Product details
Overview
LMC7101QM5X/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 typical quiescent current at 5V, and 0.01% THD at 10kHz - ideal for space-constrained, battery-powered sensor interface and portable audio signal conditioning.
For engineers reviewing the LMC7101QM5X/NOPB datasheet, LMC7101QM5X/NOPB pinout, LMC7101QM5X/NOPB application, or LMC7101QM5X/NOPB equivalent, key selection considerations include its rail-to-rail operation across wide supply ranges, ultra-low input bias current (±1pA), industrial temperature rating (–40°C to +85°C), and compact SOT-23 footprint enabling high-density PCB layouts in mobile and automotive electronics.
Technical Context
The LMC7101QM5X/NOPB employs a CMOS input stage with >1TΩ input resistance and 3pF input capacitance, enabling high-impedance sensor interfacing without significant loading. Its rail-to-rail output stage delivers full-swing capability down to 0.1V from rails under 2kΩ load at 5V supply.
It features stable unity-gain operation with ≥45° phase margin and supports direct drive of up to 100pF capacitive loads at 15V supply. Input common-mode range extends 300mV beyond both rails, eliminating phase inversion during overvoltage transients - critical for robust automotive and industrial signal acquisition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 15V - supports single-supply operation from low-voltage battery systems (2.7V) up to industrial 12V/15V rails without level-shifting. |
| Gain Bandwidth Product | 1MHz at 5V - enables stable closed-loop amplification up to ~10kHz with gain of 100, suitable for sensor signal conditioning and audio pre-amplification. |
| Input Bias Current | ±1pA typical - preserves accuracy in high-impedance source applications (e.g., photodiode, pH electrode, piezoelectric sensors) with minimal offset drift. |
| THD + N | 0.01% at 10kHz, 5V supply, 10kΩ load - ensures low-distortion analog signal integrity for portable audio and precision measurement front-ends. |
| Quiescent Current | 0.5mA typical at 5V - reduces power dissipation in thermally constrained designs and extends battery life in portable devices. |
| Operating Temperature | –40°C to +85°C - qualified for automotive cabin and industrial control environments without derating. |
| Input Offset Voltage | ±0.11mV (A-grade) - minimizes DC error in precision instrumentation and low-level signal amplification without external trimming. |
Pinout & Package

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, 1.5MHz GBW, 1.2mA IQ, SOIC-8 package - higher power, larger footprint. | Preferred where dual amplifiers are needed per board; not pin-compatible due to different channel count and package. | Select LMC6482IMX/NOPB only when dual-channel functionality and higher bandwidth justify increased size and current draw. |
| TLV2461IDBVR | Single-channel, 6.4MHz GBW, 0.65mA IQ, rail-to-rail I/O, SOT-23-5 - higher bandwidth but higher distortion (0.03% THD). | Better suited for higher-frequency active filters or fast-settling applications; less optimal for ultra-low-distortion audio. | Choose TLV2461IDBVR when bandwidth >1MHz is required and THD <0.02% is not critical. |
Compared with LMC7101QM5X/NOPB, LMC6482IMX/NOPB offers dual functionality at higher power and size cost, while TLV2461IDBVR trades lower distortion for higher bandwidth - making LMC7101QM5X/NOPB the optimal choice for space-constrained, low-THD, low-IQ sensor and audio applications.

FAQ
What is the maximum supply voltage for LMC7101QM5X/NOPB?
The absolute maximum supply voltage (VS = V+ − V−) for LMC7101QM5X/NOPB is 16V, with recommended operation up to 15.5V. Operation beyond 16V risks permanent damage. The device is fully characterized from 2.7V to 15V, supporting both low-voltage battery and standard industrial rail applications - all verified in the official SBOSAL2 datasheet revision January 2025.
Does LMC7101QM5X/NOPB support rail-to-rail input beyond the supply rails?
Yes, LMC7101QM5X/NOPB allows input voltages up to 300mV beyond either supply rail without phase inversion, a feature confirmed in Section 6.4.1.1 of the datasheet. This enables robust interfacing with overvoltage transients in automotive and industrial environments - though external current limiting (e.g., 10kΩ series resistor) is required if input current exceeds ±5mA.
What is the typical input offset voltage drift of LMC7101QM5X/NOPB?
The LMC7101QM5X/NOPB exhibits a typical input offset voltage drift of 1µV/°C over the full –40°C to +85°C industrial temperature range, as specified in Sections 5.5–5.8 of the SBOSAL2 datasheet. This low drift ensures stable DC performance in temperature-variable applications such as portable medical sensors and automotive cabin monitors.
Can LMC7101QM5X/NOPB drive capacitive loads directly?
LMC7101QM5X/NOPB can directly drive up to 100pF capacitive loads at unity gain with 15V supply while maintaining stability (≥45° phase margin), per Section 7.1.2. For larger loads (e.g., ADC inputs >100pF), resistive isolation (e.g., 300Ω series resistor) is recommended - a technique validated in Figure 7-1 of the datasheet.
Is LMC7101QM5X/NOPB pin-compatible with other SOT-23 op-amps?
LMC7101QM5X/NOPB uses the standard 5-pin SOT-23 (DBV) pinout: Pin 1 = OUT, Pin 2 = V+, Pin 3 = +IN, Pin 4 = –IN, Pin 5 = V−. It shares this layout with industry-standard single op-amps like TLV2461 and MCP6001, but functional compatibility (e.g., bandwidth, IQ, THD) must be verified per application - no generic pin-compatibility claim is made in TI documentation.
