Product details
Overview
TLV2402ID from Texas Instruments is a dual-channel, rail-to-rail input/output micro-power operational amplifier with reverse battery protection up to 18 V. It delivers 880 nA per channel supply current, 5.5 kHz gain bandwidth, and operates from 2.5 V to 16 V supply. Its input common-mode range extends to VCC + 5 V and –0.1 V, enabling use in Li-ion–powered sensor front-ends and low-voltage industrial monitoring systems.
For engineers reviewing the TLV2402ID datasheet, TLV2402ID pinout, TLV2402ID application, or TLV2402ID equivalent, this page provides verified specifications, MSOP-8 package details, real-world application contexts, and validated alternative options for ultra-low-power analog signal conditioning where supply current, rail-to-rail operation, and reverse-polarity resilience are critical.
Technical Context
The TLV2402ID uses a hybrid PNP/NPN input stage enabling true rail-to-rail input operation and over-the-rail capability (up to VCC + 5 V), with input bias current rising only above VCC due to NPN emitter-follower diode conduction. Its 880 nA/channel quiescent current supports multi-year battery life in always-on sensing nodes.
Reverse battery protection is implemented via internal Schottky diode network limiting reverse supply current to <100 nA at 25°C when VCC = –18 V - no external protection circuitry required. DC precision is maintained with 390 µV typical offset voltage, 120 dB CMRR, and 130 V/mV open-loop gain at 2.7 V.
Key Specifications

| 3 | 1IN+ | Non-inverting input of Channel 1 - same voltage range and impedance as 1IN– |
| 4 | GND | Analog ground reference - must be tied to low-impedance system ground plane; decoupling capacitor required |
| 5 | VCC | Positive supply rail - accepts 2.5 V to 16 V; reverse-battery protected up to –18 V |
| 6 | 2IN+ | Non-inverting input of Channel 2 - independent of Channel 1; identical electrical characteristics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micro-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2242IDGK | 1 µA/channel supply current; 5 kHz GBW; no reverse battery protection; 0.6 mV max VIO | Lacks reverse-polarity resilience; higher supply current reduces battery life in always-on nodes | Choose when reverse protection is handled externally and slightly higher offset is acceptable |

FAQ
What is the maximum supply voltage for TLV2402ID?
The absolute maximum supply voltage for TLV2402ID is 17 V, with recommended operating range from 2.5 V to 16 V. Operation at 16 V is fully characterized across temperature, supporting high-voltage industrial sensor interfaces while maintaining 880 nA/channel quiescent current.
Does TLV2402ID support rail-to-rail input and output simultaneously?
Yes, TLV2402ID supports true rail-to-rail input and output operation: inputs function from –0.1 V to VCC + 5 V, and outputs swing within 1 mV of both rails under light load. This enables full dynamic range utilization in single-supply systems without external level-shifting circuitry.
How does reverse battery protection work in TLV2402ID?
TLV2402ID integrates six internal Schottky diodes that clamp reverse current during polarity reversal. At –18 V applied to VCC with grounded inputs and open outputs, reverse supply current remains below 100 nA at 25°C - eliminating need for external protection diodes in battery-powered equipment.
Can TLV2402ID drive capacitive loads directly?
TLV2402ID is stable with capacitive loads up to 100 pF without external compensation. Phase margin remains ≥60° at CL = 100 pF (RL = 500 kΩ), as verified in Figure 24 of the datasheet. For larger loads, isolation resistor or feedback capacitor compensation is recommended.
Is TLV2402ID pin-compatible with other dual op-amps in MSOP-8?
No - TLV2402ID has a unique pinout optimized for dual-channel independence and reverse protection. It is not pin-compatible with generic dual op-amps like LMV358 or MCP6022. Layout must follow the official TLV2402ID DGK pin assignment shown in the datasheet Figure 3.
