Product details
Overview
TLV2401IDBVT 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 ultra-low-power sensor signal conditioning in Li-ion–powered portable instrumentation and industrial monitoring systems.
For engineers reviewing the TLV2401IDBVT datasheet, TLV2401IDBVT pinout, TLV2401IDBVT application, or TLV2401IDBVT equivalent, key selection criteria include its sub-1 µA quiescent current, ±20 V differential input voltage tolerance, –0.1 V to VCC + 5 V common-mode range, and guaranteed operation across –40°C to 125°C industrial temperature range.
Technical Context
The TLV2401IDBVT employs a dual-differential-pair input stage (PNP + NPN emitter followers) to achieve rail-to-rail input operation and 5 V over-the-rail capability. Its internal reverse-battery protection relies on six integrated Schottky diodes, limiting reverse supply current to ≤50 nA at –18 V and 25°C.
DC precision is maintained via low input offset voltage (390 µV typical), high CMRR (120 dB), and open-loop gain ≥130 V/mV at 2.7 V. Output drive capability supports ±200 µA into loads while maintaining rail-to-rail swing under light loading (≤2 µA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2241IDBVT | 1 µA/channel supply current; 5 kHz GBW; no reverse-battery protection; 2.5–12 V supply range. | Lacks overvoltage robustness for battery-reversal-prone environments; lower input voltage range limits over-rail sensing. | Select when reverse-battery risk is absent and slightly higher power budget permits. |
| OPA348AIDBVR | 45 µA/channel supply current; 1 MHz GBW; rail-to-rail I/O; no reverse-battery protection; 2.1–5.5 V supply. | Higher speed and noise performance but incompatible with >5.5 V supplies or reverse-battery scenarios. | Choose for higher-bandwidth sensor interfaces where battery reversal is mitigated externally. |
Compared with TLV2401IDBVT, TLV2241IDBVT trades reverse-battery protection for marginally lower cost and similar ultra-low-power operation, while OPA348AIDBVR offers 180× higher bandwidth at 50× higher supply current - making TLV2401IDBVT uniquely suited for long-life, fault-tolerant, low-frequency analog front-ends.

FAQ
What is the maximum supply voltage for TLV2401IDBVT?
The absolute maximum supply voltage for TLV2401IDBVT is 17 V, with recommended continuous operation up to 16 V. Exceeding 16 V risks parametric degradation or permanent damage. The device is rated for reverse supply voltages down to –18 V, where it draws <50 nA, thanks to integrated Schottky diode protection.
Does TLV2401IDBVT support rail-to-rail output swing at full load?
TLV2401IDBVT achieves rail-to-rail output swing only under light load conditions (≤2 µA). At ±50 µA load, VOL is ≤230 mV and VOH is ≥VCC – 180 mV. For full rail compliance, keep output current below 2 µA or add external buffering - critical for driving high-impedance ADC inputs without headroom loss.
Can TLV2401IDBVT operate from a 2.5 V supply while maintaining specified performance?
Yes. TLV2401IDBVT is fully specified at 2.7 V, 5 V, and 15 V, and guaranteed functional down to 2.5 V. At 2.5 V, gain bandwidth remains ≥5.5 kHz, supply current stays ≤1.29 µA (full temp range), and rail-to-rail I/O functionality is preserved - making it compatible with single Li-ion cells (2.7–4.2 V) and low-voltage microcontrollers like MSP430.
What is the input common-mode voltage range of TLV2401IDBVT?
The input common-mode voltage range of TLV2401IDBVT is –0.1 V to VCC + 5 V. This allows the device to accept signals 5 V above the positive supply rail - useful for overvoltage-tolerant sensor interfaces - and operate with inputs slightly below ground, though phase inversion may occur below –0.1 V.
Is TLV2401IDBVT pin-compatible with other members of the TLV240x family?
No. TLV2401IDBVT (SOT-23-5) is not pin-compatible with TLV2402 (MSOP-8) or TLV2404 (TSSOP-14). While functionally identical per channel, package pinouts differ significantly - e.g., TLV2401 uses pins 1–5 for IN–, IN+, GND, VCC, OUT, whereas TLV2402 places GND on pin 4 and adds NC pins. PCB layout must be tailored to DBV package.
