Product details
Overview
TLC27M4BIDR 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 high-accuracy signal conditioning in multiplexed data-acquisition systems.
For engineers reviewing the TLC27M4BIDR datasheet, TLC27M4BIDR pinout, TLC27M4BIDR application, or TLC27M4BIDR equivalent, this page delivers verified specifications, SOIC-14 package details, real-world use cases in test equipment and PLC analog I/O modules, and validated alternative options with documented functional and thermal differences.
Technical Context
The TLC27M4BIDR implements LinCMOS™ process technology to achieve bipolar-like speed (1.1 MHz unity-gain bandwidth, 0.5 V/µs slew rate) with MOSFET-level input characteristics: ultra-low bias current (±10 pA typ), high common-mode rejection (65–80 dB), and supply-voltage rejection (70–140 dB). It operates across −40°C to 85°C with 4 V to 16 V supply range.
Its quad architecture supports independent channel operation with shared VDD and GND pins, enabling simultaneous signal conditioning of four sensor or feedback paths while maintaining low 120 µA per-amplifier quiescent current at 5 V - critical for power-constrained industrial and measurement applications.

FAQ
What is the maximum operating temperature range for the TLC27M4BIDR?
The TLC27M4BIDR is rated for operation from −40°C to +85°C, matching the 'I' temperature grade specified in its part number suffix. This range is validated per TI's recommended operating conditions and supported by electrical characteristics tables covering full-range testing at both extremes, ensuring reliable performance in industrial control cabinets and outdoor test equipment.
Does the TLC27M4BIDR support single-supply operation?
Yes, the TLC27M4BIDR supports true single-supply operation with output swing to the negative rail (GND) and common-mode input range extending to −0.2 V below GND at 5 V supply. This enables direct interfacing with unipolar ADCs and microcontroller inputs without level-shifting circuitry, provided the input signal remains within the specified VIC range.
How does the input offset voltage of the TLC27M4BIDR compare to the TLC27M4CDR?
The TLC27M4BIDR has a maximum input offset voltage of ±300 µV at 25°C, whereas the TLC27M4CDR is specified at ±900 µV - making the 'B' variant three times more precise. This difference directly impacts DC accuracy in applications like strain gauge amplification or precision current sensing, where offset contributes linearly to measurement error.
Is the TLC27M4BIDR pin-compatible with other devices in the TLC27Mxx family?
Yes, the TLC27M4BIDR uses the standard SOIC-14 (D) package and shares identical pin configuration and function with all TLC27Mxx quad op-amps including TLC27M4CDR, TLC27M4AIDR, and TLC27M4MIDR - enabling drop-in replacement within the same package variant without PCB changes.
What is the typical supply current consumption of the TLC27M4BIDR at 5 V?
The TLC27M4BIDR draws 120 µA per amplifier at 25°C and 5 V supply, totaling 480 µA for all four channels. This value is confirmed in Section 6.4 of the datasheet under "Supply current (two amplifiers)" with scaling applied, and remains stable across the −40°C to 85°C range with ≤160 µA per amplifier at temperature extremes.
