Product details
Overview
TLV2462QDGKRQ1 from Texas Instruments is a dual-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown capability, designed for HEV/EV battery management and lighting modules. It delivers 6.4 MHz gain bandwidth, 1.6 V/μs slew rate, ±80-mA output drive, 500 μA/channel supply current, and operates from 2.7 V to 6 V across –40°C to +125°C.
For engineers reviewing the TLV2462QDGKRQ1 datasheet, TLV2462QDGKRQ1 pinout, TLV2462QDGKRQ1 application, or TLV2462QDGKRQ1 equivalent, key selection criteria include rail-to-rail dynamic range in low-voltage systems, ultra-low shutdown current (0.3 μA/channel), AEC-Q100 Grade 1 qualification, and verified performance in DC-DC inverter feedback and analog sensor buffering.
Technical Context
The TLV2462QDGKRQ1 implements a dual-channel CMOS op-amp architecture with independent input stages extending beyond supply rails and rail-to-rail output swing. Its internal design supports stable operation with capacitive loads up to 160 pF while maintaining ≥44° phase margin at unity gain.
It features a dedicated shutdown terminal per channel (SHDN pin), enabling independent channel disable with high-impedance output state and sub-μA quiescent current. The device is optimized for single-supply operation in safety-critical automotive subsystems requiring low-noise (11 nV/√Hz), low-offset (150 μV typ), and robust ESD immunity (HBM ±2000 V, CDM ±1000 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - Enables stable closed-loop operation up to ~1 MHz with moderate gain in sensor signal conditioning. |
| Slew Rate | 1.6 V/μs - Supports fast transient response in motor control feedback and PWM-based lighting dimming circuits. |
| Supply Current / Channel | 500 μA - Allows continuous operation in always-on vehicle modules without excessive battery drain. |
| Output Drive Capability | ±80 mA - Directly drives ADC reference buffers, LED drivers, or small solenoids without external boost stages. |
| Rail-to-Rail I/O | Input extends to –0.2 V / VDD+0.2 V; output swings within 100 mV of rails - Maximizes dynamic range in 3.3 V or 5 V automotive systems. |
| Shutdown Current / Channel | 0.3 μA - Reduces system standby power in telematics or cluster modules during sleep mode. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - Preserves SNR in precision current sensing and battery cell voltage monitoring. |
Pinout & Package
The TLV2462QDGKRQ1 is packaged in an 8-pin VSSOP (DGK) with body size 3.00 mm × 3.00 mm, optimized for space-constrained automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input, channel 1 | Accepts feedback or inverted signal path for standard op-amp configurations (e.g., inverting amplifier, transimpedance). |
| 2 | Noninverting input, channel 1 | Reference or sensor input node; common-mode range extends beyond rails for direct connection to resistive dividers. |
| 3 | Output, channel 1 | Delivers rail-to-rail buffered signal; high-impedance when SHDN = low (channel disabled). |
| 4 | GND | System ground reference; must be low-impedance return path for both channels and shutdown logic. |
| 5 | Shutdown (SHDN) | Active-low enable: <0.7 V disables channel 1; >2 V enables. Independent of channel 2 control. |
| 6 | Positive supply (VDD+) | Single-supply input (2.7–6 V); powers both amplifiers and shutdown circuitry. |
| 7 | Inverting input, channel 2 | Second independent signal path; identical electrical specs to channel 1 for matched dual-sensing applications. |
| 8 | Noninverting input, channel 2 | Enables differential pair configuration or separate sensor inputs (e.g., temperature + voltage monitoring). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation in powertrain and body electronics. |
| Rail-to-rail output swing | Delivers full-scale signal to 12-bit+ ADCs without level-shifting, reducing BOM count in battery monitors. |
| Independent channel shutdown | Permits dynamic power gating in multi-function ECUs-e.g., disable channel 1 during CAN idle, retain channel 2 for wake-up detection. |
| High-output-drive capability | Drives 10-kΩ loads to rail with <0.2 V drop at 10 mA, eliminating need for external buffers in lighting driver interfaces. |
| Low input offset voltage | 150 μV typical (TLV2462A-Q1 variant) enables accurate current shunt amplification without trimming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CDR | Commercial-grade (–40°C to +125°C), no AEC-Q100 qualification; same pinout and electrical specs. | Not approved for automotive safety-critical functions; suitable for non-automotive industrial or consumer use. | Select only if AEC-Q100 compliance is not required and cost sensitivity outweighs qualification needs. |
| LMV358QDRQ1 | Lower GBW (1 MHz), lower output drive (40 mA), no shutdown function; AEC-Q100 Grade 1 qualified. | Limited to low-bandwidth sensor interfaces; cannot replace TLV2462QDGKRQ1 in high-speed or high-drive applications. | Choose when budget constraints dominate and system bandwidth <200 kHz suffices. |
Compared with TLV2462CDR and LMV358QDRQ1, the TLV2462QDGKRQ1 uniquely combines automotive qualification, shutdown capability, and high output drive-making it irreplaceable in active battery balancing and adaptive lighting where power gating and dynamic range are mandatory.

FAQ
What is the operating temperature range for TLV2462QDGKRQ1?
The TLV2462QDGKRQ1 is qualified for automotive Grade 1 operation, with a guaranteed ambient operating temperature range of –40°C to +125°C. This specification is validated per AEC-Q100 standards and applies across all electrical parameters in the datasheet, making TLV2462QDGKRQ1 suitable for engine bay and under-hood applications where thermal stress is critical.
Does TLV2462QDGKRQ1 support true rail-to-rail input and output?
Yes, TLV2462QDGKRQ1 supports rail-to-rail input common-mode voltage range (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing (within 100 mV of rails at 10 mA load). This enables direct interfacing with 3.3 V or 5 V microcontrollers and ADCs without external level-shifting, preserving signal fidelity in low-voltage automotive systems.
How does the shutdown feature work on TLV2462QDGKRQ1?
The TLV2462QDGKRQ1 has a dedicated SHDN pin (Pin 5) that controls channel 1 only. When pulled below 0.7 V, channel 1 enters ultra-low-power shutdown (0.3 μA/channel), and its output goes high-impedance. Channel 2 remains fully operational. This allows selective power gating-e.g., disabling one amplifier during sleep while retaining sensor wake-up capability via the second channel.
What package type is used for TLV2462QDGKRQ1?
TLV2462QDGKRQ1 uses the DGK package: an 8-pin VSSOP with nominal body dimensions of 3.00 mm × 3.00 mm and 0.5-mm lead pitch. This compact, surface-mount package supports high-density automotive PCB layouts and provides thermal performance characterized at RθJA = 179.3°C/W (JEDEC standard board).
Is TLV2462QDGKRQ1 pin-compatible with other TLV246x-Q1 variants?
TLV2462QDGKRQ1 shares the same 8-pin VSSOP (DGK) pinout with TLV2462A-Q1 in DGK package, but differs from SOIC (D) and TSSOP (PW) variants which have identical pin functions but different mechanical footprints. It is not pin-compatible with single-channel (TLV2461-Q1) or quad-channel (TLV2464A-Q1) members of the family due to differing pin counts and assignments.
