Product details
Overview
TLC27L4BIDR from Texas Instruments is a precision quad operational amplifier in SOIC-14 package, featuring 2 mV max input offset voltage at 25°C, ultra-low 195 µW power consumption at 5 V, and rail-to-rail output swing down to the negative rail. It operates from 4 V to 16 V over –40°C to +85°C and supports single-supply sensor signal conditioning in battery-powered field transmitters.
For engineers reviewing the TLC27L4BIDR datasheet, TLC27L4BIDR pinout, TLC27L4BIDR application, or TLC27L4BIDR equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial sensing use cases, and two technically documented alternative op-amps for design continuity.
Technical Context
The TLC27L4BIDR uses TI's LinCMOS™ process to achieve 10¹² Ω typical input impedance and sub-picoampere input bias current (0.6 pA typ at 25°C), enabling high-impedance sensor interfacing without loading. Its common-mode input range extends 0.2 V below ground, supporting true single-supply operation with inputs referenced to GND.
It delivers 85 kHz unity-gain bandwidth and 0.03 V/µs slew rate at 5 V supply, optimized for low-frequency precision amplification-not high-speed signal processing. Phase margin remains stable at 34° (typ) across temperature, ensuring robust stability with capacitive loads up to 20 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 2 mV max at 25°C - enables accurate DC-coupled amplification of µV-level sensor outputs without trimming |
| Supply Current (4 amps) | 68 µA max at 25°C - supports multi-year battery life in remote 4–20 mA loop-powered transmitters |
| Input Impedance | 10¹² Ω typical - prevents loading of high-Z sources like piezoresistive pressure bridges or thermopiles |
| Common-Mode Input Range | –0.2 V to 3.5 V at 5 V supply - accepts signals referenced to ground in single-supply systems |
| Output Voltage Swing | Within 50 mV of GND and 0.9 V of VDD - delivers full dynamic range for ADC input buffering |
| ESD Rating | 2000 V HBM - withstands handling in non-ESD-controlled industrial assembly environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L4CDR | 10 mV max VIO, rated for 0°C to 70°C only - higher offset, narrower temp range | Suitable for cost-sensitive commercial-grade systems where calibration is performed at room temperature | Select when budget constraints outweigh long-term drift and extended temperature requirements |
| TLC27L4BIPW | Identical electrical specs, but TSSOP-14 (PW) package - 5.0 mm × 4.4 mm, finer pitch | Better suited for space-constrained PCBs in handheld or modular sensor nodes | Choose for compact layouts requiring smaller footprint; verify thermal derating (700 mW vs SOIC's 950 mW) |

FAQ
What is the maximum input offset voltage specification for TLC27L4BIDR at 25°C?
The TLC27L4BIDR has a maximum input offset voltage of 2 mV at 25°C, as specified in the Electrical Characteristics table for I-suffix devices under VDD = 5 V conditions. This value is guaranteed across the full –40°C to +85°C operating range, with a worst-case of 3.5 mV at temperature extremes.
Does TLC27L4BIDR support true single-supply operation with inputs referenced to ground?
Yes, the TLC27L4BIDR supports true single-supply operation: its common-mode input voltage range extends to –0.2 V (below GND) at 5 V supply, and its output swings within 50 mV of GND. This allows direct interfacing with ground-referenced sensors without level-shifting circuitry.
What package type and dimensions does TLC27L4BIDR use?
The TLC27L4BIDR is supplied in the SOIC-14 (D) package: 8.65 mm × 3.91 mm body size, 1.75 mm height, 1.27 mm lead pitch. It is RoHS-compliant, halogen-free, and qualified for surface-mount reflow per JEDEC J-STD-020.
How does the input bias current of TLC27L4BIDR compare to bipolar op-amps?
The TLC27L4BIDR exhibits typical input bias current of 0.6 pA at 25°C-over six orders of magnitude lower than typical bipolar op-amps (e.g., LM324: ~45 nA). This ultra-low bias current prevents signal degradation when amplifying from high-impedance sources like pH electrodes or photodiodes.
Is TLC27L4BIDR pin-compatible with other TLC27Lx variants in SOIC-14?
Yes, all TLC27Lx devices in the D (SOIC-14) package-including TLC27L4, TLC27L4A, TLC27L4B, and TLC27L9-are fully pin-compatible. The only differences are electrical grade (VIO), temperature rating (C/I suffix), and minor parametric shifts; no PCB redesign is needed when upgrading within the same package.
