Product details
Overview
TLV2452IDR 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, ±10 mA output drive, and 23 µA/channel supply current across 2.7 V to 6 V operation - enabling high-precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2452IDR datasheet, TLV2452IDR pinout, TLV2452IDR application, or TLV2452IDR equivalent, key selection criteria include its rail-to-rail I/O swing at sub-100 µA quiescent current, 106 dB PSRR, shutdown mode (16 nA/channel), and MSOP-8 package compatibility with space-constrained analog signal chains.
Technical Context
The TLV2452IDR 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 220 kHz gain-bandwidth product and 0.11 V/µs slew rate support stable unity-gain buffering and low-frequency amplification without phase reversal.
It features independent shutdown control per channel (pins 5 and 8), placing outputs in high-impedance state while reducing supply current to 16 nA/channel. Fully specified from −40°C to +125°C, it operates reliably in industrial and automotive sensor interfaces where supply voltage varies between 2.7 V and 6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion, 3.3 V logic, and dual-supply ±1.35 V to ±3 V configurations |
| Gain-Bandwidth Product | 220 kHz - enables stable DC-coupled amplification up to ~20 kHz with 10× closed-loop gain |
| Supply Current per Channel | 23 µA - allows continuous operation for years on coin-cell batteries in always-on monitoring circuits |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly without external buffers in sensor interface stages |
| Input Offset Voltage | 20 µV (typ) - ensures <100 µV total error in 12-bit ADC front-ends with gain ≤100 |
| Power Supply Rejection Ratio | 106 dB - rejects ripple and noise from noisy DC-DC converters in mixed-signal PCBs |
| Rail-to-Rail I/O | Yes - maximizes dynamic range in 3 V systems, delivering >95% of full-scale output swing |
Pinout & Package
TLV2452IDR 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 instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers rail-to-rail buffered or amplified signal; high-impedance during shutdown |
| 2 (IN− A) | Channel A inverting input | Accepts differential or single-ended feedback; CMOS input draws <5 nA bias current |
| 3 (IN+ A) | Channel A non-inverting input | Direct connection to sensor output or reference; rail-to-rail common-mode range (0 V to VDD) |
| 4 (GND) | Analog ground reference | Common return for both channels; must be low-impedance path to system AGND |
| 5 (SHDN A) | Channel A shutdown control | Logic-low (<0.5 V @ 3 V supply) disables Channel A; draws <16 nA in shutdown |
| 6 (VDD+) | Positive supply rail | Accepts 2.7–6 V; decoupling capacitor (100 nF) required within 5 mm of pin |
| 7 (OUT B) | Channel B output | Independent rail-to-rail output; electrically isolated from OUT A except via shared VDD/GND |
| 8 (SHDN B) | Channel B shutdown control | Separate enable/disable control per channel - enables power-gating of unused signal paths |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3 V supply in precision sensor amplifiers without level-shifting circuitry |
| Ultralow 23 µA/channel supply current | Extends battery life in wearable ECG monitors and portable gas sensors operating continuously for >5 years on CR2032 |
| Independent per-channel shutdown | Reduces system-level power by >99.9% for inactive channels - critical in multi-sensor data loggers |
| 220 kHz GBW with 0.11 V/µs slew rate | Supports accurate amplification of slow-moving physiological signals (e.g., EEG, temperature) without distortion |
| 106 dB PSRR and 80 dB CMRR | Maintains signal integrity in noisy industrial environments with shared power rails and long sensor traces |

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 electrical specs but rated for 0°C to 70°C (C-suffix); lower max junction temperature (150°C vs 150°C same), no extended temp validation | Suitable only for commercial-grade consumer electronics; not qualified for industrial or medical use requiring −40°C startup | Select TLV2452CDR only for cost-sensitive, ambient-temperature applications with no thermal stress requirements |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift vs 0.3 µV/°C), higher 350 kHz GBW, but 17 µA higher IDD (40 µA/channel) | Better for DC-precision applications like weigh scales; less optimal for ultra-low-power battery life targets | Choose OPA2333AIDR when offset drift over temperature is the dominant error source, not quiescent current |
Compared with TLV2452CDR, TLV2452IDR guarantees operation down to −40°C and offers identical performance at higher reliability; versus OPA2333AIDR, it trades zero-drift precision for 43% lower supply current - making it superior for multi-year battery deployments where drift is managed via calibration.

FAQ
What is the operating temperature range for TLV2452IDR?
The TLV2452IDR is rated for operation from −40°C to +125°C (I-suffix grade), validated across this full industrial temperature range per TI's SLOS218F datasheet. This makes TLV2452IDR suitable for deployment in automotive engine compartments, outdoor industrial sensors, and medical devices requiring cold-start capability.
Does TLV2452IDR support true rail-to-rail input and output?
Yes, TLV2452IDR supports rail-to-rail input (common-mode range = 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 device description and electrical characteristics tables of the SLOS218F datasheet, enabling maximum dynamic range in 3 V systems.
How does the shutdown feature work on TLV2452IDR?
TLV2452IDR provides independent shutdown control on pins 5 (SHDN A) and 8 (SHDN B). Driving either pin below 0.5 V (at VDD = 3 V) disables its respective channel, reducing supply current to 16 nA/channel and placing the output in high-impedance state - verified in the "Electrical Characteristics" table under IDD(SHDN).
What package type is used for TLV2452IDR?
TLV2452IDR uses the 8-pin MSOP (DGK) package - a 3.0 mm × 3.0 mm surface-mount outline with exposed thermal pad. This is explicitly listed in the "TLV2452 and TLV2453 AVAILABLE OPTIONS" table and confirmed in the "PACKAGE PINOUTS" section of the SLOS218F datasheet.
Is TLV2452IDR pin-compatible with other TLV245x variants?
No - TLV2452IDR (MSOP-8) is not pin-compatible with TLV2450/1 (SOT-23-5/6) or TLV2453/4/5 (MSOP-10/TSSOP-14/16). Pin compatibility exists only within the same package variant; the MSOP-8 pinout for TLV2452IDR is unique to dual-channel non-shutdown-capable members of the family per the datasheet pinout diagrams.
