Product details
Overview
TLC27M2CPWLE from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, featuring 5 mV max input offset voltage at 25°C, rail-to-rail output swing down to negative rail, and operation from 3 V to 16 V supply across 0°C to 70°C. It delivers 0.40 V/µs slew rate, 32 nV/√Hz input noise at 1 kHz, and 525 kHz unity-gain bandwidth - enabling high-accuracy signal conditioning in low-power sensor front-ends and portable instrumentation.
For engineers reviewing the TLC27M2CPWLE datasheet, TLC27M2CPWLE pinout, TLC27M2CPWLE application, or TLC27M2CPWLE equivalent, this page provides verified package mapping (TSSOP-8), confirmed electrical parameters per TI SLOS051E Rev. August 2008, real-world application context for single-supply transducer interfacing, and validated alternative options with documented functional trade-offs.
Technical Context
The TLC27M2CPWLE implements a silicon-gate LinCMOS process architecture that achieves ultra-low input bias current (0.6 pA typ at 25°C) and high input impedance (10¹² Ω typ), enabling direct interfacing with high-impedance sources like piezoelectric sensors and pH electrodes. Its common-mode input range extends below the negative rail (−0.2 V min at VDD = 5 V), supporting true single-supply operation without level-shifting circuitry.
Internal ESD protection meets MIL-STD-883C Method 3015.2 (2000 V HBM), and latch-up immunity is designed-in per TI's LinCMOS process. The device exhibits stable phase margin (40° typ at 25°C) under unity-gain configuration with 20 pF load, confirming suitability for uncompensated buffer and gain-stage applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 5 mV max at 25°C - defines worst-case DC error in precision amplification chains before trimming |
| Supply Voltage Range | 3 V to 16 V - supports battery-powered (3.3 V/5 V) and industrial (12 V/15 V) rails without external regulation |
| Slew Rate | 0.40 V/µs typ at VDD = 5 V - enables faithful reproduction of ≤100 kHz small-signal waveforms |
| Unity-Gain Bandwidth | 525 kHz typ at VDD = 5 V - sets upper limit for stable closed-loop gain ≥1 configurations |
| Input Noise Density | 32 nV/√Hz at f = 1 kHz - determines minimum resolvable signal in low-frequency sensor interfaces |
| Common-Mode Input Range | −0.2 V to 3.5 V at VDD = 5 V - allows input signals below ground, critical for single-supply transducer biasing |
| Output Voltage Swing | 0 V to 3.9 V at VDD = 5 V (RL = 100 kΩ) - delivers full dynamic range into high-impedance loads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2CPWLE | Lower supply current (120 µA vs. 210 µA), higher VIO (10 mV max), same PW package | Optimized for ultra-low-power, lower-precision applications where battery life outweighs DC accuracy | Select when quiescent current <150 µA is mandatory and offset error ≤10 mV is acceptable |
| TLV2462IPW | Rail-to-rail I/O, 600 µV VIO max, 0.55 V/µs slew, but requires ≥2.7 V supply and has higher IQ (550 µA) | Higher precision and speed at cost of 2.6× higher supply current; not suitable for sub-3 V operation | Select when sub-millivolt offset and faster settling are required, and power budget permits ≥500 µA per amp |
Compared with TLC27L2CPWLE, the TLC27M2CPWLE trades 2× higher supply current for half the input offset voltage; versus TLV2462IPW, it offers 2.6× lower IQ and wider supply range but sacrifices 12× tighter offset spec and 38% higher slew rate.

FAQ
What is the maximum input offset voltage specification for TLC27M2CPWLE at 25°C?
The TLC27M2CPWLE has a maximum input offset voltage of 5 mV at 25°C, as specified in the "Electrical Characteristics" table of TI's SLOS051E datasheet (Rev. August 2008). This value applies across the full operating temperature range (0°C to 70°C) for the C-suffix grade, and is measured under standard test conditions (VO = 1.4 V, VIC = 0 V, VDD = 5 V).
Does TLC27M2CPWLE support true single-supply operation with inputs referenced to ground?
Yes, the TLC27M2CPWLE supports true single-supply operation with inputs referenced to ground. Its common-mode input voltage range extends to −0.2 V (minimum) at VDD = 5 V, allowing the inverting and non-inverting inputs to operate at or slightly below GND potential - eliminating the need for external level-shifting circuitry in grounded-sensor applications.
What is the supply current consumption of TLC27M2CPWLE at 25°C and VDD = 5 V?
The TLC27M2CPWLE draws 210 µA typical supply current per amplifier (420 µA total for both amplifiers) at 25°C and VDD = 5 V, with a maximum of 560 µA total across the 0°C to 70°C range. This low quiescent current enables multi-year battery operation in always-on sensing nodes.
Is TLC27M2CPWLE pin-compatible with other TSSOP-8 dual op-amps like LMV358 or TLV2462?
No, the TLC27M2CPWLE is not pin-compatible with LMV358 or TLV2462. While all three use TSSOP-8 packages, the pin assignments differ: TLC27M2CPWLE uses standard TI dual-op-amp pinout (1=Inv1, 2=NonInv1, 3=Out1, 4=GND, 5=VCC, 6=Inv2, 7=NonInv2, 8=Out2), whereas LMV358 and TLV2462 follow different conventions (e.g., VCC on pin 8, GND on pin 4). PCB layout must match the TLC27M2CPWLE-specific pinout.
What is the unity-gain bandwidth of TLC27M2CPWLE and how does it vary with supply voltage?
The TLC27M2CPWLE has a typical unity-gain bandwidth of 525 kHz at VDD = 5 V and 635 kHz at VDD = 10 V, as measured under standard conditions (VI = 10 mV, CL = 20 pF). Bandwidth increases with supply voltage due to higher internal bias currents, enabling improved small-signal response in higher-voltage industrial applications without changing external compensation.
