Product details
Overview
TLV2461AIP from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for low-voltage portable systems. 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 analog signal buffering in ADC front-ends and sensor interfaces.
For engineers reviewing the TLV2461AIP datasheet, TLV2461AIP pinout, TLV2461AIP application, or TLV2461AIP equivalent, key selection criteria include its −40°C to 125°C automotive-grade temperature range, shutdown capability (0.3 µA/channel), rail-to-rail output swing down to 100 mV from rails at 10 mA, and compatibility with 2.7–6 V single-supply operation.
Technical Context
The TLV2461AIP employs a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails, supporting full dynamic range in 3 V systems. Its output stage uses complementary push-pull architecture to achieve rail-to-rail swing while delivering ±80 mA into resistive loads.
It integrates a dedicated SHDN pin that places the amplifier in ultralow-power mode (0.3 µA/channel) with high-impedance output state. The device maintains stable unity-gain operation with ≥44° phase margin into 160 pF capacitive loads, supporting direct driving of sampling capacitors in SAR ADCs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports closed-loop bandwidth up to ~5.2 MHz at AV = 1, suitable for anti-aliasing and reconstruction filters. |
| Slew Rate | 1.6 V/µs - enables clean 100 kHz full-scale sine wave output at 2 VPP without distortion. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.004% gain error in precision 12-bit sensor signal conditioning paths. |
| Supply Current | 500 µA/channel - allows battery-powered designs to operate >1 year on a CR2032 coin cell in duty-cycled applications. |
| Output Drive | ±80 mA - drives 50 Ω transmission lines or 100 pF+ capacitive loads without external buffers. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in low-level audio and instrumentation amplifier stages. |
| Rail-to-Rail Output | Swings within 100 mV of rails at 10 mA - maximizes usable dynamic range in 3 V ADC interfaces. |
Pinout & Package
TLV2461AIP is housed in an 8-pin plastic DIP (P) package with 0.3-inch body width and through-hole mounting. Pin 1 is identified by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - left unconnected per TI pinout diagram for P-package variant. |
| 2 | IN− | Inverting input - accepts feedback network or differential signal source. |
| 3 | IN+ | Non-inverting input - connects to reference, sensor, or signal source with rail-to-rail common-mode range (0 to VDD). |
| 4 | GND | Analog ground reference - must be low-impedance return path for input bias and output current. |
| 5 | NC | No internal connection - electrically isolated; no PCB trace required. |
| 6 | VDD+ | Positive supply - operates from 2.7 V to 6 V single supply or ±1.35 V to ±3 V dual supply. |
| 7 | OUT | Amplifier output - delivers rail-to-rail swing and ±80 mA drive into resistive or capacitive loads. |
| 8 | NC | No internal connection - unused terminal; no routing needed. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends beyond rails; output swings to within 100 mV of VDD/GND at 10 mA - preserves headroom in 3 V systems. |
| Shutdown mode | 0.3 µA/channel quiescent current with SHDN pin assertion - enables microcontroller-controlled power gating in sleep states. |
| High output drive | ±80 mA sourcing/sinking - eliminates need for external buffer when driving ADC sample-and-hold capacitors or LED indicators. |
| Low input noise | 11 nV/√Hz at 1 kHz - maintains signal integrity in microphone preamps and thermocouple amplifiers. |
| Automotive qualification | Specified over −40°C to +125°C ambient - qualified for under-hood and infotainment subsystems per AEC-Q100 stress test requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CD | Same core architecture but rated for 0°C to 70°C; higher max input offset (2000 µV); no automotive qualification. | Restricted to commercial-grade consumer electronics; not suitable for under-hood or industrial control environments. | Select TLV2461CD only for cost-sensitive, non-automotive applications where extended temperature range is unnecessary. |
| OPA344UA | Lower noise (8 nV/√Hz), lower offset (50 µV), but no shutdown pin and higher supply current (750 µA); same 8-pin SOIC package. | Lacks power-gating capability; unsuitable for ultra-low-power wake-on-event architectures. | Choose OPA344UA when noise performance dominates over power budget and shutdown functionality is not required. |
Compared with TLV2461CD and OPA344UA, the TLV2461AIP uniquely combines automotive temperature rating, integrated shutdown, and rail-to-rail I/O in a through-hole DIP package - making it the only option for legacy industrial designs requiring field-replaceable, high-reliability op-amps with micropower control.

FAQ
What is the operating temperature range for TLV2461AIP?
The TLV2461AIP is specified for operation from −40°C to +125°C ambient temperature, meeting automotive-grade thermal requirements. This range is confirmed in the "Recommended Operating Conditions" table of the SLOS220J datasheet and applies to the 'A' grade suffix in the P-package variant. It supports under-hood and industrial control applications where extended thermal stability is mandatory.
Does TLV2461AIP have a shutdown function?
Yes, TLV2461AIP includes a dedicated shutdown (SHDN) function. When the SHDN pin is pulled below 0.7 V relative to GND, the amplifier enters ultralow-power mode drawing just 0.3 µA per channel, and the output transitions to high-impedance state. This feature is explicitly documented in the "Electrical Characteristics" section for VDD = 3 V and 5 V conditions, and applies to all TLV246x variants with shutdown capability including TLV2461AIP.
What is the maximum output current capability of TLV2461AIP?
The TLV2461AIP delivers ±80 mA output current when measured 1 V from either rail, as specified in the "Electrical Characteristics" table at VDD = 5 V. At VDD = 3 V, it sustains ±40 mA under the same condition. These values reflect sourcing and sinking capability into resistive loads and are validated across the full −40°C to +125°C operating range per TI's characterization data.
Is TLV2461AIP pin-compatible with other TLV246x variants?
No - TLV2461AIP in the 8-pin P (plastic DIP) package has a unique pinout with NC terminals at pins 1, 5, and 8, differing from the 5-pin DBV (SOT-23) and 8-pin D (SOIC) variants. The P-package pin mapping is explicitly shown in Figure 4 of the SLOS220J datasheet and is not interchangeable with other TLV246x packages without PCB redesign.
What supply voltage range does TLV2461AIP support?
TLV2461AIP operates from a single supply of 2.7 V to 6 V or split supplies of ±1.35 V to ±3 V, as defined in the "Recommended Operating Conditions" table. This range is guaranteed across the full −40°C to +125°C temperature range and enables direct interface with 3.3 V and 5 V logic domains without level-shifting circuitry.
