Product details
Overview
TLV2461QDRQ1 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 product, 1.6-V/μs slew rate, ±80-mA output drive, 500-μA supply current per channel, and 100-μV max input offset voltage at 25°C - enabling high-fidelity signal conditioning in HEV/EV battery management and lighting modules.
For engineers reviewing the TLV2461QDRQ1 datasheet, TLV2461QDRQ1 pinout, TLV2461QDRQ1 application, or TLV2461QDRQ1 equivalent, this page provides verified electrical specifications, TSSOP-8 package details, functional pin mapping, automotive-grade reliability data (AEC-Q100 Grade 1), and validated alternative options for low-power analog front-end design.
Technical Context
The TLV2461QDRQ1 implements a CMOS input stage with rail-to-rail input common-mode range extending beyond supply rails (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing delivering full dynamic range in 2.7-V to 6-V single-supply systems. Its micropower shutdown mode reduces supply current to 0.3 μA/channel while placing the output in high-impedance state.
Designed for automotive signal buffering and ADC driving, it features 11 nV/√Hz input voltage noise, 0.13 pA/√Hz input current noise, and stable operation with capacitive loads up to 160 pF - confirmed by 45° phase margin and 7-dB gain margin at unity gain with 10-kΩ load and 160-pF capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - supports stable closed-loop operation up to ~1 MHz with moderate gain in sensor interface circuits. |
| Slew rate | 1.6 V/μs - enables accurate reproduction of 100-kHz, 1-VPP signals without distortion in active filters. |
| Input offset voltage | 100 μV (max at 25°C) - ensures ≤0.5% error in 200-mV full-scale current-sense applications. |
| Supply current per channel | 500 μA - allows continuous operation for >1 year on a 220-mAh coin cell in always-on monitoring nodes. |
| Output drive capability | ±80 mA - directly drives 50-Ω transmission lines or 10-kΩ ADC input networks without external buffers. |
| Rail-to-rail I/O | Input range: –0.2 V to VDD + 0.2 V; Output swing: within 10 mV of rails - maximizes SNR in low-voltage battery-powered systems. |
| Shutdown current | 0.3 μA - reduces system standby power to sub-μW levels when amplification is inactive. |
Pinout & Package
TLV2461QDRQ1 is housed in an 8-pin TSSOP (PW) package measuring 4.40 mm × 3.00 mm, optimized for space-constrained automotive PCB layouts and compatible with standard surface-mount reflow profiles.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461AQPWRQ1 | Lower input offset voltage (150 μV max vs. 200 μV max over full temperature range); same pinout and specs otherwise. | Better DC accuracy required in precision voltage reference buffers or high-gain transimpedance stages. | Select TLV2461AQPWRQ1 when <150-μV offset across –40°C to +125°C is mandatory; otherwise TLV2461QDRQ1 suffices for most automotive signal chains. |
| LMV931QDBVRQ1 | Lower supply current (120 μA vs. 500 μA); lower GBW (1.5 MHz); no shutdown pin; SOIC-5 package. | Ultra-low-power always-on monitoring where bandwidth <200 kHz and no shutdown control are acceptable. | Choose LMV931QDBVRQ1 only for battery-critical subsystems with relaxed speed requirements; TLV2461QDRQ1 remains preferred for ADC buffering and active filtering. |
Compared with TLV2461AQPWRQ1 and LMV931QDBVRQ1, TLV2461QDRQ1 uniquely balances 6.4-MHz bandwidth, rail-to-rail I/O, integrated shutdown, and AEC-Q100 Grade 1 compliance - making it the optimal choice for time-sensitive, mixed-signal automotive functions requiring both precision and power efficiency.

FAQ
What is the operating temperature range for TLV2461QDRQ1?
The TLV2461QDRQ1 is qualified per AEC-Q100 Grade 1 with an operating free-air temperature range of –40°C to +125°C. This specification is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and output drive capability - ensuring reliable operation in under-hood and cabin-mounted automotive ECUs.
Does TLV2461QDRQ1 support true rail-to-rail input and output?
Yes, TLV2461QDRQ1 supports rail-to-rail input with a common-mode range from –0.2 V to VDD + 0.2 V, and rail-to-rail output swing within 10 mV of both supply rails under 10-kΩ load. This enables full-scale signal utilization in 3.3-V and 5-V automotive systems without level-shifting circuitry.
What is the shutdown behavior of TLV2461QDRQ1?
When the SHDN pin is driven below 0.7 V, TLV2461QDRQ1 enters ultralow-power shutdown mode drawing just 0.3 μA per channel, and its output transitions to high-impedance state. The amplifier resumes normal operation within 7.65 μs after SHDN rises above 2 V - verified across –40°C to +125°C.
Can TLV2461QDRQ1 drive capacitive loads?
Yes, TLV2461QDRQ1 is stable driving up to 160 pF with 10-kΩ load, achieving 45° phase margin and 7-dB gain margin at unity gain. For loads exceeding 160 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to maintain stability in ADC buffer or cable-driving configurations.
Is TLV2461QDRQ1 pin-compatible with other TLV246x-Q1 variants?
TLV2461QDRQ1 in TSSOP-8 shares identical pinout with TLV2460QDRQ1 and TLV2462QDRQ1, but differs from TLV2463-Q1 (14-pin) and TLV2464A-Q1 (14-pin). Pin compatibility is limited to single- and dual-channel 8-pin variants; always verify pin functions using the official TI datasheet SGLS008F before board reuse.
