Product details
Overview
TLV2401CDBVT 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 data acquisition systems.
For engineers reviewing the TLV2401CDBVT datasheet, TLV2401CDBVT pinout, TLV2401CDBVT application, or TLV2401CDBVT equivalent, key selection criteria include its sub-1-µA quiescent current, ±20 V differential input voltage rating, –0.1 V to VCC+5 V common-mode range, and guaranteed operation across 0°C to 70°C commercial temperature range.
Technical Context
The TLV2401CDBVT employs a dual-differential-pair input stage (PNP + NPN emitter followers) to achieve rail-to-rail input operation and 5 V over-the-rail tolerance. Its output stage uses complementary push-pull circuitry for true rail-to-rail swing with ±200 µA drive capability.
Reverse battery protection is implemented via integrated Schottky diode clamping, limiting reverse supply current to ≤100 nA at 25°C when VCC = –18 V. Input bias current remains below 350 pA (typical) across the full 0°C to 70°C range, supporting high-impedance sensor interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 880 nA per channel - enables multi-year battery life in always-on environmental sensors. |
| Gain Bandwidth Product | 5.5 kHz - suitable for DC-coupled signal conditioning and low-frequency sensor amplification. |
| Input Offset Voltage | 390 µV typical - ensures <1 mV total error in 12-bit ADC front-ends with gain ≤10. |
| Common-Mode Range | –0.1 V to VCC+5 V - allows direct connection to overvoltage-tolerant transducers without level-shifting. |
| Supply Voltage Range | 2.5 V to 16 V - supports single-cell Li-ion (2.7–4.2 V), 3.3 V logic, and industrial 12 V rails. |
| Reverse Battery Protection | Up to –18 V - prevents damage during incorrect battery installation in portable instrumentation. |
| Output Drive | ±200 µA into 500 kΩ load - maintains rail-to-rail swing with minimal droop in high-impedance feedback networks. |
Pinout & Package
TLV2401CDBVT is housed in a 5-pin SOT-23 (DBV) package with exposed pad for thermal enhancement. Pin 1 is OUT; Pin 2 is GND; Pin 3 is IN+; Pin 4 is VCC; Pin 5 is IN–. No internal connection on unused pins - consistent with DBV pinout shown in TI SLOS244B Figure 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±200 µA while maintaining linearity. |
| 2 (GND) | Analog ground reference | Primary return path for input bias currents and output load; must be connected to low-impedance ground plane. |
| 3 (IN+) | Non-inverting input | Accepts signals from –0.1 V to VCC+5 V; exhibits <350 pA bias current at 25°C for minimal voltage error in megaohm networks. |
| 4 (VCC) | Positive supply | Supports 2.5–16 V operation; reverse-battery protected to –18 V; requires local 0.1 µF ceramic decoupling. |
| 5 (IN–) | Inverting input | Matches IN+ in common-mode range and bias current; used for precision inverting configurations and active filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in single-supply systems - e.g., 0–2.7 V output swing from 2.7 V supply. |
| 880 nA supply current | Reduces average power to <2.4 µW at 2.7 V - critical for energy-harvesting nodes and coin-cell–powered devices. |
| –0.1 V to VCC+5 V input range | Eliminates need for external level shifters when interfacing with overvoltage sensors or legacy industrial transmitters. |
| 18 V reverse battery protection | Prevents catastrophic failure during field maintenance - no external protection diodes required in battery-powered designs. |
| 120 dB CMRR | Maintains accuracy in noisy environments - rejects >99.999% of common-mode interference in 0–100 Hz sensor signals. |
Applications
| Portable Gas Sensor Front-End | Low-Power Thermistor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2241CDCKR | 1 µA/ch supply current; 5 kHz GBW; no reverse battery protection; 0.6 mV max VIO. | Lacks overvoltage input tolerance and reverse polarity hardening - requires external protection in battery systems. | Select when lower cost is prioritized and reverse-battery risk is mitigated externally. |
| OPA348AIDBVR | 45 µA/ch supply current; 1 MHz GBW; rail-to-rail I/O; no reverse battery protection; 10 µV max VIO. | Higher speed and precision but consumes 50× more current - unsuitable for multi-year battery life. | Select when higher bandwidth (>100 kHz) and lower offset (<100 µV) outweigh ultra-low-power requirements. |
Compared with TLV2401CDBVT, TLV2241CDCKR offers lower cost but sacrifices reverse-battery hardening and overvoltage input tolerance, while OPA348AIDBVR trades 50× higher supply current for 180× greater bandwidth and 40× lower offset - making each alternative optimal only under distinct system constraints.

FAQ
What is the maximum supply voltage for TLV2401CDBVT?
The absolute maximum supply voltage for TLV2401CDBVT is 17 V, with recommended operation up to 16 V. Exceeding 17 V risks permanent damage. The device is fully specified from 2.5 V to 16 V, including performance validation at 2.7 V, 5 V, and 15 V supply levels per TI SLOS244B datasheet Section 6.
Does TLV2401CDBVT support rail-to-rail input and output simultaneously?
Yes, TLV2401CDBVT supports true rail-to-rail input and output operation: inputs function from –0.1 V to VCC+5 V, and output swings within 180 mV of both rails under 50 µA load. This simultaneous capability enables direct interface with ADCs and sensors operating at the same supply voltage without level-shifting circuitry.
What is the input bias current specification for TLV2401CDBVT at 25°C?
The input bias current for TLV2401CDBVT is 100 pA typical and 350 pA maximum at 25°C (commercial grade, C-suffix), as specified in the "input characteristics" table of TI SLOS244B datasheet. This ultra-low value enables use with >10 MΩ source impedances without significant voltage error.
Can TLV2401CDBVT operate from a single 2.5 V supply?
Yes, TLV2401CDBVT is fully characterized and guaranteed to operate from a minimum supply of 2.5 V, making it compatible with deeply discharged Li-ion cells and low-voltage microcontrollers like the MSP430. Electrical parameters including GBW, VIO, and CMRR are validated at 2.7 V, confirming robust functionality at the 2.5 V lower limit.
Is TLV2401CDBVT pin-compatible with other members of the TLV240x family?
No - TLV2401CDBVT (SOT-23, 5-pin) is not pin-compatible with TLV2402 (MSOP-8) or TLV2404 (TSSOP-14). Each variant has distinct pin counts and layouts. However, all share identical electrical specifications and functional behavior, allowing schematic reuse with board layout adaptation for channel count scaling.
