Product details
Overview
TLC27M4IDG4 from Texas Instruments is a LinCMOS™ precision quad operational amplifier optimized for low-power, high-input-impedance analog signal conditioning in industrial and test equipment. It delivers ±300 µV max input offset voltage at 25°C, ±0.6 µV/°C drift, 32 nV/√Hz input noise at 1 kHz, rail-to-rail output swing to negative rail, and operates from 4 V to 16 V across −40°C to 85°C.
For engineers reviewing the TLC27M4IDG4 datasheet, TLC27M4IDG4 pinout, TLC27M4IDG4 application, or TLC27M4IDG4 equivalent, key selection criteria include input offset stability over temperature, ultra-low quiescent current (120 µA per two amplifiers), high common-mode input range, and SOIC-14 package compatibility with legacy analog designs requiring precision and power efficiency.
Technical Context
The TLC27M4IDG4 implements a CMOS input stage with 6 TΩ typical input impedance and ESD protection, enabling direct interfacing with high-impedance sensors without loading. Its trimmed offset voltage and low drift support stable DC-coupled gain stages in multiplexed data acquisition systems where thermal drift must be minimized.
It features internal phase compensation for unity-gain stability, 1.1 MHz unity-gain bandwidth (at 5 V), 0.5 V/µs slew rate, and operates reliably under single-supply conditions with common-mode input range extending to the negative rail - critical for ground-referenced sensor front-ends and programmable logic controller analog I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±300 µV max at 25°C, VDD = 5 V - enables accurate DC amplification without frequent nulling in precision instrumentation |
| Offset Drift | ±0.6 µV/°C - ensures <1.8 µV total drift over 0–30°C ambient change, reducing calibration frequency |
| Supply Current | 120 µA per two amplifiers at 25°C - supports battery-powered or energy-constrained systems with four independent op-amps |
| Input Impedance | 6 TΩ typ - preserves signal integrity from high-Z sources like piezoelectric sensors or pH electrodes |
| Noise Density | 32 nV/√Hz at 1 kHz - suitable for low-level signal amplification in test equipment without dominant op-amp noise contribution |
| Common-Mode Range | −0.2 V to 3.5 V (VDD = 5 V) - allows input signals down to 200 mV below ground, supporting true single-supply operation |
| Output Swing | Includes negative rail - eliminates need for dual supplies in level-shifting or sensor biasing circuits |

Applications
| Test and Measurement Equipment | Multiplexed Data-Acquisition Systems |
|---|---|
Use Scenario: Precision front-end amplification in benchtop multimeters and automated test equipment (ATE) requiring stable DC gain over temperature. IC Role / Device Role / Timing Role: Quad op-amp provides independent gain/offset stages for voltage, current, and resistance measurement channels. Use Value: ±300 µV offset and ±0.6 µV/°C drift minimize calibration drift, extending recalibration intervals by up to 3× versus standard op-amps. | Use Scenario: Signal conditioning for 16-channel industrial DAQ modules with shared microcontroller and sequential sampling. IC Role / Device Role / Timing Role: Four parallel amplifiers condition sensor inputs (thermocouples, strain gauges) before multiplexing to a single ADC. Use Value: 120 µA per two amplifiers enables full quad operation at <250 µA total, reducing thermal load and power supply burden. |
| Programmable Logic Controllers | Analog Input/Output Modules |
Use Scenario: Analog signal processing in PLC backplanes where space, power, and long-term stability are constrained. IC Role / Device Role / Timing Role: Configured as differential receivers, active filters, and output drivers for 4–20 mA loop interfaces. Use Value: 6 TΩ input impedance prevents loading of high-impedance field transmitters; rail-to-rail output drives 4–20 mA DAC references directly. | Use Scenario: Modular I/O cards for distributed control systems requiring four independent analog input channels. IC Role / Device Role / Timing Role: Each amplifier handles one channel's gain, filtering, and level-shifting prior to ADC conversion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M4CDR | Same die, C-temp grade (0°C to 70°C); 10 mV max VIO vs TLC27M4IDG4's 300 µV | Lower precision, lower cost; suitable for non-critical consumer or lab-grade instruments | Select when ambient operating range is limited to 0–70°C and offset stability is less critical than cost |
| TLC27M4BIDR | Same I-temp grade (−40°C to 85°C), but 2 mV max VIO and ±1.5 µV/°C drift vs TLC27M4IDG4's ±300 µV / ±0.6 µV/°C | Higher offset and drift; acceptable for AC-coupled or moderate-accuracy sensor interfaces | Choose when tighter offset spec is unnecessary and broader supply range (3–16 V at 0–70°C) is prioritized |
Compared with TLC27M4CDR and TLC27M4BIDR, the TLC27M4IDG4 offers superior DC precision (10× lower offset, 2.5× lower drift) and guaranteed performance across industrial temperature range, making it optimal for high-accuracy, thermally demanding applications where long-term calibration stability is essential.

FAQ
What is the maximum operating temperature range for the TLC27M4IDG4?
The TLC27M4IDG4 is rated for operation from −40°C to +85°C (I-temp grade), with guaranteed electrical performance across this full range, including input offset voltage ≤±300 µV and drift ≤±0.6 µV/°C at 25°C. Absolute maximum junction temperature is 150°C, but sustained operation above 125°C requires derating per datasheet dissipation ratings.
Does the TLC27M4IDG4 support single-supply operation?
Yes, the TLC27M4IDG4 supports true single-supply operation: its common-mode input voltage range extends to −0.2 V (200 mV below ground) and output swings to the negative rail. With VDD = 5 V and GND = 0 V, it accepts inputs from −0.2 V to 3.5 V and delivers outputs from 0 V to 4.95 V - ideal for ground-referenced sensor interfaces without dual supplies.
What is the supply current consumption of the TLC27M4IDG4?
The TLC27M4IDG4 draws 120 µA per two amplifiers at 25°C and VDD = 5 V, totaling 240 µA for all four op-amps. This ultra-low quiescent current enables use in battery-powered portable test gear and energy-sensitive industrial nodes while maintaining precision performance - significantly lower than bipolar quad op-amps with comparable offset specs.
Is the TLC27M4IDG4 pin-compatible with other TLC27Mxx variants?
Yes, the TLC27M4IDG4 is pin-compatible with all TLC27Mxx quad op-amps in SOIC-14 (D) package, including TLC27M4CDR, TLC27M4AIDR, and TLC27M4BIDR. Pin functions, footprint, and solder pad layout are identical - allowing direct substitution in existing designs when upgrading precision or temperature grade without PCB revision.
What packaging and ordering options are available for the TLC27M4IDG4?
The TLC27M4IDG4 is supplied in SOIC-14 (D) package, tape-and-reel format (suffix R), with orderable part number TLC27M4IDR. The "DG4" suffix denotes the SOIC-14 package variant per TI's packaging nomenclature; it is not a separate device but the industry-standard marking for this D-package configuration of the TLC27M4I grade.
