Product details
Overview
LMC7101BIM5/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, 0.5 mA quiescent current at 5 V, 0.01% THD at 10 kHz, and operates across ±1.35 V to ±7.5 V (2.7 V to 15 V) supplies over –40°C to +85°C - ideal for space-constrained, battery-powered sensor interface circuits.
For engineers reviewing the LMC7101BIM5/NOPB datasheet, LMC7101BIM5/NOPB pinout, LMC7101BIM5/NOPB application, or LMC7101BIM5/NOPB equivalent, key selection criteria include rail-to-rail I/O swing under low supply current, input bias current below 64 pA, open-loop gain >80 V/mV, thermal resistance of 193.5°C/W, and compatibility with 100 pF capacitive loads without oscillation.
Technical Context
The LMC7101BIM5/NOPB uses a CMOS input stage enabling ultra-low input bias current (±1 pA typical) and high input resistance (>1 TΩ), supporting precision DC-coupled sensing. Its rail-to-rail output stage achieves 0.1 V to 4.9 V swing at 5 V supply into 2 kΩ, while maintaining phase margin ≥45° and gain margin ≥10 dB at unity gain.
It supports single-supply operation down to 2.7 V and dual-supply operation up to ±7.5 V, with PSRR ≥65 dB and CMRR ≥51 dB over full temperature range. Input common-mode voltage extends to both rails, with no phase inversion even when inputs exceed supply by ±0.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V single-supply or ±1.35 V to ±7.5 V dual-supply - enables direct use in 3 V, 5 V, and 12 V systems without level-shifting. |
| Gain Bandwidth Product | 1 MHz at 5 V - supports stable unity-gain buffer and closed-loop gains up to ~10 at 100 kHz. |
| Quiescent Current | 0.5 mA typical at 5 V - allows integration into always-on sensor nodes with multi-year battery life. |
| Input Offset Voltage | ±0.11 mV (min), ±9 mV (max) over temperature - ensures <10 µV drift in precision instrumentation front-ends. |
| Total Harmonic Distortion | 0.01% at 10 kHz, 5 V supply, 4 Vpp output - meets audio-grade signal fidelity requirements in portable DAC buffers. |
| Output Swing | Rail-to-rail: 0.1 V above V− and 0.1 V below V+ into 2 kΩ at 5 V - maximizes dynamic range in low-voltage ADC driver applications. |
| Input Bias Current | ±1 pA typical, ±64 pA max over –40°C to +85°C - minimizes voltage error across high-impedance sources like photodiodes or pH electrodes. |
Pinout & Package
LMC7101BIM5/NOPB is housed in a 5-pin SOT-23 (DBV) package measuring 2.9 mm × 2.8 mm × 1.43 mm - optimized for PCB area reduction and thin-profile portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking up to 24 mA short-circuit current at 5 V. |
| 2 - V+ | Positive power supply | Accepts 2.7–15 V single-supply or positive rail of dual-supply; decoupling capacitor required near pin. |
| 3 - +IN | Noninverting input | High-impedance CMOS node; common-mode range extends to both rails; input capacitance = 3 pF. |
| 4 - −IN | Inverting input | Matches +IN in impedance and voltage range; used for feedback configuration and differential sensing. |
| 5 - V− | Negative power supply / ground | Reference for single-supply operation (0 V) or negative rail in split-supply; must be low-impedance path. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal handling in low-voltage systems (e.g., 3.3 V ADC reference buffers) without clipping. |
| Ultra-low input bias current | ±1 pA typical preserves accuracy in high-Z sensor interfaces (e.g., piezoelectric transducers, ion-selective electrodes). |
| Low THD (0.01%) | Supports clean analog signal conditioning in audio paths and precision waveform generation stages. |
| 193.5°C/W junction-to-ambient thermal resistance | Allows operation at full rated load in compact enclosures without forced air cooling or heatsinks. |
| Capacitive load tolerance | Stable with up to 100 pF directly at output - simplifies driving multiplexers, ADC inputs, and long traces. |

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 (1.3 mA), lower GBW (1.5 MHz), same rail-to-rail I/O and CMOS input. | Requires PCB redesign for dual-channel needs; less suitable for ultra-low-power single-amplifier placements. | Select when dual amplifiers are needed and board area is not constrained. |
| TLV2461CDBVR | Single-channel, SOT-23-5; higher IQ (600 µA), higher GBW (6.4 MHz), rail-to-rail output only (not input). | Not suitable for true rail-to-rail input sensing (e.g., 0 V referenced sensors); better for higher-speed buffering. | Select when speed >1 MHz is required and input common-mode range to negative rail is not critical. |
Compared with LMC6482IMX/NOPB and TLV2461CDBVR, the LMC7101BIM5/NOPB uniquely combines single-channel SOT-23 packaging, rail-to-rail input/output, sub-1 mA quiescent current, and 1 MHz bandwidth - making it optimal for miniaturized, low-power, precision analog signal chains where input headroom to ground is essential.

FAQ
What is the maximum supply voltage for LMC7101BIM5/NOPB?
The LMC7101BIM5/NOPB has an absolute maximum supply voltage of 16 V (V+ to V−). It is characterized for operation from 2.7 V to 15 V single-supply or ±1.35 V to ±7.5 V dual-supply. Exceeding 16 V risks permanent damage per the Absolute Maximum Ratings table in the official datasheet. For reliable long-term operation, TI recommends staying within the Recommended Operating Conditions of 2.7 V to 15.5 V.
Does LMC7101BIM5/NOPB support true rail-to-rail input operation?
Yes, the LMC7101BIM5/NOPB supports true rail-to-rail input operation: its input common-mode voltage range extends to both supply rails (V− and V+), with no phase inversion observed even when inputs exceed either rail by up to 0.3 V. This is confirmed in Section 6.4.1.1 and Figure 6-1 of the datasheet, enabling accurate sensing of signals referenced to ground or supply in single-supply configurations.
What is the typical input bias current of LMC7101BIM5/NOPB at room temperature?
The typical input bias current of LMC7101BIM5/NOPB is ±1 pA at 25°C, with a maximum of ±64 pA over the full –40°C to +85°C industrial temperature range. This ultra-low value is enabled by its CMOS input stage and is critical for minimizing voltage error in high-impedance sensor interfaces such as photodiode amplifiers or pH electrode circuits.
Can LMC7101BIM5/NOPB drive a 100 pF capacitive load stably?
Yes, the LMC7101BIM5/NOPB is specified to drive up to 100 pF capacitive load stably at unity gain with VS = 15 V, as stated in Section 7.1.2. Its phase margin remains ≥45° under this condition. For larger loads or sensitive applications, TI recommends resistive isolation (e.g., 300 Ω series resistor) as shown in Figure 7-1 to ensure stability without compromising pulse response.
Is LMC7101BIM5/NOPB suitable for automotive applications?
The LMC7101BIM5/NOPB is rated for industrial temperature (–40°C to +85°C) and is used in automotive body electronics such as cabin temperature sensing and seat occupancy detection. However, for AEC-Q100 qualified automotive applications, TI offers the pin-compatible LMC7101Q-Q1 variant. Engineers should select LMC7101Q-Q1 for safety-critical or under-hood deployments requiring formal automotive qualification.
