Product details
Overview
TLC27M4ID from Texas Instruments is a precision quad CMOS operational amplifier optimized for low-power, rail-to-rail output (negative rail inclusive), and high-impedance signal conditioning in industrial and test equipment. It delivers ±300 µV max input offset voltage at 25°C, ±0.6 µV/°C drift, 32 nV/√Hz input noise at 1 kHz, and operates from 4 V to 16 V across –40°C to +85°C.
For engineers reviewing the TLC27M4ID datasheet, TLC27M4ID pinout, TLC27M4ID application, or TLC27M4ID equivalent, this device is selected for precision analog front-ends where low quiescent current (120 µA per two amplifiers), high input impedance (6 TΩ typ), and ESD-protected operation are critical in multiplexed data acquisition and PLC analog I/O modules.
Technical Context
The TLC27M4ID uses LinCMOS™ process technology to achieve bipolar-like speed with MOSFET-level input bias current and power efficiency. Its architecture supports single-supply operation with common-mode input range extending to the negative rail and output swing including the negative rail - enabling true ground-referenced sensing without level-shifting circuitry.
It features internal ESD protection and latch-up immunity, and its electrical characteristics are fully specified over the industrial temperature range (–40°C to +85°C) at supply voltages of 4 V to 16 V. The device maintains stable phase margin (>60° at 25°C) and unity-gain bandwidth of 1.1 MHz under standard load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±300 µV max at 25°C - enables DC-coupled precision gain stages without external trimming in sensor interfaces |
| Offset Drift | ±0.6 µV/°C - ensures <1.5 µV total drift over 0–70°C ambient, critical for long-term calibration stability |
| Supply Current | 120 µA per two amplifiers at 25°C, VDD = 5 V - allows four-channel operation below 500 µA, ideal for battery-backed systems |
| Input Impedance | 6 TΩ typical - minimizes loading on high-Z sources like piezoelectric sensors or pH electrodes |
| Noise Density | 32 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level signals in instrumentation |
| Unity-Gain Bandwidth | 1.1 MHz - sufficient for anti-aliasing filters and moderate-speed signal conditioning up to ~100 kHz closed-loop |
| Common-Mode Range | Extends to negative rail (–0.2 V min) - eliminates need for dual supplies in single-ended sensor interfaces |

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 |
|---|---|---|---|
| TLV2774IDR | Lower offset (250 µV max), higher supply current (530 µA), 2.7–5.5 V supply only | Optimized for 3.3 V systems; unsuitable for 12 V industrial rails or extended temperature range | Select when operating exclusively at 3.3 V with tighter offset budget and higher speed (10 MHz GBW) required |
| OPA4340UA | Rail-to-rail I/O, lower noise (23 nV/√Hz), 2.7–5.5 V supply, no –40°C to +85°C I-grade variant | Requires level-shifting for >5 V supplies; lacks industrial temp grade certification | Prefer for ultra-low-noise 3 V–5 V portable instrumentation where supply headroom is constrained |
Compared with TLV2774IDR and OPA4340UA, the TLC27M4ID uniquely supports 4–16 V operation across –40°C to +85°C while maintaining sub-µV/°C drift and <500 µA total quiescent current - making it the only option for legacy industrial systems requiring wide supply range and certified industrial temperature compliance without sacrificing precision.

FAQ
What is the maximum supply voltage for the TLC27M4ID?
The absolute maximum supply voltage for the TLC27M4ID is 18 V, but the recommended operating range is 4 V to 16 V across the full –40°C to +85°C industrial temperature range. Operation at 16 V is fully characterized for parameters including offset voltage, CMRR, and output swing - making TLC27M4ID suitable for 12 V and 15 V industrial power rails without derating.
Does the TLC27M4ID support rail-to-rail input operation?
No, the TLC27M4ID does not support rail-to-rail input - its common-mode input voltage range extends to the negative rail (–0.2 V minimum) but only to VDD – 1.5 V maximum at 25°C. However, its output swings to within 50 mV of the negative rail and to within 50 mV of VDD, enabling true single-supply operation for output-critical applications like sensor buffering and DAC output driving.
How many amplifiers are integrated in the TLC27M4ID?
The TLC27M4ID integrates four independent precision operational amplifiers in a single SOIC-14 package. Each amplifier has fully specified DC and AC performance - including matched offset, drift, and noise - and operates with complete electrical isolation between channels, as confirmed by CMRR ≥60 dB and no crosstalk specifications exceeding 60 dB in the datasheet.
Is the TLC27M4ID suitable for use in automotive applications?
The TLC27M4ID is not qualified for automotive applications. It is rated for the industrial temperature range (–40°C to +85°C) and carries no AEC-Q100 qualification. For automotive use, TI offers the TLC27M4IPW variant in TSSOP-14 with identical electrical specs but no extended temperature or reliability validation beyond industrial grade - design-in for automotive systems requires explicit qualification testing per OEM requirements.
What is the typical input bias current of the TLC27M4ID at 25°C?
The typical input bias current of the TLC27M4ID is ±10 pA at 25°C, with a maximum of 60 pA over the full industrial temperature range. This ultra-low value - enabled by LinCMOS™ technology - ensures minimal voltage error when interfacing with high-impedance sources such as pH electrodes, piezoelectric sensors, or passive RC filter networks in precision measurement circuits.
