Product details
Overview
LMV604MAX/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 2.7 V to 5.5 V, draws 100 µA per amplifier (typ), delivers 1 MHz gain bandwidth, 1 V/µs slew rate, and features 20 fA input bias current - enabling precision sensing and signal conditioning in portable electronics.
For engineers reviewing the LMV604MAX/NOPB datasheet, LMV604MAX/NOPB pinout, LMV604MAX/NOPB application, or LMV604MAX/NOPB equivalent, key selection criteria include its quad-channel configuration, TSSOP-14 package footprint, shutdown capability (on LMV601 only), rail-to-rail output swing, and ultra-low input bias current for high-impedance sensor interfaces.
Technical Context
The LMV604MAX/NOPB implements a CMOS-input, Class AB folded cascode architecture that achieves ultra-low input bias current (20 fA) while maintaining 1 MHz GBW and 1 V/µs slew rate. Its PMOS differential pair enables input common-mode range extending to ground, and the rail-to-rail output stage supports full-swing operation down to 30 mV from supply rails at 10 kΩ load.
It is specified across −40°C to +125°C with guaranteed performance at both 2.7 V and 5 V supplies. Input offset voltage is 0.7 mV (max at 5 V), CMRR is 86 dB, PSRR is 82 dB, and input-referred voltage noise is 39 nV/√Hz at 1 kHz - making it suitable for DC-coupled, low-noise, low-power analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion, 3.3 V, and 5 V systems without level-shifting. |
| Quiescent Current (per amp) | 100 µA (typ) - enables multi-channel amplification in always-on battery monitoring circuits. |
| Gain Bandwidth Product | 1 MHz - sufficient for anti-aliasing filters, sensor buffers, and audio preamps up to ~100 kHz. |
| Slew Rate | 1 V/µs - ensures faithful reproduction of 100-kHz, 1-VPP signals with <1% distortion. |
| Input Bias Current | 20 fA (typ) - minimizes voltage error in photodiode, pH electrode, and high-Z resistive sensor interfaces. |
| Input Offset Voltage | 0.7 mV (max at 5 V) - enables accurate DC-coupled gain stages with ≤0.07% error at unity gain. |
| Rail-to-Rail Output | Swings within 30 mV of V+ and V− - maximizes dynamic range in low-voltage ADC driver applications. |
Pinout & Package
LMV604MAX/NOPB is housed in a 14-pin TSSOP package (5.00 mm × 4.40 mm), optimized for compact PCB layouts in portable equipment. Pin functions are validated per TI SNOSC70C datasheet Rev C.
| Pin/Terminal | Circuit Role | Design Meaning |

| 3 (+INA) | Noninverting Input, Channel A | Differential input node for channel A; compatible with ground-referenced sensors. |
| 4 (V+) | Positive Supply | Main power rail; must be decoupled with ≥0.1 µF ceramic capacitor near pin. |

| 11 (V–) | Negative Supply | Ground reference or negative rail; required for dual-supply operation (e.g., ±2.5 V). |
| 12 (+IND) | Noninverting Input, Channel D | Fourth input; enables four independent signal paths on one IC - reducing board area by 75% vs discrete solutions. |
| 13 (–IND) | Inverting Input, Channel D | Fourth differential input; fully isolated; supports individual gain and filter configurations. |
| 14 (OUTD) | Output, Channel D | Final output; matches all electrical specs of other channels; no shared internal nodes. |

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/amp), higher input offset (2 mV max), no guaranteed 2.7 V operation. | Better drive strength (35 mA short-circuit), but unsuitable for ultra-low-power sensor nodes. | Choose TLV2464IDR when driving heavy capacitive loads or requiring higher output current; avoid for sub-500 µA system budgets. |
| MCP6004-E/ST | Lower GBW (1 MHz same), higher input bias (1 pA), wider VOS range (1.5 mV max), smaller TSSOP-14 footprint (4.4 × 5.0 mm vs 5.0 × 4.4 mm). | Optimized for cost-sensitive consumer electronics; lacks guaranteed 125°C operation. | Choose MCP6004-E/ST for commercial-grade portable devices where extended temperature range is not required. |
Compared with TLV2464IDR and MCP6004-E/ST, LMV604MAX/NOPB uniquely combines 20 fA input bias, −40°C to +125°C operation, and 100 µA/amp quiescent current - making it the only option for precision, wide-temperature, ultra-low-power quad amplification in industrial and automotive edge sensors.

FAQ
What is the maximum operating temperature for LMV604MAX/NOPB?
The LMV604MAX/NOPB is fully specified from −40°C to +125°C ambient temperature. This industrial-plus grade rating is confirmed in Section 6.3 (Recommended Operating Conditions) of the TI SNOSC70C datasheet and validated across all electrical parameters including input offset, CMRR, and supply current - making LMV604MAX/NOPB suitable for under-hood automotive and industrial motor control environments.
Does LMV604MAX/NOPB include a shutdown pin?
No, LMV604MAX/NOPB does not include a shutdown pin. Shutdown functionality is exclusive to the LMV601 single-channel variant (pin 5). The LMV604MAX/NOPB is a quad amplifier with fixed operation - all four channels remain active whenever V+ and V− are powered. This simplifies design for always-on applications like continuous sensor monitoring.
What is the input common-mode voltage range of LMV604MAX/NOPB?
At 5 V supply, the input common-mode voltage range of LMV604MAX/NOPB is 0 V to 4 V (Section 6.5, VCM specification). At 2.7 V supply, it is 0 V to 1.7 V. This ground-sensing capability stems from its PMOS input stage and enables direct interfacing with 0 V–referenced sensors such as thermistors, RTDs, and bridge transducers without level-shifting circuitry.
Can LMV604MAX/NOPB drive capacitive loads?
Yes, LMV604MAX/NOPB is stable with capacitive loads up to 1000 pF, as verified in Figure 24–27 of the TI SNOSC70C datasheet. For loads >100 pF, a small series resistor (10–50 Ω) between amplifier output and load is recommended to maintain phase margin above 72° and prevent peaking. Stability is confirmed across temperature and supply voltage variations.
Is LMV604MAX/NOPB RoHS-compliant and lead-free?
Yes, LMV604MAX/NOPB is RoHS-compliant and lead-free. The "/NOPB" suffix explicitly denotes "No Lead (Pb)-Free" packaging per TI's part numbering convention. It meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) and is qualified for Pb-free reflow soldering profiles up to 260°C peak temperature.
