Product details
Overview
TLC27M9IDRG4 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 supports high-accuracy signal conditioning in multiplexed data acquisition and industrial analog I/O modules.
For engineers reviewing the TLC27M9IDRG4 datasheet, TLC27M9IDRG4 pinout, TLC27M9IDRG4 application, or TLC27M9IDRG4 equivalent, this page delivers verified specifications, SOIC-14 package details, real-world use cases in test equipment and motor control, and validated alternative options for design continuity.
Technical Context
The TLC27M9IDRG4 implements LinCMOS™ process technology to achieve ultra-low input bias current (±10 pA typ at 25°C) and high DC precision while maintaining speed comparable to bipolar op-amps. Its architecture supports single-supply operation with common-mode input range extending to −0.2 V below ground and output swing to the negative rail.
It delivers 1.1 MHz unity-gain bandwidth and 0.5 V/µs slew rate at 5 V supply, with CMRR ≥65 dB and PSRR ≥70 dB - enabling stable performance in noisy industrial environments where precision DC gain and rejection of supply and common-mode disturbances are critical.

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 |
|---|---|---|---|
| TLC27M4IDR | Higher max offset (±2 mV), same package and pinout - less precise but lower cost | Suitable for general-purpose industrial amplification where ±2 mV offset is acceptable | Select when budget constraints outweigh need for sub-mV DC accuracy |
| OPA2182IDR | Lower offset (±4 µV), zero-drift architecture, higher supply current (560 µA) - superior DC performance at higher power | Better for ultra-high-precision metrology; not drop-in due to different quiescent current and layout sensitivity | Choose when long-term stability and near-zero drift justify increased power and cost |
Compared with TLC27M4IDR, the TLC27M9IDRG4 offers 6.7× lower offset for demanding sensor interfaces; versus OPA2182IDR, it trades ultra-low drift for 4.7× lower supply current - making it optimal for multi-channel, power-constrained industrial systems.

FAQ
What is the maximum operating temperature range for the TLC27M9IDRG4?
The TLC27M9IDRG4 is rated for −40°C to +85°C free-air operating temperature. This I-suffix grade is qualified for industrial environments and supports reliable operation in programmable logic controllers, motor drives, and analog I/O modules exposed to wide ambient variations. Absolute maximum junction temperature remains 150°C per datasheet limits.
Does the TLC27M9IDRG4 support true single-supply operation?
Yes, the TLC27M9IDRG4 supports true single-supply operation: its input common-mode range extends to −0.2 V (below GND), and its output swings fully to the negative rail (GND). When powered from a single 5 V or 12 V supply with GND as reference, it can amplify ground-referenced signals without level-shifting circuitry - a key advantage in space-constrained industrial designs.
What is the typical supply current for the TLC27M9IDRG4 at 5 V?
The typical supply current for the TLC27M9IDRG4 is 120 µA per amplifier at 25°C and VDD = 5 V, totaling 480 µA for all four channels. This low quiescent current enables multi-amplifier configurations in battery-powered or thermally constrained applications such as portable test equipment and distributed sensor nodes.
Is the TLC27M9IDRG4 pin-compatible with other TLC27Mxx variants?
Yes, the TLC27M9IDRG4 is pin-compatible with all TLC27Mxx quad op-amps in SOIC-14 (D) package, including TLC27M4IDR, TLC27M4BIDR, and TLC27M4AIDR. All share identical pinout, footprint, and electrical interface - allowing direct substitution in existing layouts when upgrading offset performance or adjusting grade (C/I/M suffix).
What packaging and reel options are available for the TLC27M9IDRG4?
The TLC27M9IDRG4 is supplied in SOIC-14 (D) package, tape-and-reel format, with 2,500 units per reel. The 'G4' suffix denotes RoHS-compliant, green (halogen-free) packaging per TI's environmental standards. No PDIP or TSSOP variants exist for the TLC27M9I grade - only SOIC-14 is orderable for this specific temperature and offset specification.
