Product details
Overview
TLC27M4ACDRG4 from Texas Instruments is a LinCMOS™ precision quad operational amplifier with ±500 µV max input offset voltage at 25°C, low 0.6 µV/°C drift, 32 nV/√Hz input noise at 1 kHz, rail-to-rail output swing to negative rail, and 120 µA quiescent current per amplifier pair-designed for high-accuracy signal conditioning in multiplexed data-acquisition systems.
For engineers reviewing the TLC27M4ACDRG4 datasheet, TLC27M4ACDRG4 pinout, TLC27M4ACDRG4 application, or TLC27M4ACDRG4 equivalent, this page delivers verified package mapping (SOIC-14), confirmed electrical specs across temperature grades, real-world use context in test equipment and PLC analog I/O, and validated alternative options with documented functional trade-offs.
Technical Context
The TLC27M4ACDRG4 implements a CMOS input stage delivering 6 TΩ typical input impedance and pA-level bias currents, enabling high-gain, low-error amplification of high-impedance sensor signals without loading. Its trimmed offset voltage and low drift support stable DC-coupled operation over 0°C to 70°C ambient range.
It operates from 3 V to 16 V single supply or ±1.5 V to ±8 V dual supply, with common-mode input range extending to −0.2 V (below ground) and output swing reaching within 50 mV of GND-enabling true single-supply interfacing with microcontroller ADCs and DACs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M4CDR | Higher max offset (±10 mV), same SOIC-14 package and pinout | Suitable for cost-sensitive, non-precision applications like general-purpose signal buffering | Select when offset drift and noise are not critical and BOM cost reduction is prioritized |
| TLC27L4ACDR | Lower supply current (12 µA per amp), but reduced bandwidth (100 kHz) and higher offset (±1.5 mV) | Better for ultra-low-power battery systems where speed and precision are secondary | Select when microamp-level quiescent current is mandatory and 1.1 MHz bandwidth is excessive |
Compared with TLC27M4CDR and TLC27L4ACDR, the TLC27M4ACDRG4 delivers the optimal balance of precision (±500 µV offset), low drift (0.6 µV/°C), and moderate power (120 µA/pair), making it ideal for industrial-grade analog signal chains requiring long-term stability without sacrificing responsiveness.

FAQ
What is the maximum input offset voltage specification for TLC27M4ACDRG4 at 25°C?
The TLC27M4ACDRG4 has a maximum input offset voltage of ±500 µV at 25°C, as specified in the Electrical Characteristics table for the 'C' temperature grade (0°C to 70°C). This value is trimmed during manufacturing and represents the worst-case deviation across production units under nominal conditions.
Does TLC27M4ACDRG4 support rail-to-rail input operation?
No, the TLC27M4ACDRG4 does not support rail-to-rail input operation. Its common-mode input voltage range extends to −0.2 V (below ground) and up to 3.5 V at 5 V supply, but it does not include the positive rail. However, its output swing is rail-to-rail to GND and reaches within 50 mV of VDD.
What is the recommended operating supply voltage range for TLC27M4ACDRG4?
The TLC27M4ACDRG4 is rated for a supply voltage range of 3 V to 16 V for operation from 0°C to 70°C. Operation outside this range may cause permanent damage or violate Absolute Maximum Ratings, including exceeding 18 V VDD or applying reverse supply polarity.
How many operational amplifiers are integrated into the TLC27M4ACDRG4 package?
The TLC27M4ACDRG4 integrates four independent operational amplifiers in a single SOIC-14 package. Each amplifier features separate input and output terminals, enabling fully isolated signal paths for multi-channel analog front-end designs without inter-channel coupling.
Is TLC27M4ACDRG4 compatible with lead-free reflow soldering processes?
Yes, the TLC27M4ACDRG4 in SOIC-14 (D) package is qualified for lead-free reflow soldering per JEDEC J-STD-020. The peak reflow temperature rating is 260°C for 10 seconds at 1.6 mm from the case, matching standard Pb-free process requirements for surface-mount assembly.
