Product details
Overview
TLV2404CPW 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, 5.5 kHz gain bandwidth product, and supports input voltages up to VCC + 5 V - enabling use in Li-ion–powered sensor front-ends and ultra-low-power industrial monitoring systems.
For engineers reviewing the TLV2404CPW datasheet, TLV2404CPW pinout, TLV2404CPW application, or TLV2404CPW equivalent, key selection criteria include micro-power operation (<1 µA/ch), rail-to-rail I/O swing, reverse-battery fault tolerance, and guaranteed performance across 0°C to 70°C commercial temperature range in TSSOP-14 packaging.
Technical Context
The TLV2404CPW employs a dual-differential input stage (PNP + NPN emitter followers) to achieve rail-to-rail input operation and tolerate inputs up to VCC + 5 V without damage. Its output stage delivers rail-to-rail swing with ±200 µA drive capability into high-impedance loads.
Internal reverse-battery protection uses integrated Schottky diodes to limit reverse supply current to <100 nA at 25°C when VCC = –18 V, enabling direct battery connection in portable equipment without external protection circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad micro-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404IDR | Same architecture and specs, but rated for –40°C to 125°C industrial temperature range; TSSOP-14 package, tape-and-reel only | Required for automotive cabin modules or outdoor utility meters where extended temperature operation is mandatory | Select TLV2404IDR when ambient operating temperature exceeds 70°C or AEC-Q200 qualification is needed |
| LP324DT | Quad 1 µA/ch op-amp (STMicroelectronics); no reverse-battery protection; 10 kHz GBW; 1.5 mV VIO max; SO-14 package | Suitable for cost-sensitive industrial controls where reverse polarity risk is mitigated externally | Choose LP324DT only if reverse-battery protection is implemented at board level and higher offset voltage is acceptable |
Compared with TLV2404CPW, TLV2404IDR offers extended temperature reliability at identical electrical performance, while LP324DT trades reverse-battery immunity and lower offset for lower unit cost and marginally higher bandwidth - making TLV2404CPW optimal for unattended, battery-critical applications.

FAQ
What is the maximum supply voltage rating for TLV2404CPW?
The absolute maximum supply voltage for TLV2404CPW is 17 V. The recommended operating range is 2.5 V to 16 V. Exceeding 17 V risks permanent damage. At 16 V, the device maintains full rail-to-rail input/output operation and specified DC accuracy, including 390 µV typical offset voltage and 120 dB CMRR.
Does TLV2404CPW support true rail-to-rail input and output?
Yes, TLV2404CPW 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 (PNP + NPN) enables operation beyond the positive rail - a key differentiator versus standard rail-to-rail op-amps - and ensures phase stability even with overvoltage transients.
Can TLV2404CPW be used with lithium-ion batteries directly?
Yes, TLV2404CPW is explicitly designed for Li-ion battery systems: its 2.5 V minimum supply allows operation down to battery discharge termination (~2.7 V), and its reverse-battery protection withstands –18 V - covering accidental reverse insertion during battery replacement. No external protection diode is required.
What is the input bias current specification for TLV2404CPW at 25°C?
The input bias current for TLV2404CPW is 100 pA typical and ≤350 pA maximum at 25°C (C-suffix). This ultra-low value enables high-impedance sensor interfacing - such as thermistors or pH electrodes - without significant voltage drop across feedback or source resistors, preserving measurement accuracy.
Is TLV2404CPW pin-compatible with other quad op-amps in TSSOP-14?
No, TLV2404CPW has a unique pinout optimized for quad-channel independence and supply decoupling (dual VCC pins at Pins 4 and 12, GND at Pin 8). It is not pin-compatible with generic TSSOP-14 quad op-amps like LM324 or MCP6004. PCB layout must follow the documented TLV2404CPW pin mapping to ensure correct channel routing and power integrity.
