Product details
Overview
TLV2451AID from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable systems. It delivers 220 kHz gain-bandwidth, 23 µA supply current per channel, ±10 mA output drive, and operates from 2.7 V to 6 V - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2451AID datasheet, TLV2451AID pinout, TLV2451AID application, or TLV2451AID equivalent, key selection criteria include its −40°C to 125°C industrial temperature rating, 5-pin SOT-23 package, rail-to-rail I/O swing within 250 mV of rails under 2.5 mA load, and absence of shutdown functionality - distinguishing it from TLV2450/3/5 variants.
Technical Context
The TLV2451AID uses a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing (within 250 mV of each rail at 2.5 mA). Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate support stable unity-gain buffer and low-frequency instrumentation configurations.
It features 106 dB power supply rejection ratio (PSRR), 89 dB common-mode rejection ratio (CMRR), and 20 µV typical input offset voltage - all specified across the full −40°C to 125°C operating range. No internal shutdown control is present, confirming its role as a dedicated single-channel amplifier without enable/disable logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion, two-cell alkaline, and 3.3 V/5 V system rails without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - enables stable DC-coupled amplification up to ~20 kHz with gain ≥11, suitable for sensor signal conditioning. |
| Supply Current per Channel | 23 µA - allows continuous operation for years on coin-cell batteries in portable monitoring devices. |
| Input Offset Voltage (typ) | 20 µV - minimizes DC error in precision transducer interfaces like strain gauges or thermopiles. |
| Output Drive Capability | ±10 mA - directly drives 10 kΩ loads or ADC input buffers without external gain stages. |
| Rail-to-Rail I/O | Yes - preserves full dynamic range in 3 V systems; outputs swing to within 250 mV of VDD/GND at 2.5 mA load. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive sensors and industrial field equipment. |
Pinout & Package
TLV2451AID is housed in a 5-pin SOT-23 package (DBV), with exposed pad not electrically connected. The device has no shutdown pin and is functionally identical to TLV2451CD/ID in pin assignment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier Output | Delivers rail-to-rail output voltage; capable of sourcing/sinking ±10 mA into resistive loads. |
| 2 (GND) | Analog Ground Reference | Primary return path for input bias current and output current; must be low-impedance for noise immunity. |
| 3 (IN+) | Noninverting Input | High-impedance CMOS node accepting rail-to-rail common-mode voltages (0 V to VDD). |
| 4 (VDD+) | Positive Supply | Accepts 2.7–6 V; PSRR of 106 dB ensures minimal supply ripple coupling to output. |
| 5 (IN−) | Inverting Input | High-impedance CMOS node; matched to IN+ for low input offset voltage and drift. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Enables full utilization of 3 V supply headroom in battery-powered systems, maximizing SNR in low-voltage ADC interfaces. |
| 23 µA Supply Current | Reduces quiescent power to 69 µW at 3 V, extending runtime in wearable ECG or pulse oximeter front-ends. |
| 220 kHz Gain-Bandwidth | Supports stable unity-gain buffering of slow-moving sensor signals (e.g., pH, temperature) with <0.1% gain error. |
| 20 µV Typical Input Offset | Minimizes baseline drift in high-gain transducer amplifiers, reducing need for manual calibration or auto-zero circuitry. |
| −40°C to 125°C Operation | Validates performance across automotive cabin, industrial PLC, and outdoor environmental sensor deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2451CDR | Same electrical specs and pinout; rated for 0°C to 70°C only; tape-and-reel packaging. | Limited to commercial-temperature consumer electronics; unsuitable for automotive or industrial ambient conditions. | Select TLV2451CDR only for cost-sensitive, non-extended-temperature applications with volume tape-and-reel requirements. |
| OPA348AIDBVR | Higher 1 MHz GBW and 0.5 V/µs slew rate; 44 µA supply current; same 5-pin SOT-23 package. | Better suited for higher-frequency sensor interfaces (e.g., ultrasonic time-of-flight), but doubles power consumption. | Choose OPA348AIDBVR when bandwidth >500 kHz is required and 44 µA supply current is acceptable in the system budget. |
Compared with TLV2451CDR, TLV2451AID provides extended temperature qualification critical for field-deployed equipment; versus OPA348AIDBVR, it trades bandwidth for 48% lower supply current - prioritizing battery longevity over speed in ultra-low-power sensing nodes.

FAQ
What is the operating temperature range of the TLV2451AID?
The TLV2451AID is rated for operation from −40°C to 125°C, making it suitable for demanding environments such as automotive under-hood locations, industrial control cabinets, and outdoor environmental monitoring systems. This extended temperature range is confirmed in the "Recommended Operating Conditions" table of the official TI datasheet SLOS218F, and distinguishes TLV2451AID from commercial-grade variants like TLV2451CD.
Does the TLV2451AID include a shutdown pin?
No, the TLV2451AID does not include a shutdown pin. It is a single-channel amplifier without enable/disable functionality. Shutdown capability is only present in TLV2450, TLV2453, and TLV2455 variants - as explicitly stated in the device family description and pinout diagrams of the TLV245x datasheet. The TLV2451AID's 5-pin SOT-23 layout contains only OUT, GND, IN+, VDD+, and IN− terminals.
What is the typical input offset voltage of the TLV2451AID?
The TLV2451AID has a typical input offset voltage of 20 µV at 25°C, with a maximum of 1000 µV across the full −40°C to 125°C temperature range. This value is specified in the "Electrical Characteristics" tables for the 'A' grade (TLV245xA) in the TI datasheet SLOS218F, and reflects its precision performance among micropower op-amps.
Can the TLV2451AID drive a 10 kΩ load rail-to-rail?
Yes, the TLV2451AID can drive a 10 kΩ load with rail-to-rail output swing - delivering output voltages within 250 mV of both VDD and GND while sourcing or sinking 2.5 mA. This capability is documented in the "Description" section and verified in the "Electrical Characteristics" tables of the TLV245x datasheet, ensuring full dynamic range utilization in 3 V and 5 V systems.
What package type is used for the TLV2451AID?
The TLV2451AID is packaged in a 5-pin SOT-23 (DBV) package, as confirmed by the "TLV2450 and TLV2451 AVAILABLE OPTIONS" table and the "TLV2451 DBV PACKAGE" pinout diagram in the TI datasheet SLOS218F. This compact surface-mount package measures 2.9 mm × 1.6 mm × 1.1 mm and is RoHS-compliant.
