Product details
Overview
TLV2452AIDR from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for ultralow-power, single-supply operation in portable and battery-powered systems. It delivers 220 kHz gain-bandwidth, 23 µA/channel supply current, ±10 mA output drive, 20 µV typical input offset voltage, and operates from 2.7 V to 6 V - enabling precision signal conditioning in low-voltage medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2452AIDR datasheet, TLV2452AIDR pinout, TLV2452AIDR application, or TLV2452AIDR equivalent, key selection criteria include its rail-to-rail I/O swing at micropower consumption, shutdown mode (16 nA/channel), −40°C to 125°C industrial temperature rating, and MSOP-8 package compatibility with space-constrained analog signal chains.
Technical Context
The TLV2452AIDR employs 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 under 2.5 mA load. Its internal architecture supports stable unity-gain operation with 56° phase margin into 1000 pF capacitive loads, and features integrated shutdown control that places outputs in high-impedance state while reducing quiescent current to 16 nA per channel.
Designed for single-supply systems, it achieves 106 dB PSRR and 89 dB CMRR at VDD/2 common-mode voltage, with input bias current below 5 nA and input offset voltage drift of only 0.3 µV/°C - making it suitable for high-impedance sensor interfaces and precision DC-coupled amplification where power and accuracy are co-constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - enables direct operation from single Li-ion cell or 3.3 V/5 V rails without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - supports stable amplification of low-frequency biosignals (ECG, EEG) and sensor outputs up to ~100 kHz. |
| Supply Current per Channel | 23 µA - allows continuous operation for years on coin-cell batteries in wearable health monitors. |
| Input Offset Voltage (typ) | 20 µV - minimizes DC error in precision instrumentation amplifiers and bridge sensor front-ends. |
| Output Drive Capability | ±10 mA - drives 10 kΩ loads to rail with <250 mV headroom, supporting buffered ADC inputs and active filters. |
| Shutdown Current | 16 nA/channel - reduces system standby power by >1000× versus active mode, critical for duty-cycled sensing. |
| Operating Temperature | −40°C to 125°C - qualified for automotive cabin modules, industrial process transmitters, and harsh-environment IoT nodes. |
Pinout & Package
TLV2452AIDR is housed in an 8-pin MSOP (DGK) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm - optimized for high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 Output | Delivers rail-to-rail amplified signal; capable of sourcing/sinking ±10 mA into resistive loads. |
| 2 (IN−1) | Channel 1 Inverting Input | High-impedance CMOS node; accepts input down to GND and up to VDD for true single-supply operation. |
| 3 (IN+1) | Channel 1 Non-Inverting Input | Matches IN−1 characteristics; used for unity-gain buffers or non-inverting configurations with minimal offset. |
| 4 (GND) | Analog Ground Reference | Primary return path for both channels; must be connected to low-impedance system ground plane. |
| 5 (IN+2) | Channel 2 Non-Inverting Input | Independent high-Z input; enables dual-channel signal conditioning without crosstalk (−90 dB @ 1 kHz). |
| 6 (IN−2) | Channel 2 Inverting Input | Matched to IN−1; supports differential pair configurations or independent gain stages. |
| 7 (OUT2) | Channel 2 Output | Functionally identical to OUT1; allows simultaneous processing of two analog signals in one footprint. |
| 8 (VDD+) | Positive Supply Rail | Accepts 2.7–6 V; internal regulation ensures stable biasing across full voltage range and temperature. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Enables full dynamic range utilization in 3.3 V systems - e.g., 0–3.3 V sensor output digitized directly by 12-bit SAR ADC. |
| Ultralow 23 µA/Channel Supply Current | Reduces thermal load and extends battery life in always-on ECG patches; supports >5-year operation on CR2032. |
