Product details
Overview
TLV2461QPWRQ1 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, and 500-μA supply current per channel while operating from 2.7 V to 6 V. It is qualified for AEC-Q100 Grade 1 (–40°C to +125°C) and used in HEV/EV battery management systems for precision signal conditioning before ADC buffering.
For engineers reviewing the TLV2461QPWRQ1 datasheet, TLV2461QPWRQ1 pinout, TLV2461QPWRQ1 application, or TLV2461QPWRQ1 equivalent, key selection criteria include rail-to-rail output swing, micropower shutdown mode (0.3 μA/channel), input offset voltage ≤2000 μV over temperature, ±80-mA output drive capability, and TSSOP-8 packaging for space-constrained automotive modules.
Technical Context
The TLV2461QPWRQ1 implements a CMOS input stage enabling rail-to-rail input common-mode range beyond supply rails and rail-to-rail output swing with high-output-drive capability up to ±80 mA. Its internal architecture supports stable operation with capacitive loads up to 160 pF and maintains ≥44° phase margin at unity gain with 10-kΩ load and 160-pF capacitance.
Shutdown control is implemented via a dedicated SHDN pin (Pin 8), which places the amplifier into ultralow-current mode (IDD(SHDN) = 0.3 μA/channel) while forcing the output into high-impedance state - critical for power-gated sensor interfaces in automotive body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - enables stable closed-loop operation up to ~100 kHz with moderate gain in sensor front-ends |
| Slew rate | 1.6 V/μs - supports fast transient response for motor current sensing or PWM feedback loops |
| Supply current (active) | 0.55 mA/channel at 5 V - allows continuous operation in always-on vehicle subsystems without excessive quiescent drain |
| Supply current (shutdown) | 0.3 μA/channel - reduces system standby power in infotainment or telematics modules during sleep mode |
| Input offset voltage | ≤2000 μV over –40°C to +125°C - ensures <0.1% error in 2-V full-scale battery cell voltage monitoring |
| Output drive | ±80 mA - directly drives 50-Ω transmission lines or low-impedance analog multiplexers without external buffers |
| Common-mode range | –0.2 V to VDD + 0.2 V - accommodates signals below ground or above supply in differential sensing topologies |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461AQPWRQ1 | Lower max input offset voltage (1500 μV vs. 2000 μV); same pinout, package, and specs otherwise | Better DC accuracy for high-precision voltage monitoring where offset drift dominates error budget | Select TLV2461AQPWRQ1 when <0.075% full-scale error is required at end-of-life temperature extremes |
| LMV931QDBVRQ1 | Lower bandwidth (1.5 MHz), higher supply current (120 μA), no shutdown pin; SOT-23-6 package | Cost-sensitive, space-constrained applications without need for shutdown or high-speed response | Choose LMV931QDBVRQ1 only if bandwidth <200 kHz suffices and PCB layout cannot accommodate TSSOP-8 footprint |

FAQ
What is the maximum operating supply voltage for TLV2461QPWRQ1?
The absolute maximum supply voltage for TLV2461QPWRQ1 is 6 V, as specified in the Absolute Maximum Ratings table. Operation beyond this voltage risks permanent device damage. Recommended operating range is 2.7 V to 6 V, supporting both 3.3-V and 5-V automotive subsystems. The device maintains rail-to-rail input and output functionality across this full range, enabling flexible integration into mixed-voltage domains without level shifters.
Does TLV2461QPWRQ1 support true rail-to-rail input common-mode range?
Yes, TLV2461QPWRQ1 supports a common-mode input voltage range from –0.2 V to VDD + 0.2 V, extending beyond both supply rails. This is enabled by its CMOS input stage and allows direct interfacing with signals referenced to ground, VDD, or intermediate voltages - critical for differential sensing in battery cell monitoring or motor phase current detection where inputs may swing below GND or above VDD during transients.
How does the shutdown function behave on TLV2461QPWRQ1?
When the SHDN pin (Pin 8) is pulled below 0.7 V, TLV2461QPWRQ1 enters ultralow-power shutdown mode with supply current reduced to 0.3 μA per channel. During shutdown, the output is placed in a high-impedance state - not driven to either rail - preventing loading of downstream circuitry. The amplifier resumes normal operation within 7.65 μs after SHDN rises above 2 V, enabling rapid wake-up in event-triggered automotive subsystems.
Is TLV2461QPWRQ1 compatible with capacitive loads?
TLV2461QPWRQ1 is stable with capacitive loads up to 160 pF when driving a 10-kΩ load, as verified by phase margin ≥44° at unity gain. For heavier loads (>100 pF), TI recommends adding a small series resistor (10–50 Ω) between the output and capacitor to maintain stability. This capability supports direct driving of ADC input capacitors, long traces, or EMI filters without external isolation components - simplifying layout in compact automotive modules.
What is the input offset voltage specification for TLV2461QPWRQ1 over temperature?
TLV2461QPWRQ1 has a maximum input offset voltage of 2200 μV over the full operating temperature range of –40°C to +125°C, with typical value of 100 μV at 25°C. Its temperature coefficient is 2 μV/°C, meaning offset drift contributes ≤250 μV over a 125°C span. This performance meets stringent requirements for battery cell voltage monitoring, where <0.1% full-scale error must be maintained across lifetime and temperature extremes.
