Product details
Overview
TLC27M9CDRG4 from Texas Instruments is a precision quad operational amplifier featuring ±300 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 6 TΩ typical input impedance. It operates from 4 V to 16 V across −40°C to 85°C and is used in multiplexed data-acquisition systems requiring stable DC accuracy and low power.
For engineers reviewing the TLC27M9CDRG4 datasheet, TLC27M9CDRG4 pinout, TLC27M9CDRG4 application, or TLC27M9CDRG4 equivalent, this page delivers verified specifications, SOIC-14 package details, real-world use cases in test equipment and PLC analog I/O, and validated alternative options for design-in flexibility.
Technical Context
The TLC27M9CDRG4 implements LinCMOS™ process technology to achieve high input impedance and ultra-low bias currents while maintaining speed comparable to bipolar op-amps. Its trimmed offset voltage and low temperature coefficient enable precision DC-coupled signal conditioning without frequent recalibration.
It supports single-supply operation with common-mode input range extending to −0.2 V (below ground) and output swing to the negative rail-critical for sensor front-ends and industrial analog interfaces where ground-referenced signals dominate. The device is latch-up immune and includes ESD protection circuitry per JEDEC JESD22-A114.

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 |
|---|---|---|---|
| TLC27M4BCDR | Same SOIC-14 package; ±2 mV max offset (vs. ±0.3 mV for TLC27M9CDRG4); higher quiescent current (150 µA vs. 120 µA typ) | Suitable for less demanding DC accuracy requirements; lower cost in volume | Select when offset drift and noise are secondary to cost and availability |
| OPA2277UA/2K5 | SOIC-8 dual op-amp (not quad); ±10 µV max offset; 600 nA max Ib; 0.1 µV/°C drift; requires two units for quad function | Better DC performance but higher board area and BOM count; not drop-in | Choose only if ultra-low offset and drift outweigh layout complexity and cost penalties |
Compared with TLC27M4BCDR, the TLC27M9CDRG4 delivers 6.7× lower max offset and lower drift for high-accuracy sensor front-ends; versus OPA2277UA/2K5, it offers integrated quad functionality and lower power but trades off ultimate precision for integration and cost efficiency.

FAQ
What is the maximum operating temperature range for the TLC27M9CDRG4?
The TLC27M9CDRG4 is rated for operation from −40°C to +85°C. This industrial temperature grade is confirmed in Section 6.3 (Recommended Operating Conditions) and Table 4-1 of the official TI datasheet SLOS093E. The device maintains its specified offset voltage (±300 µV max), drift (±0.6 µV/°C), and supply current (120 µA typ) across this full range when powered from 4 V to 16 V.
Does the TLC27M9CDRG4 support rail-to-rail input operation?
No, the TLC27M9CDRG4 does not support rail-to-rail input. Its common-mode input voltage range extends to −0.2 V (below GND) and up to VDD − 1.5 V at 25°C with VDD = 5 V, as specified in Section 6.3. While the output swings to the negative rail (GND), the inputs cannot accept signals at the positive rail - limiting high-side sensing without level-shifting. This is distinct from true rail-to-rail input op-amps.
Is the TLC27M9CDRG4 pin-compatible with other TLC27Mxx variants in SOIC-14?
Yes, the TLC27M9CDRG4 is pin-compatible with all TLC27Mxx quad op-amps in the D (SOIC-14) package, including TLC27M4, TLC27M4A, TLC27M4B, and TLC27M9 variants. Pin configuration and functions are identical per Table 5-1 and Figure 5-1 in the datasheet. However, electrical performance (offset, drift, noise) differs by grade - substitution requires validation against system-level DC accuracy requirements.
What is the typical supply current for the TLC27M9CDRG4 at 25°C and 5 V?
The typical supply current for the TLC27M9CDRG4 is 120 µA per amplifier at 25°C and VDD = 5 V, as stated in Section 6.4 Electrical Characteristics. Since it is a quad amplifier, total IDD is approximately 480 µA under these conditions. This value is confirmed across multiple test conditions (Sections 6.4–6.9) and is stable across the industrial temperature range.
Can the TLC27M9CDRG4 drive a 10 kΩ load while maintaining specified accuracy?
Yes, the TLC27M9CDRG4 is characterized with RL = 10 kΩ in all key electrical tests (Sections 6.4–6.9), including input offset voltage, CMRR, and open-loop gain. Its output stage is designed to maintain full DC specifications into 10 kΩ loads. For heavier loads (<2 kΩ), output swing and distortion may degrade - consult Figures 6-5 through 6-12 for VOH/VOL vs. IOH/IOL curves.
