Product details
Overview
TLC25M2CPWLE from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for low-power, single-supply operation down to 1.4 V, featuring 2-mV maximum input offset voltage (B-grade), 0.40 V/µs slew rate at 5 V, and 525 kHz unity-gain bandwidth - ideal for battery-powered sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the TLC25M2CPWLE datasheet, TLC25M2CPWLE pinout, TLC25M2CPWLE application, or TLC25M2CPWLE equivalent, key selection criteria include its rail-to-rail input common-mode range (extends to negative rail), ultra-low 210–560 µA supply current across temperature, and TSSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TLC25M2CPWLE implements a silicon-gate LinCMOS™ process enabling stable input offset voltage grading (2 mV max), extremely high input impedance (>1012 Ω), and sub-1 pA input bias current - critical for interfacing with high-impedance transducers and precision analog front-ends.
It supports true single-supply operation with common-mode input voltage spanning from VDD–/GND to within 0.2 V of VDD, delivers 3.2–3.9 V output swing into 100-kΩ load at 5 V supply, and maintains stability at unity gain without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct integration with single-cell Li-ion, alkaline, or solar-cell power sources |
| Input Offset Voltage (max) | 2 mV at 25°C - ensures ≤2 mV DC error in precision DC-coupled amplification stages |
| Supply Current (two amps) | 210–560 µA at 5 V, 25°C - reduces quiescent power to <1.1 mW for always-on sensing nodes |
| Unity-Gain Bandwidth | 525 kHz at 5 V - supports audio-band and low-speed control loop signal processing |
| Slew Rate | 0.40 V/µs at 5 V - limits large-signal transient response to avoid distortion in buffered sensor outputs |
| Input Common-Mode Range | Extends to VDD–/GND - allows direct interface with ground-referenced thermistors or bridge sensors |
| ESD Protection | 2000 V HBM - meets MIL-STD-883C Method 3015.1 for robust handling in production environments |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm body, 0.65 mm pitch, exposed pad not electrically connected, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 100 kΩ with 3.2–3.9 V swing at 5 V supply |
| 2 | IN– A | Inverting input of Amp A - high-impedance node (<1 pA bias) for feedback network connection |
| 3 | IN+ A | Non-inverting input of Amp A - accepts signals from 0 V to VDD–0.2 V in single-supply mode |
| 4 | VDD–/GND | Ground reference for both amplifiers - must be low-impedance return path for precision performance |
| 5 | VDD | Positive supply rail - accepts 1.4–16 V; decoupling capacitor required near pin for stability |
| 6 | OUT B | Amplifier B output - independent channel for dual-path signal conditioning or differential drive |
| 7 | IN– B | Inverting input of Amp B - electrically isolated from Amp A; shares same VDD/GND references |
| 8 | IN+ B | Non-inverting input of Amp B - enables simultaneous dual-channel sensor buffering or active filtering |
Key Features

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 | Higher 1.2-V/µs slew rate, 6.5-mV VIO (A-grade), 1.25-mA supply current - trades power for speed | Better suited for higher-bandwidth active filters but consumes 5× more current than TLC25M2CPWLE | Select when >1-MHz GBW or faster settling is required; avoid if battery life is primary constraint |
| LMV358IDGKR | Rail-to-rail output, 7-V/µs slew rate, 7-mV VIO, 160-µA supply current - lower VIO spec but no negative-rail input capability | Acceptable for generic buffering where input common-mode does not reach GND | Choose only if input signals stay ≥0.2 V above GND; unsuitable for true single-supply transducer interfaces |
Compared with TLV2462IDR and LMV358IDGKR, the TLC25M2CPWLE uniquely combines 2-mV VIO, rail-to-rail input including GND, and sub-600-µA supply current - making it the only option among the three viable for precision, ultra-low-power, single-supply sensor front-ends.

FAQ
What is the maximum input offset voltage specification for TLC25M2CPWLE?
The TLC25M2CPWLE is a B-grade device with a maximum input offset voltage of 2 mV at 25°C, and 3 mV across the full 0°C to 70°C operating temperature range. This specification is guaranteed per the SLOS002I datasheet and applies to both amplifiers in the dual package. The 2-mV VIO enables high-accuracy DC amplification without external nulling circuitry in the TLC25M2CPWLE design.
Does TLC25M2CPWLE support true single-supply operation with input signals at ground potential?
Yes, the TLC25M2CPWLE supports true single-supply operation with its common-mode input voltage range extending to VDD–/GND (i.e., 0 V). At 5 V supply, the input common-mode range is specified as –0.2 V to 3.5 V across temperature, allowing direct interface with ground-referenced sensors such as thermistors, strain gauges, or bridge circuits without level-shifting components in the TLC25M2CPWLE application.
What is the typical supply current consumption of TLC25M2CPWLE at 1.4 V supply?
At 1.4 V supply and 25°C, the TLC25M2CPWLE draws 200–250 µA total supply current for both amplifiers under no-load conditions, as confirmed in the "electrical characteristics at VDD = 1.4 V" table of the SLOS002I datasheet. This ultra-low quiescent current enables multi-year operation from primary lithium cells and makes the TLC25M2CPWLE especially valuable in always-on sensing applications.
Is TLC25M2CPWLE pin-compatible with other devices in the TLC25x2 family?
Yes, the TLC25M2CPWLE uses the standard 8-pin TSSOP (PW) footprint shared across all TLC25x2 dual op-amps, including TLC252CPW, TLC25L2CPW, and their A/B-suffix variants. Pin functions (1–8) are identical per the top-view diagram in the datasheet, enabling drop-in substitution within the same package variant - provided the VIO grade and supply current requirements align with the TLC25M2CPWLE specifications.
What is the unity-gain bandwidth of TLC25M2CPWLE at 10 V supply?
At 10 V supply and 25°C, the TLC25M2CPWLE has a typical unity-gain bandwidth of 635 kHz, with a minimum of 510 kHz across the 0°C to 70°C temperature range. This value is measured under standard conditions (VI = 10 mV, CL = 20 pF) and reflects the device's small-signal AC performance in the TLC25M2CPWLE configuration, supporting bandwidth-critical signal conditioning up to ~50 kHz with adequate phase margin.
