Product details
Overview
LMC6462BIMX/NOPB from Texas Instruments is a dual micropower rail-to-rail input and output CMOS operational amplifier optimized for low-voltage, battery-powered systems. It delivers 20 μA/amplifier supply current, 0.25 mV input offset voltage, 85 dB CMRR at 5V, rail-to-rail output swing within 10 mV of rails (VS = 5V, RL = 25 kΩ), and operates from 3.0 V to 15.5 V supply. It is used in precision transducer interface circuits where ultra-low input current (150 fA) and wide common-mode range (−0.2 V to 5.3 V at VS = 5V) are critical.
For engineers reviewing the LMC6462BIMX/NOPB datasheet, LMC6462BIMX/NOPB pinout, LMC6462BIMX/NOPB application, or LMC6462BIMX/NOPB equivalent, key selection criteria include micropower operation under 3V/5V supplies, guaranteed rail-to-rail I/O performance across temperature, input bias current stability in high-impedance sensor nodes, and compatibility with single-supply instrumentation topologies such as two-op-amp in-amps and photodiode amplifiers.
Technical Context
The LMC6462BIMX/NOPB employs a CMOS input stage enabling rail-to-rail input common-mode voltage range extending 0.2 V beyond both supply rails and ultra-low input current (150 fA typical). Its output stage supports rail-to-rail swing into 25 kΩ loads, with sourcing/sinking capability up to ±27 mA at 5V and output resistance of 110 Ω (sourcing) / 83 Ω (sinking) at 5V.
It features 50 kHz gain-bandwidth product, 15 V/ms slew rate (5V), and maintains 85 dB CMRR over 0–5 V common-mode range. The device is characterized across −40°C to +85°C and specified for both 3V and 5V operation, with quiescent power of 60 μW per amplifier at 3V - making it suitable for always-on sensing nodes and portable medical devices requiring long battery life and DC precision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 15.5 V - supports single-supply operation in battery-powered and industrial systems without level-shifting. |
| Supply Current per Amplifier | 40 μA typical (5V), 55 μA max (5V) - enables multi-year operation on coin-cell batteries in low-duty-cycle sensor interfaces. |
| Input Offset Voltage | 0.25 mV typical (25°C, 5V) - ensures <100 μV output error at unity gain, critical for DC-coupled transducer signal chains. |
| Input Bias Current | 150 fA typical - preserves signal integrity in >1 GΩ source impedances (e.g., photodiodes, pH electrodes, piezoresistive sensors). |
| CMRR | 85 dB minimum (0–5 V VCM, 5V supply) - rejects power supply ripple and EMI in noisy environments like portable medical monitors. |
| Rail-to-Rail Output Swing | Within 10 mV of rails (VS = 5V, RL = 25 kΩ) - maximizes dynamic range in 8-bit–12-bit ADC front-ends without external level-shifting. |
| Gain-Bandwidth Product | 50 kHz - sufficient for DC–10 kHz sensor conditioning (e.g., thermocouple, strain gauge, gas sensor outputs). |
Pinout & Package
LMC6462BIMX/NOPB is housed in an 8-pin SOIC package (Package Drawing D), with thermal resistance θJA = 193°C/W. This surface-mount package supports automated assembly and provides adequate power dissipation for micropower operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (A1) | High-impedance node for feedback network connection; accepts signals down to −0.2 V below V−. |
| 2 | Non-Inverting Input (A1) | High-impedance node for reference or sensor input; supports rail-to-rail common-mode range. |
| 3 | Output (A1) | Capable of sourcing/sinking ≥27 mA; swing within 10 mV of V+ or V− into 25 kΩ load. |
| 4 | V− (Ground or Negative Supply) | Reference for dual-supply operation or ground return in single-supply configurations. |
| 5 | Non-Inverting Input (A2) | Independent second channel input; identical rail-to-rail common-mode specification as Pin 2. |
| 6 | Inverting Input (A2) | Second channel feedback node; matches Pin 1 electrical behavior and layout requirements. |
| 7 | Output (A2) | Second independent output; electrically isolated from Output A1; same drive strength and swing limits. |
| 8 | V+ (Positive Supply) | Accepts 3.0–15.5 V; internal regulation ensures stable biasing across full supply range. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 20 μA per amplifier typical - extends battery life in wearable health monitors and IoT endpoint sensors. |
