Product details
Overview
LMC6464BIM/NOPB from Texas Instruments is a quad 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 interface circuits requiring ultra-low input bias current (150 fA) and wide common-mode range.
For engineers reviewing the LMC6464BIM/NOPB datasheet, LMC6464BIM/NOPB pinout, LMC6464BIM/NOPB application, or LMC6464BIM/NOPB equivalent, key selection criteria include micropower operation under 3V, guaranteed rail-to-rail I/O performance across temperature, input offset drift of 1.5 μV/°C, and compatibility with high-impedance sensor nodes where leakage must be minimized.
Technical Context
The LMC6464BIM/NOPB employs a CMOS input stage enabling 150 fA typical input current and >10 TΩ input resistance, supporting high-precision DC-coupled measurement paths. Its rail-to-rail input common-mode range extends 0.2 V beyond both supply rails, and output swing is specified down to 25 kΩ loads - ensuring full dynamic range utilization in single-supply configurations.
It features 50 kHz gain-bandwidth product and 15 V/ms slew rate at 5V, with phase margin ≥50° and gain margin ≥15 dB. The device maintains 85 dB CMRR over 0–5 V common-mode range and exhibits 80 dB PSRR at 3V, making it suitable for noisy industrial or portable medical front-ends where supply rejection and common-mode immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 80 μA per amplifier max at 5V - enables >1-year battery life in 3V coin-cell systems with four active channels. |
| Input Offset Voltage | 0.25 mV typical at 25°C - contributes ≤2.5 mV error in unity-gain buffer at 10× gain, minimizing calibration burden. |
| Input Bias Current | 150 fA typical - allows use with >1 GΩ source impedances without significant voltage error or drift. |
| CMRR | 85 dB min at 0–5 V VCM (5V supply) - rejects >99.97% of common-mode interference in unshielded sensor traces. |
| Output Swing | Within 10 mV of rails at RL = 25 kΩ - preserves >99.6% of available signal headroom in 3.3V ADC interfaces. |
| Gain-Bandwidth | 50 kHz - supports stable DC-precision amplification up to ~5 kHz with ≥60° phase margin in unity-gain follower. |
| Operating Voltage | 3.0 V to 15.5 V - interoperable with Li-ion, alkaline, and industrial 12V supplies without level-shifting. |
Pinout & Package
LMC6464BIM/NOPB is housed in an 8-pin SOIC package (Package Drawing D), with thermal resistance θJA = 193°C/W. Pin assignments follow standard quad op-amp configuration: Pins 1/7/8/14 are outputs (OUT A/B/C/D); Pins 2/3/5/6 are inverting/non-inverting inputs (IN−A/IN+A/IN−B/IN+B); Pins 4 and 11 are V− and V+ power rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads ≥25 kΩ with rail-to-rail swing; requires no external pull-up/down in most sensor buffers. |
| 2 | IN− A | Inverting input A - accepts signals from −0.2 V to V+ + 0.2 V; guard ring layout mandatory for <1 pA leakage integrity. |
| 3 | IN+ A | Non-inverting input A - identical common-mode range as IN−; used for high-Z photodiode or thermocouple interfaces. |
| 4 | V− | Negative supply rail - connects to ground in single-supply systems; must be decoupled with 0.1 μF ceramic near pin. |
| 5 | IN− B | Inverting input B - electrically isolated from other sections; supports independent instrumentation channel routing. |
| 6 | IN+ B | Non-inverting input B - shares same ultra-low bias current spec; enables matched dual-channel differential sensing. |
| 7 | OUT B | Amplifier B output - identical AC/DC specs to OUT A; usable for dual-sensor conditioning or active filtering stages. |
| 8 | V+ | Positive supply rail - accepts 3.0–15.5 V; internal ESD protection rated to 2 kV HBM; avoid >13 V short-circuit to output. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends 0.2 V beyond both supply rails - enables direct interfacing to sensors operating outside supply domain (e.g., ±100 mV thermocouples on 3.3V rail). |
| Ultra-low input bias current | 150 fA typical - reduces voltage error to <150 μV across 1 GΩ source impedance, critical for pH electrodes and piezoresistive bridges. |
| Guaranteed 3V/5V operation | Full DC specs ensured at 3.0 V and 5.0 V - eliminates need for voltage translation in mixed-supply IoT nodes or portable diagnostics. |
| High CMRR at low voltage | 85 dB minimum at 3V supply - maintains rejection of 50/60 Hz pickup and switching noise in battery-powered ECG front-ends. |
| Low quiescent power | 60 μW per amplifier at 3V - allows integration of four precision channels in space-constrained wearables without thermal derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (550 μA/amplifier), lower CMRR (70 dB), no guaranteed 3V operation | Better AC performance (1.5 MHz GBW) but unsuitable for multi-year battery life or sub-3V systems | Select when bandwidth >100 kHz is required and power budget allows >6× higher quiescent draw |
| LPV821DR | Single-channel, 350 nA supply current, 10 μV offset, 10 kHz GBW | Lower power than LMC6464BIM/NOPB but lacks quad integration and rail-to-rail input | Choose for ultra-low-power single-ended sensor nodes where channel count and common-mode range are secondary |

FAQ
What is the maximum supply voltage for LMC6464BIM/NOPB?
The absolute maximum supply voltage (V+ − V−) for LMC6464BIM/NOPB is 16 V, with recommended operating range from 3.0 V to 15.5 V. Operation above 15.5 V risks permanent damage; sustained operation at 15.5 V requires thermal derating per θJA = 193°C/W and junction temperature limits of 125°C for the BI grade.
Does LMC6464BIM/NOPB support true rail-to-rail input beyond the supply rails?
Yes, LMC6464BIM/NOPB supports input common-mode voltage from −0.2 V to V+ + 0.2 V at 5V supply, verified across temperature. This allows direct connection of sensors whose output exceeds the supply (e.g., thermocouples), provided input current is limited to ±5 mA via external series resistors per TI application guidance.
What is the typical input bias current specification for LMC6464BIM/NOPB?
The typical input bias current for LMC6464BIM/NOPB is 150 fA at 25°C, with a maximum of 10 pA over temperature. This ultra-low value enables use with high-impedance sources such as pH electrodes, photodiodes, and piezoresistive sensors without measurable loading error or drift.
Can LMC6464BIM/NOPB drive 25 kΩ loads while maintaining rail-to-rail output swing?
Yes, LMC6464BIM/NOPB guarantees rail-to-rail output swing within 10 mV of each rail when driving ≥25 kΩ loads at 5V supply. At 3V supply, output swing is specified to within 50 mV of rails under the same load condition, preserving >95% of available dynamic range in low-voltage systems.
Is LMC6464BIM/NOPB RoHS compliant and lead-free?
Yes, LMC6464BIM/NOPB is RoHS compliant and lead-free, with "Green (RoHS & no Sb/Br)" eco plan designation and SN (matte tin) lead finish. It meets JEDEC J-STD-020 moisture sensitivity level 1 (260°C peak reflow), and is qualified for industrial temperature range (−40°C to +85°C).
