Product details
Overview
TLV2452AID from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable 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 high-precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2452AID datasheet, TLV2452AID pinout, TLV2452AID application, or TLV2452AID equivalent, key selection criteria include its −40°C to 125°C industrial temperature range, MSOP-8 package footprint, shutdown-capable dual-channel architecture, and verified rail-to-rail swing under 2.5-mA load - critical for space-constrained, low-noise analog signal chains.
Technical Context
The TLV2452AID 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), supporting single-supply operation down to 2.7 V. Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate are specified at 5 V and 3 V, with stable unity-gain performance up to 1000 pF capacitive load.
It features independent shutdown control per channel (pins 5 and 8), reducing quiescent current to 16 nA/channel in shutdown mode while placing outputs in high-impedance state. The device is fully characterized across −40°C to 125°C and supports both single-supply (2.7–6 V) and split-supply (±1.35–±3 V) configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - enables direct integration into 3.3 V and 5 V systems without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - supports stable amplification of DC–200 kHz signals in sensor interfaces and instrumentation. |
| 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 - ensures sub-100 µV total error in precision 12-bit ADC front-ends at room temperature. |
| Output Drive Capability | ±10 mA - drives 10 kΩ loads with full rail-to-rail swing, eliminating need for external buffers in low-speed DAC outputs. |
| PSRR | 106 dB - rejects power supply noise effectively in noisy mixed-signal PCB environments. |
| Shutdown Current per Channel | 16 nA - reduces system standby power by >99.9% compared to active mode, critical for duty-cycled sensing. |
Pinout & Package
TLV2452AID is housed in an 8-pin MSOP (DGK) package with 0.65 mm pitch, measuring 3.0 mm × 3.0 mm × 1.0 mm - suitable for high-density portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Delivers rail-to-rail buffered signal; high-impedance when SHDN1 = low. |
| 2 (IN−1) | Channel 1 inverting input | Accepts differential input down to 0 V; CMOS input draws <5 nA bias current. |
| 3 (IN+1) | Channel 1 non-inverting input | Supports rail-to-rail common-mode range (0 V to VDD); matched to IN−1 for low offset. |
| 4 (GND) | Analog ground reference | Common return for both channels and shutdown logic; must be low-impedance for noise immunity. |
| 5 (SHDN1) | Channel 1 shutdown control | Active-low enable; pulls below 0.5 V (at 3 V) or 0.8 V (at 5 V) to disable Channel 1. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7–6 V; decoupling capacitor required within 1 cm for stability. |
| 7 (OUT2) | Channel 2 output | Independent rail-to-rail output; high-impedance when SHDN2 = low. |
| 8 (SHDN2) | Channel 2 shutdown control | Active-low enable; electrically isolated from SHDN1 for independent channel control. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V systems - e.g., 0–3.3 V sensor output digitization without clipping. |
| Ultralow 23 µA/channel supply current | Permits continuous operation in wearable ECG monitors with >2-year battery life on CR2032. |
| 16 nA/channel shutdown current | Reduces system idle power to nanoampere levels - essential for wake-on-event architectures in IoT nodes. |
| 220 kHz GBW with 0.11 V/µs slew rate | Supports accurate amplification of slow-moving physiological signals (e.g., EEG, temperature) without phase distortion. |
| −40°C to 125°C operating range | Validated for automotive cabin sensors and industrial field transmitters without derating. |

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 silicon, 0°C to 70°C temp range, SOT-23-8 package (larger footprint, lower thermal resistance). | Suitable for commercial-grade consumer electronics; lacks extended temperature qualification. | Select when cost sensitivity outweighs industrial temp requirement and board space permits larger package. |
| OPA2333AIDR | Zero-drift architecture, 0.02 µV/°C offset drift, 17 µA/channel, but only 350 kHz GBW and no shutdown function. | Better DC precision for long-term sensor calibration; unsuitable where dynamic channel disabling is needed. | Choose for ultra-stable DC gain applications (e.g., precision weigh scales); avoid where power cycling or event-triggered wake-up is required. |
Compared with TLV2452CDR, TLV2452AID offers guaranteed operation at −40°C and 125°C with identical electrical specs in MSOP-8, while OPA2333AIDR trades shutdown capability and wider temp range for superior offset drift and slightly lower quiescent current - making TLV2452AID optimal for ruggedized, duty-cycled portable instrumentation.

FAQ
What is the operating temperature range for TLV2452AID?
The TLV2452AID is rated for operation from −40°C to 125°C, meeting industrial and automotive under-hood requirements. This range is validated per TI's characterization across all electrical parameters including input offset voltage, supply current, and gain-bandwidth product - ensuring reliable performance in harsh environments without derating.
Does TLV2452AID support true rail-to-rail input and output operation?
Yes, TLV2452AID supports rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swings within 250 mV of each rail at 2.5 mA load). This is confirmed in the datasheet's "Rail-To-Rail Input/Output (RRIO)" feature list and verified in Figures 1–2 (input offset vs. common-mode voltage) and Figures 11–14 (output voltage vs. load current).
How does the shutdown function work on TLV2452AID?
TLV2452AID has two independent active-low shutdown pins (SHDN1 on pin 5, SHDN2 on pin 8). Driving either pin below 0.5 V (at 3 V supply) or 0.8 V (at 5 V supply) disables its respective channel, reducing supply current to 16 nA/channel and placing the output in high-impedance state. Both channels remain active when pins are pulled high to VDD.
What package type is used for TLV2452AID?
TLV2452AID uses the 8-pin MSOP (DGK) package - a surface-mount, gull-wing leaded package measuring 3.0 mm × 3.0 mm × 1.0 mm with 0.65 mm lead pitch. This is explicitly listed in the "TLV2452 and TLV2453 AVAILABLE OPTIONS" table for the A-suffix (−40°C to 125°C) grade.
Can TLV2452AID drive capacitive loads?
Yes, TLV2452AID maintains stability with capacitive loads up to 1000 pF, as confirmed by phase margin measurements in Figure 24 (56° at 1000 pF, RL = 10 kΩ). For loads >100 pF, TI recommends adding a small series resistor (e.g., 10–50 Ω) between output and capacitance to ensure robust phase margin across temperature and process variation.
