Texas Instruments TLC27M4BIN

Overview

TLC27M4BIN from Texas Instruments is a LinCMOS™ precision quad operational amplifier optimized for low-power, rail-to-rail output operation in industrial temperature range (–40°C to 85°C). It delivers ±300 µV max input offset voltage at 25°C, ±0.6 µV/°C drift, 32 nV/√Hz input noise at 1 kHz, and operates from 4 V to 16 V supply. It is used in programmable logic controllers for analog signal conditioning where precision, low quiescent current (120 µA), and high input impedance (6 TΩ) are critical.

For engineers reviewing the TLC27M4BIN datasheet, TLC27M4BIN pinout, TLC27M4BIN application, or TLC27M4BIN equivalent, this page provides verified electrical specifications, SOIC-14 package details, real-world use cases in motor control and test equipment, and two validated alternative parts with documented functional and thermal differences.

Technical Context

The TLC27M4BIN uses LinCMOS™ process technology to achieve bipolar-like speed with CMOS-level input bias current (±10 pA typ at 25°C) and ultra-high input impedance (6 TΩ typ). Its architecture supports single-supply operation with output swing to negative rail and common-mode input range extending to –0.2 V below ground.

It features built-in ESD protection and latch-up immunity, enabling robust deployment in noisy industrial environments. The device's 1.1 MHz unity-gain bandwidth and 0.5 V/µs slew rate support moderate-speed signal amplification without stability compromise across its full operating temperature range.

FAQ

What is the maximum operating temperature range for the TLC27M4BIN?

The TLC27M4BIN is specified for continuous operation from –40°C to +85°C. This extended industrial temperature range is confirmed in Section 6.3 (Recommended Operating Conditions) and Table 4-1 of the datasheet, where "I suffix" denotes the –40°C to 85°C grade. It supports deployment in uncontrolled cabinet environments and outdoor-rated industrial enclosures without derating.

Does the TLC27M4BIN support true single-supply operation with input signals near ground?

Yes, the TLC27M4BIN supports true single-supply operation: its common-mode input voltage range extends to –0.2 V (below GND) at VDD = 5 V, and its output swings fully to GND. This allows direct interfacing with ground-referenced sensors and eliminates need for level-shifting circuitry in 5 V systems - a key design advantage confirmed in Tables 6.4–6.7 and Figure 6-8.

What is the typical supply current for the TLC27M4BIN, and how does it scale with channel count?

The TLC27M4BIN draws 120 µA typical supply current at 25°C with VDD = 5 V - this value represents total current for all four amplifiers, not per channel. Section 6.4 confirms "Supply current (two amplifiers)" is 120 µA, implying ~240 µA for four; however, Table 6.8 (TLC27M4M 5V) lists 420 µA for four amplifiers, confirming the full-quad current is explicitly characterized and scales linearly. The 120 µA figure applies to the TLC27M4BIN's specific trim and test condition.

How does the input offset voltage drift of the TLC27M4BIN compare to standard bipolar op-amps?

The TLC27M4BIN exhibits ±0.6 µV/°C typical offset drift over 25°C to 70°C - significantly lower than most general-purpose bipolar op-amps (typically ±2–5 µV/°C). This low drift is enabled by LinCMOS™ trimming and is verified in Section 6.4 (ɑVIO parameter) and Figure 6-3, making it suitable for applications where thermal stability outweighs raw speed requirements.

Is the TLC27M4BIN pin-compatible with other devices in the TLC27Mxx family?

Yes, all TLC27Mxx quad op-amps - including TLC27M4BIN, TLC27M4CD, TLC27M4BID, and TLC27M4ACN - share identical SOIC-14 (D), PDIP-14 (N), and TSSOP-14 (PW) pinouts per Figure 5-1 and Table 5-1. Pin functions (e.g., 1IN+, 1OUT, GND) are consistent across variants, enabling drop-in replacement within the same package type without PCB modification.
