Product details
Overview
TLV2404ID 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, 390 µV typical input offset voltage, and 5.5 kHz unity-gain bandwidth - optimized for ultra-low-power sensor signal conditioning in battery-powered industrial monitoring systems.
For engineers reviewing the TLV2404ID datasheet, TLV2404ID pinout, TLV2404ID application, or TLV2404ID equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in harsh-environment sensing, and confirmed alternative options for micro-power op-amp selection.
Technical Context
The TLV2404ID uses a dual-differential-input architecture: a PNP pair handles common-mode inputs from –0.1 V to VCC – 0.8 V, while NPN emitter followers extend input range up to VCC + 5 V without damage. Its reverse-battery protection relies on internal Schottky diode leakage limiting supply current to <100 nA at –18 V.
DC accuracy is maintained across temperature via 120 dB CMRR and minimum open-loop gain of 30 V/mV over full industrial range (–40°C to 125°C). Output swing reaches within 180 mV of rails at 50 µA load, supporting true single-supply operation in low-voltage data acquisition.
Key Specifications

|---|---|
| Supply Current/Ch | 880 nA typical - enables >10-year battery life in always-on IoT sensor nodes using CR2032 or coin cells. |
| Input Offset Voltage | 390 µV typical - ensures sub-mV error in precision bridge sensor amplification without trimming. |
| Unity-Gain Bandwidth | 5.5 kHz - sufficient for DC–1 kHz sensor signals (e.g., thermistors, strain gauges) with stable phase margin. |
| Rail-to-Rail I/O | Inputs operate from –0.1 V to VCC + 5 V; outputs swing to within 180 mV of rails - maximizes dynamic range in 3.3 V or 5 V systems. |
| Reverse Battery Protection | Withstands –18 V supply reversal with <100 nA current - eliminates need for external blocking diodes in portable equipment. |
| Operating Temp Range | –40°C to +125°C - qualified for under-hood automotive sensors and industrial field transmitters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404CD | Commercial temperature grade (0°C to 70°C); otherwise identical electrical specs and pinout. | Not rated for automotive or industrial environments exceeding 70°C ambient. | Select TLV2404CD only for cost-sensitive consumer electronics with controlled thermal environments. |
| LPV821DRX | Lower supply current (650 nA/ch), but narrower supply range (1.6 V–5.5 V) and no reverse-battery protection. | Limited to 3.3 V systems; unsuitable for 12 V battery backup or automotive 12 V direct connection. | Choose LPV821DRX when ultra-low power dominates and reverse polarity risk is mitigated externally. |
Compared with TLV2404CD and LPV821DRX, the TLV2404ID uniquely combines industrial temperature rating, reverse-battery robustness, and rail-to-rail performance in a single quad op-amp - making it the only option for unattended field-deployed sensors requiring both longevity and fault tolerance.

FAQ
What is the maximum supply voltage for TLV2404ID?
The absolute maximum supply voltage for TLV2404ID is 17 V, with recommended operating range from 2.5 V to 16 V. Exceeding 17 V risks permanent damage. The device maintains specified performance across its full 2.5–16 V range, including stable 5.5 kHz bandwidth and 880 nA supply current at both extremes.
Does TLV2404ID support true rail-to-rail input beyond the supply rails?
Yes, TLV2404ID supports input voltages from –0.1 V to VCC + 5 V - meaning it accepts signals 5 V above the positive supply rail without damage or phase inversion. This over-rail capability eliminates external level shifters when interfacing with sensors biased from higher-voltage supplies.
How does reverse battery protection work in TLV2404ID?
TLV2404ID incorporates internal Schottky diode structures that limit reverse supply current to <100 nA at –18 V and 25°C. During reverse polarity, the device draws negligible current, preventing damage to itself or downstream circuitry - eliminating the need for external series diodes in battery-powered designs.
What is the output drive capability of TLV2404ID?
TLV2404ID delivers ±200 µA output current while maintaining rail-to-rail swing within 180 mV of each supply rail at 50 µA load. This allows direct driving of ADC reference inputs, low-power comparators, or small-signal MOSFET gates without external buffers - critical for minimizing component count in space-constrained designs.
Is TLV2404ID pin-compatible with other quad op-amps in SOIC-14 packages?
No - TLV2404ID follows the standard TI quad op-amp pinout (1OUT, 1IN–, 1IN+, GND, 2IN+, 2IN–, 2OUT, VCC, 3OUT, 3IN–, 3IN+, 4IN+, 4IN–, 4OUT), but functional compatibility requires verification of supply range, input range, and quiescent current. It is not a drop-in replacement for legacy parts like LM324 due to its micro-power architecture and over-rail input design.
