Product details
Overview
TLV2401IDBVTG4 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, and operates from 2.5 V to 16 V supply-enabling use in Li-ion–powered sensor front-ends and ultra-low-power industrial monitoring systems.
For engineers reviewing the TLV2401IDBVTG4 datasheet, TLV2401IDBVTG4 pinout, TLV2401IDBVTG4 application, or TLV2401IDBVTG4 equivalent, key selection criteria include its sub-1-µA quiescent current, –0.1 V to VCC + 5 V input common-mode range, 390 µV typical offset voltage, reverse-battery fault tolerance, and SOT-23-5 packaging for space-constrained designs.
Technical Context
The TLV2401IDBVTG4 employs a dual-differential-input architecture: a PNP pair handles inputs from –0.1 V to VCC – 0.8 V, while NPN emitter followers extend operation up to VCC + 5 V without damage. Its internal Schottky diode network enables reverse-battery protection at –18 V with <100 nA leakage at 25°C.
DC precision is maintained via 120 dB CMRR, 130 V/mV open-loop gain at 2.7 V, and low input bias current (100 pA typ). The device is specified across –40°C to +125°C (I-suffix), with electrical characteristics validated at 2.7 V, 5 V, and 15 V supply voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 880 nA per channel - enables multi-year battery life in always-on IoT sensors and portable medical monitors. |
| Input Common-Mode Range | –0.1 V to VCC + 5 V - supports direct sensing of over-rail transducer outputs and reverse-polarity tolerant front-ends. |
| Gain Bandwidth Product | 5.5 kHz - suitable for DC-coupled signal conditioning, slow-settling sensor interfaces, and low-frequency filtering. |
| Input Offset Voltage | 390 µV typical - ensures <1 mV error in 2.7 V–5 V single-supply systems using high-impedance feedback networks. |
| Reverse Battery Protection | Up to –18 V - prevents destructive current flow during incorrect battery installation in field-deployed equipment. |
| Rail-to-Rail I/O | Full swing input and output - maximizes dynamic range in low-voltage systems (e.g., 2.5 V–3.3 V MCU analog domains). |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor environmental monitoring. |
Pinout & Package
TLV2401IDBVTG4 is housed in a 5-pin SOT-23 (DBV) package with exposed pad for thermal performance. Pin 1 is OUT, Pin 2 is GND, Pin 3 is IN+, Pin 4 is VCC, and Pin 5 is IN–. No internal connection exists on unused pins in alternate packages; DBV uses all five terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±200 µA into high-impedance loads. |
| 2 (GND) | Analog ground reference | Primary return path for input bias currents and output load current; requires low-inductance PCB connection. |
| 3 (IN+) | Non-inverting input | Accepts signals from –0.1 V to VCC + 5 V; exhibits 100 pA typical input bias current at 25°C. |
| 4 (VCC) | Positive supply rail | Supports 2.5 V–16 V operation; reverse-battery protection activates when voltage falls below –18 V. |
| 5 (IN–) | Inverting input | Matches IN+ in common-mode range and bias current; used for precision inverting configurations and feedback networks. |
Key Features
| Feature | Design Value |
|---|---|
| Micro-power operation | 880 nA/channel supply current enables >10-year battery life in coin-cell–powered remote sensors. |
| Over-rail input capability | Inputs tolerate up to VCC + 5 V without latch-up or damage-critical for interfacing with unregulated transducers. |
| Reverse battery protection | Internal Schottky network limits reverse current to <100 nA at –18 V, eliminating need for external series diodes. |
| Rail-to-rail input/output | Full input range (–0.1 V to VCC + 5 V) and output swing (within 180 mV of rails) maximize usable signal headroom. |
| Low input offset voltage | 390 µV typical offset minimizes DC error in high-gain, high-resistance sensor amplifiers (e.g., thermistor bridges). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micro-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2241IDBVR | 1 µA/ch supply current, 5 kHz GBW, no reverse-battery protection, same SOT-23-5 package. | Lacks over-rail input and reverse-polarity hardening; suitable only where battery reversal risk is eliminated by system design. | Select when absolute lowest cost is prioritized and external protection is already implemented. |
| LPV821DBVR | 320 nA/ch supply current, 6.5 kHz GBW, rail-to-rail I/O, no reverse-battery protection, same SOT-23-5 footprint. | Lower power but no reverse-battery tolerance; higher GBW enables faster settling in low-power data loggers. | Choose for extended battery life where reverse polarity is prevented by mechanical or firmware interlocks. |
Compared with TLV2241IDBVR and LPV821DBVR, the TLV2401IDBVTG4 uniquely combines sub-µA operation with integrated –18 V reverse-battery protection and VCC + 5 V input tolerance-making it the only option for unattended, field-serviceable equipment requiring intrinsic fault resilience.

FAQ
What is the maximum supply voltage for TLV2401IDBVTG4?
The absolute maximum supply voltage for TLV2401IDBVTG4 is 17 V, with recommended operation from 2.5 V to 16 V. Exceeding 16 V risks parametric degradation, while operation down to 2.5 V maintains full functionality-including rail-to-rail input/output swing and reverse-battery protection-making TLV2401IDBVTG4 compatible with aging Li-ion cells and low-voltage microcontrollers.
Does TLV2401IDBVTG4 support true rail-to-rail input and output?
Yes, TLV2401IDBVTG4 provides true rail-to-rail input (–0.1 V to VCC + 5 V) and output (within 180 mV of rails at ±200 µA load). Its dual-input-stage architecture-combining PNP and NPN differential pairs-enables operation beyond the positive rail without damage, a capability confirmed in the SLOS244B datasheet Figure 1–3 and Application Information section.
How does reverse battery protection work in TLV2401IDBVTG4?
TLV2401IDBVTG4 integrates six internal Schottky diodes that limit reverse current to <100 nA at –18 V and 25°C. When VCC is reversed, these diodes block conduction paths, preventing destructive current flow through the core amplifier circuitry. This eliminates the need for external series diodes in battery-powered equipment where field wiring errors may occur.
What is the typical input offset voltage of TLV2401IDBVTG4?
The typical input offset voltage of TLV2401IDBVTG4 is 390 µV at 25°C, with a maximum of 1500 µV across the full –40°C to +125°C industrial temperature range. This low offset, combined with 120 dB CMRR and 130 V/mV open-loop gain, ensures high DC accuracy in precision sensor amplifiers using megaohm-level feedback resistors.
Is TLV2401IDBVTG4 pin-compatible with other SOT-23-5 op-amps?
TLV2401IDBVTG4 follows the standard SOT-23-5 pinout (OUT, GND, IN+, VCC, IN–), matching industry conventions for single op-amps in this package. However, functional compatibility requires verification of supply current, bandwidth, offset, and protection features-since TLV2401IDBVTG4's reverse-battery tolerance and over-rail input are not replicated in most generic SOT-23-5 op-amps.
