Product details
Overview
LMP2022MME/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 operates from 2.2 V to 5.5 V supply - enabling use in battery-powered weigh scales and bridge-based pressure transducers.
For engineers reviewing the LMP2022MME/NOPB datasheet, LMP2022MME/NOPB pinout, LMP2022MME/NOPB application, or LMP2022MME/NOPB equivalent, key selection criteria include ultra-low DC error budget compatibility, EMI rejection at 900–2400 MHz, rail-to-rail output swing within 83 mV of rails (RL = 10 kΩ, VS = 5 V), and dual-channel isolation for differential sensor interfaces requiring >140 dB cross-talk rejection.
Technical Context
The LMP2022MME/NOPB employs proprietary continuous auto-zero correction to eliminate 1/f noise and suppress input offset drift, achieving near-zero long-term DC drift without external calibration. Its on-chip EMI filtering targets RF interference at cellular/Wi-Fi frequencies (400–2400 MHz), delivering up to 82 dB EMIRR at 2.4 GHz under 5 V supply.
This dual op-amp integrates matched input pairs with 150 dB channel-to-channel cross-talk rejection and supports rail-to-rail output swing while maintaining 160 dB open-loop gain and 139 dB CMRR - critical for high-gain, low-frequency instrumentation where signal integrity must be preserved across temperature and supply variations.

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 | Better for wideband precision applications; less robust in RF-noisy environments | Select when bandwidth >5 MHz is required and board-level EMI mitigation is feasible |

FAQ
What is the maximum input offset voltage specification for LMP2022MME/NOPB?
The LMP2022MME/NOPB has a maximum input offset voltage of ±5 µV across the full operating temperature range (−40°C to +125°C), as specified in the Electrical Characteristics table for 5 V supply conditions. This value is critical for minimizing gain error in high-precision, high-gain sensor amplifier stages where even sub-microvolt offsets directly impact measurement accuracy.
Does LMP2022MME/NOPB support single-supply operation?
Yes, LMP2022MME/NOPB supports true single-supply operation from 2.2 V to 5.5 V. Its input common-mode voltage range extends to 0 V (with V− grounded) and its rail-to-rail output swings within 83 mV of V+ and 65 mV of V− at 5 V supply, enabling direct interfacing with low-voltage ADCs and microcontrollers without level-shifting circuitry.
How does the EMI rejection capability of LMP2022MME/NOPB compare at different RF frequencies?
LMP2022MME/NOPB provides frequency-dependent EMI rejection: 58 dB at 400 MHz, 64 dB at 900 MHz, 72 dB at 1800 MHz, and 82 dB at 2400 MHz (measured per EMIRR definition with 100 mVP RF peak). This progressive improvement reflects its on-chip filtering design optimized for modern wireless bands including GSM, UMTS, and Wi-Fi/Bluetooth.
What is the typical supply current per amplifier for LMP2022MME/NOPB at 25°C and 5 V supply?
The typical supply current per amplifier for LMP2022MME/NOPB is 1.1 mA at 25°C and 5 V supply, as confirmed in Section 6.6 of the datasheet. At full temperature range (−40°C to +125°C), the maximum is 1.57 mA per amplifier - enabling efficient power budgeting in dual-channel, battery-powered instrumentation designs.
Is LMP2022MME/NOPB pin-compatible with other dual op-amps in VSSOP-8 packages?
No, LMP2022MME/NOPB is not pin-compatible with generic dual op-amps in VSSOP-8. Its pinout (OUT A, –IN A, +IN A, V–, +IN B, –IN B, OUT B, V+) is specific to TI's LMP202x family and differs from industry-standard configurations like the LMV358 or TLV2372. Board layout must follow the DGK package pin mapping provided in the datasheet.
