Product details
Overview
TLV2404AIPWR from Texas Instruments is a quad, rail-to-rail input/output operational amplifier with micro-power operation (880 nA per channel), reverse battery protection up to 18 V, and extended common-mode input range (–0.1 V to VCC + 5 V). It operates from 2.5 V to 16 V and delivers 5.5 kHz gain bandwidth, making it suitable for ultra-low-power sensor signal conditioning in battery-powered industrial monitoring systems.
For engineers reviewing the TLV2404AIPWR datasheet, TLV2404AIPWR pinout, TLV2404AIPWR application, or TLV2404AIPWR equivalent, key selection criteria include its sub-1-µA supply current per channel, rail-to-rail I/O swing, –40°C to 125°C industrial temperature grade, 1500 µV max input offset voltage, and TSSOP-14 package compatibility with high-density PCB layouts.
Technical Context
The TLV2404AIPWR employs a dual-differential-pair input stage (PNP + NPN emitter followers) enabling true rail-to-rail input operation and 5-V over-the-rail tolerance. Its output stage uses complementary push-pull circuitry to achieve rail-to-rail output swing with ±200 µA drive capability.
Reverse battery protection is implemented via integrated Schottky diode structures, limiting reverse supply current to ≤100 nA at 25°C when VCC = –18 V. The amplifier maintains stable operation across 2.5–16 V single-supply or ±1.25–±8 V split-supply configurations, with electrical specifications guaranteed at 2.7 V, 5 V, and 15 V.

FAQ
What is the maximum supply voltage for TLV2404AIPWR?
The absolute maximum supply voltage for TLV2404AIPWR is 17 V, with recommended operation from 2.5 V to 16 V. Exceeding 16 V risks parametric degradation, while operation below 2.5 V may cause loss of rail-to-rail output swing and increased input offset voltage drift. Electrical characteristics are fully specified at 2.7 V, 5 V, and 15 V.
Does TLV2404AIPWR support true rail-to-rail input operation?
Yes, TLV2404AIPWR supports true rail-to-rail input operation from –0.1 V to VCC + 5 V. This is achieved via a hybrid PNP/NPN input stage that transitions seamlessly between modes. At inputs above VCC, the NPN emitters function as diodes, maintaining functionality while increasing input bias current - a documented behavior confirmed in the SLOS244B datasheet Figure 5.
How does reverse battery protection work in TLV2404AIPWR?
TLV2404AIPWR incorporates six integrated Schottky diodes that limit reverse supply current to ≤100 nA at 25°C when VCC = –18 V (inputs grounded, outputs open). This architecture prevents latch-up and permanent damage during battery misinsertion, eliminating the need for external protection components in portable equipment designs.
What is the input offset voltage specification for TLV2404AIPWR over temperature?
TLV2404AIPWR has a maximum input offset voltage of 1500 µV across its full operating temperature range of –40°C to 125°C. At 25°C, typical VIO is 390 µV, with a drift of 3 µV/°C. This specification is guaranteed for the "I" suffix variant (TLV2404Ixx), which TLV2404AIPWR belongs to per TI's packaging and temperature grade coding.
Can TLV2404AIPWR drive capacitive loads without instability?
TLV2404AIPWR remains stable with capacitive loads up to 100 pF, delivering ≥60° phase margin and ≥15 dB gain margin per Figure 24 and 25 of the SLOS244B datasheet. For loads >100 pF, external isolation resistance (e.g., 10–100 Ω in series with output) is recommended to maintain stability in high-precision applications.
