Product details
Overview
TLC252CPS 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 VDD = 5 V, unity-gain bandwidth of 1.7 MHz, 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 TLC252CPS datasheet, TLC252CPS pinout, TLC252CPS application, or TLC252CPS equivalent, this device is selected for ultra-low quiescent current (3.6 mA typ), wide supply flexibility (1.4–16 V), and stable unity-gain operation - critical when designing energy-constrained analog front-ends with high-impedance sources and tight offset budgets.
Technical Context
The TLC252CPS uses Texas Instruments' silicon-gate LinCMOS™ process to achieve extremely high input impedance (>1012 Ω), sub-picoamp input bias currents (0.6 pA typ), and stable input offset over temperature (1.8 µV/°C). 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 ranging from VDD–/GND to (VDD – 1.2 V) at 5 V supply, and features low-noise performance (25 nV/√Hz at 1 kHz) and 80 dB CMRR - making it suitable for transducer interfacing where DC accuracy and noise immunity are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct use with single-cell Li-ion, alkaline, or solar cells without regulation. |
| Input Offset Voltage (max) | 10 mV at 25°C - defines worst-case DC error in precision gain stages and sensor amplifiers. |
| Supply Current (two amps) | 3.6 mA typical at VDD = 5 V - balances speed and power for portable instrumentation. |
| Unity-Gain Bandwidth | 1.7 MHz at VDD = 5 V - supports audio-band and low-speed control loop applications. |
| Common-Mode Input Range | Includes negative rail (GND) - allows ground-referenced signal acquisition without level-shifting. |
| Input Bias Current (typ) | 0.6 pA at 25°C - preserves signal integrity with MΩ-range source impedances (e.g., pH electrodes). |
| CMRR | 80 dB min at 25°C - rejects power supply and reference noise in single-supply configurations. |
Pinout & Package
Package: 8-pin plastic DIP (P package), through-hole mounting, 0°C to 70°C operating temperature range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives loads up to 10 kΩ while maintaining linearity. |
| 2 | IN– A | Inverting input - high-impedance node sensitive to layout-induced leakage and noise. |
| 3 | IN+ A | Non-inverting input - referenced to GND or bias network; accepts signals down to VDD–/GND. |
| 4 | VDD– / GND | Power return and reference ground - must be low-impedance for stable common-mode rejection. |
| 5 | VDD | Positive supply - accepts 1.4–16 V; decoupling capacitor required near pin for stability. |
| 6 | OUT B | Second amplifier output - independent channel for dual-path signal processing or feedback. |
| 7 | IN– B | Inverting input of second op-amp - electrically isolated but thermally coupled to Channel A. |
| 8 | IN+ B | Non-inverting input of second op-amp - enables dual-sensor buffering or differential pair configuration. |
Key Features
| Feature | Design Value |
|---|---|
| True single-supply operation | Common-mode input includes GND - eliminates need for dual supplies or level-shifting in sensor front-ends. |
| Ultra-low input bias current | 0.6 pA typical - prevents loading of high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes. |
| Stable unity-gain configuration | Phase margin ≥46° at 5 V - ensures reliable closed-loop performance without external compensation. |
| Low-voltage capability | Operates down to 1.4 V - supports direct interface with emerging low-voltage microcontrollers and energy-harvesting systems. |
| ESD-protected inputs | Rated to 2000 V HBM - reduces risk of field failure during handling and PCB assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC272CP | Higher VIO (15 mV max), higher supply current (1.4 mA typ), same 8-pin DIP package. | Less suited for precision DC-coupled paths; better for AC-coupled general-purpose amplification. | Select when cost sensitivity outweighs offset and power constraints. |
| LM358N | Bipolar input (65 nA IIB), no rail-to-rail input, 30 V max supply, wider temp range (–40°C to 105°C). | Preferred for industrial environments requiring extended temperature operation and robustness over ultra-low bias. | Choose when interfacing with legacy 5 V/12 V systems and high-source-impedance is not present. |
Compared with TLC252CPS, TLC272CP trades lower cost for higher offset and bias current, while LM358N offers broader temperature support and higher voltage tolerance at the expense of input impedance and single-supply usability - making TLC252CPS optimal for new designs prioritizing low-power precision in portable or energy-harvested systems.

FAQ
What is the maximum supply voltage rating for the TLC252CPS?
The absolute maximum supply voltage for the TLC252CPS is 18 V, as specified in the Absolute Maximum Ratings table. However, the recommended operating range is 1.4 V to 16 V. Exceeding 16 V may compromise long-term reliability or parametric performance, especially at elevated temperatures. Always observe derating curves in the Dissipation Rating Table for thermal management at high VDD and ambient conditions.
Does the TLC252CPS support rail-to-rail output swing?
No, the TLC252CPS does not provide rail-to-rail output swing. At VDD = 5 V, its typical high-level output voltage (VOH) is 3.8 V and low-level output voltage (VOL) is 50 mV - meaning it swings within ~1.2 V of each rail. This limitation is inherent to its LinCMOS™ output stage architecture and must be accounted for in gain-setting and headroom calculations.
Can the TLC252CPS operate from a 1.5-V alkaline cell without regulation?
Yes, the TLC252CPS is explicitly characterized down to 1.4 V and functions reliably at 1.5 V. At this supply, it maintains usable gain (AVD ≥10 V/mV), common-mode input range including GND, and stable unity-gain operation - making it ideal for direct connection to single alkaline or NiMH cells in ultra-low-power sensor nodes.
How does the input offset voltage of TLC252CPS compare to TLC252ACPS and TLC252BCPS?
The TLC252CPS has a maximum input offset voltage of 10 mV at 25°C, whereas the TLC252ACPS is graded to 5 mV max and the TLC252BCPS to 2 mV max. All three share identical pinout, package, and electrical architecture - only the VIO grade differs. Selection depends on required DC accuracy versus cost and availability trade-offs.
Is the TLC252CPS pin-compatible with other dual op-amps in the TLC25x2 family?
Yes, all variants in the TLC252, TLC25L2, and TLC25M2 families - including TLC252CPS, TLC25L2CPS, and TLC25M2CPS - share identical 8-pin DIP (P) pinout and footprint. They differ only in bias current, bandwidth, and supply current profiles, allowing drop-in substitution where system-level performance margins permit.
