Product details
Overview
LMV852MMX/NOPB from Texas Instruments is a dual-channel, rail-to-rail output, CMOS-input operational amplifier optimized for EMI-hardened sensor signal conditioning in harsh RF environments. It delivers 8 MHz gain-bandwidth, 4.5 V/µs slew rate, 0.4 mA per channel supply current at 3.3 V, and 87 dB EMI rejection ratio at 1.8 GHz - enabling stable amplification of low-level piezoelectric or photodiode signals near cellular/Wi-Fi transceivers.
For engineers reviewing the LMV852MMX/NOPB datasheet, LMV852MMX/NOPB pinout, LMV852MMX/NOPB application, or LMV852MMX/NOPB equivalent, this page provides verified specifications, package-confirmed pin functions, real-world EMI-hardened use cases, and two validated alternative op amps with documented functional trade-offs for portable medical, industrial sensing, and battery-powered instrumentation designs.
Technical Context
The LMV852MMX/NOPB employs a CMOS input stage with 0.1 pA typical input bias current and −0.2 V to 3.8 V (at 5 V supply) input common-mode range including ground. Its unity-gain-stable architecture maintains ≥62° phase margin with capacitive loads up to 200 pF, eliminating need for external isolation resistors in most sensor buffer configurations.
EMI hardening is implemented via on-die filtering and layout techniques that suppress RF rectification at IN+ and IN−, yielding 87 dB EMIRR at 1.8 GHz - a measured parameter defined as 20·log(VRFpeak/ΔVOS) - directly quantifying offset voltage perturbation under RF stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 5.5 V - supports single-cell Li-ion (3.0–3.7 V) and USB-powered (5 V) systems without LDO. |
| GBW Product | 8 MHz - enables stable unity-gain buffering of signals up to ~1 MHz with <1% gain error. |
| Input Offset Voltage | ±1 mV max - ensures ≤10 mV output error in 10× gain sensor interfaces with 10 mV full-scale input. |
| EMI Rejection Ratio | 87 dB at 1.8 GHz - reduces RF-induced offset drift to <1 µV under 100 mVPK 1.8 GHz interference. |
| Output Drive | 30 mA short-circuit current - drives 10 kΩ loads to rail with <12 mV headroom and sustains 20 mA into 100 Ω. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive sensors and industrial process monitoring. |
| Input Noise Density | 11 nV/√Hz at 1 kHz - preserves SNR in DC-coupled photodiode preamps with bandwidths <100 kHz. |
Pinout & Package
LMV852MMX/NOPB is packaged in an 8-pin VSSOP (DGK0008A), 3.0 mm × 3.0 mm, 0.65 mm pitch, thermally enhanced surface-mount package with exposed thermal pad (not electrically connected). Pin 1 marked by beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Rail-to-rail sourcing/sinking node; connects directly to ADC input or next-stage filter without level-shifting. |
| 2 (−IN A) | Channel A inverting input | High-impedance node (0.1 pA bias); requires matched trace impedance to non-inverting input for CMRR optimization. |
| 3 (+IN A) | Channel A non-inverting input | Accepts common-mode voltages down to −0.2 V; enables single-supply sensor interfacing with grounded reference. |
| 4 (V−) | Negative supply | Ground reference for single-supply operation; must be low-impedance path to minimize PSRR degradation. |
| 5 (+IN B) | Channel B non-inverting input | Independent high-Z input; allows dual-sensor differential pair or separate signal paths without crosstalk. |
| 6 (−IN B) | Channel B inverting input | Matched to Pin 2; channel separation >100 dB at 1 MHz ensures minimal inter-channel coupling in shared PCB layouts. |
| 7 (OUT B) | Channel B output | Electrically isolated from OUT A; supports independent gain stages or redundant signal paths. |
| 8 (V+) | Positive supply | Accepts 2.7–5.5 V; internal regulation ensures stable biasing across supply range; decoupling capacitor required. |
Key Features
| Feature | Design Value |
|---|---|
| EMI-hardened architecture | 87 dB EMIRR at 1.8 GHz prevents RF-induced offset shifts in proximity to mobile/Wi-Fi antennas - eliminates need for external RF chokes or shielded enclosures. |
| Rail-to-rail output swing | Swings within 7 mV of rails at 10 kΩ load - maximizes dynamic range when driving 12-bit+ SAR ADCs powered from same 3.3 V rail. |
| Ultra-low input bias current | 0.1 pA typical - avoids signal loss and time-constant errors in high-Z piezoelectric or pH electrode interfaces (>1 GΩ source impedance). |
