Product details
Overview
TLV2404IPWRG4 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, reverse battery protection up to –18 V, and operates from 2.5 V to 16 V with input common-mode range extending 5 V beyond VCC. It is used in precision analog front-ends for portable gas sensors and low-power data loggers.
For engineers reviewing the TLV2404IPWRG4 datasheet, TLV2404IPWRG4 pinout, TLV2404IPWRG4 application, or TLV2404IPWRG4 equivalent, key selection criteria include its sub-1-µA quiescent current, rail-to-rail I/O swing at 2.7 V, 1500 µV max input offset voltage over temperature, and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2404IPWRG4 employs a dual-differential input stage (PNP + NPN emitter-follower buffered) enabling rail-to-rail input operation and 5-V-over-the-rail tolerance. Its internal architecture includes integrated Schottky diode protection for reverse-battery resilience up to –18 V, with leakage limited to <100 nA at 25°C.
DC accuracy is maintained via low input bias current (≤900 pA over temperature), high open-loop gain (≥30 V/mV at 5 V), and CMRR ≥63 dB across the full industrial temperature range (–40°C to 125°C). The device is specified at 2.7 V, 5 V, and 15 V supply points with guaranteed performance down to 2.5 V.

Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, 14-pin surface-mount, moisture sensitivity level 1 (MSL-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - rail-to-rail swing supports full-scale ADC input without level-shifting |
| 2 | 1IN– | Inverting input of Channel 1 - high-impedance node requiring guarded layout for <100-pF stray capacitance |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts signals from –0.1 V to VCC + 5 V without damage or phase reversal |
| 4 | VCC | Positive supply rail - decoupling requires 0.1 µF ceramic capacitor placed ≤2.5 mm from pin |
| 5 | 2IN+ | Non-inverting input of Channel 2 - identical electrical behavior to Pin 3; supports independent sensor channels |
| 6 | 2IN– | Inverting input of Channel 2 - matched to Pin 2 for differential pair stability and common-mode rejection |
| 7 | 2OUT | Output of Channel 2 - electrically isolated from Channel 1; crosstalk < –40 dB at 1 kHz |
| 8 | GND | Analog ground reference - must connect to solid ground plane; no split-ground routing permitted |
| 9 | 3OUT | Output of Channel 3 - shares same die substrate as Channels 1 & 2; thermal coupling affects offset drift matching |

| 11 | 3IN+ | Non-inverting input of Channel 3 - supports single-ended or differential configurations with external feedback |
| 12 | VCC | Positive supply rail (redundant connection) - required for thermal derating in high-power-density layouts |
| 13 | 4IN+ | Non-inverting input of Channel 4 - enables four independent low-power signal paths on one IC |
| 14 | 4IN– | Inverting input of Channel 4 - fully characterized for unity-gain stable operation with 100-pF capacitive load |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2404IDR | Same silicon, SOIC-14 package (5.0 mm × 6.2 mm), higher θJA (122.6°C/W) vs TSSOP-14 (173.6°C/W) | Better thermal margin in high-ambient industrial enclosures; larger footprint limits high-density portable designs | Select TLV2404IDR when board space permits and thermal management prioritizes convection over conduction |
| LPV821DRXT | Lower supply current (650 nA), but only single-channel; no reverse-battery protection; 1.7-V min supply | Suitable for ultra-long-life single-sensor nodes, but requires four devices and external protection for quad functionality | Choose LPV821DRXT only when absolute minimum current dominates and reverse-polarity risk is mitigated elsewhere |
Compared with TLV2404IPWRG4, TLV2404IDR offers identical electrical specs in a thermally robust SOIC package ideal for fixed installations, while LPV821DRXT trades integration and protection for lower per-channel current-making TLV2404IPWRG4 optimal for space-constrained, safety-critical quad-sensing applications.

FAQ
What is the maximum supply voltage rating for TLV2404IPWRG4?
The absolute maximum supply voltage for TLV2404IPWRG4 is 17 V. However, the recommended operating range is 2.5 V to 16 V. Operation above 16 V risks permanent damage, and electrical specifications are not guaranteed beyond this limit. The device's reverse-battery protection applies only to negative supply conditions (down to –18 V), not positive overvoltage.
Does TLV2404IPWRG4 support true rail-to-rail input at 2.7 V supply?
Yes, TLV2404IPWRG4 supports rail-to-rail input operation at 2.7 V supply, with common-mode range specified from –0.1 V to VCC + 5 V. At 2.7 V, inputs can swing from –0.1 V to +7.7 V without damage or phase inversion. This is enabled by its hybrid PNP/NPN input stage, which maintains functionality even when inputs exceed the positive rail.
Can TLV2404IPWRG4 drive a 100-pF capacitive load stably?
Yes, TLV2404IPWRG4 is unity-gain stable with up to 100-pF capacitive load, as confirmed by phase margin ≥60° and gain margin ≥15 dB in the datasheet (Figure 24). For reliable operation, maintain PCB trace lengths to the load <5 mm and use local 0.1-µF ceramic decoupling at the VCC pin.
What is the input bias current specification for TLV2404IPWRG4 over temperature?
The input bias current for TLV2404IPWRG4 is ≤900 pA over the full industrial temperature range (–40°C to 125°C). At 25°C, typical value is 100 pA. This ultra-low bias enables use with high-value feedback resistors (>10 MΩ) in precision sensor interfaces without significant offset error.
Is TLV2404IPWRG4 pin-compatible with standard quad op-amp footprints like LM324?
No, TLV2404IPWRG4 uses a TSSOP-14 package with non-standard pinout: it places all four outputs (Pins 1, 7, 9, 14) and inputs (Pins 2–3, 5–6, 10–11, 13–14) in sequence rather than the LM324's interleaved configuration. Direct replacement requires PCB redesign; refer to Figure "TLV2404 D, N, OR PW PACKAGE" in SLOS244B for exact mapping.
