Product details
Overview
LMC6024IMX/NOPB from Texas Instruments is a low-power CMOS quad operational amplifier designed for high-impedance signal conditioning in single-supply (4.75–15.5 V) or dual-supply systems. It delivers 120 dB voltage gain into 100 kΩ, ultra-low 40 fA input bias current, and rail-to-rail input common-mode range extending to V− - enabling precision buffering and integration in medical instrumentation and industrial controls.
For engineers reviewing the LMC6024IMX/NOPB datasheet, LMC6024IMX/NOPB pinout, LMC6024IMX/NOPB application, or LMC6024IMX/NOPB equivalent, key selection criteria include micropower operation (240 μA per amplifier), 0.11 V/μs slew rate, 0.35 MHz gain-bandwidth product, and SOIC-14 package compatibility with high-impedance PCB layout requirements.
Technical Context
The LMC6024IMX/NOPB uses a compound integrator-based output stage without a traditional unity-gain buffer, enabling rail-to-rail output swing while maintaining stability into 500 Ω loads. Its topology includes dual feed-forward compensation (Cf and Cff) and a push-pull output stage optimized for both sourcing and sinking current.
It achieves ultra-low input bias current via silicon-gate CMOS process technology and supports stable operation with capacitive loads up to ~100 pF when paired with series output resistors (50–100 Ω) and feedback capacitors (5–10 pF), as verified in TI's application hints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.75 V to 15.5 V - supports single-supply operation down to 5 V and full performance up to 15 V. |
| Input Bias Current | 40 fA typical - enables accurate long-term integration and photodiode current-to-voltage conversion without leakage-induced drift. |
| Input Offset Voltage Drift | 2.5 μV/°C - ensures stable DC accuracy across −40°C to +85°C industrial temperature range. |
| Slew Rate | 0.11 V/μs - sufficient for 1 kHz low-distortion (<0.01%) signal amplification in sensor front-ends. |
| Gain-Bandwidth Product | 0.35 MHz - defines usable closed-loop bandwidth for unity-gain stable configurations up to ~350 kHz. |
| Common-Mode Input Range | Includes V− (down to −0.4 V at V+ = 5 V) - allows direct interfacing with ground-referenced sensors in single-supply systems. |
| Output Short-Circuit Current | ±18 mA - supports driving moderate loads such as ADC reference buffers or LED bias circuits without external limiting. |
Pinout & Package
LMC6024IMX/NOPB is housed in a 14-pin SOIC (Package D0014A), 3.9 mm wide, 1.75 mm max height, RoHS-compliant with Sn lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) | High-impedance node requiring guard ring layout; accepts input common-mode down to V−. |
| 2, 6, 10, 14 | Non-Inverting Input (+) | Same ultra-low bias current and common-mode range as inverting inputs; critical for high-Z sensor interfaces. |
| 3, 7, 11, 12 | Output | Rail-to-rail capable; sinks/sours ≥13 mA at V+ = 5 V; requires series resistor for >100 pF capacitive loads. |
| 4 | V− (Ground or Negative Supply) | Reference for all four amplifiers; input common-mode extends to this pin - essential for single-supply biasing. |
| 14 | V+ (Positive Supply) | Power rail for all amplifiers; maximum 15.5 V; thermal resistance θJA = 115°C/W in SOIC package. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower Operation | 240 μA total supply current (all four op amps) - enables battery-powered portable instrumentation with multi-year runtime. |
| Ultra-Low Input Bias Current | 40 fA typical - reduces error in high-impedance transducer interfaces (e.g., pH electrodes, piezoelectric sensors). |
| Rail-to-Rail Input Common-Mode Range | Extends to V− - eliminates need for level-shifting circuitry when interfacing with ground-referenced sources. |
| Stable into 500 Ω Loads | No phase inversion or oscillation with resistive loads ≥500 Ω - simplifies design of current-output DAC buffers and active filters. |
| Low Distortion | 0.01% THD+N at 1 kHz - preserves signal fidelity in audio preamplifier and medical ECG front-end applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad CMOS op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (550 μA), lower GBW (6.4 MHz), no V−-inclusive input range. | Better AC performance but unsuitable for true single-supply ground-sensing; requires ≥1.5 V headroom below V+. | Choose TLV2464IDR only when higher speed and drive capability outweigh micropower and rail-to-rail input needs. |
| OPA2333PWR | Zero-drift architecture, 0.02 μV/°C drift, but higher input bias current (200 pA) and limited output drive (±25 mA). | Superior DC precision for zero-drift-critical applications, but cannot replace LMC6024IMX/NOPB in ultra-high-Z (>1 GΩ) sensor paths. | Select OPA2333PWR where long-term DC stability dominates; avoid where femtoamp-level input leakage is mandatory. |
Compared with TLV2464IDR and OPA2333PWR, LMC6024IMX/NOPB uniquely balances femtoamp input bias, rail-to-rail input, micropower operation, and industrial temperature range - making it irreplaceable in battery-powered, high-impedance analog front-ends requiring decades-long calibration stability.

FAQ
What is the maximum capacitive load the LMC6024IMX/NOPB can drive without oscillation?
The LMC6024IMX/NOPB can drive up to ~100 pF capacitively without oscillation when configured as a unity-gain follower and using recommended compensation: a 50–100 Ω series resistor at the output and a 5–10 pF capacitor from inverting input to output. Uncompensated, instability may occur above ~30 pF depending on gain and layout. TI's Figure 22 and 24 confirm this behavior across temperature and supply conditions.
Does the LMC6024IMX/NOPB support true single-supply operation with input signals at ground potential?
Yes. The LMC6024IMX/NOPB features an input common-mode voltage range that includes V−, meaning it accepts inputs down to ground (0 V) when operated from a single +5 V supply. This is confirmed in the DC Electrical Characteristics table (VCM range: −0.4 V min at V+ = 5 V) and enables direct interfacing with ground-referenced sensors without level-shifting circuitry.
What is the guaranteed input offset voltage for LMC6024IMX/NOPB over temperature?
The LMC6024IMX/NOPB has a maximum input offset voltage of 11 mV over the full −40°C to +85°C operating temperature range, as specified in the DC Electrical Characteristics table under "LMC6024I" limits. At 25°C, the typical value is 1 mV, and the average drift is 2.5 μV/°C - allowing precise prediction of offset variation across ambient conditions.
Can LMC6024IMX/NOPB be used in a 3.3 V system?
No - the LMC6024IMX/NOPB is not characterized or guaranteed for operation at 3.3 V. Its minimum specified supply voltage is 4.75 V (per Operating Ratings), and electrical characteristics (e.g., output swing, gain) are only validated from 4.75 V to 15.5 V. For 3.3 V designs, consider TI's TLV2464 or OPA333 families instead.
How does the LMC6024IMX/NOPB achieve rail-to-rail output swing despite being a CMOS op amp?
The LMC6024IMX/NOPB achieves rail-to-rail output swing by omitting the traditional unity-gain buffer and taking output directly from a compound integrator stage with push-pull output transistors. As described in Application Hints (Figure 25), this architecture allows VO to reach within ~60 mV of V+ and ~40 mV of V− at V+ = 5 V with 100 kΩ load - verified in the Output Voltage Swing specifications.
