when V− = 0V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of supply voltage headroom in 3.3V and lower systems, preserving SNR in ADC drivers. |
| 0.5mA IQ at 5V | Reduces self-heating in dense layouts and extends runtime in coin-cell–powered IoT sensors. |
| 1TΩ input resistance | Eliminates loading error on high-Z transducers (e.g., piezoelectric accelerometers, electret mics). |
| 0.01% THD at 10kHz | Supports clean analog signal paths in voice recorders, medical pulse oximeters, and ultrasonic receivers. |
| Industrial temp range | Validated operation from –40°C to +85°C ensures reliability in automotive cabin modules and outdoor instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6482IMX/NOPB | Dual-channel SOIC-8; higher IQ (1.2mA), wider GBW (1.5MHz), but larger footprint and no A-grade option. | Suitable for dual-sensor systems where board area permits; not drop-in for LMC7101QM5/NOPB's SOT-23 layout. | Select when needing two matched amps in one package and thermal budget allows higher IQ. |
| MCP6001T-E/OT | Single SOT-23-5; lower GBW (1MHz same), higher IQ (100µA typ), but only rated to 7V max supply. | Limited to 3.3V/5V systems; lacks 15V capability and 0.01% THD spec - insufficient for high-fidelity audio or wide-supply industrial use. | Choose only for cost-sensitive, low-voltage (<7V), non-audio applications where ultra-low IQ is secondary. |
Compared with LMC6482IMX/NOPB and MCP6001T-E/OT, the LMC7101QM5/NOPB uniquely combines SOT-23-5 size, 15V operation, 0.01% THD, and ±1pA input bias - making it the sole option for space-constrained, wide-supply, low-distortion sensor interfaces requiring A-grade precision.

FAQ
What is the maximum supply voltage for LMC7101QM5/NOPB?
The absolute maximum supply voltage (VS = V+ – V−) for LMC7101QM5/NOPB is 16V, with recommended operation up to 15.5V. Electrical characteristics are fully specified at ±7.5V (15V total) and remain functional across 2.7V–15V - enabling use in both low-voltage battery systems and higher-voltage industrial rails. Exceeding 16V risks permanent damage per Absolute Maximum Ratings.
Does LMC7101QM5/NOPB support true rail-to-rail input at 2.7V supply?
Yes, LMC7101QM5/NOPB supports rail-to-rail input operation at 2.7V supply, with common-mode voltage range extending to within 0.3V of either rail (–0.3V to 3.0V). This is confirmed in Section 5.5 of the datasheet, where VCM min/max values are specified for 2.7V operation, and Figure 5-2 shows full input swing without phase inversion.
Can LMC7101QM5/NOPB drive a 10kΩ load with rail-to-rail output at 5V?
Yes - at 5V supply and 25°C, LMC7101QM5/NOPB delivers 4.7V to 4.9V positive swing and 0.1V to 0.18V negative swing into a 2kΩ load. Into 10kΩ, output swing improves further (data not tabulated but implied by reduced load current); typical rail-to-rail behavior holds across 600Ω–10kΩ, with worst-case swing still exceeding 4.6V/0.24V at full temperature range.
Is LMC7101QM5/NOPB qualified for automotive applications?
LMC7101QM5/NOPB is not the automotive-qualified variant; it is the commercial-grade part. The automotive version is LMC7101Q-Q1 (AEC-Q100 Grade 2, –40°C to +105°C). While LMC7101QM5/NOPB operates across –40°C to +85°C and shares identical electrical specs, it lacks AEC-Q100 certification, traceability, and enhanced reliability testing required for automotive safety-critical modules.
What is the input capacitance of LMC7101QM5/NOPB, and how does it affect high-frequency stability?
LMC7101QM5/NOPB has 3pF common-mode input capacitance (CIN) per input, as specified in Sections 5.5–5.8. When used with feedback resistors >500kΩ, this capacitance can interact with stray board capacitance to reduce phase margin. TI recommends adding a feedback capacitor (Cf) calculated via Equation 1/2 in Section 7.1.3 to maintain stability in high-gain, high-impedance configurations.
