Product details
Overview
LMP2022MM/NOPB from Texas Instruments is a dual zero-drift, low-noise, EMI-hardened operational amplifier designed for precision sensor signal conditioning in high-accuracy analog front-ends. It delivers ±5 µV max input offset voltage, −0.004 µV/°C typical offset drift, 11 nV/√Hz input voltage noise at 1 kHz (AV = 1000), 5 MHz gain-bandwidth product, and rail-to-rail output swing - enabling stable 24-bit bridge and thermocouple amplifier designs operating from 2.2 V to 5.5 V supply.
For engineers reviewing the LMP2022MM/NOPB datasheet, LMP2022MM/NOPB pinout, LMP2022MM/NOPB application, or LMP2022MM/NOPB equivalent, key selection criteria include ultra-low DC error budget compatibility, EMI rejection at 900–2400 MHz, dual-channel crosstalk isolation (>150 dB), and VSSOP-8 package suitability for space-constrained instrumentation PCBs.
Technical Context
The LMP2022MM/NOPB employs proprietary continuous auto-zero correction to eliminate 1/f noise and suppress input offset drift, achieving near-zero long-term DC error without external calibration. Its on-chip EMI filtering rejects RF interference at cellular and Wi-Fi frequencies (400–2400 MHz) via integrated input and supply-line filters, preserving signal integrity in noisy industrial environments.
This dual op-amp operates with matched channel performance: identical input bias current (±25 pA), common-mode voltage range (−0.2 V to 4.2 V at 5 V supply), and cross-talk rejection (150 dB at 1 kHz). Its 160 dB open-loop gain ensures <0.001% gain error in 100× instrumentation amplifier configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (Max) | ±5 µV - Enables sub-10 ppm DC accuracy in 10 V full-scale systems without trimming. |
| Offset Drift (Typ) | −0.004 µV/°C - Supports uncalibrated operation across −40°C to +125°C industrial temperature range. |
| Input Voltage Noise | 260 nVPP (0.1–10 Hz) - Suitable for low-frequency precision weigh scales and strain gauge interfaces. |
| EMI Rejection Ratio | 82 dB at 2400 MHz - Reduces need for external RF shielding in wireless-adjacent sensor nodes. |
| Gain-Bandwidth Product | 5 MHz - Supports stable closed-loop gain ≥100 up to ~40 kHz with 60° phase margin. |
| Supply Range | 2.2 V to 5.5 V - Compatible with single-cell Li-ion, 3.3 V logic, and 5 V legacy systems. |
| Output Swing | 83 mV from rail (RL = 10 kΩ, 5 V) - Delivers >98% of full-scale dynamic range in ratiometric ADC buffers. |
Pinout & Package
Package: 8-pin VSSOP (DGK), body size 3.00 mm × 3.00 mm, 0.65 mm pitch, exposed pad optional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT A (Pin 1) | Output, Channel A | Low-impedance buffered output capable of sourcing/sinking 50 mA; rail-to-rail swing supports wide dynamic range. |
| –IN A (Pin 2) | Inverting Input, Channel A | Differential input node with 12 pF input capacitance; matched to +IN A for optimal CMRR in feedback networks. |
| +IN A (Pin 3) | Non-Inverting Input, Channel A | High-impedance input (±25 pA bias current); used for reference-sensing or non-inverting gain stages. |
| V– (Pin 4) | Negative Supply | Low-impedance ground or negative rail connection; shared by both amplifiers; requires local 0.1 µF decoupling. |
| +IN B (Pin 5) | Non-Inverting Input, Channel B | Independent input for second signal path; electrically isolated from Channel A with 150 dB crosstalk rejection. |
| –IN B (Pin 6) | Inverting Input, Channel B | Matched to Pin 2; enables dual independent instrumentation amp configurations or differential output drivers. |
| OUT B (Pin 7) | Output, Channel B | Fully independent output; supports simultaneous dual-sensor readout or active filter topologies. |
| V+ (Pin 8) | Positive Supply | Highest potential supply rail; powers both channels; EMI filtering integrated internally on this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Continuous auto-zero correction eliminates 1/f noise and reduces long-term drift to <0.02 µV/°C max - critical for unattended sensor logging. |
