Product details
Overview
TLV2461QPWR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier designed for low-voltage portable and automotive signal conditioning. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage across −40°C to 125°C. It buffers ADC front-ends in battery-powered sensor nodes and automotive body control modules.
For engineers reviewing the TLV2461QPWR datasheet, TLV2461QPWR pinout, TLV2461QPWR application, or TLV2461QPWR equivalent, this page provides verified electrical specifications, Q-temp automotive qualification context, shutdown behavior, package-specific thermal derating, and real-world use cases in precision analog signal chains requiring rail-to-rail swing and low quiescent power.
Technical Context
The TLV2461QPWR implements a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing with high-current capability. Its architecture supports stable unity-gain operation with 160 pF capacitive load and maintains ≥44° phase margin at 3 V and 5 V supplies.
It integrates a dedicated SHDN terminal that reduces per-channel supply current to 0.3 µA while placing the output in high-impedance state-enabling power gating in multi-amplifier systems without signal contention. The device is qualified per AEC-Q100 Grade 2 (−40°C to 125°C) and supports single-supply operation from 2.7 V to 6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - Enables stable closed-loop gain up to 10× at 640 kHz for anti-aliasing or sensor amplification. |
| Slew Rate | 1.6 V/µs - Supports 12-bit DAC output settling within 1 µs for fast control loop response. |
| Supply Current | 500 µA/channel - Allows continuous operation in always-on automotive subsystems with <1 mW per channel at 3 V. |
| Input Offset Voltage | 100 µV (typ) - Delivers ≤0.0025% error in 4–20 mA transmitter I/V conversion at 4 V full scale. |
| Rail-to-Rail Output | Swings within 100 mV of rails at ±10 mA - Maximizes dynamic range when driving SAR ADCs with 0–3.3 V reference. |
| Shutdown Current | 0.3 µA/channel - Reduces system standby power by >99.9% versus active mode in duty-cycled sensor interfaces. |
| Common-Mode Range | 0 V to VDD - Accepts inputs down to ground in single-supply configurations, eliminating level-shifting circuitry. |
Pinout & Package
TSSOP-8 (PW) package with 0.65 mm pitch, 3.0 mm × 4.4 mm footprint, and exposed thermal pad for enhanced power dissipation in automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail swing with ±80 mA sourcing/sinking; connects directly to ADC input or transducer load. |
| 2 (IN−) | Inverting input | Differential node for feedback networks; high-impedance CMOS input minimizes bias current error. |
| 3 (IN+) | Non-inverting input | Accepts signals from 0 V to VDD; enables true single-supply sensor interfacing without external bias. |
| 4 (GND) | Analog ground reference | Return path for input bias and output current; must be tied to clean system AGND plane. |
| 5 (NC) | No internal connection | Unbonded pin; left floating or grounded per layout best practices to reduce parasitic coupling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IPW | Same silicon, PW package, but industrial-grade (−40°C to 125°C) without AEC-Q100 qualification or Q-temp traceability. | Lacks automotive qualification documentation and extended reliability testing; suitable for non-automotive industrial use only. | Select TLV2461IPW only if AEC-Q100 compliance is not required and cost sensitivity outweighs qualification needs. |
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV max offset, 0.02 µV/°C drift, but lower 350 kHz GBW and ±25 mA output drive. | Better DC precision for ultra-low-drift applications (e.g., weigh scales), but insufficient bandwidth for fast ADC buffering. | Choose OPA333AIDBVR when microvolt-level offset stability dominates over speed and output current requirements. |
Compared with TLV2461QPWR, TLV2461IPW offers identical performance without automotive qualification overhead, while OPA333AIDBVR trades bandwidth and drive strength for superior DC accuracy-making TLV2461QPWR optimal for cost-sensitive, high-speed, automotive-qualified signal conditioning where rail-to-rail swing and robust output drive are essential.

FAQ
What is the operating temperature range for TLV2461QPWR?
The TLV2461QPWR is qualified for −40°C to 125°C ambient operation per AEC-Q100 Grade 2. This range is validated through accelerated life testing, thermal cycling, and high-temperature operating life (HTOL) stress-ensuring reliability in automotive under-hood and industrial control environments where sustained high-temperature exposure occurs.
Does TLV2461QPWR support single-supply operation?
Yes, TLV2461QPWR supports true single-supply operation from 2.7 V to 6 V. Its rail-to-rail input stage accepts common-mode voltages from 0 V to VDD, and its rail-to-rail output swings within 100 mV of both rails at ±10 mA load-enabling direct interfacing with 3.3 V or 5 V ADCs without level-shifting circuitry.
How does the shutdown feature work on TLV2461QPWR?
The SHDN pin on TLV2461QPWR is an active-low control: pulling it below 0.7 V places the amplifier in ultralow-power shutdown mode (0.3 µA/channel), while driving it above 2 V enables normal operation. During shutdown, the output enters high-impedance state-preventing signal contention in multi-amplifier systems or shared bus configurations.
What is the maximum capacitive load TLV2461QPWR can drive stably?
TLV2461QPWR maintains ≥44° phase margin and stable unity-gain operation with up to 160 pF capacitive load at 3 V and 5 V supplies, as confirmed in the datasheet's typical characteristics. For loads exceeding 160 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to preserve stability in ADC driver or cable-driving applications.
Is TLV2461QPWR pin-compatible with other TLV246x variants?
No-TLV2461QPWR (TSSOP-8) is not pin-compatible with TLV2460 (SOT-23-6) or TLV2462 (SOIC-8). While all share the same core amplifier functionality, pin assignments differ: TLV2461QPWR uses pins 5 and 8 as NC, whereas TLV2462 assigns them to second amplifier inputs. PCB layout must match the specific variant's pinout.
