Product details
Overview
TLV2401CD from Texas Instruments is a single-channel, rail-to-rail input/output micro-power operational amplifier with reverse battery protection. It delivers 880 nA supply current per channel, supports 2.5 V to 16 V supply range, and operates across 0°C to 70°C (Commercial grade). Its –0.1 V to VCC + 5 V input common-mode range and 5.5 kHz gain bandwidth make it suitable for ultra-low-power sensor signal conditioning in battery-powered instrumentation.
For engineers reviewing the TLV2401CD datasheet, TLV2401CD pinout, TLV2401CD application, or TLV2401CD equivalent, key selection criteria include its sub-1 µA quiescent current, reverse-battery tolerance up to 18 V, rail-to-rail I/O swing, low 390 µV typical offset voltage, and SOT-23-5 packaging for space-constrained designs.
Technical Context
The TLV2401CD uses a dual-differential-pair input stage-PMP-based for –0.1 V to VCC – 0.8 V inputs and NPN/PNP hybrid buffering above VCC-enabling 5 V over-the-rail operation without damage. Its output stage employs rail-to-rail complementary push-pull circuitry delivering ±200 µA drive capability into high-impedance loads.
Reverse battery protection is implemented via integrated Schottky diode clamping, limiting reverse supply current to ≤100 nA at 25°C when VCC = –18 V and inputs grounded. The device maintains functional stability with capacitive loads up to 100 pF and exhibits ≥60° phase margin under all specified supply conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2241CD | 1 µA/channel supply current; 5 kHz GBW; no reverse-battery protection | Lacks –18 V reverse-voltage tolerance; requires external protection diode in battery-replaceable systems | Choose TLV2241CD only if reverse-battery risk is absent and 120 nA higher ICC is acceptable |
| LPV511MG/NOPB | 320 nA/channel; 6.5 kHz GBW; rail-to-rail I/O; no over-the-rail input capability | Cannot accept inputs > VCC; lacks VCC + 5 V input range needed for unregulated sensor interfaces | Prefer LPV511MG/NOPB when ultra-low ICC dominates design and input voltage stays within rails |
Compared with TLV2241CD and LPV511MG/NOPB, the TLV2401CD uniquely combines reverse-battery protection, over-the-rail input operation, and sub-1 µA quiescent current-making it the only choice for robust, long-life, single-supply sensor front-ends where input voltage excursions or battery polarity risks exist.

FAQ
What is the maximum supply voltage for TLV2401CD?
The absolute maximum supply voltage for TLV2401CD is 17 V, but the recommended operating range is 2.5 V to 16 V. Operation at 16 V is fully characterized with electrical specifications guaranteed at 2.7 V, 5 V, and 15 V. Exceeding 16 V may compromise long-term reliability even if within absolute maximum ratings.
Does TLV2401CD support true rail-to-rail input and output?
Yes, TLV2401CD supports rail-to-rail input (–0.1 V to VCC + 5 V) and rail-to-rail output (within 180 mV of rails at 50 µA load). Its dual-input-stage architecture enables operation beyond the positive rail, while the output stage delivers full swing from GND to VCC under light loads.
Can TLV2401CD be used with lithium-ion batteries directly?
Yes, TLV2401CD is explicitly designed for Li-ion battery systems: its 2.5 V minimum supply supports discharge down to 2.5 V, and its reverse-battery protection withstands –18 V during incorrect battery insertion-critical for consumer-grade battery compartments where polarity reversal is a known field failure mode.
What is the input bias current specification for TLV2401CD?
The input bias current for TLV2401CD is 100 pA typical and 350 pA maximum over the full 0°C to 70°C commercial temperature range. This ultra-low value minimizes voltage errors across high-value feedback resistors (e.g., >1 MΩ), making TLV2401CD ideal for precision transimpedance and high-impedance source amplification.
Is TLV2401CD pin-compatible with other op-amps in SOIC-8 packages?
No, TLV2401CD uses a 5-pin SOT-23 (DBV) package and is not pin-compatible with SOIC-8 op-amps. Its pinout (OUT, GND, IN+, VCC, IN–) differs fundamentally from standard 8-pin layouts. Migration to SOIC-8 devices like TLV2402CD would require PCB redesign and layout validation due to different pin count, spacing, and thermal characteristics.
