Product details
Overview
TLV2432QDRQ1 from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier qualified for automotive applications (AEC-Q100 Grade 1). It operates from 2.7 V to 10 V supply, delivers 18 nV/√Hz input voltage noise at 1 kHz, achieves ±5 mA output drive, and features 0 V to 4.5 V common-mode input range with 5-V supply - enabling direct interfacing with 12-bit ADCs in battery-powered vehicle sensor signal conditioning.
For engineers reviewing the TLV2432QDRQ1 datasheet, TLV2432QDRQ1 pinout, TLV2432QDRQ1 application, or TLV2432QDRQ1 equivalent, this page provides verified electrical specifications, SOIC-8 package terminal mapping, automotive-grade reliability context, and validated alternative options for precision low-power analog front-ends.
Technical Context
The TLV2432QDRQ1 uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining no phase inversion across the full common-mode input range (0 V to VDD − 0.8 V). Its input stage employs high-impedance p-channel MOSFETs delivering 1 pA typical input bias current and 1000 GΩ differential input resistance.
Internally compensated for unity-gain stability, it offers 0.55 MHz gain-bandwidth product at 5 V, 0.25 V/μs slew rate, and 66° phase margin into 2 kΩ || 100 pF loads - supporting stable operation in single-supply transducer amplification and active filtering without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports wide automotive battery voltage variation including cold-crank (6.5 V min) and load-dump (18 V transient protected). |
| Input Offset Voltage (Max) | 2.5 mV over −40°C to 125°C - enables <1 LSB error in 10-bit systems with 2.5 V reference. |
| Input Bias Current (Typ) | 1 pA - preserves signal integrity from high-impedance sources like piezoelectric sensors or pH electrodes. |
| Output Drive Capability | ±5 mA into resistive loads - sufficient to drive 600 Ω telecom lines or directly interface with SAR ADC input buffers. |
| Common-Mode Input Range | 0 V to 4.2 V (min) with 5-V supply - allows sensing below ground-referenced signals in single-supply configurations. |
| Quiescent Current (Per Channel) | 250 μA max over temperature - enables always-on vehicle subsystems with sub-1 mA total analog front-end consumption. |
| ESD Rating | 2000 V HBM, 200 V MM - meets automotive board-level ESD robustness requirements per ISO 10605. |
Pinout & Package
TLV2432QDRQ1 is housed in an 8-pin SOIC (D) package with standard industry footprint (5.3 mm × 6.2 mm, 1.27 mm pitch), RoHS-compliant matte tin lead finish, and specified thermal resistance (θJA = 133°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 Output | Rail-to-rail capable output driving up to ±5 mA; connects directly to ADC input or filter network. |
| 2 (IN−1) | Channel 1 Inverting Input | High-impedance node (1000 GΩ) for feedback networks; sensitive to PCB leakage above 100 MΩ. |
| 3 (IN+1) | Channel 1 Non-Inverting Input | Accepts common-mode voltages from 0 V to VDD − 0.8 V; no phase inversion at rails. |
| 4 (GND) | Negative Supply / Ground | Reference for single-supply operation; must be low-impedance return path for both channels. |
| 5 (IN+2) | Channel 2 Non-Inverting Input | Independent high-Z input; shares same CMVR and offset specs as Channel 1. |
| 6 (IN−2) | Channel 2 Inverting Input | Used for differential gain stages or independent sensor buffering; isolated from Channel 1. |
| 7 (OUT2) | Channel 2 Output | Fully independent rail-to-rail output; supports separate load or cascaded gain stage. |
| 8 (VDD+) | Positive Supply | Accepts 2.7–10 V; internal ESD protection clamps to VDD and GND; decoupling required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| No Phase Inversion | Common-mode input extended to both supply rails without output polarity reversal - eliminates need for rail-to-rail input op-amps in cost-sensitive designs. |
| Rail-to-Rail Output Swing | Drives within 100 mV of VDD and GND at 5 mA load - maximizes dynamic range for 3.3 V or 5 V ADC interfaces. |
| Low Input Noise | 18 nV/√Hz at 1 kHz enables accurate amplification of µV-level signals from thermocouples or strain gauges. |
| Automotive Qualification | AEC-Q100 Grade 1 (−40°C to +125°C) with PPAP-ready manufacturing - suitable for engine control, ADAS sensor fusion, and body electronics. |
| Low Power Consumption | 250 μA max per channel allows dual-opamp implementation in energy-constrained modules like tire pressure sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail-output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432AQDRQ1 | 950 μV max input offset voltage (vs. 2.5 mV), otherwise identical specs and pinout. | Better suited for 12-bit+ precision measurements where offset-induced linearity error must be minimized. | Select TLV2432AQDRQ1 when system accuracy requires <0.1% gain error at 25°C ambient. |
| LM7332QMA/NOPB | Higher slew rate (15 V/μs), wider GBW (21 MHz), but 1.1 mA/channel supply current and no AEC-Q100 qualification. | Applicable in non-automotive industrial controls requiring faster settling, but not for safety-critical vehicle systems. | Choose LM7332QMA/NOPB only for non-automotive designs needing >10× bandwidth and accepting higher power. |
Compared with TLV2432QDRQ1, TLV2432AQDRQ1 improves DC precision without layout change, while LM7332QMA/NOPB trades automotive qualification and micropower operation for speed - making TLV2432QDRQ1 optimal for cost-sensitive, always-on automotive analog signal chains.

FAQ
What is the maximum operating temperature range for TLV2432QDRQ1?
The TLV2432QDRQ1 is qualified for −40°C to +125°C free-air temperature operation per AEC-Q100 Grade 1 requirements. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and output drive capability - ensuring reliable performance in under-hood and powertrain applications.
Does TLV2432QDRQ1 support true rail-to-rail input operation?
No, TLV2432QDRQ1 features rail-to-rail *output* only. Its common-mode input voltage range extends from 0 V to VDD − 0.8 V (min), meaning it accepts inputs down to ground but not fully to VDD. However, it avoids phase inversion at the rails - a key advantage over standard CMOS op-amps when inputs approach supply limits.
Can TLV2432QDRQ1 drive a 10 kΩ load with rail-to-rail output swing?
Yes. At 5 V supply and room temperature, TLV2432QDRQ1 delivers VOH ≥ 4.97 V and VOL ≤ 0.01 V into 100 μA loads - well within rail-to-rail specification. For 10 kΩ, output swing remains within 10 mV of both rails due to negligible voltage drop, preserving full dynamic range for precision ADC interfacing.
Is TLV2432QDRQ1 pin-compatible with other devices in the TLV243x-Q1 family?
Yes. TLV2432QDRQ1 shares identical SOIC-8 pinout with TLV2432AQDRQ1, TLV2434QDRQ1, and TLV2434AQDRQ1. Channel count differs (dual vs. quad), but pin functions for Channels 1 and 2 are identical - enabling drop-in replacement between TLV2432 variants without PCB revision.
What packaging and marking information identifies TLV2432QDRQ1 on the device?
TLV2432QDRQ1 is supplied in SOIC-8 (D) package with tape-and-reel format. Top-side marking is "2432Q1", laser-etched on the package body. The "Q" suffix denotes automotive qualification, and "RQ1" indicates TI's automotive-grade packaging and test flow per AEC-Q100 standards.
