Product details
Overview
TLC25L2CPWR from Texas Instruments is a low-power, dual-channel LinCMOS™ operational amplifier optimized for single-supply battery-powered systems. It features 2-mV max input offset voltage (B-grade), 1.4 V to 16 V supply range, rail-to-rail common-mode input down to the negative rail, and ultra-low 24 µA typical supply current (two amplifiers) at 5 V - enabling precision signal conditioning in energy-constrained sensor interfaces and portable instrumentation.
For engineers reviewing the TLC25L2CPWR datasheet, TLC25L2CPWR pinout, TLC25L2CPWR application, or TLC25L2CPWR equivalent, this device is selected for ultra-low quiescent current, true single-supply operation with extended common-mode range, and stable unity-gain performance - critical for high-impedance transducer buffering, solar-powered data loggers, and low-voltage analog front-ends where power budget and input headroom are constrained.
Technical Context
The TLC25L2CPWR implements a silicon-gate LinCMOS™ process, delivering extremely high input impedance (>1012 Ω), sub-picoamp input bias currents (typ. 0.7 pA at 25°C), and stable offset over temperature (1 µV/°C avg. coeff). Its architecture supports true single-supply operation with common-mode input extending to VDD–/GND, eliminating level-shifting requirements in ground-referenced sensor circuits.
It achieves unity-gain stability with 85 MHz typical bandwidth (at 5 V, RL = 1 MΩ) and 34° phase margin, while maintaining low noise (68 nV/√Hz at 1 kHz) and high CMRR (94 dB typ.) - making it suitable for DC-coupled, high-resolution measurement paths where offset drift and power efficiency dominate design trade-offs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct operation from single alkaline, Li-ion, or solar cells without regulation. |
| Input Offset Voltage (max) | 2 mV at 25°C - B-grade precision ensures <±2 mV error in DC-coupled gain stages without trimming. |
| Supply Current (typ., two amps) | 24 µA at 5 V - allows multi-year battery life in always-on remote sensors. |
| Common-Mode Input Range | Includes negative rail (VDD–/GND) - accepts 0 V referenced inputs without external biasing. |
| Unity-Gain Bandwidth (typ.) | 85 MHz at 5 V, RL = 1 MΩ - supports fast settling in low-noise, high-Z buffer applications. |
| Input Bias Current (typ.) | 0.7 pA at 25°C - preserves signal integrity in >100 MΩ source impedances (e.g., pH electrodes, piezoresistive sensors). |
| CMRR (typ.) | 94 dB - rejects power supply ripple and ground noise in single-supply systems. |
Pinout & Package
TLC25L2CPWR is housed in an 8-pin TSSOP (PW) package, 3.0 mm × 4.4 mm, 0.65 mm pitch, thermally enhanced for low-power operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives high-impedance loads directly; rail-to-rail swing capability simplifies interface to ADCs. |
| 2 | IN– A | Inverting input of Amp A - high-impedance node requiring guarded layout to preserve low bias current advantage. |
| 3 | IN+ A | Non-inverting input of Amp A - accepts signals down to GND; used for unity-gain buffer or reference follower. |
| 4 | VDD– / GND | Ground reference pin - must be connected to system ground; shared return for both amplifiers. |
| 5 | VDD | Positive supply pin - accepts 1.4–16 V; decoupling capacitor required near pin for stability. |
| 6 | OUT B | Amplifier B output - independent channel for dual-sensor conditioning or signal splitting. |
| 7 | IN– B | Inverting input of Amp B - electrically identical to Pin 2; supports differential pair configurations. |
| 8 | IN+ B | Non-inverting input of Amp B - enables dual-channel simultaneous acquisition without cross-talk. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IPW | Higher supply current (550 µA), 6.5 V max supply, 2.5 mV VIO (A-grade) | Not suitable for <2 V operation or sub-100 µA power budgets | Select when higher speed (6.4 MHz GBW) and rail-to-rail output are required over ultra-low IQ. |
| LPV521MG/NOPB | Lower IQ (320 nA), but only single-channel, 5.5 V max supply, 1.25 mV VIO (max) | Requires two devices for dual-channel use; lacks 16 V tolerance for industrial supplies | Select when nanoamp IQ dominates design priority and dual channels can be implemented with two singles. |
Compared with TLV2462IPW and LPV521MG/NOPB, the TLC25L2CPWR uniquely balances 2 mV precision, 1.4–16 V operation, and 24 µA IQ in a dual-channel TSSOP - making it irreplaceable for battery-backed industrial sensors needing wide supply range and guaranteed B-grade offset without sacrificing channel count.

FAQ
What is the maximum operating temperature range for the TLC25L2CPWR?
The TLC25L2CPWR is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade rating aligns with its intended use in indoor portable equipment and non-automotive industrial environments. The device's thermal shutdown protection and 150°C junction limit ensure reliability within this range under normal PCB layout and airflow conditions. Always verify board-level thermal rise when operating near 70°C ambient.
Does the TLC25L2CPWR support true rail-to-rail output swing?
No - the TLC25L2CPWR does not provide rail-to-rail output. Its output swing is typically within 0.2 V of the rails (e.g., 0.2 V to 4.8 V at 5 V supply). However, its input common-mode range *does* include the negative rail (VDD–/GND), enabling true single-supply input operation. For rail-to-rail output, consider TI's TLV2462 or newer LPV821 family, though at higher supply current.
Can the TLC25L2CPWR drive a 10 kΩ load at 5 V supply?
Yes - the TLC25L2CPWR can reliably drive a 10 kΩ load at 5 V. Electrical characteristics show VOH ≥3 V and VOL ≤50 mV into 10 kΩ at 25°C, confirming usable swing of ~2.95 V. Output current capability exceeds ±1 mA, well above the 0.5 mA required for 10 kΩ. For optimal linearity and settling, keep capacitive load ≤20 pF unless compensated per Figure 1 in the datasheet.
How does the TLC25L2CPWR differ from the TLC252CPWR and TLC25M2CPWR variants?
The TLC25L2CPWR is the low-power variant: it draws 24 µA vs. 1.4 mA (TLC252) or 285 µA (TLC25M2) at 5 V. It trades bandwidth (85 MHz vs. 1.7 MHz / 525 MHz) and slew rate (0.03 V/µs vs. 3.6 / 0.43 V/µs) for ultra-low IQ. All share the same B-grade 2 mV VIO, LinCMOS™ input, and pinout - making TLC25L2CPWR ideal when power dominates over speed.
Is the TLC25L2CPWR RoHS compliant and lead-free?
Yes - the TLC25L2CPWR is RoHS compliant and lead-free. The PW (TSSOP) package uses matte tin lead finish, and TI's official packaging information confirms compliance with Directive 2011/65/EU. No exemptions apply; Pb content is below 1000 ppm. Full material declarations and test reports are available via TI's Quality & Environmental page under part number TLC25L2CPWR.
