Product details
Overview
TLC252CDR from Texas Instruments is a LinCMOS™ dual operational amplifier in an 8-pin SOIC (D) package, rated for 0°C to 70°C operation. It delivers 10 mV max input offset voltage at 25°C, operates from 1.4 V to 16 V supply, supports true single-supply operation with rail-to-rail common-mode input down to the negative rail, and draws only 300 µA supply current per amplifier at 1.4 V - ideal for low-power battery-operated sensor signal conditioning.
For engineers reviewing the TLC252CDR datasheet, TLC252CDR pinout, TLC252CDR application, or TLC252CDR equivalent, this page provides verified pin functions, real-world use cases in energy-constrained systems, key trade-offs versus low-bias and medium-bias variants, and supply-chain-ready availability details for production design-in.
Technical Context
The TLC252CDR implements a silicon-gate LinCMOS™ process enabling stable input offset voltage (10 mV max), ultra-low input bias current (≤600 pA), and high input impedance (>1012 Ω). Its architecture supports unity-gain stability and true single-supply operation with common-mode input range extending to VDD–/GND.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1), operates down to 1.4 V, and maintains functional performance across 0°C to 70°C ambient - making it suitable for portable instrumentation and remote analog front-ends where power and voltage headroom are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct operation from single Li-ion, two alkaline cells, or regulated 3.3/5/12 V rails without level-shifting. |
| Input Offset Voltage (max) | 10 mV at 25°C - defines worst-case DC error in precision gain stages; tighter grades (A/B suffixes) available for <5 mV requirements. |
| Supply Current (per amp) | 300 µA at VDD = 1.4 V - allows continuous operation for years on coin-cell batteries in always-on monitoring circuits. |
| Common-Mode Input Range | Includes negative rail (VDD–/GND) - permits direct interfacing with ground-referenced sensors (e.g., thermistors, strain gauges) without biasing networks. |
| Unity-Gain Bandwidth | 1.7 MHz at VDD = 5 V - supports audio-band filtering, active anti-aliasing, and moderate-speed transducer amplification. |
| Input Bias Current (max) | 600 pA at 70°C - preserves accuracy in high-impedance source applications (e.g., pH electrodes, photodiode TIA feedback paths). |
| ESD Rating | 2000 V HBM - meets basic handling robustness for industrial assembly environments without requiring special ESD protocols. |
Pinout & Package
Package: 8-pin SOIC (D), surface-mount, tape-and-reel format (suffix R confirms reel packaging).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 10 kΩ while maintaining specified AC/DC performance. |
| 2 | IN− A | Inverting input of amplifier A - high-impedance node; sensitive to layout-induced noise coupling. |
| 3 | IN+ A | Non-inverting input of amplifier A - accepts signals from 0 V to VDD − 0.2 V at VDD = 5 V. |
| 4 | VDD–/GND | Ground reference for both amplifiers - must be low-impedance; shared return path for all analog signals. |
| 5 | VDD | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stability. |
| 6 | OUT B | Amplifier B output - electrically identical to Pin 1; enables dual-channel signal processing in same footprint. |
| 7 | IN− B | Inverting input of amplifier B - independent of amplifier A; supports differential or isolated channel configurations. |
| 8 | IN+ B | Non-inverting input of amplifier B - matches Pin 3 functionality; allows simultaneous dual-sensor conditioning. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends to VDD–/GND, eliminating need for input bias resistors when amplifying ground-referenced signals. |
| Ultra-low quiescent current | 300 µA per amplifier at 1.4 V enables multi-year battery life in wireless sensor nodes and portable medical devices. |
| Stable at unity gain | No external compensation required - simplifies PCB layout and reduces BOM count for buffer and gain-of-one applications. |
| LinCMOS™ process technology | Delivers picoampere-level input bias current and stable offset over temperature, outperforming bipolar op-amps in high-Z sensor interfaces. |
| Single-supply operation capability | Operates with VDD as low as 1.4 V and input common-mode down to GND - ideal for energy-harvesting and solar-powered systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC25L2CDR | Lower supply current (24 µA per amp at 5 V), higher input offset voltage (10 mV max), optimized for ultra-low-power operation. | Better suited for multi-year battery life in sub-10 µA sleep-cycle systems; trades bandwidth (85 MHz unity-gain) for current reduction. | Select TLC25L2CDR when average supply current is the dominant constraint and bandwidth >1 MHz is unnecessary. |
| TLC25M2CDR | Higher supply current (210 µA per amp at 5 V), faster slew rate (0.4 V/µs), wider unity-gain bandwidth (525 MHz). | Enables higher-frequency active filtering and faster settling in data acquisition front-ends; consumes ~7× more current than TLC252CDR at 5 V. | Select TLC25M2CDR when signal bandwidth exceeds 100 kHz and system power budget allows >200 µA per amplifier. |
Compared with TLC25L2CDR and TLC25M2CDR, the TLC252CDR occupies a balanced position: it delivers moderate speed (1.7 MHz GBW) and low power (300 µA at 1.4 V) without sacrificing rail-to-rail input capability or ESD robustness - making it optimal for general-purpose, battery-aware analog signal chains where neither extreme low power nor high speed dominates the specification.

FAQ
What is the maximum input offset voltage specification for TLC252CDR?
The TLC252CDR has a maximum input offset voltage of 10 mV at 25°C, as confirmed in the "Available Options" table and electrical characteristics section of the SLOS002I datasheet. This value applies across the full 0°C to 70°C operating range for the 'C' grade variant, and represents the worst-case DC error introduced by the amplifier under standard test conditions (VDD = 1.4 V, VO = 0.2 V, RS = 50 Ω).
Does TLC252CDR support true single-supply operation?
Yes, the TLC252CDR supports true single-supply operation. Its common-mode input voltage range includes the negative rail (VDD–/GND), allowing inputs to swing down to 0 V even when powered from a single positive supply. This is explicitly stated in the device description and verified in the recommended operating conditions table for VIC at VDD = 1.4 V, 5 V, and 10 V.
What package type and reel format does TLC252CDR use?
The TLC252CDR uses the 8-pin SOIC (D) package and is supplied in tape-and-reel format, as indicated by the 'R' suffix in the part number. The datasheet states: "The D package is available taped and reeled. Add the suffix R to the device type (e.g., TLC252CDR). Chips are tested at 25°C." No other package variants (e.g., PDIP or TSSOP) carry the 'R' suffix for this ordering option.
What is the supply current consumption of TLC252CDR at 1.4 V?
At VDD = 1.4 V and TA = 25°C, the TLC252CDR draws 300 µA supply current per amplifier (600 µA total for both amplifiers), as specified in the "Electrical Characteristics at Specified Free-Air Temperature, VDD = 1.4 V" table under the IDD parameter for the TLC252_C grade. This ultra-low current enables extended operation in energy-harvesting and battery-powered applications.
Is TLC252CDR unity-gain stable?
Yes, the TLC252CDR is unity-gain stable. The datasheet explicitly states "is stable at unity gain" in the device description and confirms this via phase margin measurements (46° at 25°C, VDD = 5 V) in the operating characteristics tables. No external compensation components are required for stable operation in gain-of-one configurations such as voltage followers.
