Texas Instruments TLC27L4BIDRG4

Overview

TLC27L4BIDRG4 from Texas Instruments is a precision quad CMOS operational amplifier optimized for low-power, single-supply operation in sensor signal conditioning and industrial monitoring systems. It delivers 2 mV max input offset voltage at 25°C, ultra-low 195 µW typical power consumption at 5 V, and rail-to-rail output swing with common-mode input range extending below ground. Used in battery-powered field transmitters and smoke detectors where long-term offset stability and micropower operation are critical.

For engineers reviewing the TLC27L4BIDRG4 datasheet, TLC27L4BIDRG4 pinout, TLC27L4BIDRG4 application, or TLC27L4BIDRG4 equivalent, key selection criteria include its 2 mV initial offset grade, SOIC-14 package, –40°C to +85°C industrial temperature rating, LinCMOS™ input stage enabling 10¹² Ω input impedance and sub-picoampere bias current, and compatibility with 4–16 V single-supply rails.

Technical Context

The TLC27L4BIDRG4 implements a silicon-gate LinCMOS™ architecture that achieves exceptional DC precision-2 mV V_IO max at 25°C and 3.5 mV over –40°C to +85°C-while maintaining ultra-low quiescent current (68 µA typ. per amplifier at 5 V). Its input stage supports common-mode voltages down to –0.2 V relative to GND and output swing to within 50 mV of GND, enabling true single-supply interfacing with grounded sensors.

It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), latch-up immunity, and stable unity-gain operation (85 kHz GBW, 34° phase margin at 25°C). The device avoids bipolar power penalties while delivering high open-loop gain (50 V/mV min), 87 dB CMRR, and 97 dB supply rejection-critical for noisy industrial environments.

FAQ

What is the maximum input offset voltage specification for TLC27L4BIDRG4 over temperature?

The TLC27L4BIDRG4 has a maximum input offset voltage of 2000 µV at 25°C and 3500 µV over the full –40°C to +85°C operating range, as specified in Section 5.8 of the official TI datasheet (SLOS053E). This 2 mV grade distinguishes it from the standard TLC27L4 (10 mV) and positions it for mid-precision applications where trimming is impractical.

Does TLC27L4BIDRG4 support true single-supply operation with inputs extending below ground?

Yes. The TLC27L4BIDRG4 supports common-mode input voltages down to –0.2 V relative to GND at 5 V supply, enabling direct connection to grounded sensors (e.g., thermocouples, bridge circuits) without level-shifting circuitry. This feature is explicitly confirmed in Section 5.3 (Recommended Operating Conditions) and Table 4-1 (Pin Functions).

What is the quiescent current consumption of TLC27L4BIDRG4 at 5 V supply?

The TLC27L4BIDRG4 draws 39–68 µA per amplifier (156–272 µA total for all four) at 5 V and 25°C, with typical total supply current of 272 µA. At 85°C, IDD drops to 208 µA max (52 µA per amp), as documented in Section 5.8 Electrical Characteristics (I-suffix data). This ultra-low power enables multi-year battery life in remote nodes.

Is TLC27L4BIDRG4 pin-compatible with other TLC27Lx variants in SOIC-14?

Yes. All TLC27Lx quad op-amps-including TLC27L4, TLC27L4A, TLC27L4B, and TLC27L9-in the D (SOIC-14) package share identical pinouts per Figure 4-1 and Table 4-1. The TLC27L4BIDRG4 can replace any other SOIC-14 variant without PCB changes, though performance (e.g., offset, drift) differs by grade.

What packaging and reel quantity does the 'DRG4' suffix indicate for TLC27L4BIDRG4?

The 'DRG4' suffix denotes a SOIC-14 (D) package supplied in tape-and-reel format with 2500 units per reel, per Texas Instruments' standard ordering nomenclature. This packaging is optimized for high-volume automated SMT assembly and is fully compatible with industry-standard pick-and-place equipment.
