Texas Instruments TLC27M4BCD

Overview

TLC27M4BCD 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 - optimized for low-power, high-accuracy signal conditioning in multiplexed data acquisition and test equipment.

For engineers reviewing the TLC27M4BCD datasheet, TLC27M4BCD pinout, TLC27M4BCD application, or TLC27M4BCD equivalent, this device supports stable operation from 4 V to 16 V across −40°C to +85°C, delivers 1.1 MHz unity-gain bandwidth, and enables precision analog front-ends where low quiescent current (120 µA per two amplifiers) and ESD-protected inputs are critical.

Technical Context

The TLC27M4BCD uses LinCMOS™ process technology to achieve bipolar-like speed with MOSFET-level input impedance and ultra-low bias currents. 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, enabling true ground-referenced sensing without level-shifting circuitry.

It integrates latch-up immunity and on-chip ESD protection, and its trimmed offset voltage grade (B) targets applications requiring tighter DC accuracy than standard-grade variants while maintaining compatibility with SOIC-14 footprint and thermal dissipation characteristics (950 mW at 25°C).

FAQ

What is the maximum operating temperature range for the TLC27M4BCD?

The TLC27M4BCD is rated for operation from −40°C to +85°C. This extended industrial temperature range ensures reliable performance in programmable logic controllers, motor drive control modules, and field-deployed test equipment exposed to ambient thermal stress. The device maintains specified offset voltage, bandwidth, and output swing across this full range.

Does the TLC27M4BCD support single-supply operation with rail-to-rail output?

Yes, the TLC27M4BCD supports true single-supply operation with output swing to the negative rail (GND). Its common-mode input range extends to −0.2 V, and output can drive to within 50 mV of GND under load - enabling direct interfacing with unipolar ADCs and eliminating the need for dual supplies in sensor front-ends.

How does the input offset voltage of TLC27M4BCD compare to other variants in the TLC27M4 family?

The TLC27M4BCD has a maximum input offset voltage of ±300 µV at 25°C - tighter than the TLC27M4ACD (±500 µV) and significantly tighter than the standard TLC27M4CD (±10 mV). This B-grade trim makes TLC27M4BCD the most accurate variant for applications demanding minimal DC error without external calibration.

What is the typical supply current consumption of the TLC27M4BCD at 5 V?

At VDD = 5 V and 25°C, the TLC27M4BCD draws 120 µA per two amplifiers - totaling 240 µA for all four op-amps. This ultra-low quiescent current enables energy-efficient designs in battery-powered data loggers and portable instrumentation where standby power must be minimized.

Is the TLC27M4BCD pin-compatible with other SOIC-14 quad op-amps?

Yes, the TLC27M4BCD uses the industry-standard SOIC-14 (D) package with 1.27 mm pitch and matches the pinout of other TLC27M4 variants (e.g., TLC27M4ACD, TLC27M4CD) and compatible TI quad op-amps like TL074 and TLC2274 - allowing drop-in replacement in existing layouts when upgrading to higher precision or lower power.
