Product details
Overview
LMC6462AIM/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 (RL = 25 kΩ), and operates from 3.0 V to 15.5 V supply. It serves as a precision signal conditioner in transducer interfaces and portable medical sensors.
For engineers reviewing the LMC6462AIM/NOPB datasheet, LMC6462AIM/NOPB pinout, LMC6462AIM/NOPB application, or LMC6462AIM/NOPB equivalent, key selection criteria include ultra-low input bias current (150 fA), guaranteed rail-to-rail operation at 3V/5V, input common-mode range extending 0.2 V beyond rails, and suitability for high-impedance sensor front-ends requiring minimal loading and long battery life.
Technical Context
The LMC6462AIM/NOPB employs a CMOS input stage enabling 150 fA typical input current and >10 TΩ input resistance, critical for photodiode and high-value resistor networks. Its rail-to-rail input common-mode range (−0.2 V to V+ + 0.3 V) and rail-to-rail output swing (e.g., 0.010 V to 4.990 V at 5V/25 kΩ) support full dynamic range utilization in single-supply configurations.
It features 50 kHz gain-bandwidth product, 15 V/ms slew rate (5V), and 85 dB CMRR over 0–5 V common-mode range-enabling accurate amplification of small differential signals amid noisy supply or ground references. The device is characterized across −40°C to +85°C and supports stable operation with capacitive loads up to 200 pF using resistive isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 40 μA per amplifier (typical at 5V); enables >1-year battery life in coin-cell-powered instrumentation. |
| Input Offset Voltage | 0.25 mV (max at 25°C, 5V); ensures ≤2.5 mV output error at unity gain, critical for DC-coupled sensor bridges. |
| Input Bias Current | 150 fA (typical); minimizes voltage drop across >100 MΩ source impedances, preserving signal integrity. |
| CMRR | 85 dB (min, 0–5 V VCM at 5V); rejects power supply ripple and EMI-induced common-mode noise in portable devices. |
| Rail-to-Rail Output | Swings to within 10 mV of V+ and V− (5V, RL = 25 kΩ); maximizes ADC input range without level-shifting circuitry. |

| 3 | Output (A1) | Drives loads ≥25 kΩ rail-to-rail; internal 110 Ω sourcing / 83 Ω sinking impedance at 5V. |
| 4 | V− (Ground) | Reference for single-supply operation; connects to system ground or negative rail in split-supply designs. |
| 5 | Non-Inverting Input (A2) | Independent second channel input; identical specs to A1-supports dual-channel signal conditioning. |
| 6 | Inverting Input (A2) | Second high-Z input; usable for instrumentation amp configurations or independent sensor channels. |
| 7 | Output (A2) | Second rail-to-rail output; enables dual-sensor readout or active filtering without external op-amps. |
| 8 | V+ | Positive supply pin; accepts 3.0–15.5 V; decoupling capacitor required near pin for stability. |

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 |
|---|---|---|---|
| TLV2462IDR | Higher supply current (550 μA/amplifier), 2.5 mV VOS, 3.6 MHz GBW | Better AC performance but 27× higher quiescent power; unsuitable for multi-year battery use | Select when bandwidth >100 kHz is required and power budget allows >500 μA |

FAQ
What is the maximum operating supply voltage for LMC6462AIM/NOPB?
The LMC6462AIM/NOPB supports a supply voltage range of 3.0 V to 15.5 V. Absolute maximum rating is 16 V across V+ and V− pins. Operation above 15.5 V risks parametric degradation or reliability impact, especially under temperature stress. For 12 V industrial rails, the LMC6462AIM/NOPB remains fully specified and stable.
Does LMC6462AIM/NOPB support true rail-to-rail input common-mode voltage?
Yes, the LMC6462AIM/NOPB guarantees rail-to-rail input common-mode voltage range: −0.2 V to V+ + 0.3 V at 5 V supply, and −0.15 V to V+ + 0.3 V at 15 V. This allows direct interfacing with sensors whose output exceeds the supply rails-critical for bridge transducers and overvoltage-tolerant front-ends.
Can LMC6462AIM/NOPB drive capacitive loads without oscillation?
The LMC6462AIM/NOPB can reliably drive up to 200 pF capacitive loads at unity gain with 5 V supply. For larger loads (e.g., 300 pF), TI recommends resistive isolation (e.g., 100 Ω in series with output) or feedback compensation (e.g., R1/C1 network per Figure 38 in SNOS725D) to maintain phase margin and pulse fidelity.
What is the input bias current specification for LMC6462AIM/NOPB?
The LMC6462AIM/NOPB has a typical input bias current of 150 fA at 25°C, with a maximum of 10 pA over temperature. This ultra-low value enables use with photodiodes, pH electrodes, and high-value feedback networks (>100 MΩ) without significant DC error or signal attenuation.
Is LMC6462AIM/NOPB suitable for single-supply battery applications?
Yes-LMC6462AIM/NOPB is explicitly designed for single-supply battery operation. With 20 μA/amplifier quiescent current at 3 V, it achieves ~60 μW per amplifier, extending CR2032 battery life to >2 years in sleep-dominated sensor nodes. Its rail-to-rail I/O and −40°C to +85°C rating ensure robustness across battery discharge profiles.
