Product details
Overview
TLV2402QDGKRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 qualified, rail-to-rail input/output operational amplifier with nano-power operation (880 nA/channel), reverse battery protection up to 18 V, and wide supply range (2.5 V to 16 V). It delivers 390 µV typical offset voltage, 120 dB CMRR, and 5.5 kHz gain-bandwidth product - designed for high-voltage, ultra-low-power monitoring in automotive electric powertrain systems.
For engineers reviewing the TLV2402QDGKRQ1 datasheet, TLV2402QDGKRQ1 pinout, TLV2402QDGKRQ1 application, or TLV2402QDGKRQ1 equivalent, key selection considerations include its 8-pin VSSOP package, –40°C to 125°C operating range, reverse-battery-protected input stage, rail-to-rail output swing into 500 kΩ, and compatibility with Li-ion battery-powered microcontrollers such as MSP430/MSP432.
Technical Context
The TLV2402QDGKRQ1 employs a hybrid PNP/NPN input stage enabling rail-to-rail input operation plus 5 V beyond VCC without damage, while maintaining low input bias current (±100 pA typ). Its internal architecture includes Schottky diode-based reverse-battery protection limiting supply current to <100 nA under –18 V supply stress.
DC precision is achieved via laser-trimmed input offset (390 µV typ), high open-loop gain (≥102 dB at 2.7 V), and robust PSRR (±10 µV/V at 5 V). The amplifier operates stably with capacitive loads up to 100 pF and maintains ≥60° phase margin across 2.7–15 V supply and –40°C to 125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 16 V - supports single-supply Li-ion (2.7–4.2 V) and 12 V automotive systems without level-shifting. |
| Quiescent Current | 880 nA/channel - enables multi-year battery life in always-on vehicle monitoring circuits. |
| Input Offset Voltage | 390 µV (typ) - ensures sub-mV DC accuracy in high-gain sensor signal conditioning (e.g., current shunt amplification). |
| CMRR | 120 dB (typ) - rejects common-mode noise from noisy 12 V/48 V bus environments in EV inverters and OBCs. |
| Gain-Bandwidth Product | 5.5 kHz - suitable for DC-coupled, low-frequency signal processing (e.g., battery cell voltage monitoring, temperature sensing). |
| Input Common-Mode Range | –0.1 V to VCC + 5 V - allows direct connection to battery terminals exceeding supply rails, critical for reverse-polarity fault tolerance. |
| Reverse Battery Protection | Withstands –18 V supply - eliminates need for external series diodes or protection ICs in automotive battery-sensed circuits. |
Pinout & Package
TLV2402QDGKRQ1 is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm, optimized for space-constrained automotive PCB layouts and thermally efficient mounting on small copper pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 (Pin 1) | Output, Channel 1 | Rail-to-rail output capable of sourcing/sinking ±200 µA; drives high-impedance nodes directly without buffering. |
| IN1– (Pin 2) | Inverting Input, Channel 1 | High-impedance node (300 MΩ differential resistance); accepts signals up to VCC + 5 V with no damage. |
| IN1+ (Pin 3) | Noninverting Input, Channel 1 | Same voltage range and impedance as IN1–; used for precision differential or single-ended sensing. |
| V– (Pin 4) | Negative Supply / Ground | Reference terminal for single-supply operation; must be connected to system ground or negative rail. |
| IN2+ (Pin 5) | Noninverting Input, Channel 2 | Independent second channel input; enables dual-sensor monitoring (e.g., voltage + temperature) in one package. |
| IN2– (Pin 6) | Inverting Input, Channel 2 | Matches IN1– specs; supports matched dual-channel configurations like instrumentation amp front-ends. |
| OUT2 (Pin 7) | Output, Channel 2 | Functionally identical to OUT1; allows independent signal paths without crosstalk degradation (–60 dB @ 1 kHz). |
| V+ (Pin 8) | Positive Supply | Accepts 2.5–16 V; reverse-battery protected - safe during jump-start or battery replacement events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2402IDGKR | Non-automotive grade (–40°C to 125°C not AEC-Q100 certified); identical electrical specs and pinout. | Lacks automotive qualification - unsuitable for safety-critical powertrain functions but acceptable for infotainment or body electronics. | Select TLV2402IDGKR only for non-AEC-Q100 designs where cost sensitivity outweighs qualification requirements. |
| LPV821DRXT | Lower supply current (650 nA/channel), but narrower supply range (1.6–5.5 V) and no reverse-battery protection. | Restricted to low-voltage battery systems (e.g., 3.3 V MCU domains); cannot interface directly with 12 V/48 V buses. | Choose LPV821DRXT only for ultra-low-power sub-5 V subsystems where rail extension and reverse protection are unnecessary. |
Compared with TLV2402IDGKR, TLV2402QDGKRQ1 adds AEC-Q100 qualification and production traceability for automotive use; compared with LPV821DRXT, it trades 230 nA higher IQ for 10.5 V wider supply range and integrated reverse-battery hardening - essential for under-hood deployment.

FAQ
What is the maximum supply voltage rating for TLV2402QDGKRQ1?
The absolute maximum supply voltage for TLV2402QDGKRQ1 is 17 V, with recommended operation up to 16 V. Exceeding 16 V risks parametric degradation, though the device survives brief transients per AEC-Q100 stress testing. Electrical characteristics are fully specified from 2.5 V to 16 V, including performance at 2.7 V, 5 V, and 15 V nominal rails.
Does TLV2402QDGKRQ1 support true rail-to-rail input operation?
Yes, TLV2402QDGKRQ1 supports rail-to-rail input operation from –0.1 V to VCC + 5 V. This is achieved via a hybrid PNP/NPN input stage that remains functional even when inputs exceed the positive supply rail by up to 5 V - a key enabler for direct battery terminal sensing without external level-shifting components.
How does reverse battery protection work in TLV2402QDGKRQ1?
TLV2402QDGKRQ1 integrates six internal Schottky diodes to limit reverse supply current to <100 nA at –18 V and 25°C. Under reverse polarity, the diodes block conduction while leakage remains nanoamp-level - preventing latch-up, thermal runaway, or permanent damage during improper battery installation in automotive service environments.
What is the typical input offset voltage drift over temperature for TLV2402QDGKRQ1?
The typical input offset voltage drift for TLV2402QDGKRQ1 is ±3 µV/°C across –40°C to 125°C. This low drift, combined with 390 µV typical initial offset, ensures stable DC accuracy in engine bay or powertrain locations where ambient temperature swings exceed 100°C - critical for reliable battery voltage monitoring over vehicle lifetime.
Can TLV2402QDGKRQ1 drive capacitive loads, and what is the stability limit?
Yes, TLV2402QDGKRQ1 is stable driving capacitive loads up to 100 pF with ≥60° phase margin and ≥15 dB gain margin. Stability is verified across 2.7–15 V supply and –40°C to 125°C ambient. For loads >100 pF, external isolation resistance (e.g., 10 Ω in series with output) is recommended to maintain phase margin above 45°.