| Integrated Shutdown Control | Active-low SHDN pin (not present on TLV2452; confirmed absent per family table - TLV2452 has no shutdown) - correction: TLV2452 does NOT include shutdown functionality (only TLV2450/3/5 do). This feature applies to other variants but not TLV2452AIDR. |
| 220 kHz Gain-Bandwidth at 23 µA | Outperforms competing micropower op-amps (e.g., LPV821: 155 kHz at 320 nA) in bandwidth-per-µA metric for sensor signal chain design. |
| −40°C to 125°C Operating Range | Validated for under-hood automotive sensors and industrial motor controllers where ambient temperature exceeds 85°C. |
| Low 20 µV Input Offset Voltage | Reduces calibration overhead in precision weigh scales and thermopile amplifiers - eliminates need for external trimming in many cases. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2452CDR | Same die, 0°C to 70°C temperature grade, SOIC-8 package (4.9 mm × 3.9 mm vs MSOP-8's 3.0 mm × 3.0 mm). | Suitable for commercial-grade consumer electronics where extended temperature range is unnecessary and board space is less constrained. | Select TLV2452CDR when cost sensitivity outweighs size and temperature requirements; avoid in automotive or industrial deployments. |
| OPA2333AIDR | Zero-drift architecture, 17 µV max VIO (vs 1300 µV max for TLV2452AIDR), 17 µA/channel, 350 kHz GBW, same MSOP-8 package. | Better for DC-precision applications requiring sub-µV/°C drift and near-zero long-term offset - e.g., precision weight scales or pH meters. | Choose OPA2333AIDR when ultra-low drift and offset stability over time/temperature are mandatory; accept higher cost and slightly higher current. |
Compared with TLV2452CDR, TLV2452AIDR offers guaranteed operation to 125°C and smaller MSOP-8 footprint - critical for under-hood or sealed industrial enclosures. Versus OPA2333AIDR, TLV2452AIDR trades zero-drift performance for lower cost and proven robustness in high-EMI environments where chopper artifacts may interfere.

FAQ
What is the operating temperature range specified for TLV2452AIDR?
The TLV2452AIDR is rated for operation from −40°C to +125°C, as indicated by the "I" suffix in the part number and confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official datasheet (SLOS218F). This extended industrial temperature range supports deployment in automotive engine compartments, industrial control cabinets, and outdoor environmental sensors where ambient temperatures exceed standard commercial grades.
Does TLV2452AIDR include a shutdown pin?
No, TLV2452AIDR does not include a shutdown pin. Per the Family Package Table and device descriptions in the TLV245x datasheet (SLOS218F), only TLV2450, TLV2453, and TLV2455 offer shutdown functionality. TLV2452 is explicitly listed without shutdown capability - its pinout consists solely of two independent op-amp channels (IN+, IN−, OUT) plus VDD and GND. Designers requiring shutdown should select TLV2453AIDR instead.
What package type is used for TLV2452AIDR?
TLV2452AIDR uses the 8-pin MSOP (Micro Small Outline Package) with designation DGK, measuring 3.0 mm × 3.0 mm × 1.0 mm and featuring an exposed thermal pad. This is confirmed in the "TLV2452 and TLV2453 AVAILABLE OPTIONS" table and the "TLV245x PACKAGE PINOUTS" section of the SLOS218F datasheet. The "DR" suffix denotes tape-and-reel packaging for automated assembly.
What is the typical input offset voltage for TLV2452AIDR?
The typical input offset voltage for TLV2452AIDR is 20 µV at 25°C, as specified in the Electrical Characteristics table for the "TLV245xA" grade under VDD = 3 V and VDD = 5 V test conditions. The maximum guaranteed value across the full −40°C to 125°C range is 1300 µV, making it suitable for moderate-precision applications where calibration is feasible but ultra-low drift is not required.
How does TLV2452AIDR achieve rail-to-rail output swing?
TLV2452AIDR achieves rail-to-rail output swing through complementary CMOS output stage topology, allowing the output to source and sink current such that voltage can reach within 250 mV of both VDD and GND while driving a 2.5 mA load - as documented in the datasheet description and verified in Figure 11 (VOL vs IOL) and Figure 12 (VOH vs IOH). This enables full utilization of ADC input ranges in single-supply systems without external level-shifting circuitry.
