Product details
Overview
TLV2461QD from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier designed for automotive and industrial 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 serves as a precision buffer for analog-to-digital converters in engine control units and battery monitoring systems.
For engineers reviewing the TLV2461QD datasheet, TLV2461QD pinout, TLV2461QD application, or TLV2461QD equivalent, this page provides verified electrical specifications, Q-temp automotive qualification context, shutdown functionality details, and real-world design implications for low-voltage, high-reliability analog front-ends.
Technical Context
The TLV2461QD implements a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing, critical for maximizing dynamic range in 3 V–6 V single-supply systems. Its internal architecture supports stable operation with capacitive loads up to 160 pF while maintaining ≥44° phase margin at unity gain.
It integrates a dedicated SHDN terminal that places the amplifier in ultralow-power mode (0.3 µA/channel), forcing output into high-impedance state-enabling power-gating in multi-stage sensor signal chains without affecting downstream circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - Enables stable closed-loop operation up to ~500 kHz at unity gain with minimal phase loss. |
| Slew Rate | 1.6 V/µs - Supports clean 1 VPP signals up to ~800 kHz before slew-induced distortion dominates. |
| Input Offset Voltage | 100 µV (typ) - Delivers ≤0.01% gain error in 1 V full-scale instrumentation amplifiers. |
| Supply Current | 500 µA/channel - Allows continuous operation in always-on automotive subsystems with <1 mW dissipation at 3 V. |
| Output Drive | ±80 mA - Drives 37.5 Ω loads directly (e.g., terminated transmission lines or low-RLOAD ADC references). |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - Maintains SNR > 90 dB for 20 kHz audio-band signals with 1 kΩ source impedance. |
| Shutdown Current | 0.3 µA/channel - Reduces system standby power by >99.9% versus active mode in wake-on-event architectures. |
Pinout & Package
TLV2461QD is supplied in an 8-pin ceramic DIP (JG) package rated for −40°C to 125°C operation and qualified per AEC-Q100 for automotive use. Pin 1 is identified by a beveled edge or molded "U" shape.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - left unconnected; no routing or grounding required. |
| 2 | IN− | Inverting input - accepts feedback network or differential signal path; high-impedance CMOS node. |
| 3 | IN+ | Non-inverting input - interfaces with sensors or reference sources; rail-to-rail common-mode range (0 V to VDD). |
| 4 | GND | Analog ground reference - must be low-impedance, star-connected to minimize noise coupling into input stage. |
| 5 | NC | No internal connection - electrically isolated; PCB pad may be omitted or grounded for mechanical stability only. |
| 6 | VDD+ | Positive supply - accepts 2.7 V to 6 V single supply or ±1.35 V to ±3 V split supply; bypass with 0.1 µF ceramic. |
| 7 | OUT | Amplifier output - rail-to-rail swing (within 100 mV of rails at ±80 mA), capable of sourcing/sinking 80 mA continuously. |
| 8 | SHDN | Active-high shutdown control - drives output to high-Z when <0.7 V; enables <1 µs turnon/turnoff timing in power sequencing. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461AQD | Lower max input offset voltage (1500 µV vs. 2200 µV over full temp range); same pinout, package, and Q-temp rating. | Better suited for high-precision DC-coupled applications like strain gauge bridges where offset drift dominates error budget. | Select TLV2461AQD when system-level offset error must remain <1.5 mV over −40°C to 125°C without calibration. |
| OPA333AIDR | Zero-drift architecture (0.02 µV/°C drift vs. 2 µV/°C); higher supply current (17 µA vs. 500 µA); SOIC-8 package only. | Superior long-term DC stability but incompatible with ultra-low-power or ceramic-DIP mechanical constraints. | Choose OPA333AIDR only if offset drift is the dominant specification and 34× higher supply current is acceptable. |
Compared with TLV2461QD, TLV2461AQD improves worst-case offset by 32% across temperature while retaining identical footprint and automotive qualification; OPA333AIDR trades 34× higher quiescent current for 100× lower drift, making it unsuitable for battery-backed or thermally constrained automotive modules.

FAQ
What is the operating temperature range for TLV2461QD?
The TLV2461QD is rated for −40°C to 125°C free-air temperature operation and is qualified to AEC-Q100 Grade 1 standards. This range is validated across all electrical parameters including input offset voltage, supply current, and output drive capability-making TLV2461QD suitable for under-hood automotive applications and industrial environments with extreme thermal cycling.
Does TLV2461QD support true rail-to-rail input and output operation?
Yes, TLV2461QD features both rail-to-rail input and output stages. Its CMOS input allows common-mode voltage range from GND to VDD, and its output swings within 100 mV of each rail at ±80 mA load. This capability is confirmed in the datasheet's electrical characteristics tables at VDD = 3 V and 5 V, enabling full utilization of low-voltage ADC input ranges without external level-shifting circuitry.
How does the shutdown function operate on TLV2461QD?
The SHDN pin on TLV2461QD is active-high: driving it below 0.7 V places the amplifier in ultralow-power shutdown mode (0.3 µA/channel), while pulling it above 2 V enables normal operation. During shutdown, the output enters high-impedance state-preventing loading of downstream circuits. Turnon/turnoff times are specified at 7.65 µs and 328 ns respectively, supporting fast power-gating in event-driven systems.
What package type is used for TLV2461QD?
TLV2461QD is packaged in an 8-pin ceramic dual in-line package (CERDIP or JG package), distinct from plastic DIP or surface-mount variants. This hermetically sealed ceramic package provides superior moisture resistance, thermal stability, and long-term reliability-critical for automotive and military-grade applications where extended lifetime and parameter stability under thermal stress are mandatory.
Is TLV2461QD pin-compatible with other members of the TLV246x family?
No-TLV2461QD uses an 8-pin JG package with NC pins at positions 1 and 5, whereas TLV2460 (single with shutdown) uses 6-pin SOT-23 or 8-pin DIP with different pin assignments. The TLV2461QD pinout is unique to its 8-pin ceramic DIP configuration and is not interchangeable with TLV2460, TLV2462, or TLV2464 variants without PCB redesign.