| Wide temperature operation | Specified from −40°C to +125°C - enables direct mounting on motor controllers, HVAC sensors, or automotive cabin modules without derating. |
| Capacitive load drive | Stable with up to 200 pF directly at output - supports direct connection to long PCB traces, unbuffered RC filters, or ADC sample capacitors without isolation resistor. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power, EMI-hardened op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9062IDGKR | Higher GBW (10 MHz), lower noise (7 nV/√Hz), but only 55 dB EMIRR at 1.8 GHz - lacks on-die EMI hardening. | Suitable for low-noise precision apps without strong RF fields; requires external RF filtering in cellular/Wi-Fi proximity. | Select TLV9062IDGKR when noise dominates design budget and RF environment is controlled; avoid where LMV852MMX/NOPB's 87 dB EMIRR is required. |
| OPA2333AIDGKR | Zero-drift architecture (0.02 µV/°C TCVOS), but 0.7 mA per channel supply current and no specified EMIRR - not EMI hardened. | Better for DC-critical applications like strain gauge bridges; higher quiescent current limits battery life in portable use. | Choose OPA2333AIDGKR for microvolt-level DC stability over temperature; LMV852MMX/NOPB preferred for RF-robustness and 0.4 mA efficiency. |
Compared with TLV9062IDGKR and OPA2333AIDGKR, LMV852MMX/NOPB uniquely balances ultra-low power (0.4 mA), industry-leading EMI immunity (87 dB at 1.8 GHz), and rail-to-rail output - making it the only option among the three qualified for battery-powered medical sensors operating in unshielded RF environments.

FAQ
What is the maximum capacitive load LMV852MMX/NOPB can drive without external compensation?
The LMV852MMX/NOPB is unity-gain stable and characterized to drive capacitive loads up to 200 pF directly at its output without oscillation or excessive overshoot. This capability is confirmed in the datasheet Figure 28 (Open Loop Frequency Response vs Load Conditions) and enables direct connection to ADC input capacitors, long PCB traces, or unbuffered RC filters - eliminating the need for series isolation resistors in most sensor interface designs. For loads exceeding 200 pF, an RISO resistor is recommended.
Does LMV852MMX/NOPB support true single-supply operation with input signals extending to ground?
Yes, LMV852MMX/NOPB supports true single-supply operation: its input common-mode voltage range includes ground (−0.2 V minimum at 5 V supply) and extends up to V+ − 1.2 V, while its rail-to-rail output swings within 7 mV of both rails at 10 kΩ load. This allows direct interfacing with grounded sensors (e.g., piezoresistive pressure elements or pH electrodes) and full utilization of 3.3 V or 5 V ADC reference ranges without level-shifting circuitry.
How is EMI rejection quantified for LMV852MMX/NOPB, and what does 87 dB at 1.8 GHz mean in practice?
EMI rejection is quantified as EMIRR (EMI Rejection Ratio), defined as 20·log(VRFpeak/ΔVOS). For LMV852MMX/NOPB, 87 dB at 1.8 GHz means that a 100 mVPK RF signal at that frequency induces less than 1.4 µV of offset voltage shift - verified per test condition VRFpeak = 100 mVP (−20 dBVP). In practice, this enables reliable operation of LMV852MMX/NOPB-based sensor amplifiers within 10 cm of GSM/UMTS cellular antennas without performance degradation.
What is the supply current of LMV852MMX/NOPB at 3.3 V and 25°C, and how does it vary across temperature?
At 3.3 V and 25°C, LMV852MMX/NOPB draws 0.90 mA total (0.45 mA per channel), per the 3.3 V Electrical Characteristics table. Supply current remains stable across temperature: typical values are 0.82 mA at −40°C, 0.90 mA at 25°C, 0.93 mA at 85°C, and 1.06 mA at 125°C - confirming robust low-power operation across the full −40°C to +125°C industrial range without thermal runaway.
Is LMV852MMX/NOPB pin-compatible with other devices in the LMV85x family, such as LMV851 or LMV854?
No, LMV852MMX/NOPB is not pin-compatible with LMV851 (5-pin SC70) or LMV854 (14-pin TSSOP). It uses the 8-pin VSSOP (DGK0008A) package with unique pinout: Pins 1–4 serve Channel A and Power, while Pins 5–8 serve Channel B and Power. Substituting packages requires PCB redesign. However, electrical specifications (GBW, supply current, EMIRR) are tightly aligned across the LMV85x family, enabling consistent system-level performance when migrating between channel counts.
