Product details
Overview
TLC2252TDA2 from Texas Instruments is a dual rail-to-rail output, very low-power operational amplifier in bare die form, featuring 150 µA typical supply current per amplifier, 60 µV max input offset voltage, and 1.5 mVpp low-frequency noise (0.1–10 Hz). It operates from ±1.35 V to ±8 V or 2.7 V to 16 V single supply, with common-mode input range extending to the negative rail - ideal for precision sensor signal conditioning in battery-powered instrumentation.
For engineers reviewing the TLC2252TDA2 datasheet, TLC2252TDA2 pinout, TLC2252TDA2 application, or TLC2252TDA2 equivalent, key selection considerations include its micropower operation, rail-to-rail output swing, low input bias current (1 pA typ), high input impedance (>1 TΩ), and suitability for interfacing with low-voltage ADCs in space-constrained embedded systems.
Technical Context
The TLC2252TDA2 implements a LinCMOS™ input stage enabling ultra-low input bias current and rail-inclusive common-mode range, paired with a CMOS output stage delivering rail-to-rail swing within 10 mV of either supply. Its quiescent current remains stable across temperature and supply voltage variations, supporting consistent battery life in portable devices.
Designed for single- or split-supply operation without external level-shifting circuitry, the device supports direct coupling to high-impedance sources like piezoelectric transducers and pH electrodes. AC performance is specified only at room temperature per bare-die screening requirements, with DC parameters fully characterized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V single supply or ±1.35 V to ±8 V dual supply - enables operation from coin-cell to industrial bus rails |
| Quiescent Current | 150 µA per amplifier (typ) - extends battery life in always-on sensing nodes |
| Input Offset Voltage | 60 µV (max) - reduces DC error in precision gain stages without trimming |
| Input Bias Current | 1 pA (typ) - preserves signal integrity from >1 TΩ sources such as glass electrodes |
| Output Swing | Within 10 mV of both rails (VDD+/VDD− or GND) - maximizes dynamic range into 12-bit+ ADCs |
| Low-Frequency Noise | 1.5 mVpp (0.1–10 Hz) - supports sub-microvolt resolution in slow-scan biosensors |
| Common-Mode Input Range | Includes negative rail (0 V in single supply) - eliminates need for negative bias on sensor outputs |
Pinout & Package
Bare die in waffle pack, thickness 10.5 mils, backside silicon with floating potential, AlCuTiW metallization (1540 nm). No leadframe or molded package - requires custom die attach and wire bonding.

| 1IN– (Pad 2) | Inverting input of Amp A | High-impedance node; sensitive to stray capacitance and ESD |
| 1IN+ (Pad 6) | Non-inverting input of Amp A | Accepts signals down to GND; critical for single-supply sensor interfaces |
| VDD–/GND (Pad 7) | Negative supply / ground reference | Primary return path; must be low-inductance bond to substrate |
| 2IN+ (Pad 8) | Non-inverting input of Amp B | Independent high-Z input for second channel; layout symmetry advised |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher quiescent current (550 µA per amp), wider supply range (2.7–6 V), no guaranteed rail-to-rail input | Better AC performance but unsuitable for sub-200 µA systems or true rail-in applications | Select when bandwidth >1 MHz is required and power budget allows |
| OPA333AIDBVR | Zero-drift architecture, 17 µV max offset, 58 µA per amp, single-channel only | Superior DC accuracy but lacks dual configuration and rail-in capability | Select for ultra-precision single-channel DC measurement where offset drift dominates error |
Compared with TLV2462IDR and OPA333AIDBVR, the TLC2252TDA2 uniquely balances dual-channel micropower operation, rail-to-rail input and output, and sub-100 µV offset - making it optimal for compact, battery-constrained analog front-ends requiring two matched amplifiers without zero-drift complexity.

FAQ
What is the maximum operating temperature range for the TLC2252TDA2?
The TLC2252TDA2 bare die is screened for DC parametric and functional testing at room temperature only. Per TI's bare-die specification, AC performance and operation over temperature are not warranted. The device is intended for use in ambient environments where thermal management ensures junction temperature remains within absolute maximum ratings (–40°C to +125°C), but full parameter guarantees apply only at 25°C.
Does the TLC2252TDA2 support rail-to-rail input?
No - the TLC2252TDA2 features rail-to-rail *output* swing and a common-mode input voltage range that includes the negative rail, but does not extend to the positive rail. Its input common-mode range is typically 0 V to VDD – 1.5 V in single-supply operation, limiting use with inputs near VDD unless buffered.
How many amplifiers are integrated in the TLC2252TDA2?
The TLC2252TDA2 contains two independent operational amplifiers in a single bare die. This dual configuration is confirmed in the device description, bond pad mapping (Pads 1–2–6 and Pads 8–9–13), and ordering nomenclature "TLC2252", where '2' denotes dual-channel functionality.
Is the TLC2252TDA2 RoHS compliant?
No - according to TI's Package Option Addendum, the TLC2252TDA2 has RoHS status marked "No". It is a non-RoHS-compliant bare die intended for specialized assembly processes where lead-free compliance is not mandated or where post-assembly finishing meets regulatory requirements.
What packaging format is supplied for the TLC2252TDA2?
The TLC2252TDA2 is supplied as bare die in a waffle pack, with 10 units per tube. It has no molded package, leadframe, or solderable terminations - requiring die attach, wire bonding, and custom encapsulation by the end user's assembly house.
