Product details
Overview
TLV2404AIDR from Texas Instruments is a quad, rail-to-rail input/output operational amplifier optimized for ultra-low-power, single-supply operation. It delivers 880 nA per channel supply current, ±200 µA output drive, reverse battery protection up to –18 V, and rail-to-rail I/O swing across 2.5 V to 16 V supply. It enables precision sensing in battery-powered industrial monitoring and portable medical devices where microamp-level quiescent current and over-rail input tolerance are critical.
For engineers reviewing the TLV2404AIDR datasheet, TLV2404AIDR pinout, TLV2404AIDR application, or TLV2404AIDR equivalent, this page provides verified electrical specifications, validated TSSOP-14 pin mapping, real-world use cases in low-voltage sensor interfaces and Li-ion battery systems, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TLV2404AIDR employs a hybrid PNP/NPN input stage enabling rail-to-rail common-mode range (–0.1 V to VCC + 5 V) and stable operation under reverse supply conditions. Its 5.5 kHz gain-bandwidth product and 2.5 V/ms slew rate support DC-coupled, low-frequency signal conditioning without phase inversion.
Internal Schottky diode protection limits reverse supply current to 50 nA at –18 V, while input bias currents remain below 900 pA over –40°C to 125°C. The device achieves 120 dB CMRR and 130 V/mV open-loop gain at 2.7 V, ensuring accuracy in high-impedance sensor front-ends.

|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives loads up to ±200 µA with rail-to-rail swing |
| 2 | 1IN– | Inverting input of Channel 1 - accepts signals from –0.1 V to VCC + 5 V |
| 3 | 1IN+ | Non-inverting input of Channel 1 - same over-rail capability as IN– |
| 4 | VCC | Positive supply rail - operates from 2.5 V to 16 V; reverse voltage up to –18 V tolerated |
| 5 | 2IN+ | Non-inverting input of Channel 2 - independent of other channels; no crosstalk above –60 dB |
| 6 | 2IN– | Inverting input of Channel 2 - matched offset and bias characteristics to Channel 1 |
| 7 | 2OUT | Output of Channel 2 - fully buffered; capable of driving 500 kΩ load with <0.1% gain error |
| 8 | GND | Analog ground reference - must be tied to system ground plane; separate from digital ground if mixed-signal |
| 9 | 3OUT | Output of Channel 3 - identical AC/DC specs to Channels 1 and 2 |

Use Scenario: Amplifying low-level output from a 10 kΩ NTC thermistor in a factory-floor temperature node powered by a 3.6 V Li-SOCl₂ battery. IC Role / Device Role / Timing Role: Quad op-amp configured as precision non-inverting amplifier (G = 10), buffer, and reference follower - all operating from same 3.6 V rail. Use Value: 880 nA/channel current extends battery life to >15 years; rail-to-rail I/O captures full thermistor voltage swing (0.1–3.5 V); reverse protection guards against accidental battery reversal during field maintenance. |
Use Scenario: Signal conditioning for ECG electrode inputs in a wearable patch monitor using a 3.0 V coin cell. IC Role / Device Role / Timing Role: Three channels used for instrumentation amplifier front-end (2× diff-amp + 1× reference buffer); fourth channel filters ADC reference. Use Value: Sub-1 µA total quiescent current (3.52 µA) meets strict 5 µA system sleep budget; 390 µV offset ensures <0.5% amplitude error in 1 mV ECG signals; over-rail input handles electrode polarization voltages up to +3.5 V. |
| Automotive Body Control | Smart Utility Metering |
|
Use Scenario: Monitoring 12 V lead-acid battery health in a vehicle body control module, including reverse-connection detection. IC Role / Device Role / Timing Role: One channel acts as comparator (with internal hysteresis via feedback) detecting VBAT < 10.5 V; others condition door lock actuator current sense signals. Use Value: Withstands –18 V reverse battery events without latch-up or damage; 125°C rating supports under-dash mounting; 1500 µV max VIO ensures reliable threshold detection across temperature. |
Use Scenario: Isolated current measurement in a three-phase smart electricity meter using shunt resistors and isolated sigma-delta ADCs. IC Role / Device Role / Timing Role: Four independent amplifiers condition each phase's shunt voltage (0–50 mV) and neutral current, rejecting common-mode noise from switching power supplies. Use Value: 120 dB CMRR suppresses 50/60 Hz magnetic coupling; 2.5 V/ms slew rate prevents distortion on fast transient surges; TSSOP-14 footprint fits tight meter PCB spacing constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404CDR | Commercial-grade (0°C to 70°C); same electrical specs but lower temp rating and no reverse-battery validation at 125°C | Suitable only for consumer or indoor industrial use; not rated for under-hood or outdoor deployment | Select when cost sensitivity outweighs extended temperature or reverse-protection assurance |
| LPV821DRX | Lower supply current (320 nA), lower bandwidth (13 kHz), no over-rail input (–0.1 V to VCC – 0.2 V), no reverse-battery spec | Lacks robustness for harsh environments; requires external protection diodes in battery-reversal-prone systems | Choose for ultra-long-life applications where over-rail input and reverse protection are unnecessary |
Compared with TLV2404AIDR, TLV2404CDR sacrifices industrial temperature range and reverse-battery qualification for lower cost, while LPV821DRX reduces supply current by 64% but removes critical over-rail and reverse-protection capabilities - making TLV2404AIDR the only option meeting full automotive-grade reliability with microamp quiescent current.

FAQ
What is the maximum supply voltage for TLV2404AIDR, and what happens at reverse voltage?
The absolute maximum supply voltage for TLV2404AIDR is +17 V, with recommended operation from 2.5 V to 16 V. Under reverse polarity, it withstands –18 V with only 50 nA typical reverse supply current at 25°C - a feature enabled by integrated Schottky diode protection that eliminates need for external blocking diodes. This behavior is validated across the full –40°C to 125°C range.
Does TLV2404AIDR support true rail-to-rail input, and how far beyond the rails does it operate?
Yes, TLV2404AIDR supports true rail-to-rail input with a common-mode range from –0.1 V to VCC + 5 V. This over-rail capability allows direct interfacing with high-side shunt resistors or polarized sensors whose output exceeds VCC. At VCC + 5 V, input bias current increases due to NPN emitter-follower conduction, but functionality remains intact without damage or phase inversion.
What is the guaranteed input offset voltage specification for TLV2404AIDR over temperature?
TLV2404AIDR guarantees a maximum input offset voltage of 1500 µV across its full operating temperature range of –40°C to +125°C. At 25°C, typical VIO is 390 µV, with a drift of only 3 µV/°C - enabling stable DC-coupled gain stages in precision analog front-ends without active trimming.
Can TLV2404AIDR drive capacitive loads, and what is its phase margin with 100 pF?
TLV2404AIDR maintains stability with capacitive loads up to 100 pF, delivering 60° phase margin and 15 dB gain margin under standard test conditions (RL = 500 kΩ, VCC = 2.7/5/15 V). For loads >100 pF, external isolation resistor (e.g., 100 Ω in series with output) is recommended to preserve step response fidelity and prevent peaking.
How does the 14-pin TSSOP package of TLV2404AIDR compare thermally to SOIC?
TLV2404AIDR in TSSOP-14 (PW) has a junction-to-ambient thermal resistance (θJA) of 173.6°C/W, compared to 259.9°C/W for MSOP-8 variants and 122.6°C/W for SOIC-14. Its lower θJA enables higher power dissipation (720 mW at 25°C ambient) and better thermal stability in compact, high-density PCB layouts - critical for multi-channel sensor hubs.
