Product details
Overview
TLV2404IPW from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for ultra-low-power, single-supply operation. It delivers 880 nA per channel supply current, ±10 mA output drive capability, and reverse battery protection up to 18 V, enabling use in Li-ion–powered sensor front-ends and portable medical monitors where supply integrity and micropower operation are critical.
For engineers reviewing the TLV2404IPW datasheet, TLV2404IPW pinout, TLV2404IPW application, or TLV2404IPW equivalent, key selection considerations include its 5.5 kHz gain-bandwidth product, –40°C to 125°C industrial temperature range, rail-to-rail I/O swing at 2.5 V minimum supply, and TSSOP-14 package with verified 14-pin terminal mapping.
Technical Context
The TLV2404IPW employs a dual-differential-pair input stage (PNP + NPN) to achieve rail-to-rail common-mode input range extending 5 V above VCC and –0.1 V below ground. Its internal reverse-battery protection circuitry limits supply current to <100 nA under –18 V reverse bias, preventing damage during battery misconnection in field-deployed equipment.
DC precision is maintained via low 390 µV typical input offset voltage, 120 dB CMRR, and 130 V/mV open-loop gain at 2.7 V - all specified across the full industrial temperature range. The amplifier remains stable driving capacitive loads up to 100 pF without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current / Channel | 880 nA typical - enables >10-year battery life in always-on IoT sensor nodes using CR2032 or coin cells. |
| Gain Bandwidth Product | 5.5 kHz - supports DC-coupled signal conditioning of slow-varying biosignals (ECG, temperature) without instability. |
| Input Offset Voltage | 390 µV typical - ensures sub-mV error in high-gain (≥100×) bridge amplifier configurations for strain gauges. |
| Rail-to-Rail I/O | Operates from VCC = 2.5 V to 16 V with full swing to both rails - eliminates level-shifting in 3.3 V or 5 V microcontroller ADC interfaces. |
| Reverse Battery Protection | Withstands –18 V supply reversal with <100 nA leakage - protects against field-service battery insertion errors in handheld instruments. |
| Common-Mode Input Range | –0.1 V to VCC + 5 V - allows direct sensing of signals referenced above supply (e.g., thermocouple cold-junction bias). |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive sensors and industrial process controllers. |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first op-amp channel - drives high-impedance loads (≥500 kΩ) with rail-to-rail swing. |
| 2 | 1IN– | Inverting input of first channel - accepts differential inputs up to VCC + 5 V without damage. |
| 3 | 1IN+ | Non-inverting input of first channel - supports common-mode voltages down to –0.1 V for ground-referenced sensors. |
| 4 | VCC | Positive supply rail - accepts 2.5 V to 16 V; reverse-battery protection active when negative. |

| 11 | 3IN+ | Non-inverting input of third channel - identical to Pin 3; supports over-rail sensing in battery-monitoring circuits. |
| 12 | VCC | Positive supply rail (duplicate connection) - improves power delivery integrity in high-density layouts. |
| 13 | 4IN+ | Non-inverting input of fourth channel - enables four independent sensor amplifiers on single IC. |

FAQ
What is the maximum supply voltage for TLV2404IPW?
The absolute maximum supply voltage for TLV2404IPW is 17 V, with recommended operation from 2.5 V to 16 V. Exceeding 17 V risks permanent damage. Electrical characteristics are fully specified at 2.7 V, 5 V, and 15 V, and the device maintains rail-to-rail output swing across this entire range. Reverse-battery protection remains active up to –18 V on VCC.
Does TLV2404IPW support true rail-to-rail input at 2.5 V supply?
Yes, TLV2404IPW supports rail-to-rail input operation down to 2.5 V supply, with common-mode range from –0.1 V to VCC + 5 V. At 2.5 V, this means inputs can go from –0.1 V to +7.5 V - verified across the full –40°C to 125°C temperature range. Input bias current increases above VCC but remains within datasheet limits.
Can TLV2404IPW drive capacitive loads without oscillation?
TLV2404IPW is stable driving capacitive loads up to 100 pF, as confirmed by phase margin ≥60° and gain margin ≥15 dB in the datasheet. For loads >100 pF, external isolation resistor (e.g., 100 Ω in series with output) is recommended. The device does not require external compensation for standard sensor buffering or filter applications.
What is the input offset voltage drift over temperature for TLV2404IPW?
The TLV2404IPW exhibits an input offset voltage drift of 3 µV/°C maximum, measured across the full industrial temperature range (–40°C to 125°C). This low drift ensures stable DC accuracy in precision temperature measurement circuits where ambient variations exceed 100°C, such as in automotive under-hood applications.
Is TLV2404IPW pin-compatible with other quad op-amps in TSSOP-14?
No, TLV2404IPW has a unique pinout optimized for quad-channel independence and reverse-battery protection - it is not pin-compatible with generic TSSOP-14 op-amps like LM324 or TLC274. The pin mapping (e.g., dual VCC pins, interleaved inputs/outputs) is specific to the TLV240x family and must be verified against the official TI datasheet SLOS244B before PCB layout.
