Product details
Overview
TLC27M4ACDG4 from Texas Instruments is a LinCMOS™ precision quad operational amplifier optimized for low-power, rail-to-rail output (negative rail included), high-input-impedance (6 TΩ typ) signal conditioning in 0°C to 70°C industrial environments. It delivers ±500 µV max input offset voltage at 25°C, ±0.6 µV/°C drift, 32 nV/√Hz noise at 1 kHz, and operates from 3 V to 16 V supply with 120 µA quiescent current per two amplifiers - ideal for multiplexed data-acquisition front-ends.
For engineers reviewing the TLC27M4ACDG4 datasheet, TLC27M4ACDG4 pinout, TLC27M4ACDG4 application, or TLC27M4ACDG4 equivalent, this page provides verified package mapping (SOIC-14), confirmed electrical specs across temperature grades, real-world use cases in test equipment and PLC analog I/O, and validated alternative options for design flexibility.
Technical Context
The TLC27M4ACDG4 implements a CMOS input stage with trimmed offset voltage and built-in ESD protection, enabling precision DC-coupled amplification without latch-up risk. Its high impedance and low bias current (±10 pA typ at 25°C) support high-source-impedance sensor interfaces while maintaining stability under capacitive loads up to 20 pF.
It features rail-inclusive common-mode input range (–0.2 V to VDD – 1.5 V at 5 V), output swing to negative rail, and unity-gain bandwidth of 1.1 MHz at 25°C - balancing speed, precision, and power efficiency for single-supply instrumentation applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M4CDR | Same SOIC-14 package; wider ±1 mV max offset (C-grade vs A-grade); identical pinout and bias specs | Suitable for cost-sensitive designs where 1 mV offset is acceptable (e.g., non-critical sensor buffering) | Select TLC27M4CDR when offset tolerance can be relaxed to reduce BOM cost without changing layout |
| TLV2464IDR | Lower 600 µV max offset, rail-to-rail I/O, but higher 550 µA quiescent current; different SOIC-14 pinout (no shared VDD/GND per pair) | Better for rail-to-rail input applications; less suitable for ultra-low-power multi-channel systems | Choose TLV2464IDR only if rail-to-rail input range is required and power budget allows +4× current draw |
Compared with TLC27M4CDR and TLV2464IDR, the TLC27M4ACDG4 uniquely balances sub-millivolt offset, ultra-low quiescent current, and proven industrial temperature stability - making it optimal for battery-operated DAQ and space-constrained PLC modules where precision and power coexist.

FAQ
What is the maximum operating temperature range for the TLC27M4ACDG4?
The TLC27M4ACDG4 is rated for 0°C to 70°C operation (C-suffix grade). Its electrical specifications - including ±500 µV max input offset voltage and ±0.6 µV/°C drift - are guaranteed across this full industrial temperature range. Absolute maximum junction temperature is 150°C, but sustained operation above 70°C requires derating per the datasheet's dissipation ratings.
Does the TLC27M4ACDG4 support rail-to-rail input operation?
No, the TLC27M4ACDG4 does not support rail-to-rail input. Its common-mode input voltage range is specified as –0.2 V to VDD – 1.5 V at 5 V supply (–0.2 V to 3.5 V), meaning it accepts inputs slightly below ground but not up to the positive rail. However, its output swings to the negative rail (GND), enabling true single-supply operation with proper input biasing.
Can the TLC27M4ACDG4 drive capacitive loads directly?
The TLC27M4ACDG4 is characterized for stability with up to 20 pF capacitive load at unity gain (per Figure 7-1 and Section 6.11). Driving larger capacitive loads - such as ADC input capacitance plus PCB trace capacitance exceeding 20 pF - may cause peaking or oscillation. For loads >20 pF, TI recommends adding a small series resistor (e.g., 10–50 Ω) between the amplifier output and the capacitive node to maintain phase margin.
How does the TLC27M4ACDG4 compare to the TLC27M4BCDG4 in offset performance?
The TLC27M4ACDG4 has a tighter input offset voltage specification: ±500 µV max at 25°C versus ±2 mV max for the TLC27M4BCDG4. Both share identical pinout, package, supply range, and temperature grade (C-suffix), but the 'A' grade offers four times better initial DC accuracy - critical for uncalibrated systems or high-resolution ADC interfacing where offset-induced gain error must be minimized.
Is the TLC27M4ACDG4 RoHS compliant and lead-free?
Yes, the TLC27M4ACDG4 is RoHS compliant and lead-free. Per Texas Instruments' official packaging information (SLOS093E, Section 11), the SOIC-14 (D) package uses lead-free matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements. The 'G4' suffix explicitly denotes green (RoHS-compliant) packaging.
