Product details
Overview
TLV2404IN from Texas Instruments is a quad rail-to-rail input/output operational amplifier with 880 nA per channel supply current, reverse battery protection up to 18 V, and operation from 2.5 V to 16 V. It features ±200 µA output drive, 5.5 kHz gain bandwidth, and 390 µV typical input offset voltage at 25°C - enabling ultra-low-power sensor signal conditioning in battery-powered industrial monitoring systems.
For engineers reviewing the TLV2404IN datasheet, TLV2404IN pinout, TLV2404IN application, or TLV2404IN equivalent, key selection criteria include its sub-1-µA quiescent current per channel, 5-V over-the-rail input capability, –40°C to 125°C industrial temperature rating, and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2404IN employs a hybrid PNP/NPN input stage enabling rail-to-rail common-mode input range (–0.1 V to VCC + 5 V) and stable operation under reverse-battery conditions. Its internal Schottky diode network limits reverse supply current to 50 nA at –18 V, while maintaining functional integrity without external protection circuitry.
DC precision is supported by 120 dB CMRR, 130 V/mV open-loop gain at 2.7 V, and low input bias current (100 pA typ. at 25°C), making it suitable for high-impedance transducer interfaces where leakage-induced errors must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current / Ch | 880 nA typ. - enables multi-year battery life in always-on IoT sensors |
| Gain Bandwidth Product | 5.5 kHz - sufficient for DC-coupled thermistor, RTD, or pH electrode signal conditioning |
| Input Offset Voltage | 390 µV typ. at 25°C - supports <1 mV total error budget in 12-bit ADC front-ends |
| Common-Mode Range | –0.1 V to VCC + 5 V - allows direct interface to overvoltage-tolerant sensors or mismatched supply domains |
| Reverse Battery Protection | Up to –18 V - eliminates need for external series diode or MOSFET in 12-V automotive/industrial battery systems |
| Operating Temperature | –40°C to 125°C - qualified for under-hood, motor control, and factory-floor embedded applications |
| Output Drive | ±200 µA - sufficient to drive 100-kΩ load with rail-to-rail swing at 2.7 V supply |
Pinout & Package
The TLV2404IN is housed in a 14-pin TSSOP (PW) package with exposed pad, measuring 5.0 mm × 4.4 mm × 1.2 mm. Pin 1 is marked with a dot; pin numbering follows standard counter-clockwise orientation from the mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OUT) | Channel 1 output | Rail-to-rail sourcing/sinking up to ±200 µA; connects directly to ADC input or filter network |
| 2 (1IN–) | Channel 1 inverting input | High-impedance node (300 MΩ differential); sensitive to layout-induced noise - keep trace short |
| 3 (1IN+) | Channel 1 noninverting input | Accepts signals from –0.1 V to VCC + 5 V; enables single-supply sensor biasing above VCC |
| 4 (VCC) | Positive supply | 2.5 V to 16 V operation; requires local 0.1-µF ceramic + 6.8-µF tantalum decoupling |
| 5 (2IN+) | Channel 2 noninverting input | Independent high-Z input; shares VCC and GND with other channels |
| 6 (2IN–) | Channel 2 inverting input | Matched to Pin 2; supports dual-channel differential sensing |
| 7 (2OUT) | Channel 2 output | Identical performance to Pin 1; usable for feedback or independent signal path |
| 8 (GND) | Analog ground reference | Must connect to low-impedance ground plane; separate from digital ground if mixed-signal |
| 9 (3OUT) | Channel 3 output | Third independent output; enables 3-channel sensor monitoring or multi-stage filtering |
| 10 (3IN–) | Channel 3 inverting input | Same electrical characteristics as Pins 2 and 6; layout symmetry recommended |
| 11 (3IN+) | Channel 3 noninverting input | Supports same over-rail operation; used for third sensor or reference buffer |
| 12 (VCC) | Positive supply (redundant) | Second VCC pin improves power delivery integrity; tie directly to main VCC plane |
| 13 (4IN+) | Channel 4 noninverting input | Enables full quad-channel configuration; e.g., three sensors + one reference buffer |
| 14 (4IN–) | Channel 4 inverting input | Final high-Z input; matches all other inputs in bias current and CMR |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404ID | Same electrical specs but in SOIC-14 package (5.0 mm × 6.2 mm); higher θJA (122.6°C/W) vs. TSSOP-14 (173.6°C/W) | Larger footprint; less suitable for dense portable designs; better manual solderability | Select TLV2404ID only when SOIC hand-soldering or legacy board compatibility is required |

FAQ
What is the maximum supply voltage for TLV2404IN, and what happens if exceeded?
The absolute maximum supply voltage for TLV2404IN is 17 V. Operation above 16 V violates recommended conditions and may cause permanent damage. At 16 V, the device delivers full rail-to-rail output swing and specified 5.5 kHz bandwidth; exceeding this risks junction overheating and parametric shift, especially at elevated ambient temperatures.
Does TLV2404IN support true rail-to-rail input when VCC = 2.5 V?
Yes. TLV2404IN guarantees rail-to-rail input operation from –0.1 V to VCC + 5 V across its full supply range. At VCC = 2.5 V, the input common-mode range extends from –0.1 V to +7.5 V, enabling direct interface to sensors biased above the supply - critical for accurate low-voltage system calibration.
Can TLV2404IN drive a 10-nF capacitive load stably?
No. TLV2404IN is optimized for loads ≤100 pF. Driving 10 nF directly causes severe phase margin degradation (<10°), leading to oscillation. For larger capacitive loads, add a series isolation resistor (≥1 kΩ) between TLV2404IN output and the capacitor, or use a unity-gain buffer stage with higher drive capability.
How does reverse battery protection work in TLV2404IN?
TLV2404IN integrates six internal Schottky diodes that clamp reverse current to <100 nA at –18 V and 25°C. This architecture prevents destructive latch-up or junction breakdown during accidental battery reversal - eliminating need for external protection diodes while maintaining functional integrity of all four amplifier channels.
Is TLV2404IN pin-compatible with other quad op-amps in TSSOP-14?
No. TLV2404IN uses a non-standard pinout optimized for quad-channel independence and low crosstalk: pins 1–3 and 9–11 serve as outputs/inputs for channels 1–4 respectively, with dual VCC (Pins 4 and 12) and single GND (Pin 8). It is not pin-compatible with generic TSSOP-14 op-amps like LM324 or MCP6004.
