Product details
Overview
TLC2252IDR from Texas Instruments is a dual rail-to-rail output, very low-power operational amplifier in an SOIC-8 package. It delivers 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, and 1 pA typical input bias current, enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC2252IDR datasheet, TLC2252IDR pinout, TLC2252IDR application, or TLC2252IDR equivalent, key selection criteria include its –40°C to 125°C operating range, rail-to-rail output swing, low offset voltage (≤1500 µV max), and compatibility with single-supply (2.2 V to 8 V) or split-supply (±2.2 V to ±8 V) configurations.
Technical Context
The TLC2252IDR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current and micropower operation. Its input stage includes high-impedance CMOS transistors enabling common-mode input voltage range extending to the negative rail.
It features fully specified performance across –40°C to 125°C, with guaranteed input offset voltage ≤1500 µV, CMRR ≥70 dB, and supply voltage rejection ratio ≥80 dB - making it suitable for industrial sensing where thermal stability and power supply immunity are critical.
Key Specifications

|---|---|
| Supply Current | 70–125 µA per channel at 25°C - enables multi-year battery life in always-on monitoring systems |
| Input Bias Current | 1 pA typical - preserves signal integrity when amplifying high-impedance sources like piezoelectric sensors |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - supports low-noise signal acquisition without external filtering overhead |
| Output Swing | Rail-to-rail - maximizes dynamic range into ADCs operating at same supply, eliminating level-shifting circuitry |
| Common-Mode Input Range | Extends to negative rail - allows direct interfacing with ground-referenced transducers and single-supply front-ends |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial control environments |
| Input Offset Voltage | ≤1500 µV at 25°C - sufficient for mV-level DC-coupled sensor amplification without trimming |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, tape-and-reel compatible (R suffix denotes reel packaging).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input of amplifier A | Accepts differential input signal referenced to non-inverting input; high-impedance node requiring guarded layout |

| 3 | Output of amplifier A | Rail-to-rail capable output driving loads up to ±50 mA; connects directly to ADC input or filter stage |
| 4 | Negative supply / Ground | Return path for both amplifiers; must be low-impedance to maintain PSRR and noise performance |
| 5 | Non-inverting input of amplifier B | Independent input for second channel; identical electrical characteristics to pin 2 |
| 6 | Inverting input of amplifier B | Differential input for amplifier B; matched to pin 1 for common-mode rejection |

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full supply swing (e.g., 0 V to 5 V) - eliminates need for external level shifters when driving SAR or delta-sigma ADCs |
| Ultra-low input bias current | 1 pA typical - prevents loading errors in high-Z pH electrodes, photodiode transimpedance stages, or thermocouple cold-junction compensation |
| Low-noise architecture | 19 nV/√Hz at 1 kHz - reduces integrated noise floor in bandwidth-limited sensor channels without increasing gain-stage complexity |
| Wide supply range | 2.2 V to 8 V single or ±2.2 V to ±8 V dual - supports direct integration into 3.3 V, 5 V, and legacy ±5 V systems without regulators |
| Automotive-grade qualification | Specified over –40°C to 125°C - meets temperature requirements for engine control, cabin air quality, and ADAS sensor signal chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Higher output drive (±35 mA vs ±50 mA), wider input voltage range (to V– – 0.3 V), but higher supply current (125 µA/channel) | Better suited for driving heavier capacitive loads or rail-rail input + output; less optimal for ultra-low-power battery systems | Select TLV2432IDR when output current >50 mA or input rail-rail capability is required; TLC2252IDR preferred for <100 µA/channel constraints |
| OPA2333AIDR | Zero-drift architecture, 0.02 µV/°C offset drift, lower offset (10 µV max), but higher supply current (17 µA/channel) | Superior DC accuracy for precision weigh scales or medical diagnostics; not optimized for wide-temp industrial sensing | Choose OPA2333AIDR for µV-level offset stability over temperature; TLC2252IDR remains optimal for cost-sensitive, wide-temp, micropower applications |

FAQ
What is the maximum supply voltage for the TLC2252IDR?
The TLC2252IDR supports a maximum supply voltage of 8 V for single-supply operation or ±8 V for split-supply operation. Absolute maximum ratings specify VDD+ ≤ 8 V and VDD– ≥ –8 V. Exceeding these limits risks permanent device damage, and operation above recommended conditions (±2.2 V to ±8 V) is not guaranteed for parametric performance or reliability.
Does the TLC2252IDR support rail-to-rail input?
No, the TLC2252IDR provides rail-to-rail *output* swing but does not feature rail-to-rail *input*. Its common-mode input voltage range extends to the negative rail (VDD–/GND) but stops 1.5 V below the positive rail (VDD+ – 1.5 V) under recommended operating conditions. This design balances input stage headroom with low-voltage operation and is documented in the "Recommended Operating Conditions" table of the SLOS176D datasheet.
What is the input offset voltage specification for the TLC2252IDR?
The TLC2252IDR has a maximum input offset voltage of 1500 µV at 25°C and up to 1750 µV across its full operating temperature range (–40°C to 125°C). This value applies to the standard TLC2252I grade; the pin-compatible TLC2252AI variant offers tighter 850 µV max at 25°C but shares the same part number suffix structure and package.
Can the TLC2252IDR drive capacitive loads directly?
The TLC2252IDR is stable with capacitive loads up to 100 pF when configured for unity-gain operation with RL = 50 kΩ, as verified by phase margin (63°) and gain margin (15 dB) measurements in the datasheet. Driving larger capacitive loads (e.g., >500 pF) requires isolation resistance or feedback compensation to prevent oscillation, especially in high-gain configurations.
Is the TLC2252IDR suitable for automotive applications?
Yes, the TLC2252IDR is qualified for automotive applications per the I-suffix grade (–40°C to 125°C), with documentation confirming Q-Temp Automotive HighRel qualification, configuration control, and compliance with relevant automotive stress testing standards. It is explicitly listed in TI's automotive-grade product portfolio for cabin and chassis subsystems where extended temperature and long-term reliability are required.
