Product details
Overview
TLV2461AQDRG4Q1 from Texas Instruments is a single-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown functionality. It delivers 6.4 MHz gain-bandwidth, 1.6 V/μs slew rate, ±80-mA output drive, and 500 μA/channel supply current at 5 V, operating across –40°C to +125°C for battery management and lighting modules in HEV/EV powertrains.
For engineers reviewing the TLV2461AQDRG4Q1 datasheet, TLV2461AQDRG4Q1 pinout, TLV2461AQDRG4Q1 application, or TLV2461AQDRG4Q1 equivalent, key selection criteria include rail-to-rail dynamic range, ultra-low shutdown current (0.3 μA/channel), AEC-Q100 Grade 1 qualification, and TSSOP-8 packaging compatible with space-constrained automotive PCB layouts.
Technical Context
The TLV2461AQDRG4Q1 implements a CMOS-input, rail-to-rail output architecture enabling full-swing operation from 2.7 V to 6 V supplies. Its input common-mode range extends 0.2 V beyond both rails, supporting low-voltage sensor interfacing in battery monitoring systems.
Integrated shutdown control (SHDN pin) reduces quiescent current to 0.3 μA per channel while placing the output in high-impedance state-critical for power-gated subsystems in telematics and lighting control units where standby leakage must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - enables stable unity-gain buffer operation up to ~6 MHz with minimal phase margin degradation |
| Slew rate | 1.6 V/μs - supports clean 10-kHz, 2-VPP signal amplification without distortion in ADC driver stages |
| Output drive | ±80 mA - drives 10-kΩ loads to rail while maintaining linearity, suitable for driving analog multiplexers or LED bias circuits |
| Supply current | 500 μA/channel - enables multi-channel sensing nodes in BMS with sub-2-mA total system bias current |
| Input offset voltage | 150–2000 μV - ensures <0.1% error in 3.3-V sensor signal conditioning at room temperature |
| Shutdown current | 0.3 μA/channel - allows >10-year battery life in always-on vehicle modules during ignition-off states |
| Operating temperature | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and powertrain placement |
Pinout & Package
TLV2461AQDRG4Q1 is housed in an 8-pin TSSOP (PW) package measuring 4.40 mm × 3.00 mm, optimized for automated SMT assembly and thermal performance in automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - rail-to-rail swing supports direct interface to SAR ADC reference buffers or comparator inputs |
| 2 | IN− | Inverting input - accepts differential sensor signals or configured as unity-gain inverter with precision feedback network |
| 3 | IN+ | Noninverting input - wide common-mode range (–0.2 V to VDD+0.2 V) enables direct connection to shunt resistors or thermistor dividers |
| 4 | GND | Negative supply - serves as analog reference plane; requires dedicated low-impedance ground pour beneath package |
| 5 | NC | No internal connection - left unconnected; no routing or thermal pad required |
| 6 | SHDN | Active-low shutdown control - pulled low (<0.7 V) to enter 0.3-μA standby mode; high-Z output prevents loading downstream circuitry |
| 7 | VDD+ | Positive supply - accepts 2.7–6 V single supply; decoupling capacitor (100 nF) mandatory within 3 mm of pin |
| 8 | NC | No internal connection - electrically isolated; may be used as thermal relief pad if grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full 0–VDD signal swing on both input and output, maximizing dynamic range in 3.3-V or 5-V automotive systems |
| AEC-Q100 Grade 1 | Qualified for –40°C to +125°C ambient operation with HBM ESD ≥2000 V and CDM ≥1000 V-meets functional safety readiness for ASIL-B subsystems |
| Low-noise input | 11 nV/√Hz at 1 kHz permits accurate amplification of microvolt-level signals from current-sense shunts or NTC thermistors |
| High-output drive | ±80-mA sourcing/sinking capability eliminates need for external buffer stages when driving capacitive loads ≤100 pF |
| Ultra-low shutdown | 0.3 μA/channel shutdown current enables rapid power cycling in CAN/LIN wake-up architectures without compromising sleep-state integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461QDRQ1 | Standard version without 'A' grade; higher max input offset voltage (2000 μV vs. 1500 μV) | Acceptable for non-critical signal paths where offset trimming is performed digitally | Select when cost sensitivity outweighs need for tighter initial offset specification |
| LM7321QDRQ1 | Higher slew rate (20 V/μs), wider GBW (20 MHz), but 1.3 mA supply current and no shutdown | Suitable for high-speed loop control but incompatible with ultra-low-power sleep modes | Choose only when dynamic response dominates power budget constraints |
Compared with TLV2461QDRQ1, TLV2461AQDRG4Q1 offers tighter input offset and lower drift for precision sensing; versus LM7321QDRQ1, it trades bandwidth for 2.6× lower active current and integrated shutdown-making it optimal for duty-cycled automotive subsystems.

FAQ
What is the maximum supply voltage rating for TLV2461AQDRG4Q1?
The absolute maximum supply voltage for TLV2461AQDRG4Q1 is 6 V. Operation above this level risks permanent damage per Absolute Maximum Ratings (Section 6.1). Recommended operating range is 2.7 V to 6 V for single-supply use, ensuring reliable rail-to-rail performance and AEC-Q100 compliance across –40°C to +125°C.
Does TLV2461AQDRG4Q1 support true rail-to-rail input and output simultaneously?
Yes, TLV2461AQDRG4Q1 supports 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 each rail at ±80 mA). This dual rail-to-rail capability enables direct interfacing with 3.3-V or 5-V ADCs and sensors without level-shifting components in TLV2461AQDRG4Q1-based designs.
How does the shutdown function behave in TLV2461AQDRG4Q1?
When SHDN (Pin 6) is pulled low (<0.7 V), TLV2461AQDRG4Q1 enters ultra-low-power mode drawing 0.3 μA/channel, and its output transitions to high-impedance state. The amplifier resumes normal operation within 7.6 μs after SHDN returns high, making TLV2461AQDRG4Q1 suitable for periodic wake-up sensing in automotive microcontrollers.
Is TLV2461AQDRG4Q1 qualified for automotive safety-critical applications?
TLV2461AQDRG4Q1 is AEC-Q100 Grade 1 qualified (–40°C to +125°C), with HBM ESD ≥2000 V and CDM ESD ≥1000 V. While not ASIL-certified standalone, it is widely deployed in ASIL-B subsystems like battery monitoring and lighting control when integrated into properly architected safety mechanisms per ISO 26262.
What is the typical input bias current of TLV2461AQDRG4Q1 at 25°C and 5 V supply?
At 25°C and VDD = 5 V, TLV2461AQDRG4Q1 exhibits a typical input bias current of 1.3 nA (max 14 nA over full temperature range). This low bias current minimizes voltage errors in high-impedance sensor interfaces such as thermistor networks or photodiode transimpedance stages using TLV2461AQDRG4Q1.