| Rail-to-rail input common-mode range | Extends 0.2 V beyond both supply rails - eliminates need for input biasing resistors in single-supply transducer interfaces. |
| Rail-to-rail output swing | Within 10 mV of V+ or V− at 5V/25 kΩ - preserves full-scale resolution when driving SAR or delta-sigma ADCs directly. |
| Low input offset voltage drift | 1.5 μV/°C typical - maintains calibration stability over temperature in portable diagnostic equipment. |
| High input resistance | >10 TΩ - prevents loading errors in high-Z sources such as electrochemical sensors and capacitive touch elements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6482IMX/NOPB | Higher supply current (120 μA/amplifier), 1.5 mV VOS, wider GBW (1.5 MHz), same SOIC-8 package. | Better AC performance but 6× higher quiescent power - unsuitable for multi-year battery life targets. | Select when bandwidth >100 kHz or drive capability >50 mA is required; avoid when sub-50 μA per channel is mandatory. |
| TLV2462CDR | 65 μA/amplifier, 1.6 mV VOS, 6.4 MHz GBW, rail-to-rail I/O, SOIC-8. | Higher speed and drive, but 3× higher IB (1 pA) and reduced CMRR (75 dB) - less suited for high-Z DC sensors. | Prefer for mixed-signal systems needing fast settling into ADCs; not recommended for pH or photodiode front-ends demanding femtoampere IB. |
Compared with LMC6462BIMX/NOPB, LMC6482IMX/NOPB trades micropower efficiency for bandwidth and output drive, while TLV2462CDR offers higher speed at the cost of input current and CMRR - making LMC6462BIMX/NOPB the optimal choice for ultra-low-power, high-precision DC signal conditioning where battery longevity and sensor fidelity are primary constraints.

FAQ
What is the maximum operating supply voltage for LMC6462BIMX/NOPB?
The LMC6462BIMX/NOPB has an absolute maximum supply voltage (V+ − V−) of 16 V, with recommended operating range from 3.0 V to 15.5 V. At 15.5 V, output swing remains rail-to-rail into 100 kΩ loads, and supply current increases only marginally to 70 μA per amplifier - enabling flexible use in both 3.3 V and 12 V industrial sensor nodes. Exceeding 16 V risks permanent damage per Absolute Maximum Ratings.
Does LMC6462BIMX/NOPB support true rail-to-rail input at 3 V supply?
Yes, LMC6462BIMX/NOPB supports rail-to-rail input common-mode voltage at 3 V supply, with specified range from −0.10 V to 3.0 V (for CMRR ≥50 dB). This allows direct interfacing with sensors whose output spans near ground or near V+, eliminating external bias networks. The input stage uses CMOS transistors with threshold-tuned design to maintain functionality and linearity across the full range, verified in 3V DC Electrical Characteristics tables.
Can LMC6462BIMX/NOPB drive capacitive loads without oscillation?
LMC6462BIMX/NOPB can typically drive up to 200 pF capacitively at unity gain with 5 V supply without oscillation. For larger loads (e.g., 300 pF), TI recommends resistive isolation (e.g., 10–100 Ω series resistor at output) or compensation via feedback capacitor (Figure 36–38, SNOS725D). Uncompensated direct capacitive loading reduces phase margin and may cause ringing or instability - confirmed in Typical Performance Characteristics (Figure 37, Figure 39).
What is the guaranteed input offset voltage specification for LMC6462BIMX/NOPB over temperature?
LMC6462BIMX/NOPB is characterized as LMC6462BI grade, with guaranteed input offset voltage of 0.5 mV maximum at 25°C and 1.2 mV maximum over −40°C to +85°C (5 V supply). Its average drift is 1.5 μV/°C, meaning total VOS variation across full temperature range remains within 1.2 mV - critical for maintaining accuracy in uncalibrated portable instruments without trimming.
Is LMC6462BIMX/NOPB suitable for use as a comparator?
Yes, LMC6462BIMX/NOPB can be used as a micropower comparator, as documented in Figure 51 (SNOS725D). With 20 μA supply current and rail-to-rail output, it provides clean hysteresis-based decision thresholds in battery-powered systems. However, it lacks internal speed optimization - propagation delay is ~100 μs for 100 mV overdrive - so it is appropriate for low-frequency event detection (e.g., battery undervoltage alarm), not high-speed digital interfacing.
