Product details
Overview
TLV2404CPWR from Texas Instruments is a quad, rail-to-rail input/output operational amplifier optimized for ultra-low-power sensor signal conditioning and battery-powered instrumentation. It delivers 880 nA per channel supply current, ±200 µA output drive, 5.5 kHz gain bandwidth, reverse battery protection up to 18 V, and operates from 2.5 V to 16 V - enabling use in Li-ion–powered portable medical monitors and industrial sensor nodes.
For engineers reviewing the TLV2404CPWR datasheet, TLV2404CPWR pinout, TLV2404CPWR application, or TLV2404CPWR equivalent, this page provides verified electrical specifications, TSSOP-14 package details, real-world use cases in precision analog front-ends, and validated alternative options for low-voltage, micro-power op-amp selection.
Technical Context
The TLV2404CPWR employs 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 rail-to-rail operation up to VCC + 5 V without damage. Its input stage enables over-the-rail sensing in battery-supervised systems where input transients exceed supply rails.
Reverse battery protection is implemented via internal Schottky diode clamping, limiting reverse supply current to <100 nA at 25°C when VCC = –18 V. The device maintains rail-to-rail output swing (within 180 mV of rails at 50 µA load) and achieves 120 dB CMRR at 25°C with 130 V/mV open-loop gain at 2.7 V.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar micro-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404IDR | Same electrical specs but rated for –40°C to 125°C industrial temperature range; TSSOP-14 package identical. | Required for outdoor, automotive under-hood, or high-ambient industrial deployments where 0°C–70°C rating is insufficient. | Select TLV2404IDR when extended temperature operation is mandatory; no PCB changes needed. |
| LPV821DRX | Lower supply current (320 nA), lower offset (150 µV typ), but narrower supply range (1.6 V–5.5 V); SOT-23-5 single-channel only. | Suitable for ultra-low-voltage (1.8 V) systems like energy-harvesting nodes, but requires four separate packages for quad functionality. | Choose LPV821DRX only for new designs targeting <2 V operation and single-channel use; not drop-in compatible with TLV2404CPWR. |
Compared with TLV2404IDR, TLV2404CPWR offers lower cost and commercial-grade qualification for indoor applications; compared with LPV821DRX, it supports higher supply voltages (up to 16 V) and integrated quad topology - reducing component count and board area in multi-sensor systems.

FAQ
What is the maximum supply voltage for TLV2404CPWR, and what happens if exceeded?
The absolute maximum supply voltage for TLV2404CPWR is 17 V. Operation above 16 V violates recommended conditions and risks permanent damage. At 17 V, internal junction temperatures may exceed 150°C even at ambient 25°C due to power dissipation limits - TI specifies 16 V as the maximum safe operating voltage. Exceeding this can cause parametric shift or catastrophic failure.
Does TLV2404CPWR support true rail-to-rail output swing under load?
Yes, TLV2404CPWR delivers rail-to-rail output swing with defined limits: at 50 µA load, VOL is ≤260 mV above GND and VOH is ≥14.93 V below VCC when VCC = 15 V. At lighter loads (2 µA), swing improves to ≤180 mV from rails. This behavior is guaranteed across 0°C to 70°C and enables full utilization of ADC input ranges in low-voltage systems.
Can TLV2404CPWR be used with input signals exceeding VCC, and is it safe?
Yes - TLV2404CPWR safely accepts input voltages up to VCC + 5 V due to its dual-input-stage architecture. When inputs exceed VCC, internal NPN transistors transition into diode conduction, limiting input current without damage. However, input bias current increases above VCC, so external series resistors should limit current to <10 mA per input to avoid ESD structure activation.
What is the typical input offset voltage drift over temperature for TLV2404CPWR?
The typical input offset voltage drift for TLV2404CPWR is 3 µV/°C, measured at 25°C with VCC = 2.7 V. Over the full 0°C to 70°C commercial range, total offset variation remains within ±150 µV of the 25°C value, contributing <0.05% of full-scale error in a 3 V-span measurement - making it suitable for precision DC-coupled sensor interfaces.
Is TLV2404CPWR pin-compatible with other quad op-amps in TSSOP-14 packages?
No - TLV2404CPWR uses a non-standard pinout optimized for low crosstalk and layout symmetry: Channels 1–2 occupy Pins 1–7, GND is Pin 8, and Channels 3–4 occupy Pins 9–14. It is not pin-compatible with generic quad op-amps like LM324 or TLV2464. Layout must follow TI's recommended routing for optimal PSRR and CMRR performance.
