Product details
Overview
LMV604MTX/NOPB from Texas Instruments is a quad, rail-to-rail output, low-power operational amplifier optimized for 2.7-V to 5.5-V single-supply operation. It delivers 1-MHz gain bandwidth, 1-V/µs slew rate, 100-µA per amplifier supply current, and 20-fA input bias current, enabling precision signal conditioning in space-constrained battery-powered systems such as portable medical sensors and handheld test equipment.
For engineers reviewing the LMV604MTX/NOPB datasheet, LMV604MTX/NOPB pinout, LMV604MTX/NOPB application, or LMV604MTX/NOPB equivalent, key selection criteria include its rail-to-rail output swing (within 30 mV of rails at 2.7 V), ultra-low input bias current for high-impedance sensor interfacing, −40°C to +125°C industrial-plus temperature range, and TSSOP-14 package compatibility with automated PCB assembly.
Technical Context
The LMV604MTX/NOPB uses a PMOS input stage to achieve 20-fA typical input bias current and rail-to-rail output via complementary common-source transistors. Its patented Class AB turnaround stage reduces quiescent current without compromising slew rate, yielding low offset (0.55 mV typ), low noise (39 nV/√Hz at 1 kHz), and high open-loop gain.
It operates across 2.7 V to 5.5 V with guaranteed specifications at both 2.7 V and 5 V, supports input common-mode voltage down to ground, and maintains stability with capacitive loads up to 1000 pF. No shutdown pin is present-unlike the LMV601-making it a dedicated quad amplifier without power-gating capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (550 µA per amp), 6.4-MHz GBW, no guaranteed 2.7-V operation | Better for higher-speed active filters but unsuitable for sub-100-µA battery life targets | Select TLV2464IDR only when bandwidth >2 MHz is required and power budget allows ≥2.2-mA total IQ |
| MCP6004-E/SL | Lower IQ (1 µA), 1-MHz GBW, but 7-mV max VOS and 1.2-pA IB - 60× higher input bias than LMV604MTX/NOPB | Acceptable for general-purpose IO buffering but not for picoampere-level sensor nodes | Choose MCP6004-E/SL for cost-sensitive non-precision applications where input impedance >100 MΩ suffices |
Compared with TLV2464IDR and MCP6004-E/SL, LMV604MTX/NOPB uniquely balances ultra-low input bias current (20 fA), rail-to-rail output, and 100-µA quiescent current-making it the only option among the three qualified for high-impedance, low-power, wide-temperature sensor front-ends.

FAQ
What is the maximum capacitive load the LMV604MTX/NOPB can drive stably?
The LMV604MTX/NOPB is characterized for stable operation with capacitive loads up to 1000 pF when configured as a unity-gain buffer, per TI's Figure 25 and Figure 26. This eliminates the need for series isolation resistors in LCD bias, capacitive touch, or DAC output buffering applications-reducing component count and board area. For loads exceeding 1000 pF, external compensation or a follower-with-isolation-resistor topology is recommended. LMV604MTX/NOPB's internal compensation ensures phase margin remains ≥72° under these conditions.
Does the LMV604MTX/NOPB have a shutdown pin?
No, the LMV604MTX/NOPB does not include a shutdown pin. Unlike the LMV601 (single) and LMV602 (dual), the quad LMV604 variant is designed as a fixed-function amplifier without power-gating capability. All four amplifiers operate continuously when powered. If system-level power cycling is required, external FET switching of the V+ supply or use of the LMV601/LMV602 variants with SHDN pins is necessary. LMV604MTX/NOPB's 100-µA per amplifier supply current is optimized for always-on low-power operation instead.
What is the input common-mode voltage range for the LMV604MTX/NOPB at 2.7-V supply?
At 2.7-V supply, the LMV604MTX/NOPB supports an input common-mode voltage range from 0 V (ground) to 1.7 V, as specified in Section 6.5 of the datasheet. This rail-to-ground input capability enables direct interfacing with sensors referenced to system ground-such as thermistors, RTDs, or bridge transducers-without level-shifting circuitry. The device maintains ≥50-dB CMRR across this range, ensuring accurate differential measurements even with mismatched source impedances. LMV604MTX/NOPB's PMOS input stage enables this extended low-side range.
Can the LMV604MTX/NOPB be used with a single 3.3-V supply?
Yes, the LMV604MTX/NOPB is fully specified and guaranteed for operation at 3.3 V, falling within its 2.7-V to 5.5-V supply range. At 3.3 V, it delivers 1-MHz GBW, 1-V/µs slew rate, and rail-to-rail output swing within 25 mV of V+ and V−. Input offset voltage remains ≤5 mV (max), and supply current is 107–200 µA per amplifier (typ/max). This makes LMV604MTX/NOPB ideal for 3.3-V microcontroller-based systems requiring precision analog front-ends without additional voltage regulation.
How does the LMV604MTX/NOPB's input bias current compare to bipolar-input op-amps?
The LMV604MTX/NOPB's PMOS input stage achieves 20 fA typical input bias current-over six orders of magnitude lower than typical bipolar-input op-amps (e.g., 100 nA for LM358). This enables accurate measurement of ultra-high-impedance sources like pH electrodes (>1 GΩ), photodiodes in photovoltaic mode, or piezoelectric sensors without significant signal attenuation or DC error. At 25°C and VCM = 1.35 V, input bias current remains stable below 100 fA across the full operating temperature range. LMV604MTX/NOPB's fA-level bias is critical for maintaining accuracy in multi-decade resistance measurement circuits.
