Product details
Overview
TLC27L2CP from Texas Instruments is a precision dual CMOS operational amplifier in an 8-pin PDIP package, featuring 10 mV max input offset voltage (25°C), ultra-low 34 µA typical supply current at 5 V, and rail-to-rail output swing down to the negative rail. It operates from 3 V to 16 V over 0°C to 70°C and supports single-supply sensor signal conditioning in battery-powered field transmitters.
For engineers reviewing the TLC27L2CP datasheet, TLC27L2CP pinout, TLC27L2CP application, or TLC27L2CP equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in industrial sensing, and two confirmed alternative parts with documented functional and thermal differences.
Technical Context
The TLC27L2CP uses Texas Instruments' LinCMOS™ silicon-gate process to achieve 10¹² Ω typical input impedance and sub-60 pA input bias current at 25°C, enabling high-impedance sensor interfacing without loading. Its common-mode input range extends 0.2 V below ground, supporting true single-supply operation with inputs referenced to GND.
It delivers 85 kHz unity-gain bandwidth and 0.03 V/µs slew rate at 5 V, optimized for low-frequency precision amplification-not high-speed signal processing. Phase margin remains ≥34° across temperature, ensuring stable operation with capacitive loads up to 20 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 10 mV at 25°C - sets DC error floor in precision gain stages and reference buffers |
| Supply Current (typ) | 34 µA at 5 V - enables multi-year operation on coin-cell batteries in remote sensors |
| Input Impedance (typ) | 10¹² Ω - preserves signal integrity from high-Z sources like pH electrodes or piezoresistive bridges |
| Common-Mode Range | −0.2 V to 3.5 V at 5 V - allows direct interface to 0–5 V sensor outputs without level-shifting |
| Output Swing (low) | 1 mV above GND at 5 V - supports full-scale analog-to-digital conversion in single-supply systems |
| Unity-Gain Bandwidth | 85 kHz at 5 V - sufficient for <10 kHz sensor signals including pressure, temperature, and flow transmitters |
| ESD Rating | 2000 V HBM - meets MIL-STD-883C Method 3015.2 for robust handling in manufacturing environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2CDR | SOIC-8 package; identical electrical specs but surface-mount; 0.5°C/W lower θJA than PDIP | Required for automated SMT assembly; unsuitable for hand-soldered prototyping or socketed test fixtures | Select TLC27L2CDR when volume production, PCB space constraints, or thermal performance in compact enclosures are priorities. |
| TLV2462CP | Higher drive strength (15 mA short-circuit), 6.5 V/µs slew rate, 2.7–6 V supply range; 2.5 mV VIO max | Better suited for driving 50 Ω cables or low-impedance filters; not rated for 16 V operation or extended temperature ranges | Choose TLV2462CP only for low-voltage (<6 V), higher-speed applications where rail-to-rail I/O and tighter VIO are needed. |
Compared with TLC27L2CP, TLC27L2CDR offers identical precision and ultra-low power in a smaller footprint for production, while TLV2462CP trades supply voltage range and quiescent current for speed and output drive-making it incompatible for 12–16 V battery or industrial bus-powered designs.

FAQ
What is the maximum supply voltage rating for the TLC27L2CP?
The TLC27L2CP has an absolute maximum supply voltage of 18 V, but its recommended operating range is 3 V to 16 V across 0°C to 70°C. Operating beyond 16 V risks exceeding dissipation limits and degrading long-term reliability-even if within absolute ratings.
Does the TLC27L2CP support true rail-to-rail input operation?
No-the TLC27L2CP supports rail-to-rail *output* swing (down to GND and up to ~0.9 V below VDD), but its common-mode input range extends only to −0.2 V below GND and up to 3.5 V at 5 V supply. It does not accept inputs at the positive rail.
Can the TLC27L2CP be used in a single-supply 3.3 V system?
Yes-the TLC27L2CP is fully specified down to 3 V supply and operates across 0°C to 70°C at that voltage. At 3.3 V, output swing remains functional (VOL ≈ 1 mV, VOH ≈ 2.4 V), and input common-mode range adjusts to −0.2 V to ~2.2 V, accommodating most 3.3 V sensor interfaces.
How does the input offset voltage drift of the TLC27L2CP compare to bipolar op amps?
The TLC27L2CP exhibits typically 0.1 μV/month input offset voltage drift-including the first 30 days-due to its LinCMOS™ process. This is up to 100× better than typical bipolar op amps (e.g., LM358: ~1–2 μV/°C drift), making it superior for applications requiring months-long calibration stability.
Is the TLC27L2CP pin-compatible with other devices in the TLC27Lx family?
Yes-all TLC27Lx dual op amps (TLC27L2, TLC27L2A, TLC27L2B, TLC27L7) share identical 8-pin PDIP, SOIC, SOP, and TSSOP pinouts. The TLC27L2CP can be substituted with TLC27L2AC or TLC27L2BC in the same footprint, provided the system accommodates their tighter offset voltage specs and identical thermal behavior.
