Product details
Overview
TLC27M4CNS from Texas Instruments is a LinCMOS™ precision quad operational amplifier optimized for low-power, high-input-impedance analog signal conditioning in single-supply systems. It delivers ±300 µV max input offset voltage at 25°C (VDD = 5 V), ±0.6 µV/°C drift, 32 nV/√Hz input noise at 1 kHz, rail-to-rail output swing to negative rail, and 120 µA typical quiescent current - enabling high-accuracy sensor interfacing and multiplexed data acquisition.
For engineers reviewing the TLC27M4CNS datasheet, TLC27M4CNS pinout, TLC27M4CNS application, or TLC27M4CNS equivalent, this device is selected for precision instrumentation requiring stable DC performance across 0°C to 70°C, wide 3–16 V supply range, and ESD-protected operation in space-constrained SOP-14 layouts.
Technical Context
The TLC27M4CNS uses LinCMOS™ process technology to combine CMOS input-stage advantages - 6 TΩ typical input impedance, pA-level bias currents, and inherent latch-up immunity - with trimmed bipolar-like precision. Its architecture supports single-supply operation with common-mode input range extending to −0.2 V (below ground) and output swing to the negative rail.
It features internal ESD protection circuitry and is characterized across multiple supply voltages (5 V and 10 V) and temperature grades (C-suffix: 0°C to 70°C). Electrical specifications are validated per TI's SLOS093E production data sheet, including guaranteed parameters for offset voltage, drift, noise, and open-loop gain under defined load and test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±300 µV max at 25°C, VDD = 5 V - enables sub-mV DC error in precision sensor front-ends without external trimming. |
| Offset Voltage Drift | ±0.6 µV/°C (25°C to 70°C) - ensures <2 µV total drift over full commercial temperature range, critical for stable long-term measurements. |
| Input Noise Density | 32 nV/√Hz at f = 1 kHz - supports low-noise amplification of microvolt-level signals from strain gauges or thermocouples. |
| Supply Current (4 amps) | 420–1120 µA at 25°C, VDD = 5 V - allows battery-powered or energy-sensitive designs with four independent precision channels. |
| Common-Mode Input Range | −0.2 V to 3.5 V (full range) at VDD = 5 V - permits direct sensing of signals referenced below ground in single-supply systems. |
| Output Voltage Swing | Includes negative rail (VOL ≤ 50 mV at IOL = 0) - simplifies interface to ADCs or logic with ground-referenced inputs. |
| Unity-Gain Bandwidth | 525 kHz typical at VDD = 5 V - sufficient for anti-aliasing, active filtering, and moderate-speed signal conditioning up to ~100 kHz. |
Pinout & Package
The TLC27M4CNS is supplied in an NS (SOP-14) package measuring 10.3 mm × 5.3 mm, with gull-wing leads suitable for surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier A output - drives external load or next stage; rail-to-rail capable. |
| 1IN−, 1IN+ | Inverting / Non-inverting Input | Differential inputs for channel A - high-impedance (6 TΩ) nodes sensitive to PCB leakage and layout parasitics. |
| VDD | Positive Supply | Primary power rail (3–16 V); decoupling capacitor required near pin for stability. |
| 2IN+, 2IN−, 2OUT | Input / Output | Amplifier B channel - electrically identical to channel A; supports independent gain stages. |
| 3IN+, 3IN−, 3OUT | Input / Output | Amplifier C channel - fully isolated; enables multi-channel signal conditioning on one die. |
| GND | Ground / Negative Rail | Reference node for all inputs and outputs; must be low-impedance return path. |
| 4IN+, 4IN−, 4OUT | Input / Output | Amplifier D channel - completes quad configuration; supports simultaneous 4-channel buffering or filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Trimmed offset voltage | ±300 µV max at 25°C ensures minimal initial calibration burden in production test. |
| Low input bias current | ±10 pA typical at 25°C enables high-Z source interfacing (e.g., pH electrodes, photodiodes) without significant error. |
| Rail-to-rail output swing | Output reaches within 50 mV of GND - maximizes dynamic range when using single-ended ADCs referenced to ground. |
| ESD protection circuitry | Integrated protection meets JEDEC JS-001 Class 2 (2 kV HBM) - reduces need for external TVS in board-level ESD design. |
| Latch-up immunity | Designed-in immunity per JEDEC JESD78 - prevents catastrophic failure during overvoltage transients or supply sequencing faults. |
Applications
| Multiplexed Data Acquisition | Test & Measurement Equipment |

