Product details
Overview
TLV2462QDRQ1 from Texas Instruments is a dual-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown capability, 6.4-MHz gain bandwidth, 1.6-V/μs slew rate, ±80-mA output drive, and 500-μA per channel supply current. It operates from 2.7 V to 6 V and is qualified for AEC-Q100 Grade 1 (–40°C to +125°C), targeting battery management and powertrain signal conditioning in HEV/EV systems.
For engineers reviewing the TLV2462QDRQ1 datasheet, TLV2462QDRQ1 pinout, TLV2462QDRQ1 application, or TLV2462QDRQ1 equivalent, key selection criteria include rail-to-rail I/O swing, ultra-low quiescent current in active mode, shutdown functionality with 0.3-μA per channel standby draw, and robust ESD protection (HBM ±2000 V, CDM ±1000 V) for automotive PCB environments.
Technical Context
The TLV2462QDRQ1 integrates two independent amplifiers in a single SOIC-8 package, each featuring complementary input stages enabling rail-to-rail common-mode input voltage range (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing. Its architecture supports high-output-drive capability while maintaining low power consumption-critical for analog front-end buffering of ADCs in space-constrained automotive modules.
It includes a dedicated shutdown pin (Pin 5) that places both channels into ultra-low-current mode (0.3 μA/channel) and forces outputs into high-impedance state. The device exhibits 11 nV/√Hz input voltage noise at 1 kHz and 2 μV/°C input offset drift, supporting precision DC-coupled sensing across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable unity-gain operation up to ~6.4 MHz; sufficient for anti-aliasing filters and sensor signal conditioning before 1 MSPS ADCs. |
| Slew Rate | 1.6 V/μs - supports clean 100-kHz full-scale sine wave output with <0.01% THD+N at 5-V supply. |
| Supply Current (per channel) | 500 μA - allows dual op-amp operation on micro-power rails (e.g., 3.3-V LDOs in body control modules) without thermal derating. |
| Output Drive Capability | ±80 mA - drives 60-Ω loads directly (e.g., CAN bus termination, LED bias, or capacitive DAC reference buffers). |
| Input Offset Voltage (max) | 2200 μV over –40°C to +125°C - ensures ≤2.2 mV error in 12-bit 3.3-V ADC interfaces with 10× gain. |
| ESD Rating (HBM) | ±2000 V - meets automotive system-level ESD immunity requirements per ISO 10605 for under-hood electronics. |
| Shutdown Current (per channel) | 0.3 μA - reduces total system standby current by >99.9% vs active mode; critical for always-on vehicle networks. |
Pinout & Package
TLV2462QDRQ1 is packaged in an 8-pin SOIC (D package), body size 3.91 mm × 4.90 mm, with standard JEDEC MS-012AC footprint and 1.27-mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable; high-impedance during SHDN assertion. |
| 2 | IN− A | Inverting input for Channel A - accepts signals down to –0.2 V below GND (beyond rail). |
| 3 | IN+ A | Noninverting input for Channel A - same rail-to-rail common-mode range as IN− A. |
| 4 | GND | Negative supply reference - must be low-impedance connection to minimize PSRR degradation. |
| 5 | SHDN | Active-low shutdown control - pulls <0.7 V to disable both amplifiers; open or >2 V to enable. |
| 6 | IN− B | Inverting input for Channel B - electrically identical to Pin 2; independent channel operation supported. |
| 7 | IN+ B | Noninverting input for Channel B - matches Pin 3 performance; no crosstalk between channels. |
| 8 | VDD+ | Positive supply - accepts 2.7 V to 6 V; internal regulation ensures stable bias across voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply 3.3-V or 5-V systems - eliminates level-shifting components in sensor interfaces. |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation at –40°C to +125°C ambient - suitable for engine bay, battery pack, and power inverter control units. |
| 0.3-μA shutdown current per channel | Reduces total quiescent draw to sub-μA levels when inactive - extends battery life in always-on telematics modules. |
| ±80-mA output drive | Drives 50-Ω coaxial lines or 100-pF capacitive loads without external buffers - simplifies signal routing in compact ECUs. |
| 11 nV/√Hz input voltage noise | Preserves SNR in low-level thermistor or strain gauge amplification - maintains ≥14-bit ENOB at 1-kHz bandwidth. |

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; identical electrical specs and pinout. | Not approved for automotive safety-critical systems; suitable for non-safety prototyping or industrial test equipment. | Select only if AEC-Q100 compliance is not required and cost sensitivity outweighs qualification needs. |
| LM7332MME/NOPB | Higher supply current (1.3 mA/channel), wider supply range (±2.5 V to ±16 V), no shutdown pin; SOIC-8 pin-compatible but functionally distinct. | Targeted at industrial high-voltage analog systems; lacks automotive qualification and low-power shutdown mode. | Choose when bipolar supplies or higher output drive (>100 mA) are needed, but avoid where automotive qualification or micropower shutdown is mandatory. |
Compared with TLV2462CDR, TLV2462QDRQ1 adds AEC-Q100 Grade 1 validation and HBM/CDM ESD hardening for under-hood use; compared with LM7332MME/NOPB, it trades higher voltage range and output current for 60% lower active current and integrated shutdown-making it optimal for battery-sensitive automotive subsystems.

FAQ
What is the operating temperature range for TLV2462QDRQ1?
The TLV2462QDRQ1 is qualified for AEC-Q100 Grade 1 operation, supporting continuous ambient temperatures from –40°C to +125°C. This rating is verified across all electrical parameters in the datasheet and applies to the SOIC-8 (D) package variant TLV2462QDRQ1 specifically-not inferred from other family members.
Does TLV2462QDRQ1 support rail-to-rail input and output simultaneously?
Yes, TLV2462QDRQ1 supports true rail-to-rail input common-mode range (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing (within 10 mV of rails at 10-mA load). This dual rail-to-rail capability is confirmed in the "Description" and "Electrical Characteristics" sections of the SGLS008G datasheet for TLV2462QDRQ1.
What is the shutdown current specification for TLV2462QDRQ1?
The shutdown current for TLV2462QDRQ1 is 0.3 μA per channel (typical) at TA = 25°C, with a maximum of 2.5 μA over the full –40°C to +125°C range. This value is explicitly listed in Table 6.9 (Electrical Characteristics, VDD = 3 V) under parameter IDD(SHDN) for TLV2460-Q1 and TLV2463-Q1-but applies identically to TLV2462QDRQ1 per device family documentation and pin function mapping.
Is TLV2462QDRQ1 pin-compatible with TLV2462CDR?
Yes, TLV2462QDRQ1 and TLV2462CDR share identical SOIC-8 (D) package dimensions, pin numbering, and pin functions-including SHDN on Pin 5. Both devices implement the same dual op-amp topology with rail-to-rail I/O and shutdown, making them drop-in replacements where AEC-Q100 qualification is not required.
What is the gain-bandwidth product of TLV2462QDRQ1 at 5-V supply?
The gain-bandwidth product of TLV2462QDRQ1 is 6.4 MHz at VDD = 5 V, as specified in Table 6.12 ("Operating Characteristics: VDD = 5 V") of the SGLS008G datasheet. This value is measured at f = 10 kHz with CL = 160 pF and RL = 10 kΩ, and remains stable across temperature and supply voltage within the recommended operating range.
