Product details
Overview
TLC27L2CPG4 from Texas Instruments is a precision dual CMOS operational amplifier optimized for ultra-low-power, single-supply operation in sensor signal conditioning and industrial monitoring systems. It delivers 10 mV max input offset voltage (25°C), 95 μW typical power consumption at 5 V, and rail-to-rail output swing with common-mode input range extending below ground. Used in battery-powered field transmitters and smoke detectors.
For engineers reviewing the TLC27L2CPG4 datasheet, TLC27L2CPG4 pinout, TLC27L2CPG4 application, or TLC27L2CPG4 equivalent, key selection criteria include input offset voltage grade (C-suffix, 0°C to 70°C), PDIP-8 package compatibility, LinCMOS™ input impedance (>10¹² Ω), and low-voltage single-supply capability (3–16 V).
Technical Context
The TLC27L2CPG4 employs Texas Instruments' silicon-gate LinCMOS™ process, enabling high DC precision with exceptional input offset voltage stability (<0.1 μV/month drift) and ultra-low input bias current (≤60 pA typ). Its architecture supports true single-supply operation with common-mode input voltage down to −0.2 V (at VDD = 5 V) and output swing to negative rail.
Designed for precision analog front-ends, it features 85 kHz unity-gain bandwidth, 0.03 V/μs slew rate (VDD = 5 V), and robust ESD protection (2000 V HBM). The device maintains stable phase margin (≥34°) and large-signal gain (≥50 V/mV) across its full operating temperature range (0°C to 70°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIO max | 10 mV at 25°C - defines worst-case DC error in precision gain stages or reference buffers |
| Supply voltage | 3 V to 16 V - enables direct interface with 3.3 V, 5 V, and 12 V systems without level-shifting |
| IDD (typ) | 34 μA at 25°C - supports >10-year battery life in remote sensor nodes (e.g., 250 μA/hour avg) |
| Input impedance | 10¹² Ω typ - prevents loading of high-impedance sources like thermistors or pH electrodes |
| Common-mode range | −0.2 V to 3.5 V (VDD = 5 V) - allows direct sensing of signals referenced to ground or negative offsets |
| Output swing | Includes negative rail - simplifies single-supply design by eliminating need for dual supplies or charge pumps |
| ESD rating | 2000 V HBM - meets MIL-STD-883C requirements for handling in production and field environments |
Pinout & Package
Package: PDIP-8 (Plastic Dual In-line Package, 0.300-inch width), through-hole mount, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+ | Noninverting input, channel 1 | High-impedance node for differential sensing or reference voltage injection |
| 1IN− | Inverting input, channel 1 | Feedback path connection point; sets closed-loop gain and stability |
| 1OUT | Output, channel 1 | Drives loads up to ±30 mA; swings to negative rail for true single-supply operation |
| GND | Ground / negative supply | Reference return for both channels; must be low-impedance to minimize noise coupling |
| 2IN+ | Noninverting input, channel 2 | Independent high-Z input for second sensor or signal path |
| 2IN− | Inverting input, channel 2 | Separate feedback node enabling dual-channel instrumentation or filtering |
| 2OUT | Output, channel 2 | Independent output with same rail-to-rail capability as channel 1 |
| VDD | Positive supply | Single positive rail (3–16 V); powers both amplifiers and defines output voltage ceiling |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power | 95 μW at 5 V - enables continuous operation in energy-constrained IoT edge nodes |
| Latch-up immunity | Designed-in - eliminates risk of destructive latch-up during overvoltage or hot-plug events |
| Input offset drift | 0.1 μV/month - ensures long-term calibration stability in field-deployed instrumentation |
| Rail-to-rail output | Swings to negative rail - preserves full dynamic range in single-supply configurations |

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; rated for same 0°C to 70°C range | Suitable for surface-mount PCBs requiring smaller footprint and automated assembly | Select when board space or reflow compatibility is prioritized over through-hole serviceability |
| LMV358IDR | Higher supply current (80 μA typ), wider unity-gain bandwidth (1 MHz), but higher VIO (3 mV max) | Better for higher-speed AC-coupled applications; less suitable for ultra-low-drift DC sensing | Choose for cost-sensitive, moderate-precision designs where speed outweighs long-term offset stability |
Compared with TLC27L2CPG4, TLC27L2CDR offers identical performance in a compact SOIC package for SMT lines, while LMV358IDR trades ultra-low power and offset stability for higher bandwidth-making it appropriate for general-purpose signal conditioning but not for high-accuracy, battery-operated sensor nodes.

FAQ
What is the maximum operating temperature range for the TLC27L2CPG4?
The TLC27L2CPG4 is characterized for operation from 0°C to +70°C (C-suffix grade). Its absolute maximum junction temperature is 150°C, but functional operation is guaranteed only within the specified 0°C to 70°C free-air temperature range per the datasheet's Recommended Operating Conditions table.
Does the TLC27L2CPG4 support true single-supply operation with inputs below ground?
Yes. The TLC27L2CPG4 supports common-mode input voltages down to −0.2 V (at VDD = 5 V), allowing inputs referenced slightly below ground-critical for interfacing with grounded sensor bridges or thermocouples without level-shifting circuitry.
What is the typical supply current draw of the TLC27L2CPG4 at 5 V?
The TLC27L2CPG4 draws 34 μA typical supply current (two amplifiers) at 25°C and VDD = 5 V, corresponding to ~95 μW total power dissipation-enabling multi-year operation in coin-cell–powered wireless sensor nodes.
Is the TLC27L2CPG4 pin-compatible with other TLC27Lx variants in PDIP-8?
Yes. All TLC27Lx devices in the PDIP-8 (P) package-including TLC27L2CPG4, TLC27L2APG4, and TLC27L2BPG4-share identical pinout and footprint. Only the input offset voltage grade differs; no PCB redesign is needed when upgrading within the same package.
What packaging and compliance information applies to the TLC27L2CPG4?
The TLC27L2CPG4 is supplied in an 8-pin PDIP package with lead finish compliant with RoHS Directive 2011/65/EU. It is not halogen-free per TI's material declarations, and moisture sensitivity level (MSL) is not applicable due to its through-hole construction.
