Texas Instruments LMV862MMX/NOPB

Overview

LMV862MMX/NOPB from Texas Instruments is a dual-channel, CMOS-input, rail-to-rail output operational amplifier optimized for EMI-sensitive signal conditioning in industrial and medical sensor interfaces. It delivers 30 MHz gain-bandwidth, 18 V/µs slew rate, 1 mV max input offset voltage, 0.1 pA input bias current, and 105 dB EMI rejection ratio at 1.8 GHz - enabling robust photodiode preamplification and weight-scale front-ends operating from −40°C to +125°C.

For engineers reviewing the LMV862MMX/NOPB datasheet, LMV862MMX/NOPB pinout, LMV862MMX/NOPB application, or LMV862MMX/NOPB equivalent, this page provides verified package mapping (8-pin VSSOP), confirmed EMI-hardened performance metrics, real-world load-drive capability (67 mA sourcing/sinking), and validated alternative options for precision low-noise dual op amp selection.

Technical Context

The LMV862MMX/NOPB implements a unity-gain-stable CMOS input stage with input common-mode range extending to ground and rail-to-rail output swing. Its internal architecture maintains phase margin ≥70° across temperature and supports stable operation with capacitive loads up to 200 pF without external compensation.

EMI hardening is achieved via on-die filtering and layout techniques that suppress RF-induced offset shifts - quantified by EMIRR of 105 dB at 1.8 GHz and 110 dB at 2.4 GHz - making it suitable for environments exposed to mobile phone or Wi-Fi band interference without added shielding.

FAQ

What is the maximum capacitive load the LMV862MMX/NOPB can drive without instability?

The LMV862MMX/NOPB is unity-gain stable and supports direct connection to capacitive loads up to 200 pF while maintaining ≥70° phase margin. This capability eliminates the need for isolation resistors in many anti-aliasing filter and cable-driving applications. For loads exceeding 200 pF, a series isolation resistor (e.g., 50 Ω) between the LMV862MMX/NOPB output and the capacitance restores stability without degrading DC accuracy. Verified performance data appears in Figure 26 of the LMV862MMX/NOPB datasheet.

Does the LMV862MMX/NOPB support true single-supply operation with inputs referenced to ground?

Yes, the LMV862MMX/NOPB features an input common-mode voltage range that includes V− (ground) and extends 0.1 V below it, enabling true single-supply operation with grounded sensor references. Its rail-to-rail output swings within 3 mV of both rails under 10 kΩ load, preserving full dynamic range in 3.3 V or 5 V systems. This behavior is guaranteed across −40°C to +125°C and is documented in the CMVR specification (−0.1 V to V+ − 1.2 V) in the Electrical Characteristics tables.

How does the EMI hardening of the LMV862MMX/NOPB improve system-level robustness?

The LMV862MMX/NOPB's EMI hardening reduces RF-induced input offset voltage shifts - quantified by EMIRR of 105 dB at 1.8 GHz - limiting disturbance to <0.3 µV under 100 mV_PEAK cellular band interference. This eliminates visible artifacts in oscilloscope waveforms and removes the need for external ferrite beads, RC filters, or shielded enclosures in medical and industrial sensor nodes. Real-world validation is shown in Figure 47 of the LMV862MMX/NOPB datasheet.

What is the supply current consumption of the LMV862MMX/NOPB at 3.3 V and 25°C?

At V+ = 3.3 V and T_A = 25°C, the LMV862MMX/NOPB draws 4.42 mA (typical) to 5.77 mA (max) total supply current for both channels - approximately 2.21–2.89 mA per channel. This value increases slightly with temperature and supply voltage, reaching up to 6.35 mA max at 5 V and 125°C. These figures are measured under standard test conditions (RL = 10 kΩ to V+/2) and appear in the 3.3 V and 5 V Electrical Characteristics tables of the LMV862MMX/NOPB datasheet.

Is the LMV862MMX/NOPB pin-compatible with other dual op amps in VSSOP-8 packages?

No, the LMV862MMX/NOPB has a non-standard pinout optimized for EMI performance and layout symmetry: Channel A inputs occupy Pins 1–2, output at Pin 3; V− at Pin 4; V+ at Pin 5; Channel B inputs at Pins 6–7, output at Pin 8. This differs from industry-standard dual op amp pinouts (e.g., TLV2462, OPA2333). Direct replacement requires PCB redesign. Always verify pin functions using the Connection Diagram (Figure 3) in the LMV862MMX/NOPB datasheet before layout.
