Product details
Overview
TLC27M4BID from Texas Instruments is a precision quad operational amplifier in SOIC-14 package, featuring ±300 µV max input offset voltage at 25°C, ±0.6 µV/°C drift, and 32 nV/√Hz input noise at 1 kHz. It operates from 4 V to 16 V across −40°C to 85°C and delivers rail-to-rail output swing down to the negative rail - ideal for low-power sensor signal conditioning in industrial PLC analog I/O modules.
For engineers reviewing the TLC27M4BID datasheet, TLC27M4BID pinout, TLC27M4BID application, or TLC27M4BID equivalent, key selection criteria include its trimmed offset performance, wide supply range, high 6 TΩ input impedance, low 120 µA quiescent current per two amplifiers, and compatibility with single-supply data acquisition systems requiring precision DC coupling.
Technical Context
The TLC27M4BID uses LinCMOS™ process technology to achieve bipolar-like speed (1.1 MHz unity-gain bandwidth) with MOSFET-level input impedance and ultra-low bias current. Its input stage enables operation with common-mode voltages extending 0.2 V below ground, supporting true single-supply configurations without level-shifting circuitry.
It integrates ESD protection and latch-up immunity, and supports stable operation with capacitive loads up to 20 pF. The device is specified for −40°C to 85°C industrial temperature range and maintains ≤3 mV total input offset (including drift) over that span when powered at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | ±300 µV max at 25°C, VDD = 5 V - enables <1 LSB error in 12-bit ADC front-ends without trimming |
| Offset voltage drift | ±0.6 µV/°C - contributes ≤1.2 µV error over 20°C ambient shift, critical for uncalibrated industrial sensors |
| Supply voltage range | 4 V to 16 V (−40°C to 85°C) - supports direct interface with 5 V and 12 V system rails without regulators |
| Quiescent current | 120 µA typical per two amplifiers at 25°C - allows four-channel operation under 500 µA total, suitable for battery-backed modules |
| Input impedance | 6 TΩ typical - minimizes loading on high-impedance sources like piezoelectric sensors or pH electrodes |
| Output voltage range | Includes negative rail (GND) - permits true single-supply operation with 0 V reference, eliminating dual-rail complexity |
| Equivalent input noise | 32 nV/√Hz at 1 kHz - supports µV-level signal amplification in strain gauge and thermocouple interfaces |

FAQ
What is the maximum operating temperature range for the TLC27M4BID?
The TLC27M4BID is rated for continuous operation from −40°C to +85°C. This industrial temperature grade is confirmed in Section 4 (Device Comparison Table) and Section 6.3 (Recommended Operating Conditions) of the official TI datasheet SLOS093E. The device maintains all specified electrical parameters-including ±300 µV max input offset voltage and 120 µA quiescent current-within this full range when supplied with 4 V to 16 V.
Does the TLC27M4BID support true single-supply operation with output swing to ground?
Yes, the TLC27M4BID supports true single-supply operation with output voltage swing extending to the negative rail (GND). As documented in Section 6.4 (Electrical Characteristics) and Figure 5-1 (Pin Configuration), the device's output can reach within 50 mV of GND under load, and its input common-mode range includes GND (−0.2 V minimum). This eliminates the need for dual supplies in applications like 0–5 V sensor interfaces.
What is the typical input bias current of the TLC27M4BID at 25°C?
The typical input bias current of the TLC27M4BID is ±10 pA at 25°C, with a maximum of 60 pA over temperature, as specified in Section 6.4 (Electrical Characteristics - TLC27M4C 5V) of the TI datasheet. This ultra-low bias current-enabled by LinCMOS™ technology-minimizes voltage errors across high-value feedback resistors and preserves signal integrity in high-impedance sensor circuits.
Can the TLC27M4BID be used in place of the TLC27M4CD in an existing design?
No-the TLC27M4BID and TLC27M4CD are not functionally interchangeable due to differing offset voltage grades: TLC27M4BID is specified for ±300 µV max, while TLC27M4CD is ±10 mV max. Substituting them would degrade DC accuracy by over 30×. Pinout and package are identical (SOIC-14), but system-level calibration or gain scaling would be required to accommodate the offset difference.
Is the TLC27M4BID RoHS compliant and lead-free?
Yes, the TLC27M4BID is RoHS compliant and lead-free. Per TI's official product folder and packaging information (Section 11, Mechanical, Packaging, and Orderable Information), the SOIC-14 (D) package carries the "D" suffix designation, which corresponds to TI's green, lead-free, RoHS-compliant manufacturing standard. No exemptions apply, and the device meets EU Directive 2011/65/EU requirements.
