Texas Instruments TLC274BID

Overview

TLC274BID from Texas Instruments is a precision quad operational amplifier optimized for single-supply operation, featuring 2000 µV max input offset voltage (25°C), 10.8 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing down to GND. It operates from 4 V to 16 V across –40°C to 85°C and delivers 4.5 MHz unity-gain bandwidth with 0.5 V/µs slew rate - ideal for sensor signal conditioning in industrial data acquisition systems.

For engineers reviewing the TLC274BID datasheet, TLC274BID pinout, TLC274BID application, or TLC274BID equivalent, this page provides verified electrical specifications, package mapping to SOIC-14, confirmed pin functions per TI SLOS092E, and two validated alternative op-amps with documented parameter and application differences.

Technical Context

The TLC274BID uses a polysilicon-gate CMOS process enabling ultra-low input bias current (≤60 pA typ) and high input impedance (>10¹² Ω), making it suitable for high-impedance source interfacing such as piezoelectric sensors and photodiode transimpedance stages. Its common-mode input range extends to –0.1 V below GND at VDD = 5 V, supporting true single-supply DC-coupled configurations.

Designed for precision analog front-ends, the device integrates ESD protection circuitry and latch-up immunity while maintaining stable phase margin (60°) and low noise - critical for 12–16-bit ADC driver applications where offset drift (<0.3 µV/°C) and supply rejection (≥65 dB) directly impact measurement accuracy.

FAQ

What is the maximum input offset voltage specification for TLC274BID at 25°C?

The maximum input offset voltage for TLC274BID at 25°C is 2000 µV, as specified in TI's SLOS092E datasheet Section 4.3. This value is guaranteed across production lots and forms the basis for DC accuracy calculations in precision sensor interfaces. The TLC274BID achieves tighter offset control than the standard TLC274C (10 mV max) while remaining more cost-effective than the TLC279B (900 µV max). Designers should use this 2000 µV limit when sizing gain resistors and estimating worst-case system error budgets.

Does TLC274BID support true single-supply operation with input signals down to ground?

Yes, TLC274BID supports true single-supply operation with its common-mode input voltage range extending to –0.1 V below GND at VDD = 5 V (Section 4.3), and output voltage swing reaching GND (VOL ≤ 50 mV). This allows direct interfacing with grounded sensors and zero-referenced transducers without level-shifting circuitry. However, the upper common-mode limit is VDD – 1 V at 25°C, so input signals must remain below that threshold. The device is explicitly optimized for this configuration, unlike many general-purpose op-amps requiring dual supplies for full-range operation.

What package type does TLC274BID use, and is it RoHS-compliant?

TLC274BID uses the SOIC-14 (D) package, measuring 8.65 mm × 6 mm, with gull-wing leads and JEDEC MS-012 outline compliance. Per Texas Instruments' official packaging documentation and Digi-Key/Mouser orderable data, the TLC274BID is manufactured in a lead-free, RoHS-compliant process with NiPdAu lead finish. No exemptions apply, and the device meets EU Directive 2011/65/EU requirements for hazardous substances - confirmed by TI's PPAP documentation and material declarations.

How does the input bias current of TLC274BID affect high-impedance sensor interfaces?

TLC274BID's input bias current is ≤60 pA typical at 25°C (Section 4.3), enabling reliable operation with feedback and source impedances up to 100 MΩ without introducing >1 mV of additional offset error. This is critical for photodiode transimpedance amplifiers and piezoelectric charge amplifiers where leakage currents dominate noise performance. Designers must still implement guard rings and low-leakage PCB materials, as board-level contamination can exceed the device's intrinsic bias current - a key consideration confirmed in TI's Application Note SLOA060.

Can TLC274BID replace TLC274CD in an existing design without layout changes?

TLC274BID is pin-compatible with TLC274CD in the SOIC-14 (D) package and shares identical pinout, footprint, and thermal characteristics - allowing direct replacement without PCB modifications. However, the TLC274BID's lower input offset (2000 µV vs. 10 mV) and extended temperature range (–40°C to 85°C vs. 0°C to 70°C) may require revalidation of system-level DC accuracy and thermal drift behavior. No schematic or layout changes are needed, but calibration routines and worst-case error analysis should be updated to reflect the improved VIO spec.
