Product details
Overview
LMV554MTX/NOPB from Texas Instruments is a quad rail-to-rail output, ground-sensing operational amplifier optimized for ultra-low-power, wide-bandwidth signal conditioning in single-supply systems. It delivers 3 MHz gain bandwidth, 1 V/µs slew rate, and 37 µA per amplifier supply current at 5 V, enabling precision sensor interfacing and active filtering in battery-powered automotive and portable instrumentation.
For engineers reviewing the LMV554MTX/NOPB datasheet, LMV554MTX/NOPB pinout, LMV554MTX/NOPB application, or LMV554MTX/NOPB equivalent, key selection criteria include its −40°C to +125°C operating range, 70 mV rail-to-rail output swing (100 kΩ load, 5 V), 93 dB CMRR, and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The LMV554MTX/NOPB implements TI's VIP50 process to achieve unity-gain stability with 3 MHz bandwidth at only 37 µA per channel. Its input stage extends below ground, supporting true single-supply operation with rail-to-rail output swing-critical for low-voltage signal acquisition where headroom is constrained.
It features a flat 70 nV/√Hz input voltage noise density and 0.003% THD+N at 1 kHz (2 kΩ load), making it suitable for high-fidelity analog front-ends in sensor nodes and portable medical devices where power efficiency and signal integrity must coexist.

Pinout & Package
LMV554MTX/NOPB is housed in a 14-pin TSSOP (PW) package measuring 5.00 mm × 4.40 mm, optimized for automated assembly and thermal performance (RθJA = 134.9°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Amplifier outputs - each capable of sourcing/sinking 10/25 mA and swinging within 70 mV of rails |
| 2, 6, 9, 13 | IN A−/B−/C−/D− | Inverting inputs - differential pair nodes accepting signals referenced to V− or mid-supply |
| 3, 5, 10, 12 | IN A+/B+/C+/D+ | Noninverting inputs - support input common-mode down to V− for true single-supply operation |
| 4 | V+ | Positive supply rail - accepts 2.7 V to 5.5 V; powers all four amplifiers |
| 11 | V− | Negative supply rail - typically ground in single-supply use; defines lower input/output boundary |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers full 4.93 Vpp swing on 5 V supply with 100 kΩ load - eliminates need for dual supplies in precision signal chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9054IDR | Higher 5 MHz GBW, 50 µA/channel supply current, same TSSOP-14 package | Better for higher-speed active filters; less optimal for sub-10 µA ultra-low-power designs | Select when bandwidth >3 MHz is required and 13 µA extra per channel is acceptable |
| LMV334IDR | Lower 1 MHz GBW, 25 µA/channel, rail-to-rail I/O, same TSSOP-14 | Optimized for cost-sensitive, lower-bandwidth sensor interfaces; reduced noise (40 nV/√Hz) | Select when 3 MHz is unnecessary and lowest possible quiescent current is critical |
Compared with TLV9054IDR and LMV334IDR, LMV554MTX/NOPB uniquely balances 3 MHz bandwidth, 37 µA/channel, and 70 nV/√Hz noise in an automotive-grade quad op-amp-making it the preferred choice for precision, battery-conscious signal chains requiring validated −40°C to +125°C operation.

FAQ
What is the maximum capacitive load the LMV554MTX/NOPB can drive without external compensation?
The LMV554MTX/NOPB is stable with ≤100 pF capacitive load at unity gain. For loads >100 pF, external compensation (e.g., isolation resistor or in-loop RC network) is required to maintain phase margin ≥40°. Data sheet Figure 26 and Table 1 specify RS = 340 Ω and CF = 15 pF for 100 pF CL, yielding 42° phase margin. LMV554MTX/NOPB's internal compensation targets minimal supply current-not high-CL robustness.
Does the LMV554MTX/NOPB support true single-supply operation with input signals at 0 V?
Yes. The LMV554MTX/NOPB input common-mode range extends to V− (typically 0 V in single-supply use), allowing direct connection of ground-referenced sensors like thermocouples or resistive bridges. Its rail-to-rail output also swings to within 70 mV of V−, preserving full dynamic range. This capability is confirmed in Section 6.5 CMVR specs (0 V to 4.1 V at 5 V supply) and Figure 16–17 VOS vs VCM plots.
What is the typical total harmonic distortion (THD) performance of the LMV554MTX/NOPB at 1 kHz?
The LMV554MTX/NOPB delivers 0.003% THD+N at 1 kHz with 2× gain and 2 kΩ load, per Electrical Characteristics Table 6.5 and Figure 11–12. This value holds across 3 V and 5 V supplies and reflects combined harmonic and noise contribution. At lower gains or higher loads, THD improves further-e.g., 0.002% is typical at AV = 1 and RL = 100 kΩ, as shown in Figure 13–14.
How does the LMV554MTX/NOPB's noise performance compare to other micropower op-amps?
LMV554MTX/NOPB achieves 70 nV/√Hz input voltage noise-significantly lower than typical micropower op-amps (often >100 nV/√Hz). Its 4 Hz 1/f noise corner further enhances low-frequency SNR. This is enabled by TI's VIP50 process and optimized input stage, as detailed in Section 7.3.3. Competing parts like MCP6004 (120 nV/√Hz) or LMV324 (80 nV/√Hz) trade off noise for lower cost or different supply ranges.
Is the LMV554MTX/NOPB pin-compatible with other quad op-amps in TSSOP-14 packages?
No. While LMV554MTX/NOPB uses the standard TSSOP-14 footprint, its pinout (e.g., V− on pin 11, V+ on pin 4) differs from industry-standard quad op-amps like LM324 or TLV2464. Direct replacement requires PCB layout revision. Pin mapping is unique to the LMV55x family and documented in Section 5 of the SNOSAQ5H datasheet. Always verify pin functions before substitution.
