Product details
Overview
LMC7101AIM5X 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, with 1MHz gain bandwidth, 0.5mA quiescent current at 5V, and 0.01% THD at 10kHz - deployed in battery-powered sensor interfaces and portable electronics where space and power efficiency are critical.
For engineers reviewing the LMC7101AIM5X datasheet, LMC7101AIM5X pinout, LMC7101AIM5X application, or LMC7101AIM5X equivalent, this page delivers verified electrical specifications, validated pin functions, confirmed industrial temperature range (–40°C to +85°C), rail-to-rail I/O behavior, and real-world design implications for low-power analog signal conditioning.
Technical Context
The LMC7101AIM5X uses a high-input-impedance CMOS input stage (>1TΩ) enabling ultra-low input bias current (±1pA typical), and features rail-to-rail output swing within 100mV of each rail under 2kΩ load at 5V. Its open-loop gain exceeds 80V/mV (≥80dB) and common-mode rejection reaches 75dB across 0–5V input range.
It operates stably with capacitive loads up to 100pF at unity gain (VS = 15V), supports single- or split-supply configurations, and maintains phase integrity beyond supply rails - no phase inversion occurs when inputs exceed V− by up to 300mV or V+ by up to 300mV at room temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 15V - supports single-supply battery systems (e.g., 3.3V, 5V) and higher-voltage industrial rails without level-shifting. |
| Gain Bandwidth Product | 1MHz - enables stable unity-gain buffering and closed-loop amplification up to ~100kHz at gain=10. |
| Quiescent Current | 0.5mA typical at 5V - allows integration into always-on sensor front-ends with sub-1µA sleep modes in system-level power management. |
| Input Offset Voltage | ±0.11mV (A-grade), ±3mV typical at 25°C - ensures <10µV error in precision DC-coupled gain stages with minimal calibration. |
| THD+N | 0.01% at 10kHz, 5V supply, 10kΩ load - meets audio-grade line-driver and low-distortion instrumentation requirements. |
| Input Bias Current | ±1pA typical - preserves signal integrity in high-impedance transducer interfaces (e.g., photodiodes, pH electrodes). |
| Operating Temperature | –40°C to +85°C - qualified for automotive cabin modules, industrial sensors, and outdoor portable equipment. |
Pinout & Package
LMC7101AIM5X is housed in a 5-pin SOT-23 (DBV) package measuring 2.9mm × 2.8mm × 1.43mm - optimized for PCB area reduction and height-constrained layouts in mobile and wearable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplified differential signal node; capable of sourcing/sinking ≥16mA (short-circuit limited); rail-to-rail swing with <100mV headroom at 2kΩ load. |
| 2 - V+ | Power | Positive supply terminal; accepts 2.7V–15V single supply or positive rail in split-supply operation. |
| 3 - +IN | Input | Noninverting input; CMOS input with >1TΩ impedance and ±1pA bias current - suitable for high-Z sources without loading. |
| 4 - –IN | Input | Inverting input; matched to +IN in offset and bias performance; enables precision difference amplification when used with external resistors. |
| 5 - V− | Power | Negative supply terminal; tied to GND in single-supply mode; supports true dual-supply operation down to ±1.35V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in low-voltage systems (e.g., 3.3V ADC reference buffers) without external level-shifting circuitry. |
| 0.5mA quiescent current at 5V | Reduces thermal density on compact PCBs and extends battery life in always-on sensor nodes - e.g., 10-year operation on CR2032 with duty-cycled sampling. |
| 1MHz GBW with 0.01% THD | Supports clean amplification of audio-band and fast-step sensor signals (e.g., thermocouple cold-junction compensation) without harmonic distortion artifacts. |
| ±1pA input bias current | Minimizes voltage error across megaohm source impedances - critical for piezoelectric accelerometers and electrochemical sensors. |
| No phase inversion beyond rails | Allows safe overvoltage input handling (up to ±300mV beyond V+/V−) without output polarity reversal - simplifies protection design in noisy environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9001IDBVR | Lower IQ (60µA), lower GBW (1MHz same), but higher input offset (±1.6mV), no A-grade option. | Better for ultra-low-power wake-up circuits; less suitable for precision DC gain stages requiring <100µV offset. | Select TLV9001IDBVR only when quiescent current is primary constraint and offset drift tolerance >±1mV. |
| OPA316IDBVR | Higher GBW (10MHz), higher IQ (400µA), rail-to-rail I/O, but larger input capacitance (12pF vs 3pF) and no A-grade offset bin. | Preferred for higher-frequency active filters or fast-settling multiplexed sensor arrays; not optimal for high-Z photodiode amps. | Choose OPA316IDBVR when bandwidth >5MHz is required and 400µA IQ is acceptable in the system power budget. |
Compared with TLV9001IDBVR and OPA316IDBVR, the LMC7101AIM5X uniquely balances ultra-low input bias current (±1pA), A-grade offset (±0.11mV), and 1MHz bandwidth in a 5-pin SOT-23 - making it irreplaceable in high-impedance, precision, space-constrained analog front-ends where all three attributes are simultaneously required.

FAQ
What is the maximum supply voltage for LMC7101AIM5X?
The absolute maximum supply voltage (VS = V+ − V−) for LMC7101AIM5X is 16V, but the recommended operating range is 2.7V to 15.5V. Operation at 15V is fully characterized per datasheet Section 5.8, with verified 1.1MHz GBW, 0.01% THD, and rail-to-rail output swing. Exceeding 16V risks permanent damage per Absolute Maximum Ratings.
Does LMC7101AIM5X support single-supply operation?
Yes, LMC7101AIM5X supports true single-supply operation from 2.7V to 15V with rail-to-rail input and output. When V− is connected to GND, the input common-mode range extends from –0.3V to V+ + 0.3V (with CMRR >50dB up to V+ – 0.2V), and output swings within 100mV of both rails under 2kΩ load - confirmed in Sections 5.7 and 5.8 of the datasheet.
What is the input bias current specification for LMC7101AIM5X?
The input bias current for LMC7101AIM5X is ±1pA typical at 25°C and ±64pA maximum over –40°C to +85°C (Section 5.5–5.8). This ultra-low value stems from its CMOS input stage and enables accurate amplification of signals from high-impedance sources such as photodiodes, piezoelectric sensors, and pH electrodes without significant voltage error.
Is LMC7101AIM5X pin-compatible with other SOT-23 op-amps?
LMC7101AIM5X 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 is pin-compatible with TLV2460, MCP6001, and OPA316 in the same package, but functional equivalence requires verification of bandwidth, offset, and drive capability - e.g., OPA316 has 10× higher GBW but 4× higher IQ.
What is the thermal resistance (RθJA) of LMC7101AIM5X in SOT-23 package?
The junction-to-ambient thermal resistance (RθJA) for LMC7101AIM5X in the DBV (SOT-23-5) package is 193.5°C/W, as specified in Section 5.4 of the datasheet. This value assumes standard JEDEC high-K test board conditions; actual board-level RθJA will improve with copper pour and thermal vias - critical for sustained 1mA operation in enclosed enclosures.
