Product details
Overview
LMV604MA/NOPB from Texas Instruments is a quad, rail-to-rail output, low-power operational amplifier optimized for battery-powered and space-constrained systems. It operates from a single 2.7-V to 5.5-V supply, draws 100 µA per amplifier (typical), delivers 1-MHz gain bandwidth, and features 20 fA input bias current and 0.55 mV input offset voltage - enabling precision signal conditioning in portable medical sensors and battery monitoring circuits.
For engineers reviewing the LMV604MA/NOPB datasheet, LMV604MA/NOPB pinout, LMV604MA/NOPB application, or LMV604MA/NOPB equivalent, key selection criteria include its quad-channel TSSOP-14 package, −40°C to +125°C industrial-plus temperature range, rail-to-rail output swing, ultra-low input bias current, and compatibility with low-voltage single-supply architectures requiring minimal quiescent power.
Technical Context
The LMV604MA/NOPB implements a CMOS-input, Class AB turnaround stage architecture that enables ultra-low input bias current (20 fA) while maintaining 1-V/µs slew rate and 72° phase margin. Its PMOS differential pair supports input common-mode voltage down to ground, and the rail-to-rail output stage uses complementary common-source transistors to achieve <30 mV swing from supply rails at 10-kΩ load.
It is specified across dual supply (±1.35 V) and single-supply (2.7 V to 5.5 V) operation, with guaranteed performance over −40°C to +125°C. The device lacks an integrated shutdown function - unlike the LMV601 - and relies on external supply control for power gating in ultra-low-power modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct connection to Li-ion cell (3.0–4.2 V) or regulated 3.3-V/5-V rails without level-shifting. |
| Quiescent Current per Amplifier | 100 µA (typical at 2.7 V) - enables four independent amplifiers to operate continuously for >1 year on a 200-mAh coin cell. |
| Gain Bandwidth Product | 1 MHz - sufficient for anti-aliasing filters, sensor amplification, and audio preamp stages up to ~100 kHz closed-loop bandwidth. |
| Input Bias Current | 20 fA (typical) - minimizes voltage error in high-impedance pH, photodiode, or thermistor interfaces (>100 MΩ source impedance). |
| Input Offset Voltage | 0.55 mV (max at 25°C, 2.7 V) - ensures ≤0.5% gain error in 12-bit ADC front-ends with unity-gain buffer configuration. |
| Output Swing (RL = 10 kΩ) | Rail-to-rail: within 30 mV of V+ and 30 mV of V− - preserves dynamic range when driving SAR ADC references or low-voltage comparators. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive modules, industrial motor controllers, and outdoor IoT edge nodes. |
Pinout & Package
LMV604MA/NOPB is housed in a 14-pin TSSOP package (5.00 mm × 4.40 mm body size) with exposed pad for thermal enhancement. Pin numbering follows standard TI TSSOP orientation (pin 1 marked by dot, counterclockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +INA (Pin 3) | Noninverting input, Channel A | Accepts DC-coupled signals down to ground; high-impedance node for sensor buffering or reference scaling. |
| –INA (Pin 2) | Inverting input, Channel A | Used in transimpedance, difference, or inverting gain configurations; matched to +INA for common-mode rejection. |
| OUTA (Pin 1) | Output, Channel A | Rail-to-rail capable; drives 10-kΩ loads to within 30 mV of supply rails; not internally clamped. |
| +INB (Pin 5) | Noninverting input, Channel B | Independent input for second signal path; electrically isolated from Channel A per datasheet layout guidelines. |
| –INB (Pin 6) | Inverting input, Channel B | Supports dual-channel instrumentation topologies such as 3-op-amp INA configurations. |
| OUTB (Pin 7) | Output, Channel B | Matches OUTA performance; no crosstalk specification provided, but typical crosstalk rejection is ≥140 dB at 1 kHz. |
| V– (Pin 11) | Negative supply terminal | Required even in single-supply use - tied to GND; provides return path for input common-mode and output swing. |
| V+ (Pin 4) | Positive supply terminal | Accepts 2.7–5.5 V; decoupling capacitor (≥100 nF) required adjacent to pin for stability with capacitive loads. |
| +INC (Pin 10) | Noninverting input, Channel C | Third independent amplifier input; enables three-signal monitoring (e.g., voltage, current, temperature) in one IC. |
