Product details
Overview
TLC25L2CPWRG4 from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for ultra-low-power, single-supply operation down to 1.4 V, with 10 mV max input offset voltage (VIO), 20 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 TLC25L2CPWRG4 datasheet, TLC25L2CPWRG4 pinout, TLC25L2CPWRG4 application, or TLC25L2CPWRG4 equivalent, key selection criteria include its 1.4–16 V supply flexibility, 68 nV/√Hz input noise at 1 kHz, 85 MHz unity-gain bandwidth at 5 V, and guaranteed operation across 0°C to 70°C commercial temperature range.
Technical Context
The TLC25L2CPWRG4 implements a silicon-gate LinCMOS™ process enabling extremely high input impedance (>10¹² Ω), sub-picoampere input bias currents (≤60 pA), and stable DC performance over temperature. Its architecture supports true single-supply operation with common-mode input voltage including ground and output swing near both rails under light loads.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1), unity-gain stability, and low-voltage operation without external level-shifting circuitry-making it suitable for direct interfacing with high-impedance transducers and microcontroller ADC inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - Enables operation from single alkaline or lithium coin cells up to industrial 12-V rails |
| Input Offset Voltage (VIO) | 10 mV max at 25°C - Sets baseline DC error budget for precision DC-coupled amplification |
| Supply Current (IDD) | 20 µA typical per amplifier at 5 V - Supports multi-year battery life in always-on sensing nodes |
| Unity-Gain Bandwidth | 85 MHz at 5 V, RL = 1 MΩ - Sufficient for anti-aliasing filters and moderate-speed signal conditioning |
| Input Noise Voltage | 68 nV/√Hz at 1 kHz - Critical for low-level thermocouple or strain gauge signal integrity |
| Common-Mode Input Range | Includes negative rail (GND) - Eliminates need for input biasing networks in single-supply designs |
| Operating Temperature | 0°C to 70°C - Qualified for commercial-grade embedded systems and portable equipment |
Pinout & Package
TLC25L2CPWRG4 is housed in an 8-pin TSSOP (PW) package with 0.65 mm pitch, moisture sensitivity level 1, and Pb-free finish compliant with JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 | IN− A | Inverting input - High-impedance node for feedback network connection or differential sensing |
| 3 | IN+ A | Non-inverting input - Accepts reference, sensor, or signal source with minimal loading |
| 4 | GND / VDD− | Power return - Shared ground reference for both amplifiers; must be low-impedance |
| 5 | VDD | Positive supply - Single rail powers both op-amps; decoupling capacitor required at pin |
| 6 | OUT B | Inverting amplifier output - Independent second channel for dual-signal processing or buffer + gain |
| 7 | IN− B | Inverting input - Matches Pin 2 functionality for second amplifier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower VIO (2 mV max), higher IDD (550 µA), rail-to-rail output only | Better DC accuracy but 27× higher quiescent current limits battery life | Select when precision outweighs power constraints; not drop-in due to different bias current and noise profile |
| LPV521MG/NOPB | Lower IDD (320 nA), lower bandwidth (155 kHz), same VIO grade (10 mV) | Optimized for nano-power, not high-speed signal conditioning | Choose for ultra-long-life applications where bandwidth <200 kHz suffices; pinout incompatible |
Compared with TLV2462IDR and LPV521MG/NOPB, the TLC25L2CPWRG4 uniquely balances sub-100 µA supply current, 85 MHz bandwidth, and 10 mV VIO-making it optimal for dual-channel, battery-powered signal chains needing both speed and efficiency.

FAQ
What is the maximum supply voltage rating for the TLC25L2CPWRG4?
The TLC25L2CPWRG4 has an absolute maximum supply voltage (VDD) rating of 18 V, as specified in the Absolute Maximum Ratings table. However, its recommended operating range is 1.4 V to 16 V. Exceeding 16 V may compromise parametric performance or reliability, even if below the 18-V stress limit. Always refer to the Recommended Operating Conditions section for design margins.
Does the TLC25L2CPWRG4 support true rail-to-rail input and output operation?
The TLC25L2CPWRG4 supports rail-to-rail input operation-its common-mode input voltage range includes the negative rail (GND) and extends up to VDD − 0.2 V at 5 V supply. However, its output swing is not rail-to-rail: typical VOH is 3.2 V and VOL is 0 mV at 5 V with 1-MΩ load. Output headroom depends on load; heavier loads reduce swing amplitude.
What is the input offset voltage specification for the TLC25L2CPWRG4, and how does it vary with temperature?
The TLC25L2CPWRG4 has a maximum input offset voltage (VIO) of 10 mV at 25°C, with a typical value of 1.1 mV. Its average temperature coefficient (αVIO) is 1.1 µV/°C over 25°C to 70°C, resulting in ≤100 µV additional drift across the full operating range. This makes it suitable for DC-coupled applications where thermal stability is critical but extreme precision is not required.
Can the TLC25L2CPWRG4 drive capacitive loads directly, and what is its phase margin?
The TLC25L2CPWRG4 is unity-gain stable and characterized with CL = 20 pF. At 5 V supply and 25°C, its phase margin is 34° under those conditions. Driving larger capacitive loads (>100 pF) without isolation resistance risks instability. For loads >50 pF, add a 10–100 Ω series resistor between output and capacitance to maintain stability, as confirmed in the Phase Margin test conditions.
Is the TLC25L2CPWRG4 pin-compatible with other devices in the TLC25x2 family, such as TLC252CPWR or TLC25M2CPWR?
Yes, the TLC25L2CPWRG4 shares identical 8-pin TSSOP (PW) package dimensions, pinout, and footprint with all members of the TLC25x2 family-including TLC252CPWR and TLC25M2CPWR. However, electrical characteristics differ significantly: TLC252 offers higher speed (3.6 V/µs slew rate) but 1.4 mA IDD; TLC25M2 provides 0.43 V/µs and 560 µA IDD. Swapping requires validation of bandwidth, noise, and supply current requirements.
