Product details
Overview
TLV2401CDG4 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 TLV2401CDG4 datasheet, TLV2401CDG4 pinout, TLV2401CDG4 application, or TLV2401CDG4 equivalent, this page provides verified electrical specifications, SOT-23 pin mapping, real-world use cases in battery-critical systems, and validated alternative op-amps for low-quiescent-current signal conditioning.
Technical Context
The TLV2401CDG4 employs a dual-differential-input architecture: a PNP pair active from –0.1 V to VCC – 0.8 V, and NPN emitter followers enabling over-the-rail operation up to VCC + 5 V. Its input stage remains functional under reverse supply (–18 V), drawing only 50 nA typical reverse supply current.
DC precision is maintained via 390 µV typical input offset voltage, 120 dB CMRR at 25°C, and 130 V/mV open-loop gain at 2.7 V. Output swing reaches within 180 mV of rails at 50 µA load, supporting true single-supply signal processing without level-shifting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent-current op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2401IDBVR | Same silicon, –40°C to 125°C extended temperature grade; identical pinout and electrical specs. | Suitable for automotive engine bay or industrial outdoor enclosures where ambient exceeds 70°C. | Select when operating temperature exceeds 70°C; otherwise TLV2401CDG4 offers cost and qualification advantage for commercial-grade designs. |
| LPV801MG/NOPB | Lower 320 nA supply current, but narrower 1.8–5.5 V supply range and no reverse-battery protection. | Limited to sub-5 V battery systems; unsuitable for 9-V or 12-V industrial rails or reverse-polarity risk environments. | Choose LPV801MG/NOPB only for ultra-low-power <5 V applications where reverse protection is not required and extended voltage range is unnecessary. |
Compared with TLV2401IDBVR, TLV2401CDG4 trades extended temperature range for lower cost and commercial qualification; compared with LPV801MG/NOPB, it sacrifices some quiescent current reduction to retain 2.5–16 V flexibility and reverse-battery robustness essential in field-deployed hardware.

FAQ
What is the maximum supply voltage for TLV2401CDG4?
The absolute maximum supply voltage for TLV2401CDG4 is 17 V, with recommended operation from 2.5 V to 16 V. Exceeding 16 V may degrade long-term reliability, and operation below 2.5 V risks loss of rail-to-rail output swing and increased input offset drift. Electrical characteristics are fully specified at 2.7 V, 5 V, and 15 V.
Does TLV2401CDG4 support true rail-to-rail input beyond the supply rails?
Yes - TLV2401CDG4 accepts input common-mode voltages from –0.1 V to VCC + 5 V. This over-the-rail capability is enabled by its dual-input-stage architecture (PNP + NPN followers) and allows direct interfacing with sensors whose output exceeds VCC, such as certain thermocouples or fault-monitoring circuits, without external clamping diodes.
What is the reverse battery protection specification for TLV2401CDG4?
TLV2401CDG4 withstands reverse supply voltages up to –18 V with typical reverse supply current of 50 nA at 25°C (inputs grounded, outputs open). This protection is intrinsic to the IC's internal structure and requires no external components - making it ideal for handheld tools, medical devices, and battery-backed controllers where incorrect battery insertion is a known field failure mode.
Can TLV2401CDG4 drive capacitive loads?
TLV2401CDG4 maintains stability with capacitive loads up to 100 pF, as confirmed by phase margin ≥60° and gain margin ≥15 dB under standard test conditions (RL = 500 kΩ, VCC = 2.7/5/15 V). For loads >100 pF, external isolation resistance (e.g., 10–100 Ω in series with output) is recommended to preserve settling time and prevent peaking.
What is the typical input bias current of TLV2401CDG4 at room temperature?
The typical input bias current of TLV2401CDG4 is 100 pA at 25°C, with a maximum of 350 pA over the full 0°C to 70°C commercial temperature range. This ultra-low value enables accurate amplification in high-impedance sensor interfaces - such as pH electrodes, photodiode transimpedance stages, and thermistor bridges - without significant voltage error from bias current flowing through feedback resistors.