| EMI-hardened inputs | On-chip RF filters provide >60 dB rejection at 900 MHz and >80 dB at 2.4 GHz - removes need for external ferrites or shielded enclosures. |
| Ultra-low input bias current | ±25 pA typical enables use with high-impedance sources (e.g., pH electrodes, piezoresistive sensors) without significant offset error. |
| Rail-to-rail output | Swings within 83 mV of rails at 5 V supply - maximizes ADC utilization and simplifies level-shifting in mixed-signal systems. |
| Dual-channel isolation | 150 dB crosstalk rejection at 1 kHz ensures independent operation of both amplifiers - essential for dual-bridge or stereo sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2189IDR | Lower input voltage noise (5.2 nV/√Hz), higher GBW (12 MHz), but no integrated EMI filtering; 0.005 µV/°C drift. | Better for wideband sensor interfaces (e.g., ultrasonic transducers); less robust in RF-dense environments without added filtering. | Select when bandwidth >5 MHz is required and board-level EMI mitigation is feasible. |
| AD8629ARZ-REEL7 | Similar zero-drift architecture, 0.005 µV/°C drift, but lower EMIRR (55 dB @ 900 MHz); SOIC-8 only, no VSSOP option. | Suitable for cost-sensitive industrial controls where RF immunity is secondary; lacks VSSOP footprint for compact layouts. | Choose for legacy SOIC designs or when VSSOP packaging is not required. |
Compared with OPA2189IDR and AD8629ARZ-REEL7, the LMP2022MM/NOPB uniquely combines VSSOP-8 packaging, on-die EMI hardening up to 2400 MHz, and guaranteed ±5 µV offset across temperature - making it the preferred choice for miniaturized, field-deployed instrumentation where RF resilience and long-term DC stability are non-negotiable.

FAQ
What is the maximum operating temperature for the LMP2022MM/NOPB?
The LMP2022MM/NOPB is rated for continuous operation from −40°C to +125°C ambient temperature. This extended range is validated per JEDEC JESD22-A104 and supported by its ±0.02 µV/°C max offset drift specification - making it suitable for under-hood automotive and industrial control cabinet deployments where thermal cycling is severe.
Does the LMP2022MM/NOPB require external capacitors for EMI suppression?
No. The LMP2022MM/NOPB integrates on-die EMI filters on both input pins and power supply pins, delivering >82 dB rejection at 2400 MHz without external components. This eliminates the need for discrete RC filters or ferrite beads in most applications, reducing BOM count and PCB area while improving layout robustness.
Can the LMP2022MM/NOPB drive a 10 kΩ load rail-to-rail at 5 V supply?
Yes. At 5 V supply and RL = 10 kΩ, the LMP2022MM/NOPB delivers rail-to-rail output swing within 83 mV of each rail (high) and 65 mV (low), per TI's SNOSAY9G datasheet Section 6.6. This ensures >98% usable dynamic range when driving precision ADCs or downstream comparators.
Is the LMP2022MM/NOPB pin-compatible with other VSSOP-8 dual op-amps?
The LMP2022MM/NOPB uses standard VSSOP-8 pinout (DGK package) matching industry conventions: Pin 1 = OUT A, Pin 2 = –IN A, Pin 3 = +IN A, Pin 4 = V–, Pin 5 = +IN B, Pin 6 = –IN B, Pin 7 = OUT B, Pin 8 = V+. However, functional compatibility depends on internal architecture - it is not a drop-in replacement for non-zero-drift or non-EMI-hardened parts due to differing noise, drift, and RF rejection behavior.
What is the typical supply current per channel for the LMP2022MM/NOPB at 25°C?
The typical supply current per channel for the LMP2022MM/NOPB is 1.1 mA at TA = 25°C and VS = 5 V, as specified in Section 6.6 of the SNOSAY9G datasheet. Total device current is therefore ~2.2 mA, enabling multi-year battery life in low-duty-cycle sensor nodes powered from CR2032 or similar cells.
