Product details
Overview
TLV2404IDR from Texas Instruments is a quad rail-to-rail input/output operational amplifier with 880 nA per channel supply current, reverse battery protection up to 18 V, and operation from 2.5 V to 16 V. It features 390 µV typical input offset voltage, 120 dB CMRR, and 5.5 kHz gain bandwidth-enabling ultra-low-power sensor signal conditioning in battery-powered industrial monitoring systems.
For engineers reviewing the TLV2404IDR datasheet, TLV2404IDR pinout, TLV2404IDR application, or TLV2404IDR equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use cases for harsh-environment analog front-ends, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TLV2404IDR uses a dual-differential-input architecture: a PNP pair handles common-mode inputs from –0.1 V to VCC – 0.8 V, while NPN emitter followers extend input range to VCC + 5 V. This enables robust operation during overvoltage transients without latch-up.
Its 880 nA/channel quiescent current is maintained across 2.5–16 V supply range, with reverse supply current limited to 50 nA at –18 V-ensuring survivability in miswired battery systems. Output drives ±200 µA while maintaining rail-to-rail swing within 180 mV of rails at 50 µA load.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404CDR | Commercial-grade (0°C to 70°C); identical electrical specs except wider VIO max (1500 µV vs 1500 µV) and no extended temp validation | Suitable only for indoor consumer electronics; not rated for automotive or industrial ambient extremes | Select TLV2404CDR only when cost sensitivity outweighs temperature robustness requirements |
| LPV821DRX | Lower supply current (320 nA), lower GBW (1.6 kHz), no reverse battery protection, but higher precision (100 µV VIO max) | Better for ultra-long-life static sensors; unsuitable for battery-reversal-prone environments like automotive jump-start scenarios | Choose LPV821DRX when micro-power priority exceeds fault tolerance and bandwidth needs are <2 kHz |
Compared with TLV2404CDR, the TLV2404IDR provides guaranteed operation at –40°C and +125°C with identical micro-power and rail-to-rail performance; versus LPV821DRX, it trades 520 nA higher supply current for 18 V reverse protection and 3.9× higher bandwidth-critical for transient-rich industrial sensing.

FAQ
What is the maximum supply voltage for TLV2404IDR?
The absolute maximum supply voltage for TLV2404IDR is 17 V, with recommended operation from 2.5 V to 16 V. Exceeding 17 V risks permanent damage. The device maintains specified performance across this full 2.5–16 V range, including 2.5 V compatibility with Li-ion single-cell systems. TLV2404IDR's reverse battery protection remains active up to –18 V on VCC.
Does TLV2404IDR support rail-to-rail input beyond the positive supply rail?
Yes, TLV2404IDR supports common-mode input voltages up to VCC + 5 V, verified across its full temperature range. This is achieved via an NPN emitter-follower structure that transitions to diode conduction above VCC, enabling direct interfacing with overvoltage sensors or 5 V logic without level-shifting. TLV2404IDR maintains functionality and specified input bias current up to this limit.
What is the input offset voltage specification for TLV2404IDR?
TLV2404IDR has a typical input offset voltage of 390 µV at 25°C and a maximum of 1500 µV across the full industrial temperature range (–40°C to +125°C). This is measured with VO = VCC/2 and VIC = VCC/2. The offset voltage drift is 3 µV/°C, ensuring predictable DC error accumulation in thermally varying environments.
Can TLV2404IDR be used in a single-supply 3.3 V system?
Yes, TLV2404IDR is fully specified and characterized for 3.3 V operation (within its 2.5–16 V range). At 3.3 V, it delivers rail-to-rail input (–0.1 V to 8.3 V) and output (within 180 mV of rails), 880 nA/channel supply current, and 120 dB CMRR-making it ideal for interfacing with 3.3 V microcontrollers and ADCs in portable instrumentation. TLV2404IDR requires no design derating at this voltage.
What package type is used for TLV2404IDR?
TLV2404IDR is supplied in a 14-pin TSSOP (PW) package with 0.65 mm lead pitch, 5.0 mm × 4.4 mm body dimensions, and thermal pad. This RoHS-compliant surface-mount package supports automated assembly and provides superior thermal performance versus SOIC for the same pin count. TLV2404IDR's pinout matches industry-standard quad op-amp layouts for drop-in compatibility in existing designs.
