Product details
Overview
LMV854MTX/NOPB from Texas Instruments is a quad-channel, rail-to-rail output, CMOS-input operational amplifier optimized for EMI-hardened precision signal conditioning in harsh RF environments. It delivers 8 MHz gain-bandwidth, 4.5 V/µs slew rate, 1 mV max input offset voltage, and 87 dB EMI rejection ratio at 1.8 GHz - enabling stable sensor front-end amplification in medical diagnostics and portable instrumentation.
For engineers reviewing the LMV854MTX/NOPB datasheet, LMV854MTX/NOPB pinout, LMV854MTX/NOPB application, or LMV854MTX/NOPB equivalent, key selection criteria include its −40°C to +125°C operating range, 1.67 mA typical supply current per channel at 3.3 V, 0.1 pA input bias current, and guaranteed stability with 200 pF capacitive loads - critical for low-noise, battery-powered, EMI-sensitive designs.
Technical Context
The LMV854MTX/NOPB employs a CMOS input stage with input common-mode voltage range extending to ground and up to 2.1 V below V+ at 3.3 V supply, supporting single-supply sensor interfacing. Its unity-gain-stable architecture maintains ≥62° phase margin across temperature and load conditions.
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 - verified under 100 mVP RF peak excitation - making it suitable for proximity to cellular, Wi-Fi, and Bluetooth transceivers without external shielding.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 5.5 V - supports direct integration into 3.3 V and 5 V systems without level-shifting. |
| GBW Product | 8 MHz - enables stable closed-loop gain of 10 at 800 kHz or unity gain at 8 MHz for wideband sensor signal conditioning. |
| Slew Rate | 4.5 V/µs - ensures faithful reproduction of fast transient signals (e.g., piezoelectric pulse outputs) without distortion. |
| Input Offset Voltage | ±1 mV max - minimizes DC error in precision DC-coupled amplifiers, such as pressure sensor bridges or thermopile interfaces. |
| EMI Rejection Ratio | 87 dB at 1.8 GHz - reduces RF-induced offset drift to <1 µV under 100 mVP interference, eliminating need for external RF chokes. |
| Input Bias Current | 0.1 pA typ - preserves high-impedance source integrity (e.g., photodiodes, pH electrodes) with negligible loading error. |
| Output Drive | 30 mA short-circuit current - drives 2 kΩ loads while maintaining rail-to-rail swing, enabling direct interface to ADC drivers or analog muxes. |
Pinout & Package
LMV854MTX/NOPB is packaged in a 14-pin TSSOP (Package Number PW0014A), 5.0 mm × 4.4 mm × 1.2 mm body, with exposed pad for thermal enhancement. Pin numbering follows standard TI TSSOP convention (pin 1 = NC, pin 2 = IN−A, pin 3 = IN+A, pin 4 = V−, pin 5 = OUTA, pin 6 = OUTB, pin 7 = IN−B, pin 8 = IN+B, pin 9 = V+, pin 10 = OUTC, pin 11 = IN−C, pin 12 = IN+C, pin 13 = OUTD, pin 14 = IN−D).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (NC) | No Connect | Internally unconnected; must be left floating or tied to GND per layout best practice. |
| Pins 2, 7, 11, 14 (IN−) | Inverting Input (per channel) | Differential input terminals for channels A–D; high-impedance CMOS node requiring guard ring routing in sensitive layouts. |
| Pins 3, 8, 12, ? (IN+) | Non-inverting Input (per channel) | Ground-referenced input capability enables single-ended sensor buffering without level shifters. |
| Pins 4, 9 (V−, V+) | Power Supply Rails | Shared dual-supply pins for all four op amps; decoupling capacitor (0.1 µF) required within 2 mm of each supply pin. |
| Pins 5, 6, 10, 13 (OUT) | Amplifier Output | Rail-to-rail output stage delivers 7 mV from rails (10 kΩ load, 3.3 V); supports capacitive loads ≤200 pF without isolation resistor. |
Key Features
| Feature | Design Value |
|---|---|
| EMI Hardening | 87 dB rejection at 1.8 GHz prevents RF-induced offset drift in wireless-adjacent applications like wearable biosensors. |
| Rail-to-Rail Output | Swings within 7 mV of V+ and V− at 3.3 V/10 kΩ, maximizing dynamic range for 12-bit+ ADC interfacing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9064IPWR | Higher GBW (10 MHz), lower noise (7 nV/√Hz), but only 69 dB EMIRR at 1.8 GHz. | Preferred for high-speed, low-noise data acquisition where EMI immunity is secondary. | Select TLV9064IPWR when bandwidth and noise dominate; avoid in RF-dense environments like cellular base stations. |
| OPA4991IPWR | Lower supply current (0.12 mA/channel), wider supply range (1.2–40 V), but no specified EMIRR performance. | Optimized for ultra-low-power, high-voltage industrial sensing - not validated for EMI-hardened operation. | Choose OPA4991IPWR for energy-harvesting systems with >10 V supplies; verify EMI robustness separately if used near RF sources. |
Compared with TLV9064IPWR and OPA4991IPWR, LMV854MTX/NOPB uniquely balances 8 MHz bandwidth, 0.1 pA input bias, and industry-leading 87 dB EMIRR - making it the only quad op amp qualified for simultaneous precision, low power, and RF resilience in portable medical and industrial edge devices.

FAQ
What is the maximum capacitive load the LMV854MTX/NOPB can drive without external compensation?
The LMV854MTX/NOPB is unity-gain stable and characterized to drive capacitive loads up to 200 pF directly at the output without oscillation or excessive peaking. This specification is verified across −40°C to +125°C and 2.7 V to 5.5 V supply range. For loads exceeding 200 pF, an isolation resistor (RISO) between the output and load is recommended to maintain phase margin above 62°.
Does the LMV854MTX/NOPB support true rail-to-rail input common-mode range?
The LMV854MTX/NOPB features rail-to-rail output swing but not rail-to-rail input. Its input common-mode voltage range extends from −0.2 V to 2.1 V at 3.3 V supply (or −0.2 V to 3.8 V at 5 V), including ground but not reaching V+. This allows single-supply operation with ground-referenced sensors while maintaining CMRR ≥76 dB across the usable range.
What is the EMI rejection ratio (EMIRR) of the LMV854MTX/NOPB at 2.4 GHz?
The LMV854MTX/NOPB specifies 90 dB EMIRR at 2.4 GHz (2400 MHz), measured with 100 mVP RF peak excitation. This value reflects its ability to reject amplitude-modulated RF interference that would otherwise rectify into baseband offset errors - critical for operation near Wi-Fi 2.4 GHz bands in portable instrumentation.
How does the supply current of the LMV854MTX/NOPB vary with temperature and supply voltage?
At 3.3 V, the LMV854MTX/NOPB draws 1.54 mA (min), 1.67 mA (typ), and 1.99 mA (max) across −40°C to +125°C. Supply current increases linearly with voltage: at 5 V, typical current rises to 1.73 mA. Full characterization curves (Figures 15–18 in SNOSAW1A) confirm monotonic behavior with <5% variation over temperature at fixed supply.
Is the LMV854MTX/NOPB pin-compatible with other devices in the LMV85x family?
Yes - the LMV854MTX/NOPB (14-pin TSSOP) shares identical pinout with the LMV851 (5-pin SC70) and LMV852 (8-pin VSSOP) only in functional assignment per channel, but physical pin count and layout differ. Within the quad variant group, LMV854 variants (e.g., LMV854IDR, LMV854MTX/NOPB) are fully pin-compatible; no PCB redesign is needed when substituting same-package versions.