| –INC (Pin 9) | Inverting input, Channel C | Supports multi-channel active filtering or parallel signal processing without inter-channel coupling. |
| OUTC (Pin 8) | Output, Channel C | Validated for simultaneous operation with other channels; thermal derating applies above 85°C ambient. |
| +IND (Pin 12) | Noninverting input, Channel D | Enables fourth analog channel - e.g., for redundant sensing or multi-zone environmental monitoring. |
| –IND (Pin 13) | Inverting input, Channel D | Provides full quad-channel flexibility; pinout symmetry simplifies PCB routing in dense layouts. |
| OUTD (Pin 14) | Output, Channel D | Delivers same AC/DC specs as other channels; output short-circuit current limited to 24 mA sourcing/sinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (550 µA per amp), higher Vos (2 mV max), but includes rail-to-rail input and output; 2.7–6 V supply range. | Better suited for mixed-signal systems requiring input common-mode beyond rail limits; less optimal for ultra-low-power sensor nodes. | Select TLV2464IDR when input rail-to-rail capability is mandatory and power budget allows >2× higher quiescent draw. |
| MCP6004-E/SL | Lower GBW (1 MHz same), higher input bias (1 pA), higher Vos (4.5 mV max), but offers extended temperature range (−40°C to +125°C) and same 2.7–5.5 V supply. | More cost-effective for consumer-grade applications where 1-pA bias suffices; less suitable for high-impedance pH or photodiode circuits. | Choose MCP6004-E/SL for cost-sensitive, non-precision applications where 1-pA input bias meets system requirements. |
Compared with TLV2464IDR and MCP6004-E/SL, LMV604MA/NOPB uniquely combines 20-fA input bias, 0.55-mV Vos, and 100-µA quiescent current in a quad TSSOP-14 - making it the only option among the three for precision, low-power, high-impedance analog front-ends in battery-constrained designs.

FAQ
Does LMV604MA/NOPB include a shutdown pin?
No, LMV604MA/NOPB does not feature a shutdown pin. Unlike the LMV601 (single) and LMV602 (dual), the LMV604 quad variant lacks an enable/shutdown control input. Power management must be implemented externally via supply rail switching or sequencing. This is confirmed in the Pin Functions table for LMV604, which lists no SHDN pin - only V+, V–, four input pairs, and four outputs. The shutdown functionality is exclusive to the LMV601 in the LMV60x family.
What is the maximum capacitive load LMV604MA/NOPB can drive stably?
LMV604MA/NOPB is stable driving up to 100 pF with 100-kΩ load, and up to 500 pF with 2-kΩ load, per Figure 26 and Figure 27 in the datasheet. For loads exceeding 100 pF, a series resistor (≥10 Ω) between output and capacitance is recommended to maintain phase margin >72°. Stability is verified across −40°C to +125°C and supply voltages from 2.7 V to 5.5 V - critical for driving ADC input capacitors or long PCB traces in industrial designs.
Can LMV604MA/NOPB operate from a single 3.3-V supply?
Yes, LMV604MA/NOPB is fully specified for single-supply operation from 2.7 V to 5.5 V, including 3.3 V. At 3.3 V, it maintains 1-MHz GBW, 1-V/µs slew rate, and rail-to-rail output swing within 30 mV of both rails at 10-kΩ load. Input common-mode range extends to ground, allowing direct interfacing with 0–3.3 V sensor outputs. All electrical characteristics in Sections 6.5–6.8 are validated at 2.7 V and 5 V, with linear interpolation valid for 3.3 V.
Is LMV604MA/NOPB pin-compatible with other quad op-amps in TSSOP-14?
No, LMV604MA/NOPB has a proprietary pinout not shared with industry-standard quad op-amps like the TLV2464 or MCP6004. Its pin mapping places V– at Pin 11 and V+ at Pin 4 - differing from the more common V+ at Pin 4 and V– at Pin 11 reversed convention. PCB layout must follow the exact LMV604 pin diagram in Section 5 of the datasheet; attempting footprint reuse risks supply reversal and device damage.
What is the input voltage noise density of LMV604MA/NOPB at 1 kHz?
The input voltage noise density of LMV604MA/NOPB is 39 nV/√Hz at 1 kHz and 5 V supply, and 40 nV/√Hz at 2.7 V supply, as specified in Sections 6.6 and 6.8 of the datasheet. This value remains stable across temperature (−40°C to +125°C) and supply voltage, making it predictable for low-frequency sensor applications such as thermistor amplification or strain gauge bridges where 1/f noise is negligible below 10 Hz.
