Product details
Overview
TLV2401ID from Texas Instruments is a single-channel, rail-to-rail input/output micro-power operational amplifier with reverse battery protection up to 18 V. It delivers 880 nA supply current per channel, 5.5 kHz gain bandwidth, ±200 µA output drive, and operates from 2.5 V to 16 V - enabling ultra-low-power sensor signal conditioning in battery-powered industrial monitoring systems.
For engineers reviewing the TLV2401ID datasheet, TLV2401ID pinout, TLV2401ID application, or TLV2401ID equivalent, this page provides verified electrical specifications, SOT-23-5 package details, industrial-grade (–40°C to 125°C) performance data, and real-world design guidance for precision low-power analog front-ends.
Technical Context
The TLV2401ID uses a dual-input-stage architecture: a PNP differential pair active from –0.1 V to VCC – 0.8 V, and NPN emitter followers plus a second PNP pair enabling operation up to VCC + 5 V. This supports over-rail input handling without damage while maintaining rail-to-rail output swing.
Reverse battery protection is implemented via internal Schottky diode networks, limiting reverse supply current to ≤50 nA at –18 V and 25°C. Input bias current remains ≤900 pA across the full industrial temperature range, supporting high-impedance sensor interfacing with megaohm-level feedback networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 880 nA/channel at 2.7 V/5 V - enables >10-year battery life in coin-cell-powered IoT sensors |
| Input Offset Voltage | Max 1500 µV over –40°C to 125°C - ensures <1 mV error in 12-bit ADC front-ends at 3.3 V |
| Gain Bandwidth Product | 5.5 kHz - suitable for DC-coupled sensor amplification and slow-varying process signals |
| Rail-to-Rail I/O | Input common-mode range: –0.1 V to VCC + 5 V; output swing within 180 mV of rails - maximizes dynamic range in single-supply systems |
| Reverse Battery Protection | Withstands –18 V supply reversal with <50 nA leakage - eliminates need for external series diodes in automotive/industrial battery interfaces |
| Operating Temperature | –40°C to 125°C (I-suffix) - qualified for under-hood automotive, motor control, and industrial PLC environments |
| Input Bias Current | ≤900 pA over full temperature range - enables use with ≥10 MΩ source impedances without significant voltage error |
Pinout & Package
TLV2401ID is housed in a 5-pin SOT-23 (DBV) package with exposed pad not electrically connected. The device uses standard SOT-23 footprint and thermal characteristics (θJA = 324.1°C/W, θJC = 55°C/W), supporting reflow-compatible assembly and 77.1 mW max power dissipation at 125°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN– | Inverting input | High-impedance node accepting signals up to VCC + 5 V; bias current ≤900 pA enables direct connection to high-Z sources |
| 2 - IN+ | Non-inverting input | Same over-rail capability as IN–; used for unity-gain buffers or non-inverting configurations with minimal offset error |
| 3 - GND | Analog ground reference | Single ground pin shared by input and output stages; requires low-inductance PCB ground plane for stability |
| 4 - VCC | Positive supply | Accepts 2.5 V to 16 V; reverse-battery protected - safe for accidental polarity reversal in field-deployed equipment |
| 5 - OUT | Amplifier output | Rail-to-rail capable; drives ±200 µA into loads; output voltage limited to 180 mV above GND or below VCC at full load |
Key Features
| Feature | Design Value |
|---|---|
| Micro-power operation | 880 nA/channel supply current enables multi-year operation on CR2032 batteries in wireless sensor nodes |
| Over-rail input capability | Inputs tolerate –0.1 V to VCC + 5 V - allows direct interface to unregulated battery rails or overvoltage transients without clamping diodes |
| Industrial temperature grade | Specified from –40°C to 125°C - supports deployment in engine compartments, factory floors, and outdoor metering enclosures |
| Low input offset drift | 3 µV/°C typical offset voltage drift - maintains accuracy across wide ambient temperature swings without recalibration |
| High CMRR | Min 63 dB over full temperature range - rejects common-mode noise in noisy industrial 24 V DC systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2401CD | Commercial-grade (0°C to 70°C); identical electrical specs except wider temp range tolerance on VIO and PSRR | Not rated for under-hood or industrial ambient extremes; unsuitable for deployments exceeding 70°C | Select TLV2401CD only for cost-sensitive consumer electronics with controlled indoor environments |
| LPV801MG | Lower supply current (320 nA), lower GBW (1.9 kHz), no over-rail input (–0.1 V to VCC – 0.2 V), no reverse-battery protection | Lacks robustness for automotive or harsh industrial use; requires external protection circuitry | Choose LPV801MG only when ultra-low power dominates over fault tolerance and input voltage range |
Compared with TLV2401CD and LPV801MG, TLV2401ID uniquely combines industrial temperature rating, 18-V reverse-battery immunity, and VCC + 5 V input tolerance - making it the sole option for unattended, high-reliability analog sensing in adverse conditions without added protection components.

FAQ
What is the maximum supply voltage for TLV2401ID?
The absolute maximum supply voltage for TLV2401ID is 17 V, but the recommended operating range is 2.5 V to 16 V. Operation at 16 V is fully characterized across the industrial temperature range (–40°C to 125°C), with key parameters including open-loop gain (≥120 V/mV), PSRR (≥100 dB), and output drive (±200 µA) confirmed at this voltage.
Does TLV2401ID support rail-to-rail input beyond the positive supply rail?
Yes, TLV2401ID supports input voltages up to VCC + 5 V - verified in the datasheet's "Common-mode input voltage range" specification (–0.1 V to VCC + 5 V). This over-rail capability is enabled by its dual-input-stage architecture and allows direct interfacing with unregulated battery rails or transient overvoltages without external clamping.
What is the reverse battery protection limit for TLV2401ID?
TLV2401ID provides reverse battery protection up to –18 V, with reverse supply current limited to ≤50 nA at 25°C (inputs grounded, outputs open). This protection is intrinsic and requires no external components - a key differentiator for automotive and industrial battery-powered designs where incorrect battery installation may occur.
Can TLV2401ID drive a 10 kΩ load rail-to-rail?
Yes, TLV2401ID maintains rail-to-rail output swing into 10 kΩ loads. At VCC = 5 V and IOL = 50 µA, VOL is ≤230 mV; at IOH = –50 µA, VOH is ≥4.90 V. These values confirm full output compliance across the specified industrial temperature range, supporting accurate ADC interfacing without level-shifting.
Is TLV2401ID pin-compatible with other SOT-23 op-amps?
No, TLV2401ID uses a non-standard SOT-23 pinout: Pin 1 = IN–, Pin 2 = IN+, Pin 3 = GND, Pin 4 = VCC, Pin 5 = OUT. This differs from industry-standard pinouts (e.g., MCP6001, LMV321), so PCB layout must follow the TLV2401ID-specific assignment shown in the official datasheet Figure 3 (DBV package top view).
