Product details
Overview
LMC7101AIM5/NOPB from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier in a 5-pin SOT-23 package. It delivers 1 MHz gain bandwidth, 0.01% THD at 10 kHz (5V, 10 kΩ), and 0.5 mA quiescent current at 5 V - enabling precision signal conditioning in space-constrained, battery-powered sensor interfaces and portable electronics.
For engineers reviewing the LMC7101AIM5/NOPB datasheet, LMC7101AIM5/NOPB pinout, LMC7101AIM5/NOPB application, or LMC7101AIM5/NOPB equivalent, key selection criteria include rail-to-rail operation across 2.7–15 V supplies, ±1 pA input bias current, industrial temperature range (–40°C to +85°C), and verified performance in low-distortion, low-power analog front-ends.
Technical Context
The LMC7101AIM5/NOPB uses a high-input-impedance CMOS input stage (>1 TΩ) with rail-to-rail differential pair architecture, enabling full-swing operation from V− to V+ without phase inversion. Its open-loop gain exceeds 80 V/mV (typical) at 5 V, supporting stable closed-loop configurations down to unity gain.
It features internal compensation for unity-gain stability and tolerates ≥100 pF capacitive loads at 15 V supply without oscillation. Input common-mode voltage extends 300 mV beyond either rail, and output swing reaches within 180 mV of rails (RL = 2 kΩ, 5 V), making it suitable for single-supply systems interfacing with ADCs and transducers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V - supports direct integration into 3 V, 5 V, and 12 V systems without level-shifting. |
| Gain Bandwidth Product | 1 MHz (typ.) - enables stable amplification up to ~100 kHz at gain = 10, suitable for sensor signal conditioning. |
| Input Bias Current | ±1 pA (typ.) - minimizes voltage error in high-impedance source applications (e.g., photodiode, pH electrode). |
| THD + N | 0.01% (10 kHz, 5 V, RL = 10 kΩ) - meets audio-grade and precision measurement linearity requirements. |
| Quiescent Current | 0.5 mA (typ. at 5 V) - enables >100-hour battery life in coin-cell-powered IoT sensors. |
| Operating Temperature | –40°C to +85°C - qualified for automotive cabin, industrial control, and outdoor portable equipment. |
| Input Offset Voltage | ±0.11 mV (LMC7101A grade) - reduces DC error in precision instrumentation without trimming. |
Pinout & Package
LMC7101AIM5/NOPB is housed in a 5-pin SOT-23 (DBV) package measuring 2.9 mm × 2.8 mm × 1.43 mm - optimized for minimal PCB area and low profile in ultra-thin devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplified signal node; capable of sourcing/sinking ≥16 mA (short-circuit limited); rail-to-rail swing. |
| 2 - V+ | Power | Positive supply terminal; accepts 2.7–15 V; decoupling capacitor required near pin. |
| 3 - +IN | Input | Noninverting input; high-impedance CMOS node (RIN > 1 TΩ); rail-to-rail common-mode range. |
| 4 - –IN | Input | Inverting input; matched to +IN for precision differential operation; no phase inversion beyond rails. |
| 5 - V− | Power | Negative supply terminal; may be ground in single-supply configurations; must be referenced to system GND. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3 V and 5 V single-supply systems - critical for maximizing ADC resolution. |
| Ultra-low input bias current | ±1 pA typical ensures <1 µV error across 1 MΩ source impedance - essential for electrochemical and piezoelectric sensors. |
| Tiny SOT-23 footprint | 50% smaller board area vs. SOIC-8; allows placement directly at signal source to minimize noise pickup and trace parasitics. |
| Low THD at audio frequencies | 0.01% at 10 kHz permits use in microphone preamps and voice-band signal chains without external filtering. |
| Wide supply flexibility | Characterized from 2.7 V to 15 V - eliminates need for separate op-amps across product variants using different battery chemistries. |

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 (1.2 mA), lower GBW (1.5 MHz), same rail-to-rail I/O and CMOS input. | Requires PCB redesign for dual-channel use; not drop-in due to pin count and package size mismatch. | Select when dual amplifiers are needed and board space allows SOIC-8; avoid for single-channel miniaturized designs. |
| MCP6001T-E/OT | SOT-23-5, but CMOS input with 1 pA IB (similar), lower GBW (1 MHz), higher VOS (1.5 mV max), and narrower temp range (–40°C to +125°C). | Acceptable for cost-sensitive consumer applications where offset drift is less critical than power. | Prefer for high-volume, non-precision applications; avoid where <0.5 mV offset or 0.01% THD is mandatory. |
Compared with LMC7101AIM5/NOPB, LMC6482IMX/NOPB offers channel density at the expense of layout compatibility and power efficiency, while MCP6001T-E/OT trades precision and distortion performance for broader temperature tolerance and lower unit cost - making LMC7101AIM5/NOPB optimal for space-constrained, low-distortion, industrial-grade signal conditioning.

FAQ
What is the maximum supply voltage for LMC7101AIM5/NOPB?
The absolute maximum supply voltage (VS = V+ – V−) for LMC7101AIM5/NOPB is 16 V. The recommended operating range is 2.7 V to 15.5 V. Operation above 15.5 V risks permanent damage, and exceeding 16 V violates absolute maximum ratings per TI SBOSAL2 datasheet Section 5.1.
Does LMC7101AIM5/NOPB support true rail-to-rail input and output?
Yes, LMC7101AIM5/NOPB supports rail-to-rail input common-mode voltage (extending 300 mV beyond V− and V+) and rail-to-rail output swing (e.g., 0.1 V to 4.9 V at 5 V supply, RL = 2 kΩ). This is confirmed in Sections 4, 5.7, and 6.3.1 of the official datasheet.
What is the input offset voltage specification for LMC7101AIM5/NOPB?
LMC7101AIM5/NOPB is offered in two grades: LMC7101A (±0.11 mV max, ±3 mV typ. at 25°C, 5 V) and LMC7101B (±0.11 mV max, ±7 mV typ.). The "AIM5/NOPB" suffix denotes the LMC7101A grade, verified in Table 5-7 of the TI SBOSAL2 datasheet.
Can LMC7101AIM5/NOPB drive capacitive loads directly?
LMC7101AIM5/NOPB can directly drive ≥100 pF capacitive loads at unity gain with 15 V supply without oscillation (Section 7.1.2). For larger loads or higher gains, resistive isolation (e.g., 300 Ω series resistor) is recommended to maintain phase margin and pulse fidelity.
Is LMC7101AIM5/NOPB qualified for automotive applications?
The standard LMC7101AIM5/NOPB is rated for industrial temperature (–40°C to +85°C) and is widely used in automotive cabin modules. For AEC-Q100 qualified versions, TI offers the LMC7101Q-Q1 - a distinct automotive-grade variant with extended testing and traceability not present in LMC7101AIM5/NOPB.