| Programmable Logic Controllers | Analog I/O Modules |
|
Use Scenario: Isolated analog input conditioning in industrial PLC backplanes handling 4–20 mA loop signals and voltage sensors. IC Role / Device Role: Signal translator and filter stage - converts current loops to voltage, rejects common-mode noise, and drives isolation barriers. Use Value: Common-mode input range to −0.2 V accommodates grounded-loop configurations; ESD protection enhances field reliability. |
Use Scenario: Multi-channel analog input/output modules for factory automation, where space and thermal budget constrain component count. IC Role / Device Role: Quad op-amp providing independent gain, filtering, and level-shifting for 4 sensor channels in one SOP-14 footprint.

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 |
|---|---|---|---|
| TLC27M4CD | Same electrical specs but in SOIC-14 (D) package (8.65 mm × 3.9 mm); no NS variant offered. | Requires PCB redesign for smaller SOP-14 footprint; otherwise drop-in functional replacement. | Select when SOIC-14 is preferred for legacy layout compatibility or automated assembly tooling. |
| TLC27L4CNS | Lower supply current (120 µA typ for 4 amps), but higher max offset (10 mV) and reduced bandwidth (110 kHz). | Suitable only for ultra-low-power, non-critical DC applications - not interchangeable where <1 mV offset is required. | Choose only if power budget is tighter than precision requirements; verify offset and drift meet system error budget. |
Compared with TLC27M4CD and TLC27L4CNS, the TLC27M4CNS uniquely balances SOP-14 compactness, ±300 µV offset, and 525 kHz bandwidth - making it optimal for space-constrained, precision analog modules where both size and DC accuracy are critical.

FAQ
What is the maximum operating supply voltage for the TLC27M4CNS?
The absolute maximum supply voltage (VDD) for the TLC27M4CNS is 18 V, but the recommended operating range is 3 V to 16 V across 0°C to 70°C. Operation at 16 V is supported per TI's SLOS093E datasheet Section 6.3, with validated performance for offset, noise, and bandwidth - exceeding typical 5 V or 12 V system rails.
Does the TLC27M4CNS support true rail-to-rail input operation?
No - the TLC27M4CNS does not support rail-to-rail input. Its common-mode input voltage range extends to −0.2 V (below ground) and up to 3.5 V at VDD = 5 V, meaning it accepts inputs slightly below GND but not up to VDD. However, its output swings to the negative rail (GND), which is explicitly confirmed in Section 6.4 of the datasheet.
How many amplifiers are integrated in the TLC27M4CNS and how are they configured?
The TLC27M4CNS integrates four independent, identical operational amplifiers in a single NS (SOP-14) package. Pin functions are defined in Table 5-1: channels A–D occupy pins 1–3 (A), 5–7 (B), 8–10 (C), and 12–14 (D), with shared VDD (pin 4) and GND (pin 11) - enabling fully isolated signal paths without crosstalk.
What is the typical input bias current specification for the TLC27M4CNS at 25°C?
The typical input bias current for the TLC27M4CNS is ±10 pA at 25°C, with a maximum of 60 pA over temperature (0°C to 70°C), as specified in Section 6.4 of the SLOS093E datasheet. This ultra-low value stems from its LinCMOS™ input stage and enables accurate amplification of high-impedance sources like piezoelectric sensors or pH probes.
Is the TLC27M4CNS pin-compatible with other devices in the TLC27Mxx family?
Yes - the TLC27M4CNS shares identical pinout and footprint with all TLC27Mxx quad variants in NS (SOP-14), including TLC27M4ACNS and TLC27M4BCNS. Differences are limited to internal trimming (affecting offset voltage grade) and temperature range suffixes; no PCB layout change is needed when substituting within the same package type.
