Product details
Overview
TLV2401IP 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/channel supply current, 5.5 kHz gain bandwidth, and operates from 2.5 V to 16 V - enabling use in Li-ion–powered sensor nodes and ultra-low-power industrial monitoring systems.
For engineers reviewing the TLV2401IP datasheet, TLV2401IP pinout, TLV2401IP application, or TLV2401IP equivalent, this page provides verified specifications, validated SOT-23 pin mapping, real-world use cases in battery-backed instrumentation, and two confirmed alternative op-amps for low-quiescent-current signal conditioning.
Technical Context
The TLV2401IP employs a hybrid PNP/NPN input stage enabling rail-to-rail input operation with common-mode range extending –0.1 V to VCC + 5 V. Its reverse-battery protection relies on integrated Schottky diode clamping, limiting reverse supply current to ≤100 nA at 25°C when VCC = –18 V.
DC precision is maintained via 390 µV typical input offset voltage, 120 dB CMRR, and 130 V/mV open-loop gain at 2.7 V. Output drive capability supports ±200 µA into loads, with rail-to-rail output swing delivering >2.65 V high-level and <180 mV low-level voltage at 2.7 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 880 nA/channel - enables multi-year battery life in always-on environmental sensors. |
| Gain Bandwidth Product | 5.5 kHz - suitable for DC-coupled sensor amplification and slow-varying process signals. |

| 3 | IN+ | Non-inverting input; same overvoltage tolerance as IN–; critical for high-side sensing. |
| 4 | GND | Analog ground reference; must be connected to system ground plane for noise immunity. |
| 5 | NC | No internal connection - left unconnected; no routing or termination required. |
| 6 | VCC | Positive supply input; supports 2.5–16 V; reverse-battery protected up to –18 V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent-current operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2241IDR | 1 µA/channel supply current; 5 kHz GBW; no reverse-battery protection; 2.5–12 V supply. | Lacks –18 V reverse-voltage tolerance; requires external protection diode in battery-reversal-prone designs. | Choose when reverse-battery risk is absent and slightly higher IQ is acceptable for improved AC performance. |
| LPV511MG/NOPB | 322 nA/channel; 6.2 kHz GBW; rail-to-rail I/O; no reverse-battery protection; 1.8–5.5 V supply only. | Not rated for >5.5 V operation or reverse-voltage conditions; unsuitable for 12 V industrial or automotive use. | Prefer only in sub-5.5 V battery systems where absolute lowest IQ outweighs voltage and protection requirements. |
Compared with TLV2401IP, TLV2241IDR trades reverse-battery robustness for marginally better bandwidth, while LPV511MG/NOPB achieves lower IQ but sacrifices voltage range and fault protection - making TLV2401IP uniquely suited for wide-supply, harsh-environment micro-power amplification.

FAQ
What is the maximum supply voltage for TLV2401IP?
The absolute maximum supply voltage for TLV2401IP 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 is fully specified - enabling compatibility with aging Li-ion cells and low-voltage microcontrollers. Electrical characteristics are guaranteed at 2.7 V, 5 V, and 15 V.
Does TLV2401IP support rail-to-rail input and output simultaneously?
Yes, TLV2401IP supports true rail-to-rail input and output operation. Its input common-mode range extends from –0.1 V to VCC + 5 V, and its output swings within 180 mV of both rails under load. This allows full utilization of supply voltage headroom in single-supply configurations - critical for maximizing ADC resolution in low-voltage sensor systems.
How does reverse battery protection work in TLV2401IP?
TLV2401IP incorporates internal Schottky diode clamping that limits reverse supply current to ≤100 nA at 25°C when VCC = –18 V. This prevents latch-up or permanent damage during incorrect battery installation. The protection is intrinsic - no external diodes or fuses are required - simplifying PCB layout and improving field reliability in consumer and industrial battery-powered devices.
What is the input offset voltage specification for TLV2401IP?
TLV2401IP has a typical input offset voltage of 390 µV and a maximum of 1500 µV across the full operating temperature range (–40°C to 125°C). This specification is measured with VO = VCC/2 and applies to both C- and I-suffix variants. Low offset enables accurate amplification of millivolt-level sensor outputs without trimming.
Is TLV2401IP pin-compatible with other members of the TLV240x family?
No, TLV2401IP (8-pin PDIP) is not pin-compatible with TLV2401DBV (5-pin SOT-23) or TLV2402IDGK (8-pin MSOP). While all share identical electrical functionality, package footprints and pinouts differ: TLV2401IP uses pins 1–4 and 6–8 with NC on pins 5, 7, and 8, whereas SOT-23 and MSOP variants assign active functions to all pins. Board redesign is required when substituting packages.
