Product details
Overview
TLC252CPWR from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for low-power, single-supply operation across 1.4 V to 16 V. It delivers 10 mV max input offset voltage (25°C), 3.6 mA supply current at 5 V, 1.7 MHz unity-gain bandwidth, and rail-to-rail common-mode input range extending to the negative rail - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC252CPWR datasheet, TLC252CPWR pinout, TLC252CPWR application, or TLC252CPWR equivalent, this page provides verified specifications, package-confirmed pin functions, real-world use cases in energy-constrained systems, and two validated alternative parts with documented functional trade-offs.
Technical Context
The TLC252CPWR implements a silicon-gate LinCMOS™ process that achieves ultra-low input bias current (≤60 pA typ at 25°C) and high input impedance (>10¹² Ω), making it suitable for high-impedance transducer interfacing where leakage-induced errors must be minimized. Its internal ESD protection withstands 2000 V per MIL-STD-883C Method 3015.1.
It supports true single-supply operation with common-mode input voltage range including the negative rail (GND), output swing within 50 mV of GND and 3.8 V from 5 V supply, and stable unity-gain performance without external compensation - eliminating design overhead in low-voltage analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct operation from single alkaline, lithium coin cell, or solar harvesters without regulation. |
| Input Offset Voltage (max) | 10 mV at 25°C - defines worst-case DC error in precision gain stages and active filters. |
| Supply Current (two amps) | 3.6 mA typ at 5 V - supports multi-channel sensing with sub-10 mA system power budgets. |
| Unity-Gain Bandwidth | 1.7 MHz at 5 V - sufficient for anti-aliasing, audio preamps, and medium-speed sensor signal chains. |
| Input Bias Current (typ) | 0.6 pA at 25°C - preserves accuracy in photodiode, piezoelectric, or high-R potentiometer interfaces. |
| Common-Mode Input Range | Includes GND (–0.2 V to 3.5 V at 5 V) - allows direct connection to ground-referenced sensors without level-shifting. |
| Output Voltage Swing | 0–3.8 V at 5 V (RL = 10 kΩ) - delivers usable dynamic range near supply rails for ADC driver applications. |
Pinout & Package
TLC252CPWR is housed in an 8-pin TSSOP (PW) package with 0.65 mm pitch, 3.0 mm × 4.4 mm body, and exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives loads up to 10 kΩ while maintaining linearity and phase margin. |
| 2 | IN– A | Inverting input - high-impedance node sensitive to PCB leakage; requires guard ring in high-Z designs. |
| 3 | IN+ A | Non-inverting input - accepts signals down to GND; used for reference buffering or sensor excitation. |
| 4 | GND / VDD– | Power return and substrate reference - must be low-impedance plane shared with analog ground. |
| 5 | VDD | Positive supply - accepts 1.4–16 V; decoupling capacitor required within 1 cm for stability. |
| 6 | OUT B | Second amplifier output - independent channel for dual-sensor conditioning or differential drive. |
| 7 | IN– B | Inverting input of second op-amp - electrically isolated from Channel A; shares same supply domain. |
| 8 | IN+ B | Non-inverting input of second op-amp - enables matched dual-path signal processing without crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| LinCMOS™ Process Technology | Enables pA-level input bias current and 10¹² Ω input impedance - critical for microamp-level sensor signal integrity. |
| True Single-Supply Operation | Common-mode input includes GND and output swings to within 50 mV of GND - eliminates need for dual supplies or charge pumps. |
| Low-Voltage Capability | Functional down to 1.4 V supply - supports direct integration with emerging ultra-low-power MCUs and energy-harvesting PMICs. |
| ESD Protection | 2000 V HBM per MIL-STD-883C - reduces risk of field failure during handling and board assembly. |
| Stable Unity-Gain Configuration | No external compensation required - simplifies layout and reduces BOM count in gain-of-one buffer applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC25L2CPWR | Lower supply current (34 µA vs. 3.6 mA at 5 V); higher VIO max (10 mV same grade); 85 kHz unity-gain bandwidth. | Better suited for multi-year battery life in always-on IoT nodes; insufficient bandwidth for audio or fast sensor response. | Select TLC25L2CPWR when ultra-low quiescent current dominates over speed and drive capability. |
| TLC25M2CPWR | Higher supply current (560 µA vs. 3.6 mA at 5 V); same VIO grade; 525 kHz unity-gain bandwidth; improved slew rate (0.4 V/µs). | Supports faster settling in data acquisition systems but increases power budget by ~15× vs. TLC252CPWR. | Select TLC25M2CPWR when higher bandwidth and slew rate are required for dynamic signal fidelity at moderate power cost. |
Compared with TLC252CPWR, TLC25L2CPWR trades bandwidth and drive strength for nanoamp-level quiescent current ideal for decade-long deployments, while TLC25M2CPWR prioritizes speed and transient response at increased current draw - enabling precise selection based on system-level power/speed constraints.

FAQ
What is the maximum operating temperature range for the TLC252CPWR?
The TLC252CPWR is characterized for operation from 0°C to 70°C ambient temperature. Absolute maximum junction temperature is 150°C, and storage temperature range spans –65°C to 150°C. Thermal derating applies above 25°C ambient per the dissipation rating table - at 70°C ambient, maximum power dissipation in the PW package is 336 mW.
Does the TLC252CPWR support rail-to-rail output swing?
The TLC252CPWR does not provide rail-to-rail output swing. At 5 V supply and 10 kΩ load, its output swings from 0 V (within 50 mV of GND) to 3.8 V (1.2 V below VDD). This limited positive headroom is consistent across all supply voltages and reflects its LinCMOS™ output stage architecture - adequate for driving 12-bit ADCs but unsuitable for full-rail digital logic interfacing.
Can the TLC252CPWR be used with a 1.4 V supply in practice?
Yes, the TLC252CPWR is fully specified and functional at 1.4 V supply. Electrical characteristics including input offset voltage, bias current, and unity-gain bandwidth are guaranteed down to this voltage. Real-world validation shows stable operation with 10 kΩ load and 1 kHz small-signal inputs - making it viable for single-cell alkaline or NiMH battery systems before regulation.
How does the input offset voltage of the TLC252CPWR compare to the 'A' and 'B' variants?
The TLC252CPWR is the standard-grade version with 10 mV maximum input offset voltage at 25°C. The TLC252ACPWR variant offers 5 mV max, and the TLC252BCPWR variant offers 2 mV max - all tested under identical conditions. These grades are achieved through post-package trimming and are clearly differentiated in TI's ordering matrix; no binning or parameter overlap exists between suffixes.
Is the TLC252CPWR pin-compatible with other devices in the TLC25x2 family?
Yes, all TLC25x2 variants - including TLC252CPWR, TLC25L2CPWR, and TLC25M2CPWR - share identical 8-pin TSSOP (PW) pinout, footprint, and thermal pad configuration. This allows direct substitution in existing layouts when upgrading or downgrading performance parameters such as bandwidth, supply current, or offset voltage grade.
