Product details
Overview
LMC6464BIMX 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 150 fA input bias current - enabling high-accuracy signal conditioning in portable medical sensors and transducer interfaces.
For engineers reviewing the LMC6464BIMX datasheet, LMC6464BIMX pinout, LMC6464BIMX application, or LMC6464BIMX equivalent, this page provides verified specifications, SOIC-14 package mapping, real-world instrumentation circuit use cases, and two validated alternative op-amps with documented parameter trade-offs.
Technical Context
The LMC6464BIMX employs a CMOS input stage with ultra-high input resistance (>10 TΩ) and rail-to-rail common-mode range extending 0.2 V beyond both supply rails. Its output stage supports true rail-to-rail swing under 25 kΩ loads while maintaining 3000 V/mV large-signal voltage gain and 50 kHz gain-bandwidth product at 15 V supply.
It operates across 3.0 V to 15.5 V single-supply or ±1.5 V to ±7.75 V dual-supply configurations, with guaranteed performance at both 3 V and 5 V. Input protection limits current to ±5 mA, and ESD tolerance is rated at 2.0 kV (HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 80 μA per amplifier max at 5 V - enables >1-year battery life in 3-V coin-cell–powered sensor nodes. |
| Input Offset Voltage | 0.25 mV typical - reduces DC error to <2.5 mV in unity-gain buffer applications at gain = 10. |
| Input Bias Current | 150 fA typical - preserves signal integrity in photodiode and high-impedance pH electrode front-ends. |
| CMRR | 85 dB min at 0–5 V common-mode range (5 V supply) - rejects power supply ripple and noise in single-supply instrumentation. |
| Output Swing | Within 10 mV of rails at RL = 25 kΩ (5 V supply) - maximizes dynamic range in ADC driver stages. |
| Gain-Bandwidth Product | 50 kHz - supports stable DC-coupled amplification up to ~5 kHz with gain = 10. |
| ESD Tolerance | 2.0 kV HBM - meets basic handling requirements without requiring special ESD workstations. |
Pinout & Package
LMC6464BIMX is supplied in a 14-pin SOIC package (Package Drawing D), with thermal resistance θJA = 126°C/W. This surface-mount package supports automated assembly and offers improved thermal performance over PDIP variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier A) | Accepts differential signal input; supports rail-to-rail common-mode range down to −0.2 V at 5 V supply. |
| 2 | Non-inverting input (Amplifier A) | High-impedance node (>10 TΩ); requires guard ring layout for leakage-sensitive applications. |
| 3 | Output (Amplifier A) | Delivers rail-to-rail output swing; capable of sourcing/sinking ≥19 mA at 5 V supply. |
| 4 | Ground / Negative Supply | Reference for single-supply operation; must be low-impedance to maintain PSRR >80 dB. |
| 5 | Non-inverting input (Amplifier B) | Independent high-Z input; usable in parallel-channel sensor conditioning without crosstalk. |
| 6 | Inverting input (Amplifier B) | Configurable for precision gain-setting with external resistors; compatible with CMRR trim networks. |
| 7 | Output (Amplifier B) | Electrically isolated output stage; maintains 130 Ω sink impedance at 5 V for predictable load interaction. |
| 8 | Positive Supply | Accepts 3.0–15.5 V; quiescent current remains stable across full operating voltage range. |
| 9 | Inverting input (Amplifier C) | Supports multi-channel instrumentation topologies; shares same input specs as Pins 1 and 6. |
| 10 | Non-inverting input (Amplifier C) | Enables three-op-amp in-amp designs; common-mode rejection unaffected by channel count. |
| 11 | Output (Amplifier C) | Delivers identical AC/DC performance to other outputs; no performance degradation in quad configuration. |
| 12 | Non-inverting input (Amplifier D) | Provides fourth independent channel for multi-sensor systems or redundant signal paths. |
| 13 | Inverting input (Amplifier D) | Compatible with gain-trim resistor networks; matches input capacitance (3 pF) across all channels. |
| 14 | Output (Amplifier D) | Final output channel; maintains 85 dB CMRR and 0.25 mV VOS matching across temperature. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micropower rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (550 μA/amplifier), lower CMRR (75 dB), wider GBW (6.4 MHz) | Better for AC-coupled audio or higher-frequency sensor signals; unsuitable for multi-year battery life targets | Select TLV2464IDR only when bandwidth >100 kHz is required and power budget allows ≥25× increase. |
| OPA2333AIDR | Zero-drift architecture, 0.02 μV/°C offset drift, 17 μA/amplifier, 350 kHz GBW | Superior DC accuracy for precision weigh scales or thermopile amplifiers; higher cost and complexity | Choose OPA2333AIDR when long-term offset stability over temperature is critical and 350 kHz bandwidth suffices. |
Compared with TLV2464IDR and OPA2333AIDR, LMC6464BIMX uniquely balances ultra-low power (20 μA), rail-to-rail I/O, and 85 dB CMRR in a cost-effective SOIC-14 package - making it optimal for multi-channel, battery-constrained instrumentation where moderate bandwidth suffices.

FAQ
What is the maximum supply voltage rating for LMC6464BIMX?
The LMC6464BIMX has an absolute maximum supply voltage (V+ − V−) of 16 V. Its recommended operating range is 3.0 V to 15.5 V for single-supply use or ±1.5 V to ±7.75 V in split-supply configurations. Operation above 15.5 V risks permanent damage, and short-circuiting the output to V+ is prohibited when V+ exceeds 13 V to ensure reliability. LMC6464BIMX maintains specified performance across this full range.
Does LMC6464BIMX support true rail-to-rail input and output operation?
Yes, LMC6464BIMX supports rail-to-rail input common-mode voltage range extending 0.2 V beyond both supply rails, and rail-to-rail output swing within 10 mV of each rail at 5 V supply with 25 kΩ load. This is confirmed in the Electrical Characteristics table for VO (Output Swing) and VCM (Input Common-Mode Voltage Range) parameters. The device achieves this using complementary CMOS input and output stages, validated across temperature and supply conditions.
What is the input bias current specification for LMC6464BIMX, and why does it matter?
LMC6464BIMX specifies a typical input bias current of 150 fA, with a maximum of 10 pA across temperature. This ultra-low value is critical when interfacing with high-impedance sources such as photodiodes, pH electrodes, or piezoelectric sensors - where even nanoamp-level currents would introduce significant voltage errors. At 150 fA, a 10 GΩ source adds only 1.5 mV offset, preserving signal fidelity in precision analog front-ends.
Can LMC6464BIMX drive capacitive loads, and what is its rated limit?
LMC6464BIMX can typically drive up to 200 pF capacitive load at unity gain with 5 V supply without oscillation. For larger loads (e.g., 300 pF), TI recommends resistive isolation (Figure 36) or feedback compensation (Figure 38) to maintain phase margin. Direct capacitive loading degrades stability due to interaction between output impedance (~110 Ω sourcing at 5 V) and load capacitance - a limitation explicitly characterized in the Capacitive Load Tolerance section of the datasheet.
Is LMC6464BIMX suitable for use in medical-grade portable devices?
Yes, LMC6464BIMX is widely deployed in FDA-cleared portable medical devices including ECG monitors and glucose meters. Its 0.25 mV input offset voltage, 85 dB CMRR, rail-to-rail I/O, and 20 μA/amplifier supply current meet key requirements for low-power, high-accuracy biosignal acquisition. TI provides full qualification data, including reliability testing per JESD22 and moisture sensitivity level (MSL) Level-1 rating, supporting compliance with IEC 60601-1 essential performance criteria.
