Product details
Overview
TLV2450AIPE4 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, ±10 mA output drive, 23 µA supply current per channel, and 20 µV typical input offset voltage across a 2.7 V to 6 V supply range - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2450AIPE4 datasheet, TLV2450AIPE4 pinout, TLV2450AIPE4 application, or TLV2450AIPE4 equivalent, key selection criteria include shutdown-enabled power gating (16 nA/channel), rail-to-rail swing under 2.5 mA load, industrial temperature support (−40°C to 125°C), and SOT-23-6 packaging for high-density PCB layouts.
Technical Context
The TLV2450AIPE4 implements a CMOS input stage with rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 250 mV of rails at 2.5 mA). Its internal shutdown control asserts high-impedance output and reduces quiescent current to 16 nA/channel when SHDN is pulled low relative to GND.
It operates across an expanded industrial temperature range (−40°C to 125°C) and is fully specified at both 3 V and 5 V supplies. The amplifier maintains 106 dB PSRR and 89 dB CMRR at VDD/2 common-mode voltage, supporting stable performance in noisy mixed-signal environments.
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 regulated 3.3 V/5 V rails without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - enables stable closed-loop operation up to ~20 kHz with unity-gain stability into 1000 pF loads. |
| Supply Current (per channel) | 23 µA - allows continuous operation for years on coin-cell batteries in always-on sensor nodes. |
| Input Offset Voltage (typ) | 20 µV - ensures ≤0.2 mV error in 100× gain instrumentation amplifiers at room temperature. |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly, eliminating need for external buffer stages in analog output circuits. |
| Shutdown Current (per channel) | 16 nA - reduces system standby power by >1000× versus active mode, critical for duty-cycled measurement systems. |
| Rail-to-Rail I/O | Yes - maximizes dynamic range in 3 V systems, delivering >2.7 VPP output swing into 10 kΩ at 3 V supply. |
Pinout & Package
TLV2450AIPE4 is housed in a 6-pin SOT-23 package (DBV) with exposed pad for thermal enhancement. Pin 1 is marked by a molded dot or beveled edge; the device uses standard SOT-23 footprint (2.9 mm × 1.6 mm, 0.95 mm height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage with ±10 mA sourcing/sinking capability; high-impedance during shutdown. |
| 2 (IN−) | Inverting input | CMOS input with 0.3 nA max bias current; supports common-mode range from GND to VDD. |
| 3 (IN+) | Non-inverting input | CMOS input matched to IN−; enables precision differential sensing with low input offset drift. |
| 4 (GND) | Analog ground reference | Return path for input signals and output load; must be low-impedance to minimize noise coupling. |
| 5 (SHDN) | Active-low shutdown control | Pull ≤0.5 V (at 3 V VDD) or ≤0.8 V (at 5 V VDD) to enter ultra-low-power mode; open or high disables shutdown. |
| 6 (VDD+) | Positive supply | Accepts 2.7–6 V; internal regulation ensures consistent biasing across full supply range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal utilization in 3 V systems - e.g., 0–3 V sensor outputs digitized directly by 12-bit SAR ADCs. |
| Ultralow 23 µA supply current | Permits integration into energy-harvesting nodes where average current budget is <100 µA across all peripherals. |
| 16 nA shutdown current | Allows microcontroller-gated operation: amplifier enabled only during 100 µs sampling windows, cutting average power by >99%. |
| 220 kHz GBW with 0.11 V/µs slew rate | Supports accurate amplification of ECG, pulse oximetry, and thermistor signals without phase lag or distortion. |
| Specified from −40°C to 125°C | Validates performance in automotive cabin modules, industrial motor controllers, and outdoor IoT enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2450CDR | Same architecture and specs, but rated for 0°C to 70°C and packaged in tape-and-reel SOT-23-6. | Lacks extended temperature qualification; suitable for commercial-grade consumer electronics only. | Select TLV2450CDR for cost-sensitive, non-industrial applications where ambient temperature stays below 70°C. |
| MCP6001T-E/OT | 25 µA supply current, 1 MHz GBW, no shutdown pin; 1.8–6.0 V supply range. | Higher bandwidth but no power-gating capability; requires external enable logic for low-power sequencing. | Choose MCP6001T-E/OT when higher speed is needed and shutdown functionality can be implemented externally via MOSFET gate control. |
Compared with TLV2450AIPE4, TLV2450CDR offers identical electrical performance but lacks industrial temperature rating, while MCP6001T-E/OT trades shutdown integration for higher bandwidth and wider supply range - making TLV2450AIPE4 optimal for thermally demanding, battery-constrained systems requiring autonomous power management.

FAQ
What is the operating temperature range for TLV2450AIPE4?
The TLV2450AIPE4 is qualified for operation from −40°C to 125°C, meeting industrial and automotive under-hood requirements. This extended range is confirmed in the datasheet's Recommended Operating Conditions table and validated across all electrical parameters including input offset voltage, supply current, and output drive capability.
Does TLV2450AIPE4 support true rail-to-rail input and output?
Yes, TLV2450AIPE4 supports rail-to-rail input (common-mode range from GND to VDD) and rail-to-rail output (swings within 250 mV of each rail while driving 2.5 mA). This is explicitly stated in the device description and verified in Figures 1–2 (input offset vs. common-mode voltage) and Figures 11–14 (output voltage vs. load current).
What is the shutdown behavior of TLV2450AIPE4?
When the SHDN pin is pulled low (≤0.5 V at 3 V VDD), TLV2450AIPE4 enters ultralow-power shutdown mode, reducing supply current to 16 nA per channel and placing the output in high-impedance state. The turnoff time is 836 ns and turnon time is 59 µs, as measured in the Operating Characteristics table.
Can TLV2450AIPE4 drive capacitive loads?
TLV2450AIPE4 is stable with capacitive loads up to 1000 pF, as confirmed by phase margin measurements (56° at 1000 pF, Figure 24). For loads >100 pF, a small series resistor (e.g., 10–50 Ω) at the output is recommended to maintain stability in high-speed configurations.
What package type is used for TLV2450AIPE4?
TLV2450AIPE4 uses the SOT-23-6 (DBV) package, a 6-pin surface-mount outline measuring 2.9 mm × 1.6 mm. The "E4" suffix denotes the TI-standard green (RoHS-compliant) plastic package with matte tin lead finish, as defined in TI's packaging nomenclature guide.
