Texas Instruments TLC27M9ID

Overview

TLC27M9ID from Texas Instruments is a precision quad operational amplifier in SOIC-14 package, 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 - optimized for high-accuracy signal conditioning in industrial sensor interfaces.

For engineers reviewing the TLC27M9ID datasheet, TLC27M9ID pinout, TLC27M9ID application, or TLC27M9ID equivalent, this device supports low-power, wide-temperature (–40°C to +85°C), single-supply operation from 4 V to 16 V and delivers stable performance in multiplexed data acquisition and programmable logic controller analog I/O modules.

Technical Context

The TLC27M9ID uses LinCMOS™ process technology to combine CMOS input stage benefits - ultra-low bias current (<1 pA typ), high input impedance, and ESD protection - with bipolar-like speed and noise performance. Its architecture enables precision amplification without external trimming across extended temperature ranges.

It operates over –40°C to +85°C with supply voltages from 4 V to 16 V, supports common-mode input down to –0.2 V (beyond negative rail), and maintains low quiescent current (120 µA per two amplifiers at 25°C, 5 V) while delivering 0.5 V/µs slew rate and 1.1 MHz unity-gain bandwidth.

FAQ

What is the maximum operating temperature range for the TLC27M9ID?

The TLC27M9ID is rated for continuous operation from –40°C to +85°C, as confirmed by its "I" suffix designation and electrical characteristics tables covering that full range at 4 V to 16 V supply. Absolute maximum ratings extend to 150°C storage, but functional operation is guaranteed only within the –40°C to +85°C ambient range.

Does the TLC27M9ID support true single-supply operation with ground-referenced inputs?

Yes, the TLC27M9ID supports true single-supply operation: its common-mode input range extends to –0.2 V (below GND) at 5 V supply, and its output swings to within 50 mV of GND. This enables direct interfacing with 0 V–referenced sensors and ADCs without level-shifting circuitry.

How does the input offset voltage drift of the TLC27M9ID compare to standard precision op-amps?

The TLC27M9ID exhibits ±0.6 µV/°C typical offset drift over 25°C to 70°C - significantly lower than many general-purpose CMOS op-amps (often >2 µV/°C) and competitive with premium bipolar devices. This drift contributes <1.2 mV total error across its –40°C to +85°C operating range.

Can the TLC27M9ID drive capacitive loads directly, and what is its phase margin?

The TLC27M9ID has a phase margin of 60° at unity gain with 20 pF load and 10 kΩ source resistance, as specified in the operating characteristics table. It is stable driving moderate capacitive loads (≤100 pF) without isolation resistors, but larger loads require careful compensation per Figure 7-3 in the datasheet.

Is the TLC27M9ID pin-compatible with other devices in the TLC27Mxx family?

Yes, the TLC27M9ID shares identical SOIC-14 pinout and footprint with all TLC27Mxx variants (e.g., TLC27M4ID, TLC27M4AID), enabling direct substitution where offset voltage and drift requirements align. Pin functions are fully documented in Table 5-1 and Figure 5-1 of the datasheet.
