Product details
Overview
LMV852MME/NOPB from Texas Instruments is a dual-channel, rail-to-rail output, CMOS-input operational amplifier optimized for EMI-sensitive signal conditioning in industrial and medical sensor interfaces. 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 robust operation near RF sources such as cellular transceivers or wireless peripherals.
For engineers reviewing the LMV852MME/NOPB datasheet, LMV852MME/NOPB pinout, LMV852MME/NOPB application, or LMV852MME/NOPB equivalent, this page provides verified specifications, package-confirmed pin functions, real-world use cases in piezoelectric and photodiode amplification, and validated alternative parts with documented functional trade-offs.
Technical Context
The LMV852MME/NOPB implements a unity-gain-stable CMOS input stage with input common-mode voltage range extending to ground and beyond (−0.2 V), supporting single-supply sensor front-ends. Its EMI hardening architecture suppresses RF-induced offset voltage shifts via on-die filtering and layout techniques validated up to 2.4 GHz.
It maintains stability driving capacitive loads up to 200 pF without external compensation and achieves 92 dB CMRR and 93 dB PSRR across 2.7–5.5 V supply range - critical for precision DC-coupled amplification in battery-powered portable equipment.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9062IDGKR | Higher GBW (10 MHz), lower input noise (7 nV/√Hz), but only 79 dB EMIRR at 1.8 GHz. | Preferred for wideband photodiode preamps where noise dominates; less suitable for RF-dense medical enclosures. | Select when bandwidth/noise outweigh EMI immunity; verify layout shielding if used near 2.4 GHz transmitters. |
| OPA2333AIDGKR | Zero-drift architecture, 2 µV max VOS, but 0.8 mA per channel supply current and no published EMIRR spec. | Better for DC-precision applications like strain gauge bridges; unsuitable for unshielded RF environments. | Choose for sub-µV offset-critical designs; avoid where RF exposure exceeds 400 MHz without additional filtering. |
Compared with TLV9062IDGKR and OPA2333AIDGKR, the LMV852MME/NOPB uniquely balances EMI resilience (87 dB at 1.8 GHz), ultra-low quiescent current (0.4 mA/channel), and rail-to-rail output - making it optimal for compact, battery-operated sensor nodes deployed in mixed-signal RF environments without added shielding.

FAQ
What is the maximum capacitive load the LMV852MME/NOPB can drive without oscillation?
The LMV852MME/NOPB is specified to remain stable with capacitive loads up to 200 pF when configured as a unity-gain buffer. This capability eliminates the need for external isolation resistors in many sensor interface and ADC driver applications. For loads exceeding 200 pF, a series isolation resistor (RISO) between the output and the load is recommended to maintain phase margin above 60°, as confirmed in TI's SNOSAW1A datasheet Figure 28 and Application Note SLOA099.
Does the LMV852MME/NOPB support true rail-to-rail input common-mode range?
The LMV852MME/NOPB features a rail-to-rail *output*, but its input common-mode voltage range extends from −0.2 V to (V+ − 1.2 V) - meaning it includes ground and operates down to −0.2 V, but does not reach the positive rail. At 3.3 V supply, the usable input range is −0.2 V to 2.1 V; at 5 V, it is −0.2 V to 3.8 V. This design enables ground-referenced sensor inputs while maintaining 92 dB CMRR across the supported range.
What is the measured EMI Rejection Ratio (EMIRR) of the LMV852MME/NOPB at 900 MHz?
The LMV852MME/NOPB delivers a minimum EMIRR of 78 dB at 900 MHz, as tested per TI's SNOSAW1A datasheet (Table 1, 3.3 V Electrical Characteristics). This value reflects the device's ability to suppress RF-induced input offset voltage shifts under 100 mVP (−20 dBVP) interference - a key differentiator for operation near GSM/EDGE base stations or mobile handsets.
Can the LMV852MME/NOPB operate from a single 2.7 V supply?
Yes, the LMV852MME/NOPB is fully specified for operation from 2.7 V to 5.5 V single-supply configurations. At 2.7 V, it maintains 8 MHz GBW, 4.5 V/µs slew rate, and rail-to-rail output swing - enabling compatibility with energy-harvesting systems and low-voltage battery packs. Supply current remains below 0.6 mA per channel across this range, as shown in Figure 13 of the SNOSAW1A datasheet.
Is the LMV852MME/NOPB pin-compatible with other members of the LMV85x family?
No - the LMV852MME/NOPB (8-pin VSSOP) is not pin-compatible with the LMV851 (5-pin SC70) or LMV854 (14-pin TSSOP). Each variant uses a distinct pinout optimized for channel count and package constraints. The LMV852MME/NOPB's 8-pin DGK package places both inputs and outputs for each channel on opposite sides of the IC to minimize crosstalk, as detailed in Figure 3 of SNOSAW1A.
