Product details
Overview
TLV2404IPWR 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 390 µV typical input offset voltage, 5.5 kHz gain bandwidth, and ±200 µA output drive-enabling ultra-low-power sensor signal conditioning in battery-powered industrial monitoring systems.
For engineers reviewing the TLV2404IPWR datasheet, TLV2404IPWR pinout, TLV2404IPWR application, or TLV2404IPWR equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options for long-life, low-voltage analog front-ends.
Technical Context
The TLV2404IPWR employs a dual-stage input stage combining PNP and NPN differential pairs to achieve rail-to-rail input operation extending 5 V above VCC and –0.1 V below ground. Its micro-power architecture uses precision biasing to maintain 880 nA/channel supply current across 2.5–16 V while delivering 130 V/mV open-loop gain at 2.7 V.
Reverse battery protection is implemented via integrated Schottky diode structures limiting reverse supply current to <100 nA at –18 V, enabling direct connection to Li-ion or lead-acid batteries without external protection circuitry. Input common-mode range exceeds rails, and output swings within 180 mV of rails at 50 µA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current/Ch | 880 nA typical - enables >10-year battery life in always-on sensor nodes using CR2032 or single AA cells. |
| Input Offset Voltage | 390 µV typical - supports high-accuracy DC-coupled amplification of thermocouple or strain gauge signals without trimming. |
| Gain Bandwidth | 5.5 kHz - sufficient for sub-1 kHz sensor signal conditioning (e.g., pH, gas, temperature) with stable unity-gain operation. |
| Supply Voltage Range | 2.5 V to 16 V - compatible with single Li-ion (2.7–4.2 V), 3.3 V MCU rails, and 12 V industrial buses. |
| Common-Mode Range | –0.1 V to VCC + 5 V - allows direct sensing of signals referenced above supply (e.g., battery voltage monitoring). |
| Output Swing | Within 180 mV of rails at 50 µA - preserves dynamic range in single-supply 3.3 V or 5 V data acquisition systems. |
| PSRR | 100 dB typical at 5 V - rejects ripple from switching regulators in compact portable instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404CDR | Same silicon, SOIC-14 package; higher θJA (122.6°C/W) vs. TSSOP-14 (173.6°C/W); 0°C to 70°C temp grade. | Suitable for commercial-grade cost-sensitive designs where board space and extended temperature are not constraints. | Select TLV2404CDR only if SOIC footprint is preferred and ambient operating temperature stays below 70°C. |
| LPV821DRXT | Lower supply current (650 nA/ch), but narrower supply range (1.6–5.5 V); no reverse battery protection; 1.2 kHz GBW. | Better for sub-3.3 V wearables; unsuitable for 12 V industrial monitoring or battery-reversal-prone environments. | Choose LPV821DRXT only for ultra-low-voltage (≤3.3 V), ultra-low-power wearable sensors - not for TLV2404IPWR's 2.5–16 V or reverse-protection use cases. |
Compared with TLV2404CDR, TLV2404IPWR offers industrial temperature range and superior thermal performance in compact TSSOP; versus LPV821DRXT, it provides wider voltage operation, reverse protection, and higher bandwidth - making it uniquely suited for ruggedized, multi-voltage battery systems.

FAQ
What is the maximum supply voltage rating for TLV2404IPWR?
The absolute maximum supply voltage for TLV2404IPWR is 17 V, with recommended operation from 2.5 V to 16 V. Exceeding 17 V risks permanent damage. Electrical characteristics are specified at 2.7 V, 5 V, and 15 V - ensuring reliable performance across Li-ion, 3.3 V logic, and 12 V industrial rails. TLV2404IPWR maintains rail-to-rail I/O and 880 nA/channel current within this full range.
Does TLV2404IPWR support true rail-to-rail input beyond the supply rails?
Yes, TLV2404IPWR supports input voltages from –0.1 V to VCC + 5 V - enabling direct measurement of signals exceeding the positive rail, such as battery voltage or unregulated supply monitoring. This over-rail capability is achieved via an NPN/PNP composite input stage that transitions gracefully into diode conduction above VCC, maintaining functionality without latch-up. TLV2404IPWR retains 120 dB CMRR and low input bias current even under these conditions.
How does reverse battery protection work in TLV2404IPWR?
TLV2404IPWR integrates six internal Schottky diodes to limit reverse supply current to <100 nA at –18 V and 25°C. When VCC is reversed, these diodes block conduction paths while allowing safe leakage - eliminating the need for external protection components. The feature is intrinsic to the die design and applies across the full –40°C to 125°C temperature range. TLV2404IPWR remains undamaged and resumes normal operation upon restoration of correct polarity.
What is the typical input offset voltage of TLV2404IPWR and how does it affect precision designs?
TLV2404IPWR has a typical input offset voltage of 390 µV (max 1500 µV over temperature), measured at 25°C with VO = VCC/2. This low VIO enables high-accuracy DC amplification - for example, achieving <0.1% gain error in a 100× TIA for 10 nA sensor currents. The offset drift is only 3 µV/°C, minimizing thermal errors in uncalibrated field deployments. TLV2404IPWR's VIO stability supports 12-bit+ resolution in battery-operated data loggers without trimming.
Can TLV2404IPWR drive capacitive loads, and what is its phase margin?
TLV2404IPWR is stable with capacitive loads up to 100 pF, exhibiting 60° phase margin and 15 dB gain margin at 25°C with RL = 500 kΩ and CL = 100 pF. Its internal compensation ensures unity-gain stability without external isolation resistors - critical for driving ADC input capacitance or long PCB traces. For loads >100 pF, a small series resistor (10–50 Ω) at the output restores stability. TLV2404IPWR's robust phase margin prevents oscillation in multi-stage sensor signal chains.
