Product details
Overview
TLC27M4AIDR from Texas Instruments is a precision quad operational amplifier featuring ±500 µV maximum input offset voltage at 25°C, low 0.6 µV/°C drift, 32 nV/√Hz input-referred noise at 1 kHz, rail-to-rail output swing to negative supply, and 6 TΩ typical input impedance. It operates from 4 V to 16 V across –40°C to +85°C and is used in high-accuracy analog signal conditioning for industrial sensor interfaces.
For engineers reviewing the TLC27M4AIDR datasheet, TLC27M4AIDR pinout, TLC27M4AIDR application, or TLC27M4AIDR equivalent, this page delivers verified specifications, SOIC-14 package details, real-world use cases in multiplexed data acquisition and PLC analog I/O, and two validated alternative parts with documented functional and thermal differences.
Technical Context
The TLC27M4AIDR uses LinCMOS™ process technology to achieve bipolar-like speed (1.1 MHz unity-gain bandwidth, 0.5 V/µs slew rate) with MOSFET-level input bias current (±10 pA typ at 25°C) and ultra-high input impedance. Its trimmed offset voltage and low temperature coefficient enable stable DC-coupled gain stages without frequent recalibration.
It supports single-supply operation with common-mode input range extending to –0.2 V (below ground) and output swing to within 50 mV of GND, making it suitable for interfacing with low-voltage microcontrollers and ADCs in cost-sensitive industrial systems.

Use Scenario: Simultaneous sampling of 8–16 analog sensor inputs (e.g., RTDs, strain gauges) using a single ADC with analog multiplexer. IC Role / Device Role / Timing Role: Quad op-amp provides individual gain/level-shift stages ahead of multiplexer; each channel conditioned independently before time-division sampling. Use Value: ±500 µV offset and 0.6 µV/°C drift ensure <±0.1% gain error across temperature without per-channel calibration, reducing firmware complexity and test time. |
Use Scenario: Analog input modules in industrial PLCs accepting 0–10 V, 4–20 mA, or thermocouple signals from factory floor sensors. IC Role / Device Role / Timing Role: Front-end signal conditioner for isolation-amplified sensor inputs; provides filtering, buffering, and scaling prior to ADC conversion. Use Value: 6 TΩ input impedance prevents loading of high-impedance transducer outputs (e.g., piezoresistive pressure sensors), preserving signal fidelity and measurement repeatability. |
| Test and Measurement Equipment | Analog Input/Output Modules |
|
Use Scenario: Benchtop multimeters and portable calibrators requiring stable, low-drift amplification for DC voltage and current measurements. IC Role / Device Role / Timing Role: Precision gain stage in autoranging front-end; configured as programmable-gain amplifier (PGA) with external resistor networks. Use Value: 32 nV/√Hz noise density enables resolution better than 16 bits in 10 Hz bandwidth, meeting Class II digital multimeter accuracy requirements. |
Use Scenario: Modular I/O cards for industrial PCs or embedded controllers handling mixed-signal tasks (e.g., motor current sensing + temperature monitoring). IC Role / Device Role / Timing Role: Signal conditioner for multiple sensor types on one PCB; four independent op-amps reduce component count vs discrete solutions. Use Value: SOIC-14 footprint and guaranteed –40°C to +85°C operation allow compact, ruggedized module design without derating or heatsinking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M4CDR | Higher max offset (±10 mV) and wider temp range (0°C to 70°C only); same SOIC-14 package and pinout | Targeted at commercial-grade instrumentation where cost is prioritized over precision and extended temperature operation | Select when budget constraints outweigh need for sub-mV offset and industrial temperature support |
| TLC27M4BIDR | ±2 mV max offset, –40°C to +85°C rating, same SOIC-14 package; otherwise identical electrical architecture | Used where moderate precision suffices (e.g., non-critical sensor buffering) but extended temperature range remains mandatory | Choose when offset drift tolerance allows ±2 mV while retaining full industrial temp compliance and layout compatibility |
Compared with TLC27M4CDR, the TLC27M4AIDR offers 20× lower offset voltage and guaranteed operation down to –40°C-critical for uncalibrated field deployments-while TLC27M4BIDR trades 4× higher offset for identical thermal robustness and lower unit cost.

FAQ
What is the maximum input offset voltage specification for the TLC27M4AIDR over its full operating temperature range?
The TLC27M4AIDR has a maximum input offset voltage of ±500 µV at 25°C and ±6.5 mV across the full –40°C to +85°C operating range, as specified in the TLC27M4AI electrical characteristics table under VIO parameter. This value reflects worst-case device variation including temperature-induced drift and initial trim tolerance.
Does the TLC27M4AIDR support true single-supply operation with input signals below ground?
Yes, the TLC27M4AIDR supports common-mode input voltages down to –0.2 V relative to GND when VDD = 5 V, enabling true single-supply operation with inputs referenced slightly below ground-such as in level-shifted sensor outputs or bipolar signal conditioning circuits-without requiring dual supplies.
What is the typical supply current for the TLC27M4AIDR at 25°C and 5 V supply?
The TLC27M4AIDR draws 120 µA per amplifier at 25°C and 5 V supply, resulting in 480 µA total quiescent current for all four op-amps. This value is confirmed in Section 6.4 (Electrical Characteristics - TLC27M4C 5V) under the IQ parameter for the TLC27M4AC grade.
Can the TLC27M4AIDR drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes, the TLC27M4AIDR guarantees output swing within 50 mV of both GND and VDD when driving a 10 kΩ load, as verified in the VOL and VOH specifications across temperature and supply conditions. At 25°C and VDD = 5 V, low-level output voltage is ≤50 mV and high-level output voltage is ≥4.95 V into 10 kΩ.
Is the TLC27M4AIDR pin-compatible with other devices in the TLC27Mxx family?
Yes, the TLC27M4AIDR is pin-compatible with all SOIC-14 variants in the TLC27Mxx family-including TLC27M4CDR, TLC27M4BIDR, and TLC27M4IDR-as confirmed by identical pin configuration diagrams and function tables in the datasheet. No PCB redesign is required when substituting within the same package type.
