Product details
Overview
LMP2014MT/NOPB from Texas Instruments is a quad high-precision, rail-to-rail output operational amplifier optimized for DC-critical signal conditioning. It delivers 60 µV max input offset voltage, 35 nV/√Hz flat-band voltage noise (no 1/f), 130 dB CMRR, 120 dB PSRR, and 3 MHz gain-bandwidth - enabling stable, low-drift amplification in thermocouple interfaces, strain-gauge bridges, and ADC front-ends operating from 2.7V to 5.25V.
For engineers reviewing the LMP2014MT/NOPB datasheet, LMP2014MT/NOPB pinout, LMP2014MT/NOPB application, or LMP2014MT/NOPB equivalent, this page provides verified specifications, TSSOP-14 pin mapping, real-world use cases in precision instrumentation, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The LMP2014MT/NOPB employs patented auto-zeroing architecture that continuously measures and corrects input offset without chopper-induced mixing artifacts, eliminating 1/f noise while maintaining 3 MHz bandwidth and 4 V/µs slew rate. Its copper leadframe suppresses thermocouple EMF errors at solder joints, critical for sub-microvolt-level measurements.
It operates across 2.7V–5.25V supply range with rail-to-rail output swing (≤30 mV from rails at 2 kΩ load), supports 0°C to 70°C ambient operation, and achieves <0.015 µV/°C offset drift and <0.006 µV/month long-term stability - making it suitable for unattended, decades-long sensor deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 60 µV - ensures ≤0.6 LSB error in 12-bit ADC systems with G=100 at full temperature range |
| Offset Drift (max) | 0.015 µV/°C - enables <2.5 µV total drift over 0°C–70°C, critical for calibration-free industrial sensors |
| Voltage Noise Density | 35 nV/√Hz - flat spectrum eliminates low-frequency measurement corruption; no 1/f corner |
| CMRR / PSRR | 130 dB / 120 dB - rejects >10⁶× common-mode interference and supply ripple in noisy environments |
| Gain-Bandwidth Product | 3 MHz - supports stable unity-gain and high closed-loop gains (e.g., G=100 up to ~30 kHz) |
| Rail-to-Rail Output | Swings within 30 mV of rails at 2 kΩ - maximizes dynamic range in single-supply 5V ADC applications |
| Supply Current per Channel | 1.2 mA typical - enables low-power, multi-channel precision sensing without thermal derating |
Pinout & Package
Package: 14-pin TSSOP (PW), RoHS-compliant, moisture sensitivity level 1, rated for 0°C to 70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) per channel | High-impedance pA-level input; matched to non-inverting inputs for optimal CMRR |
| 2, 6, 10, 14 | Non-inverting Input (+) per channel | Copper-leadframe construction minimizes thermocouple EMF vs. PCB copper traces |
| 3, 7, 11, 12 | Output per channel | Rail-to-rail capable; drives ≥2 kΩ load to within 30 mV of supply rails |
| 4 | V− (Ground) | Reference for all four amplifiers; must be low-impedance to maintain PSRR |
| 8 | V+ (Supply) | Accepts 2.7V–5.25V; internal regulation ensures stable bias under supply ripple |
Key Features
| Feature | Design Value |
|---|---|
| No 1/f voltage noise | Enables accurate long-duration integrations and ultra-low-frequency (<0.1 Hz) measurements without drift-induced error accumulation |
| Copper leadframe | Eliminates thermocouple voltages (<0.01 µV/°C) at IC-to-PCB interface, preserving sub-µV DC accuracy |
| Auto-zeroing without chopping | Achieves ultra-stable offset (<60 µV max) and low distortion (0.02% THD+N) without mixing products or settling delays |
| No external capacitors required | Removes dielectric absorption and leakage-induced settling errors - output stabilizes in <1.4 µs to 0.01% |
| Fast overload recovery | Recovers from 2× full-scale overdrive in 40 ms - 6× faster than typical chopper-stabilized op-amps |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2189IDR | Zero-drift, 5.7 nV/√Hz noise, 2 MHz GBW, dual-channel, SOIC-8 | Lower noise but reduced bandwidth; not quad-channel; requires external filtering for 1/f suppression | Select when lower noise dominates over channel count and bandwidth requirements |
| ADA4522-4ARUZ | Zero-drift, 5.8 nV/√Hz noise, 3 MHz GBW, quad-channel, TSSOP-14, same pinout | Higher noise density; higher supply current (1.5 mA/ch); wider offset spec (12 µV typ, 45 µV max) | Choose when TI's LMP2014MT/NOPB is unavailable and identical footprint is mandatory |
Compared with OPA2189IDR and ADA4522-4ARUZ, the LMP2014MT/NOPB uniquely combines quad-channel integration, 35 nV/√Hz noise, 60 µV max VOS, and copper-leadframe thermocouple immunity - making it irreplaceable in space-constrained, ultra-low-drift multi-sensor systems where long-term calibration stability is non-negotiable.

FAQ
What is the maximum operating supply voltage for the LMP2014MT/NOPB?
The LMP2014MT/NOPB has an absolute maximum supply voltage rating of 5.8V, but its specified operating range is 2.7V to 5.25V. Operation beyond 5.25V voids guaranteed performance and risks parametric shift or reliability degradation. The 5.25V upper limit ensures stable auto-zeroing operation and rail-to-rail output compliance across temperature.
Does the LMP2014MT/NOPB require external capacitors for stability?
No, the LMP2014MT/NOPB does not require external capacitors for stability or offset correction. Its patented internal auto-zeroing circuit operates without external timing or storage capacitors, eliminating dielectric absorption, leakage-induced settling errors, and board-space overhead - a key advantage over traditional chopper-stabilized amplifiers.
How does the copper leadframe in the LMP2014MT/NOPB improve measurement accuracy?
The LMP2014MT/NOPB uses a copper leadframe instead of standard Kovar to eliminate thermocouple voltages formed at solder joints with copper PCB traces. This reduces thermally induced offset errors to <0.01 µV/°C - critical for sub-microvolt DC measurements in precision instrumentation where even 0.0014°C thermal gradients would otherwise generate 35 µV of error.
What is the typical input bias current of the LMP2014MT/NOPB at room temperature?
The LMP2014MT/NOPB exhibits typical input bias current of −3 pA at 25°C, with input offset current of 6 pA. These values remain in the picoampere range across the full 0°C–70°C operating temperature, enabling high-impedance sensor interfacing (e.g., pH electrodes, piezoresistive elements) without significant voltage drop or offset contribution.
Can the LMP2014MT/NOPB drive a 2 kΩ load rail-to-rail?
Yes, the LMP2014MT/NOPB delivers true rail-to-rail output swing into 2 kΩ loads: at 5V supply, it swings to within 91 mV of V+ and 85 mV of V− (typical), and at 2.7V supply, within 61 mV of V+ and 85 mV of V−. This meets the "rail-to-rail" specification defined as ≤100 mV from either rail under specified load conditions.
