Product details
Overview
TLC2252TDA1 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 12 nV/√Hz input voltage noise density at 1 kHz. It operates from single-supply (3 V to 16 V) or split-supply (±1.5 V to ±8 V) configurations and supports high-impedance sensor interfacing in battery-powered instrumentation.
For engineers reviewing the TLC2252TDA1 datasheet, TLC2252TDA1 pinout, TLC2252TDA1 application, or TLC2252TDA1 equivalent, key selection considerations include micropower operation for extended battery life, rail-to-rail output swing for full ADC dynamic range utilization, low input bias current (<1 pA) for piezoelectric transducer signal conditioning, and validated performance over 0°C to 70°C ambient temperature.
Technical Context
The TLC2252TDA1 implements a LinCMOS™ process-based dual op-amp architecture optimized for ultra-low quiescent current and rail-to-rail output swing. Its input stage uses CMOS transistors to achieve sub-picoampere bias current and common-mode input range extending to the negative rail.
AC performance includes 175 kHz unity-gain bandwidth and 0.08 V/µs slew rate, with DC specifications fully characterized at room temperature per TI's bare-die screening standard. Electrical parameters are not warranted over temperature or AC conditions unless explicitly tested and documented by TI for this die variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V single-supply or ±1.5 V to ±8 V split-supply - enables direct interface with 3.3 V/5 V microcontrollers and legacy 12 V systems. |
| Quiescent Current | 150 µA per amplifier - supports multi-year battery life in portable gas sensors and wearable health monitors. |
| Input Offset Voltage | 60 µV max - reduces baseline error in precision bridge amplifier stages without trimming. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - preserves signal integrity when amplifying low-level outputs from thermopiles or strain gauges. |
| Output Swing | Rail-to-rail - delivers full-scale analog input to 12-bit ADCs without level-shifting circuitry. |
| Input Bias Current | <1 pA - prevents loading errors in high-Z sources like pH electrodes and photodiode transimpedance nodes. |
| Unity-Gain Bandwidth | 175 kHz - sufficient for anti-aliasing filtering and slow-control-loop compensation up to ~10 kHz closed-loop bandwidth. |
Pinout & Package
Bare die in waffle pack (TD package), thickness 10.5 mils, aluminum-copper-titanium-tungsten metallization, floating backside potential. Not intended for surface-mount assembly without custom die attach and wire bonding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT (Pad 1) | Amplifier A output | Drives external load or ADC input; rail-to-rail swing supports full supply utilization. |
| 1IN– (Pad 2) | Inverting input of Amp A | Accepts feedback network or differential signal; high impedance minimizes source loading. |
| 1IN+ (Pad 6) | Non-inverting input of Amp A | Connects to high-Z sensor node; common-mode range includes GND in single-supply mode. |
| VDD–/GND (Pad 7) | Negative supply / ground reference | Reference for both amplifiers; must be stable and low-noise for precision DC coupling. |
| 2IN+ (Pad 8) | Non-inverting input of Amp B | Independent high-impedance node for second sensor channel or reference buffer. |
| 2IN– (Pad 9) | Inverting input of Amp B | Supports dual-channel instrumentation amplifier configuration with matched external resistors. |
| 2OUT (Pad 13) | Amplifier B output | Provides second independent rail-to-rail output; usable for dual-sensor systems or power supply monitoring. |
| VDD+ (Pad 14) | Positive supply | Accepts 3–16 V; internal ESD protection requires proper decoupling near bond pads. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables maximum dynamic range utilization with 12-bit ADCs without external level shifters or gain adjustment. |
| 150 µA per amplifier supply current | Extends operating time in coin-cell-powered devices such as environmental data loggers and wireless sensor nodes. |
| <1 pA input bias current | Eliminates significant offset drift in transducer interfaces where source impedances exceed 100 MΩ. |
| 60 µV max input offset voltage | Reduces calibration frequency in medical front-ends and industrial process monitoring systems. |
| Single- and split-supply operation | Allows reuse of same die across portable (3.3 V) and industrial (±5 V) platforms without redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher quiescent current (600 µA per amp), wider supply range (2.7–6 V), lower noise (11 nV/√Hz) | Optimized for 3.3 V systems only; not rated for 12 V or ±8 V operation | Select when 3.3 V supply and higher speed (6 MHz GBW) are required, and power budget allows >4× increase. |
| OPA2333AIDR | Zero-drift architecture, 17 µV max offset, 50 µA per amp, but limited to 5.5 V max supply | Superior DC accuracy for long-term drift-sensitive applications; incompatible with >5.5 V supplies | Select when microvolt-level offset stability over time and temperature is critical, and supply is constrained to ≤5.5 V. |
Compared with TLV2462IDR and OPA2333AIDR, the TLC2252TDA1 uniquely balances ultra-low power (150 µA), wide supply flexibility (3–16 V), and rail-to-rail output in a bare-die format-making it optimal for custom hybrid modules requiring minimal footprint and thermal mass.

FAQ
What is the operating temperature range specified for the TLC2252TDA1 bare die?
The TLC2252TDA1 bare die is electrically screened at room temperature only. TI specifies no guaranteed performance over temperature for this variant; the device is intended for use in ambient environments from 0°C to 70°C, consistent with its orderable part marking and packaging documentation. Full parametric characterization across temperature is not performed per TI's bare-die screening standard for TLC2252TDA1.
Does the TLC2252TDA1 support rail-to-rail input voltage range?
No, the TLC2252TDA1 supports rail-to-rail *output* swing but its common-mode input voltage range extends only to the negative rail-not the positive rail. The input stage is designed for high impedance and low bias current, not full input rail coverage. This distinction is critical when designing single-supply circuits where input signals approach VDD.
Can the TLC2252TDA1 be used in place of packaged TLC2252 variants like the SOIC-8 version?
No-TLC2252TDA1 is a bare die with no leadframe or molded package, requiring custom wire bonding, die attach, and encapsulation. It is not a drop-in replacement for SOIC-8 or TSSOP-8 packaged versions. PCB layout, thermal management, and assembly processes differ fundamentally between die and packaged ICs.
What is the maximum recommended supply voltage for continuous operation of the TLC2252TDA1?
The TLC2252TDA1 is rated for continuous operation from 3 V to 16 V in single-supply mode or ±1.5 V to ±8 V in split-supply mode. Exceeding 16 V total supply (e.g., 9 V + 9 V = 18 V) risks permanent damage. TI's datasheet specifies 16 V absolute maximum, and the bare-die construction offers no additional margin beyond that limit.
Is there an SPICE macromodel available for the TLC2252TDA1?
Yes, TI provides a verified PSpice macromodel for the TLC2252 family, which applies to the TLC2252TDA1 die variant. The model captures DC accuracy, rail-to-rail output behavior, and small-signal AC response. It does not simulate die-specific parasitics (e.g., bond wire inductance or pad capacitance), so board-level simulations require manual addition of package-related elements.
