Product details
Overview
TLC274BIDG4 from Texas Instruments is a precision quad operational amplifier optimized for single-supply operation, featuring 2 mV max input offset voltage (25°C), 10.8 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing down to the negative rail. It operates from 4 V to 16 V across –40°C to 85°C and delivers 4.5 MHz unity-gain bandwidth - enabling high-fidelity signal conditioning in low-power sensor front-ends and industrial analog interfaces.
For engineers reviewing the TLC274BIDG4 datasheet, TLC274BIDG4 pinout, TLC274BIDG4 application, or TLC274BIDG4 equivalent, this page provides verified package mapping (SOIC-14), confirmed electrical parameters per TI SLOS092E Rev. JANUARY 2026, real-world design implications of its CMOS input stage, and validated alternative options for precision quad op-amp selection.
Technical Context
The TLC274BIDG4 uses a polysilicon-gate CMOS process to achieve ultra-low input bias current (<60 pA typ. at 25°C) and stable offset voltage drift (0.3 µV/°C). Its input common-mode range extends 0.1 V below GND and up to VDD–1.5 V, supporting true single-supply sensing with grounded references.
Internally, it integrates ESD protection circuitry and latch-up immunity, and its output stage drives ±30 mA while maintaining low-level output voltage ≤50 mV (IOL = 0) - critical for interfacing with low-voltage logic and ADC drivers without level-shifting.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV274IPWR | Lower VIO (2 mV max), lower supply current (1.25 mA/ch), but reduced VDD range (2.7–16 V) and narrower temp range (–40°C to 85°C same) | Better suited for ultra-low-power battery applications; less suitable for 4 V minimum industrial rails | Select TLV274IPWR only if supply voltage can reliably stay ≥2.7 V and total quiescent power budget is <5 mA |
| OPA2333AIDR | Zero-drift architecture, 12 µV max VIO, 0.02 µV/°C drift, but higher cost and 1.8–5.5 V supply limit | Required for sub-0.01% DC accuracy in medical diagnostics or calibration equipment; incompatible with 12 V or 24 V systems | Choose OPA2333AIDR only when microvolt-level offset stability is mandatory and system VDD ≤5.5 V |
Compared with TLV274IPWR and OPA2333AIDR, the TLC274BIDG4 offers the broadest industrial supply range (4–16 V) and proven latch-up immunity - making it the most robust choice for legacy-compatible designs where moderate offset (2 mV) is acceptable and 12 V/24 V rails dominate.

FAQ
What is the maximum input offset voltage specification for TLC274BIDG4 over temperature?
The TLC274BIDG4 has a maximum input offset voltage of 3000 µV across the full operating temperature range of –40°C to +85°C, as specified in Section 4.5 of the TI SLOS092E datasheet. At 25°C, the limit is 2000 µV. This parameter directly impacts DC accuracy in sensor amplification circuits - users should account for this worst-case value in error budgeting for precision measurement systems using the TLC274BIDG4.
Does TLC274BIDG4 support true single-supply operation with inputs referenced to ground?
Yes, the TLC274BIDG4 supports true single-supply operation: its common-mode input voltage range extends to –0.1 V (below GND) at 25°C and –0.1 V to VDD–1.5 V across temperature, and its output swings to within 50 mV of GND. This allows direct interfacing with grounded-sensor configurations - such as thermocouple cold-junction compensation or bridge transducer outputs - without level-shifting circuitry when using the TLC274BIDG4.
What package type and dimensions does TLC274BIDG4 use?
The TLC274BIDG4 is packaged in a 14-pin SOIC (D package) with nominal dimensions of 8.65 mm × 6.00 mm and maximum height of 1.75 mm. It features gull-wing leads, RoHS-compliant matte tin plating, and is rated for surface-mount reflow per JEDEC J-STD-020. This footprint is compatible with standard SOIC-14 PCB layouts and automated assembly processes used for the TLC274BIDG4.
How does the input bias current of TLC274BIDG4 affect high-impedance sensor interfaces?
The TLC274BIDG4 specifies a maximum input bias current of 60 pA at 25°C and 2000 pA at 85°C. When interfacing with high-impedance sources (>1 MΩ), such as pH electrodes or piezoelectric sensors, this bias current introduces voltage error across source impedance - e.g., 2000 pA × 10 MΩ = 20 mV offset. Designers must include guard rings and low-leakage PCB layout practices to maintain accuracy in systems using the TLC274BIDG4.
Can TLC274BIDG4 replace older TLC274CDR or TLC274BIN in existing designs?
Yes - the TLC274BIDG4 is a direct functional and pin-compatible replacement for TLC274CDR (C-suffix, 10 mV VIO) and TLC274BIN (N-package, same specs) in SOIC-14 footprints. It shares identical pinout, electrical characteristics, and thermal ratings. However, due to its tighter 2 mV VIO grade, it improves DC accuracy without requiring layout changes - making the TLC274BIDG4 a drop-in upgrade for legacy systems seeking enhanced precision.
