Product details
Overview
TLC25L2CPSRG4 from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for ultra-low-power, single-supply operation down to 1.4 V, featuring 10 mV max input offset voltage (VIO), 20–34 µA typical supply current (IDD) at 5 V, and rail-to-rail common-mode input range extending to the negative rail. It serves as a precision analog signal conditioner in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC25L2CPSRG4 datasheet, TLC25L2CPSRG4 pinout, TLC25L2CPSRG4 application, or TLC25L2CPSRG4 equivalent, key selection criteria include its 1.4–16 V supply flexibility, 68 nV/√Hz input noise at 1 kHz, 85–100 MHz unity-gain bandwidth (B1), low-temperature drift (1.1 µV/°C αVIO), and compatibility with high-impedance transducer sources requiring minimal offset error.
Technical Context
The TLC25L2CPSRG4 employs Texas Instruments' silicon-gate LinCMOS™ process, delivering stable input offset voltage grades (10 mV max for 'C' suffix), extremely high input impedance (>10¹² Ω), and femtoamp-level input bias currents (≤60 pA). Its architecture supports true single-supply operation with common-mode input voltage spanning from VDD–/GND to within 0.2 V of VDD.
Designed for energy-constrained systems, it achieves stability at unity gain across supply voltages from 1.4 V to 16 V, exhibits 65–94 dB CMRR and kSVR over 0°C–70°C, and integrates internal ESD protection rated to 2000 V per MIL-STD-883C Method 3015.1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct operation from single alkaline, lithium, or solar cells without regulation. |
| Input Offset Voltage (VIO) | 10 mV max at 25°C - defines worst-case DC error in precision DC-coupled amplification stages. |
| Supply Current (IDD) | 20–34 µA typical at 5 V - supports multi-year battery life in always-on sensor nodes. |
| Unity-Gain Bandwidth (B1) | 85–100 MHz at 5 V - sufficient for anti-aliasing, active filtering, and moderate-speed signal conditioning. |
| Input Noise Voltage (Vn) | 68 nV/√Hz at 1 kHz - critical for preserving SNR in low-level transducer signal amplification. |
| Common-Mode Input Range | Extends to VDD–/GND - allows direct interfacing with ground-referenced sensors and single-ended sources. |
| Average Tempco (αVIO) | 1.1 µV/°C - ensures <1 µV drift over 10°C ambient change, supporting stable calibration in portable devices. |

FAQ
What is the maximum supply voltage rating for the TLC25L2CPSRG4?
The TLC25L2CPSRG4 has an absolute maximum supply voltage (VDD) rating of 18 V, though its recommended operating range is 1.4 V to 16 V. Operation above 16 V risks exceeding safe dissipation limits and may degrade long-term reliability, especially at elevated temperatures. Always observe derating curves in the datasheet's Dissipation Rating Table for the PS package.
Does the TLC25L2CPSRG4 support true rail-to-rail input operation?
Yes, the TLC25L2CPSRG4 supports true rail-to-rail input common-mode voltage range, explicitly including the negative rail (VDD–/GND). At VDD = 5 V, the common-mode input range is specified as –0.2 V to 3.5 V over the full temperature range (0°C to 70°C), enabling direct interface with ground-referenced sensors without level-shifting circuitry.
What is the typical input bias current of the TLC25L2CPSRG4 at 25°C?
The TLC25L2CPSRG4 exhibits a typical input bias current (IIB) of ≤60 pA at 25°C, with a maximum of 600 pA over the full 0°C to 70°C operating range. This ultra-low IIB stems from its LinCMOS™ silicon-gate process and makes it suitable for high-impedance applications such as piezoelectric sensor conditioning and pH electrode buffers.
Can the TLC25L2CPSRG4 drive capacitive loads without instability?
The TLC25L2CPSRG4 is unity-gain stable but exhibits reduced phase margin under capacitive loading: at 5 V, phase margin drops to 34° with CL = 20 pF and RL = 1 MΩ. For loads >100 pF, external isolation (e.g., series resistor) or reduced closed-loop gain is recommended. The datasheet confirms stability with CL ≤ 20 pF and RL ≥ 1 MΩ in unity-gain configuration.
Is the TLC25L2CPSRG4 RoHS-compliant and lead-free?
Yes, the TLC25L2CPSRG4 is manufactured in a RoHS-compliant, lead-free process and meets JEDEC J-STD-020 moisture sensitivity level (MSL) 2a requirements. The "G4" suffix denotes green (halogen-free) packaging, and the device is qualified for reflow soldering per IPC/JEDEC J-STD-020 standards.
