Product details
Overview
TLV2462AQD from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier designed for automotive and industrial signal conditioning. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage across −40°C to 125°C. It buffers analog-to-digital converters in engine control units and battery monitoring systems.
For engineers reviewing the TLV2462AQD datasheet, TLV2462AQD pinout, TLV2462AQD application, or TLV2462AQD equivalent, this page provides verified electrical specs, Q-temp automotive qualification details, shutdown behavior, thermal derating data, and real-world use cases in high-reliability analog front-ends.
Technical Context
The TLV2462AQD integrates two independent amplifiers with rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing, enabling full dynamic range operation from 2.7 V to 6 V single supply. Its internal architecture supports stable unity-gain operation with ≥44° phase margin into 160 pF capacitive loads.
Each channel features an active-low shutdown terminal (SHDN), reducing supply current to 0.3 µA per channel while placing the output in high-impedance state. The device is qualified to AEC-Q100 Grade 1 (−40°C to 125°C) and meets automotive configuration control requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - Enables stable closed-loop operation up to ~1 MHz at unity gain with minimal phase loss. |
| Slew Rate | 1.6 V/µs - Supports 10-bit ADC buffering at 100 kSPS without distortion in 3.3 V systems. |
| Input Offset Voltage | 100 µV (typ) - Ensures ≤0.002% gain error in precision sensor signal chains at room temperature. |
| Supply Current / Channel | 500 µA - Allows dual-opamp operation within 1 mA total budget for low-power automotive modules. |
| Output Drive | ±80 mA - Drives 37.5 Ω loads directly (e.g., 75 Ω coax with termination) without external buffers. |
| Shutdown Current | 0.3 µA/channel - Reduces system standby power by >99.9% versus active mode in duty-cycled sensors. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - Maintains SNR > 86 dB for 20 kHz audio-band signals with 10 kΩ source impedance. |
Pinout & Package
TLV2462AQD is packaged in an 8-pin SOIC (D package) with exposed pad, rated for −40°C to 125°C operation and qualified for automotive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Full rail-to-rail swing (0 V to VDD); capable of sourcing/sinking ±80 mA. |
| 2 (IN− A) | Channel A inverting input | High-impedance node (10⁹ Ω differential resistance); accepts rail-to-rail common-mode inputs. |
| 3 (IN+ A) | Channel A non-inverting input | Same CMVR as IN−; enables true single-supply instrumentation amplifier configurations. |
| 4 (GND) | Analog ground reference | Primary return path for both channels; must be low-impedance to minimize PSRR degradation. |
| 5 (IN+ B) | Channel B non-inverting input | Independent of Channel A; supports dual-sensor simultaneous sampling architectures. |
| 6 (IN− B) | Channel B inverting input | Matches IN− A performance; allows matched feedback networks for differential gain stages. |
| 7 (OUT B) | Channel B output | Electrically identical to OUT A; supports independent load driving or paralleled outputs. |
| 8 (VDD+) | Positive supply rail | Accepts 2.7–6 V; internal regulation ensures consistent biasing across temperature and supply variation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full-scale signal capture from 0 V to VDD in single-supply 3.3 V or 5 V systems without level-shifting. |
| Automotive Q-temp qualification | Qualified per AEC-Q100 Grade 1 with configuration control, extended temperature testing, and PPAP support. |
| Low-power shutdown mode | Reduces IDD to 0.3 µA/channel with output high-Z-critical for wake-on-event sensor nodes in body control modules. |
| High output drive | ±80 mA capability eliminates need for external buffer stages when driving ADC reference buffers or DAC loads. |
| Low input offset drift | 2 µV/°C max tempco ensures <150 µV total offset shift over −40°C to 125°C-vital for uncalibrated temperature sensing. |
Applications
| Engine Control Unit (ECU) Sensor Interface | Battery Management System (BMS) Cell Monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462QD | Same pinout and specs but rated only for −40°C to 125°C without AEC-Q100 qualification or configuration control. | Lacks automotive documentation package (PPAP, change notifications) and long-term supply assurance. | Select TLV2462QD only for non-automotive industrial designs where qualification overhead is unnecessary. |
| OPA2340UA | Higher 5.5 MHz GBW, lower 4.5 nV/√Hz noise, but no shutdown function and only 25 mA output drive. | Not qualified for automotive use; limited output current restricts direct ADC driving in high-impedance paths. | Choose OPA2340UA when ultra-low noise dominates over power savings and output strength in test equipment or medical devices. |
Compared with TLV2462QD, TLV2462AQD adds formal automotive qualification and lifecycle management; compared with OPA2340UA, it trades noise performance for integrated shutdown and robust output drive-making it optimal for cost-sensitive, power-constrained automotive analog front-ends.

FAQ
What is the operating temperature range for TLV2462AQD?
The TLV2462AQD is specified for continuous operation from −40°C to +125°C ambient temperature. This range satisfies AEC-Q100 Grade 1 requirements and is validated across all electrical parameters in the official TI datasheet SLOS220J. Thermal derating begins above 25°C per the dissipation rating table, with power limits adjusted using the 5.4 mW/°C factor for SOIC packages.
Does TLV2462AQD include a shutdown feature?
Yes, TLV2462AQD includes an active-low shutdown terminal (pin 5 on SOIC D package). When pulled below 0.7 V relative to GND, each amplifier channel enters ultralow-power mode drawing just 0.3 µA per channel while forcing its output into high-impedance state. This functionality is fully documented in the Electrical Characteristics table under IDD(SHDN) parameter.
What package type is used for TLV2462AQD?
TLV2462AQD is supplied in an 8-pin SOIC (D package) with exposed thermal pad, as confirmed in the "TLV2462M/AM/Q/AQ AVAILABLE OPTIONS" table on page 3 of the SLOS220J datasheet. This package supports surface-mount assembly and provides enhanced thermal performance for automotive under-hood applications.
How does TLV2462AQD compare to standard TLV2462 variants in terms of qualification?
TLV2462AQD differs from commercial TLV2462 variants by including full AEC-Q100 Grade 1 qualification, automotive configuration control, PPAP documentation support, and extended reliability testing. The "Q" suffix denotes automotive grade, while "A" indicates improved initial offset (1500 µV max vs. 2000 µV for non-A versions), making TLV2462AQD suitable for safety-critical automotive subsystems.
Can TLV2462AQD drive capacitive loads without oscillation?
Yes, TLV2462AQD maintains stability into ≥160 pF capacitive loads at unity gain, as verified by phase margin measurements of ≥44° in the Operating Characteristics section. The datasheet confirms stable operation with CL = 160 pF and RL = 10 kΩ, supporting direct connection to ADC input capacitors and long PCB traces without added isolation resistors.
