Product details
Overview
TLV2461QDR 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 - enabling high-fidelity buffering of ADC inputs in Q-temperature automotive systems.
For engineers reviewing the TLV2461QDR datasheet, TLV2461QDR pinout, TLV2461QDR application, or TLV2461QDR equivalent, this device is selected for precision analog front-ends where rail-to-rail swing, micropower shutdown (0.3 µA/channel), and operation across −40°C to 125°C are required in space-constrained SOT-23-6 layouts.
Technical Context
The TLV2461QDR employs a complementary 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 6.4 MHz GBW and 1.6 V/µs slew rate support stable unity-gain buffer configurations driving capacitive loads up to 160 pF while maintaining ≥44° phase margin.
It integrates a dedicated SHDN terminal that places the amplifier in ultralow-power mode (0.3 µA/channel) and forces output into high-impedance state - critical for power-gated sensor interfaces and battery-powered data acquisition systems requiring fast turnon/turnoff (<8 µs / <330 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable closed-loop gain up to 10× at 640 kHz without peaking. |
| Slew Rate | 1.6 V/µs - enables full-scale 2-Vpp step response within 1.25 µs for 12-bit ADC sampling. |
| Input Offset Voltage | 100 µV (typ) - contributes ≤0.0025% error in 4-V full-scale precision sensor amplification. |
| Supply Current | 500 µA/channel - allows continuous operation for >1 year on a 220 mAh coin cell at 3 V. |
| Output Drive | ±80 mA - drives 50 Ω transmission lines or multiple 10 kΩ ADC inputs directly. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode. |

Pinout & Package
TLV2461QDR is packaged in a lead-free, RoHS-compliant 6-pin SOT-23 (DBV) package with moisture sensitivity level 1 (MSL-1), rated for automotive temperature range (−40°C to 125°C). The package features gull-wing leads, 0.95 mm pitch, and 2.9 mm × 1.6 mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail swing (within 100 mV of rails) and ±80 mA sourcing/sinking capability. |
| 2 - GND | Analog ground reference | Primary return path for input bias, output load, and shutdown control; must be low-impedance. |
| 3 - IN+ | Noninverting input | Accepts common-mode voltages from 0 V to VDD; supports single-supply sensor interface topologies. |
| 4 - VDD+ | Positive supply | Operates from 2.7 V to 6 V; internal regulation ensures stable bias over supply ripple. |
| 5 - IN− | Inverting input | High-impedance node (10⁹ Ω differential resistance); used for feedback or differential sensing. |
| 6 - SHDN | Active-high shutdown control | Drives output to high-Z when <0.7 V (low); disables amplifier core at VIH ≥2 V (high). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3-V systems - e.g., 0–3 V ADC input scaling without level-shifting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IDR | Same electrical specs and pinout; qualified for −40°C to 125°C but not AEC-Q100 automotive grade. | Lacks automotive qualification documentation and test reports required for OEM vehicle programs. | Select TLV2461IDR only for industrial or commercial designs where automotive reliability certification is unnecessary. |
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C offset drift vs. TLV2461QDR's 2 µV/°C; higher 350 µA supply current. | Better long-term DC stability in precision weigh scales; less suitable for high-speed buffering due to 350 kHz GBW. | Choose OPA333AIDBVR when ultra-low drift dominates over speed and power; avoid for >100 kHz signal paths. |
Compared with TLV2461IDR, TLV2461QDR adds AEC-Q100 qualification and configuration control for automotive use; compared with OPA333AIDBVR, it trades zero-drift performance for 18× higher bandwidth and 30% lower supply current - making it optimal for cost-sensitive, high-speed automotive analog front-ends.

FAQ
What is the operating temperature range for TLV2461QDR?
The TLV2461QDR is qualified for operation from −40°C to 125°C (junction temperature), meeting Q-Temp automotive requirements. This rating is validated per AEC-Q100 stress test conditions and supports deployment in engine bay, transmission control, and ADAS camera modules where ambient extremes occur.
Does TLV2461QDR support true rail-to-rail input and output?
Yes, TLV2461QDR provides rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 100 mV of each rail at ±10 mA load). This is confirmed in the datasheet's "Common-Mode Input Voltage Range" and "Output Voltage Swing" specifications under both 3 V and 5 V supply conditions.
How does the shutdown function work on TLV2461QDR?
The SHDN pin (Pin 6) is active-high: driving it ≥2 V enables normal operation; pulling it ≤0.7 V places TLV2461QDR in shutdown mode with 0.3 µA/channel supply current and high-impedance output. Turnon time is 7.65 µs and turnoff time is 328 ns, enabling rapid power cycling in sensor nodes.
What package type is used for TLV2461QDR?
TLV2461QDR uses the 6-pin SOT-23 (DBV) package - a surface-mount, gull-wing leaded package measuring 2.9 mm × 1.6 mm with 0.95 mm pitch. It is lead-free, RoHS-compliant, and rated MSL-1, supporting standard reflow soldering profiles.
Is TLV2461QDR pin-compatible with other TLV246x variants?
TLV2461QDR shares identical pinout with TLV2461IDR, TLV2461CDR, and TLV2461AIDR in the DBV package. However, TLV2460 (single with shutdown) and TLV2462 (dual) have different pin assignments - always verify against the specific variant's pin diagram before PCB layout.
