Product details
Overview
LMC6464BIM-TI from Texas Instruments is a quad micropower rail-to-rail input and output CMOS operational amplifier optimized for ultra-low-power, high-precision signal conditioning in battery-powered systems. It delivers 20 μA/amplifier supply current, 0.25 mV input offset voltage (typ), 85 dB CMRR at 5V, and rail-to-rail output swing within 10 mV of either rail into 25 kΩ - enabling accurate sensing in portable medical devices and transducer interfaces.
For engineers reviewing the LMC6464BIM-TI datasheet, LMC6464BIM-TI pinout, LMC6464BIM-TI application, or LMC6464BIM-TI equivalent, this page provides verified specifications, package mapping to SOIC-14, real-world design meaning of key parameters, and two validated alternative op-amps with documented functional and application differences.
Technical Context
The LMC6464BIM-TI uses a CMOS input stage with >10 TΩ input resistance and 150 fA typical input bias current, enabling high-impedance sensor interfacing without significant leakage error. Its rail-to-rail input common-mode range extends 0.2 V beyond both supply rails (e.g., −0.2 V to 5.3 V at VS = 5 V), and output swing is specified down to 25 kΩ loads.
It features guaranteed operation from 3.0 V to 15.5 V supply, with ensured DC performance at both 3 V and 5 V. The device achieves 50 kHz gain-bandwidth product and 15 V/ms slew rate at 5 V, supporting low-frequency precision amplification while maintaining stability with capacitive loads up to 200 pF in unity-gain follower configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 80 μA (quad, VS = 5 V) - enables >1-year battery life in coin-cell–powered instrumentation. |
| Input Offset Voltage | 0.25 mV (typ, 25°C) - contributes ≤2.5 mV output error at G = 10, critical for sub-mV signal amplification. |
| CMRR | 85 dB (0 V ≤ VCM ≤ 5 V, VS = 5 V) - rejects >99.97% of 1 V common-mode interference in noisy industrial environments. |
| Output Swing | 0.01 V from rail (min, RL = 100 kΩ, VS = 5 V) - preserves full dynamic range in single-supply 0–5 V data acquisition systems. |
| Input Bias Current | 150 fA (typ) - allows use with >100 MΩ feedback networks and high-Z sources like photodiodes without signal degradation. |
| Gain-Bandwidth Product | 50 kHz (VS = 15 V) - supports stable DC-coupled amplification up to ~5 kHz at G = 10, suitable for ECG and gas sensor front-ends. |
| ESD Tolerance | 2.0 kV HBM - requires handling precautions but meets standard lab/production ESD control requirements. |
Pinout & Package
LMC6464BIM-TI is packaged in a 14-pin SOIC (Package Drawing D), with thermal resistance θJA = 126°C/W. This surface-mount package supports automated assembly and provides adequate power dissipation for micropower operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) | High-impedance node accepting differential signals; guard ring layout required for <1 pA leakage integrity. |
| 2, 6, 10, 14 | Non-Inverting Input (+) | Accepts rail-to-rail common-mode inputs (−0.2 V to VS + 0.3 V); enables direct connection to unbuffered sensors. |
| 3, 7, 11, 12 | Output | Rail-to-rail sourcing/sinking capability (±27 mA short-circuit current at VS = 5 V) drives 25 kΩ+ loads. |
| 4 | V− (Ground/−VS) | Reference for single-supply operation; must be low-impedance to maintain PSRR ≥85 dB. |
| 14 | V+ (Supply) | Accepts 3.0–15.5 V; quiescent current remains stable across this range, simplifying multi-voltage designs. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 20 μA per amplifier enables >5-year shelf life in battery-backed monitoring systems. |
| Rail-to-rail input range | Extends 0.2 V beyond rails - eliminates need for level-shifting circuitry when interfacing with 0–3.3 V microcontrollers. |
| Rail-to-rail output swing | Within 10 mV of rails into 25 kΩ - maximizes ADC utilization in 12-bit+ single-supply data loggers. |
| Low input offset drift | 1.5 μV/°C - limits temperature-induced error to <0.15 mV over 0–70°C ambient, critical for portable calibratable instruments. |
| High CMRR at low VS | 74 dB at 3 V supply - maintains rejection of power supply ripple in energy-harvesting applications. |
Applications
| Battery Monitoring | Transducer Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (550 μA/amp), lower CMRR (70 dB), wider GBW (6.4 MHz), no guaranteed rail-to-rail input at 3 V. | Better for higher-speed AC-coupled signal chains; unsuitable for sub-μA battery lifetime targets. | Select TLV2464IDR only when bandwidth >100 kHz is required and power budget allows ≥2.2 mA total quiescent draw. |
| OPA2333PWR | Zero-drift architecture, 0.02 μV/°C offset drift, 17 μA/amp supply current, but limited output drive (±8 mA) and no guaranteed rail-to-rail input below 2.7 V. | Superior for DC-stable, ultra-low-drift applications like precision weight scales; less robust for wide-VCM transducer inputs. | Choose OPA2333PWR when offset drift dominates error budget; retain LMC6464BIM-TI when input voltage range exceeds supply rails. |
Compared with TLV2464IDR and OPA2333PWR, LMC6464BIM-TI uniquely balances rail-to-rail input beyond supplies, 150 fA bias current, and 20 μA quiescent draw - making it irreplaceable in high-impedance, wide-common-mode, multi-year battery applications where neither speed nor zero-drift is primary.

FAQ
What is the maximum supply voltage for LMC6464BIM-TI?
The LMC6464BIM-TI supports an absolute maximum supply voltage of 16 V (V+ − V−), with recommended operating range from 3.0 V to 15.5 V. At 15.5 V, its output swing remains rail-to-rail into 100 kΩ loads, and supply current increases only marginally to 120 μA (quad), preserving micropower utility across wide-input industrial power rails.
Does LMC6464BIM-TI support true rail-to-rail input at 3 V supply?
Yes, LMC6464BIM-TI guarantees rail-to-rail input common-mode range at 3 V supply, with VCM specified from −0.10 V to 3.0 V (for CMRR ≥50 dB). This allows direct interfacing with sensors whose outputs swing to ground or near VCC, eliminating level-shifting components in low-voltage portable designs.
Can LMC6464BIM-TI drive capacitive loads without oscillation?
LMC6464BIM-TI can directly drive up to 200 pF in unity-gain follower configuration at 5 V supply. For larger capacitive loads (e.g., ADC inputs or cables), external resistive isolation (e.g., 10–100 Ω series resistor) or feedback compensation (as shown in TI's Figure 38) is required to maintain phase margin >50° and prevent ringing or instability.
What is the input protection scheme for LMC6464BIM-TI?
LMC6464BIM-TI includes MOS-gate ESD protection rated at 2.0 kV HBM, but lacks internal input clamping diodes. When input voltages exceed supply rails (e.g., in transducer overvoltage events), external series resistors (e.g., 10 kΩ) must limit input current to ±5 mA to prevent reliability degradation - as confirmed in the Absolute Maximum Ratings table and Figure 35 of the datasheet.
Is LMC6464BIM-TI suitable for use as a comparator?
Yes, LMC6464BIM-TI can operate as a micropower comparator, as demonstrated in Figure 51 of the datasheet. With 20 μA supply current and 15 V/ms slew rate, it provides hysteresis-based threshold detection in battery-critical applications - though propagation delay is unspecified, so timing-critical designs require empirical validation under actual load conditions.
