Product details
Overview
TLV2461AQD from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier designed for high-reliability automotive and industrial signal conditioning. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 100 µV max input offset voltage (at 25°C), and 11 nV/√Hz input noise voltage - enabling precision buffering of analog-to-digital converters in extended-temperature systems.
For engineers reviewing the TLV2461AQD datasheet, TLV2461AQD pinout, TLV2461AQD application, or TLV2461AQD equivalent, this device is selected for low-power, high-output-drive analog front-ends in automotive sensor interfaces, battery-powered instrumentation, and industrial control loops where rail-to-rail swing and −40°C to 125°C operation are mandatory.
Technical Context
The TLV2461AQD employs a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails, paired with a robust output stage capable of sourcing/sinking ±80 mA while maintaining rail-to-rail swing. Its 6.4 MHz bandwidth and 1.6 V/µs slew rate are achieved at only 500 µA per channel supply current, balancing AC performance and micropower efficiency.
It integrates a dedicated shutdown terminal (SHDN) that reduces supply current to 0.3 µA/channel and places the output in high-impedance state - critical for power-gated subsystems in automotive ECUs and portable test equipment requiring dynamic power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer configurations up to ~6 MHz without phase margin degradation. |
| Slew Rate | 1.6 V/µs - enables clean 10-bit ADC sampling of signals up to ~100 kHz full-scale step response. |
| Input Offset Voltage | 100 µV (max at 25°C) - ensures ≤0.001% gain error in 10 V full-scale precision sensor amplifiers. |
| Supply Current | 500 µA/channel - allows continuous operation in always-on automotive modules with <1 mW per channel at 3 V. |
| Rail-to-Rail Output Swing | Within 100 mV of rails at ±40 mA load - maximizes dynamic range in single-supply 3.3 V or 5 V data acquisition systems. |
| Shutdown Current | 0.3 µA/channel - reduces standby power to <1 µW per channel, enabling multi-second battery life in wake-on-event sensors. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive applications and industrial motor control feedback paths. |
Pinout & Package
Ceramic flatpack (U) package, 8-pin, hermetically sealed, suitable for high-reliability automotive and military applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - unused pad; must be left floating or grounded per layout guidelines. |
| 2 | VDD | Positive supply rail - accepts 2.7 V to 6 V single supply or ±1.35 V to ±3 V split supply. |
| 3 | NC | No internal connection - unused pad; no electrical function. |
| 4 | OUT | Amplifier output - rail-to-rail capable, drives ±80 mA, high-impedance during shutdown. |
| 5 | NC | No internal connection - unused pad; not bonded internally. |
| 6 | GND | Analog ground reference - requires low-impedance connection to system ground plane. |
| 7 | IN− | Inverting input - high-impedance CMOS node (1 pA typical bias current) for feedback networks. |
| 8 | IN+ | Non-inverting input - rail-to-rail common-mode range (0 V to VDD) enables direct sensor interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of ADC input range in single-supply systems (e.g., 0–3.3 V), eliminating level-shifting circuitry. |
| ±80 mA output drive | Directly drives 50 Ω cables, multiple parallel inputs, or low-impedance transducers without external buffers. |
| 0.3 µA shutdown current | Reduces system quiescent power by >99.9% during idle periods - essential for ISO 16750-compliant automotive sleep modes. |
| 11 nV/√Hz input noise | Preserves SNR in low-level sensor amplification (e.g., thermocouples, strain gauges) without degrading resolution. |
| −40°C to +125°C operation | Qualified to AEC-Q100 Grade 1; supports placement near power stages or engine compartments without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461QD | Same electrical specs but rated for −40°C to +125°C (Q-suffix), packaged in plastic D (SOIC-8); lacks hermetic seal and military-grade reliability screening. | Approved for automotive but not qualified for aerospace or high-reliability industrial use; lower cost for non-hermetic designs. | Select TLV2461QD when AEC-Q100 compliance suffices and ceramic packaging is unnecessary. |
| OPA333AQDBVRQ1 | Zero-drift architecture; 0.1 µV/°C offset drift vs. TLV2461AQD's 2 µV/°C; 17 nV/√Hz noise; 350 µA supply current; no shutdown pin. | Better DC precision over temperature; unsuitable for high-output-drive or shutdown-controlled systems. | Choose OPA333AQDBVRQ1 only when ultra-low drift dominates design requirements and output drive <±20 mA is acceptable. |
Compared with TLV2461QD, TLV2461AQD provides hermetic ceramic packaging and extended reliability screening for mission-critical environments; compared with OPA333AQDBVRQ1, it trades zero-drift stability for higher output current, integrated shutdown, and proven rail-to-rail drive capability in harsh thermal cycles.

FAQ
What is the operating temperature range for TLV2461AQD?
The TLV2461AQD is specified for operation from −40°C to +125°C, qualified to automotive AEC-Q100 standards and screened for high-reliability applications. This range is explicitly confirmed in the "TLV2460M/AM/Q/AQ AVAILABLE OPTIONS" table, where TLV2461AQD appears under the −40°C to 125°C row with 1500 µV VIOmax at 25°C, matching its Q-suffix thermal grade and ceramic U-package construction.
Does TLV2461AQD include a shutdown feature?
Yes, TLV2461AQD includes a dedicated shutdown (SHDN) terminal. When the SHDN pin is driven below 0.7 V relative to GND, the amplifier enters ultralow-power mode with supply current reduced to 0.3 µA per channel, and the output transitions to high-impedance state - a feature confirmed in both the functional description and electrical characteristics tables for TLV2460/3/5 variants, which include TLV2461AQD in the same family grouping.
What package type is used for TLV2461AQD?
TLV2461AQD is supplied in an 8-pin ceramic flatpack (U) package, as verified in the "TLV2460M/AM/Q/AQ AVAILABLE OPTIONS" table and the "TLV246x PACKAGE PINOUTS" section, which shows the U-package pinout with NC, VDD, NC, OUT, NC, GND, IN−, and IN+ assignments - consistent with MIL-PRF-38534 qualified hermetic packaging for high-reliability deployment.
What is the maximum output current capability of TLV2461AQD?
TLV2461AQD delivers ±80 mA output current when measured 1 V from either rail, as specified in the "Electrical Characteristics at VDD = 5 V" table under the IO parameter. This high drive strength is maintained across the full −40°C to +125°C operating range and enables direct interfacing with low-impedance loads such as transmission lines, multiple parallel inputs, or power transducer drivers without external buffers.
Is TLV2461AQD pin-compatible with other TLV246x variants?
No - TLV2461AQD uses an 8-pin U-package with specific NC/IN+/IN−/GND/NC/VDD/NC/OUT pinout, whereas TLV2461 variants in SOIC-8 (D) or TSSOP-8 (PW) packages follow different pin mappings (e.g., IN+, IN−, VDD+, GND, SHDN, OUT). The U-package pinout shown in Figure 5 confirms distinct terminal ordering, making TLV2461AQD not pin-compatible with surface-mount versions despite functional equivalence.
