Product details
Overview
TLV2404IDRG4 from Texas Instruments is a quad, rail-to-rail input/output operational amplifier optimized for ultra-low-power, single-supply operation in battery-powered and energy-constrained systems. It delivers 880 nA per channel supply current, ±10 mA output drive capability, reverse battery protection up to –18 V, and rail-to-rail I/O swing across a 2.5 V to 16 V supply range - enabling use in Li-ion sensor front-ends and portable medical monitors.
For engineers reviewing the TLV2404IDRG4 datasheet, TLV2404IDRG4 pinout, TLV2404IDRG4 application, or TLV2404IDRG4 equivalent, key selection criteria include its 5.5 kHz gain-bandwidth product, 390 µV typical input offset voltage, 120 dB CMRR, 130 V/mV open-loop gain at 2.7 V, and guaranteed operation from –40°C to 125°C industrial temperature range.
Technical Context
The TLV2404IDRG4 employs a dual-differential input stage (PNP + NPN emitter followers) to achieve rail-to-rail input operation with common-mode range extending 5 V beyond VCC and down to –0.1 V below ground. This architecture enables robust signal conditioning in mismatched supply environments without external level-shifting.
Its reverse battery protection relies on internal Schottky diode clamping, limiting reverse supply current to <100 nA at 25°C when VCC = –18 V - eliminating need for external series diodes in automotive or handheld battery interfaces. Output stage is designed for capacitive loads up to 100 pF with ≥60° phase margin.
Key Specifications

|---|---|
| Supply Current / Channel | 880 nA typical - enables >10-year battery life in always-on sensor nodes using CR2032 or coin cells. |
| Input Offset Voltage | 390 µV typical - supports high-precision DC-coupled amplification of µV-level thermocouple or strain gauge signals. |
| Gain Bandwidth Product | 5.5 kHz - suitable for low-frequency signal conditioning (ECG, pH, gas sensing) without stability risk. |
| Rail-to-Rail I/O | Input common-mode range: –0.1 V to VCC + 5 V; output swing within 180 mV of rails - maximizes dynamic range in 3.3 V or lower systems. |
| Reverse Battery Protection | Withstands –18 V reverse supply with <100 nA leakage - eliminates external protection diode in battery-reversal-prone applications. |

Pinout & Package
TLV2404IDRG4 is packaged in a 14-pin TSSOP (PW) with exposed pad, offering compact footprint and thermal performance suitable for space-constrained PCBs. Pinout follows standard quad op-amp configuration with independent inputs/outputs per channel and shared VCC/GND rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives load directly; rail-to-rail swing supports full utilization of supply headroom. |
| 2 | 1IN– | Inverting input of Channel 1 - high-impedance node; bias current ≤900 pA (max) minimizes error with megaohm feedback networks. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts signals from –0.1 V to VCC + 5 V, enabling overvoltage-tolerant sensor interfacing. |
| 4 | VCC | Positive supply rail - operates from 2.5 V to 16 V; reverse protection active when voltage is negative. |
| 5 | 2IN+ | Non-inverting input of Channel 2 - identical electrical characteristics to Pin 3; supports independent signal paths. |
| 6 | 2IN– | Inverting input of Channel 2 - matched to Pin 2; enables differential or instrumentation amplifier configurations. |
| 7 | 2OUT | Output of Channel 2 - fully independent; no crosstalk degradation above –40 dB at 1 kHz (typical). |
| 8 | GND | Ground reference - low-impedance return path; requires solid ground plane per layout guidelines. |
| 9 | 3OUT | Output of Channel 3 - supports multi-channel signal conditioning without external multiplexing. |
| 10 | 3IN– | Inverting input of Channel 3 - electrically identical to Pins 2 and 6; enables parallel processing of sensor arrays. |
| 11 | 3IN+ | Non-inverting input of Channel 3 - same extended common-mode range as Pins 3 and 5. |
| 12 | VCC | Positive supply rail (redundant connection) - improves supply current distribution and reduces IR drop in high-density layouts. |
| 13 | 4IN+ | Non-inverting input of Channel 4 - completes quad functionality; allows simultaneous monitoring of four analog channels. |
| 14 | 4IN– | Inverting input of Channel 4 - matched performance ensures consistent gain accuracy across all four channels. |

FAQ
What is the maximum supply voltage for TLV2404IDRG4?
The absolute maximum supply voltage for TLV2404IDRG4 is 17 V, but the recommended operating range is 2.5 V to 16 V. Operation at 16 V is fully characterized with specified parameters including 130 V/mV open-loop gain and 120 dB CMRR. Exceeding 17 V risks permanent damage per absolute maximum ratings.
Does TLV2404IDRG4 support true rail-to-rail input beyond the supply rails?
Yes - TLV2404IDRG4 supports input voltages from –0.1 V to VCC + 5 V. This overvoltage tolerance is achieved via an NPN/PNP composite input stage that transitions into diode conduction above VCC, allowing direct interface to sensors or transducers operating at higher potentials than the op-amp's own supply.
How does reverse battery protection work in TLV2404IDRG4?
TLV2404IDRG4 incorporates six internal Schottky diodes that clamp reverse supply current to <100 nA at –18 V and 25°C. This eliminates the need for external series diodes in battery-powered systems, preserving forward voltage headroom and reducing bill-of-materials cost while maintaining system-level fault resilience.
What is the typical input offset voltage of TLV2404IDRG4 and how does it vary with temperature?
TLV2404IDRG4 has a typical input offset voltage of 390 µV at 25°C, with a maximum of 1500 µV across the full –40°C to 125°C industrial range. Its offset drift is specified at 3 µV/°C, ensuring predictable DC error accumulation in precision temperature or strain measurement applications.
Can TLV2404IDRG4 drive capacitive loads, and what is the stability limit?
TLV2404IDRG4 is characterized for stable operation with capacitive loads up to 100 pF, maintaining ≥60° phase margin and ≥15 dB gain margin. For loads exceeding 100 pF, external isolation resistance (e.g., 10–100 Ω in series with output) is recommended to preserve stability in sensor cable or ADC input buffering applications.
