Product details
Overview
TLV2461ID 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 precision ADCs in battery-powered industrial sensors.
For engineers reviewing the TLV2461ID datasheet, TLV2461ID pinout, TLV2461ID application, or TLV2461ID equivalent, this device is selected for rail-to-rail dynamic range in 2.7–6 V systems, shutdown-enabled power management in automotive ECUs, and low-noise (11 nV/√Hz) analog front-ends requiring stable DC accuracy over −40°C to 125°C.
Technical Context
The TLV2461ID operates as a unity-gain-stable voltage-feedback op amp with rail-to-rail input common-mode range extending beyond VDD and GND, and rail-to-rail output swing delivering full-scale signal fidelity at low supply voltages. Its internal architecture supports micropower shutdown (0.3 µA/channel) with high-impedance output state, making it suitable for intermittent-sampling sensor interfaces.
It achieves 6.4 MHz bandwidth and 1.6 V/µs slew rate while maintaining only 500 µA quiescent current per channel, balancing AC performance and energy efficiency. Input noise voltage is specified at 11 nV/√Hz (1 kHz), and CMRR reaches 85 dB at VDD = 5 V - confirming suitability for precision DC-coupled amplification in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable closed-loop operation up to ~500 kHz at unity gain with adequate phase margin. |
| Slew Rate | 1.6 V/µs - enables clean reproduction of 100 kHz full-scale sine waves into 10 kΩ loads. |
| Supply Current | 500 µA/channel - allows continuous operation for >1 year on a single CR2032 coin cell in low-duty-cycle sensor nodes. |
| Input Offset Voltage | 100 µV (typ) - contributes ≤0.002% error in 5 V full-scale 12-bit ADC buffer applications. |
| Output Drive | ±80 mA - drives 62 Ω loads to rail while maintaining linearity, supporting active filter and DAC output stages. |
| Rail-to-Rail I/O | Input extends 200 mV beyond rails; output swings within 100 mV of rails at 10 mA - maximizes dynamic range in 3 V systems. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode, critical for ASIL-B automotive modules. |
Pinout & Package
TLV2461ID is packaged in an 8-pin SOIC (D package) with industry-standard pinout and thermal performance rated for 1022 mW at TA ≤ 25°C (θJA = 122.6°C/W).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output terminal - delivers rail-to-rail voltage with ±80 mA sourcing/sinking capability. |
| 2 | IN− | Inverting input - high-impedance node (1300 pA bias current) for feedback network connection. |
| 3 | IN+ | Non-inverting input - accepts common-mode signals from 0 V to VDD, enabling single-supply sensor interfacing. |
| 4 | GND | Analog ground reference - must be low-impedance and separated from digital ground in mixed-signal PCB layouts. |
| 5 | NC | No internal connection - left unconnected; no routing or stitching required. |
| 6 | SHDN | Active-high shutdown control - driven >2 V to enable, <0.7 V to enter 0.3 µA ultra-low-power state. |
| 7 | NC | No internal connection - electrically isolated; may be used as keep-out zone or thermal pad anchor. |
| 8 | VDD+ | Positive supply input - operates from 2.7 V to 6 V; requires local 100 nF ceramic decoupling capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3 V supply in single-ended configurations without level-shifting circuitry. |
| Micropower shutdown mode | Reduces total system quiescent current to sub-microamp level, extending battery life in wake-on-event architectures. |
| High output drive (±80 mA) | Eliminates need for external buffer stages when driving low-impedance loads like 50 Ω cables or SAR ADC reference inputs. |
| Low input noise (11 nV/√Hz) | Preserves SNR in front-end amplification of microvolt-level transducer signals (e.g., thermopiles, strain gauges). |
| Automotive temperature range (−40°C to 125°C) | Qualified for under-hood and transmission-control applications without derating or thermal monitoring overhead. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2461ID'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. | Select OPA333AIDR when offset drift dominates error budget over temperature; TLV2461ID preferred for bandwidth-sensitive ADC drivers. |
| LMV321IDBVR | Rail-to-rail output only (not input); 1.4 MHz GBW; 80 µA supply current; no shutdown function. | Lower power for always-on battery monitors; lacks rail-to-rail input needed for single-supply sensor biasing. | Choose LMV321IDBVR for ultra-low-quiescent applications where input common-mode range is not constrained; TLV2461ID required when full rail-to-rail input is mandatory. |
Compared with OPA333AIDR and LMV321IDBVR, TLV2461ID uniquely combines rail-to-rail input/output, 6.4 MHz bandwidth, shutdown capability, and −40°C to 125°C qualification - making it the only option among the three qualified for automotive signal conditioning with both precision and speed requirements.

FAQ
What is the operating temperature range for TLV2461ID?
The TLV2461ID is rated for operation from −40°C to 125°C, meeting automotive-grade requirements for under-dash and engine-compartment applications. This specification is confirmed in the "Recommended Operating Conditions" table of the SLOS220J datasheet, where the "I-suffix" designation explicitly defines this extended temperature range.
Does TLV2461ID support rail-to-rail input and output simultaneously?
Yes, TLV2461ID supports true rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 100 mV of rails at 10 mA). This dual rail-to-rail capability is explicitly stated in the device description and verified in electrical characteristics tables for VOH/VOL across supply voltages.
What is the shutdown behavior of TLV2461ID?
When SHDN (Pin 6) is pulled below 0.7 V, TLV2461ID enters ultralow-power shutdown mode drawing 0.3 µA per channel, and its output transitions to high-impedance state. This behavior is documented in the "Electrical Characteristics" section under IDD(SHDN) and confirmed in typical characteristics Figure 22.
Can TLV2461ID drive capacitive loads without oscillation?
TLV2461ID remains stable with capacitive loads up to 160 pF when driving 10 kΩ loads, as verified by phase margin measurements (44°–45°) in the "Operating Characteristics" tables. For loads >160 pF, external isolation resistance is recommended per Figure 14 guidance.
Is TLV2461ID pin-compatible with other TLV246x variants?
TLV2461ID uses the standard 8-pin SOIC (D) package shared with TLV2462ID and TLV2464ID, but pin functions differ: TLV2461ID has dedicated SHDN on Pin 6, whereas TLV2462ID places SHDN on Pin 5 and TLV2464ID integrates dual shutdown control. Direct substitution is not supported without schematic and layout review.
