Product details
Overview
TLC27L4ID from Texas Instruments is a precision quad operational amplifier using LinCMOS™ technology, designed for low-power, single-supply sensor signal conditioning. It delivers 10 mV max input offset voltage (25°C), ultra-low 195 µW quiescent power at 5 V, and rail-to-rail output swing with common-mode input extending below ground. It is used in battery-powered field transmitters including pressure, temperature, and level sensing systems.
For engineers reviewing the TLC27L4ID datasheet, TLC27L4ID pinout, TLC27L4ID application, or TLC27L4ID equivalent, key selection considerations include its I-suffix industrial temperature range (–40°C to +85°C), SOIC-14 package, 10¹² Ω input impedance, and compatibility with low-voltage remote analog front-ends requiring stable DC precision and ESD-hardened operation.
Technical Context
The TLC27L4ID implements a silicon-gate LinCMOS™ input stage enabling high input impedance (>10¹² Ω), femtoamp-level bias currents (0.6 pA typ), and latch-up immunity-without bipolar power penalties. Its architecture supports true single-supply operation with common-mode input range extending 0.2 V below GND and output swing to within 50 mV of GND at 5 V supply.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2) and exhibits low drift (0.1 µV/month typical offset voltage drift), making it suitable for long-term deployed instrumentation where parametric stability is critical across temperature and time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 10 mV at 25°C - sets worst-case DC error floor in precision gain stages and sensor bridges |
| Supply Current (typ) | 68 µA per amplifier (272 µA total) at 5 V - enables multi-year battery life in wireless sensor nodes |
| Input Impedance | 10¹² Ω typical - minimizes loading on high-Z sources like piezoresistive sensors and pH electrodes |
| Common-Mode Input Range | –0.2 V to 3.5 V at 5 V supply - allows direct interfacing to grounded-referenced transducers without level-shifting |
| Output Voltage Swing | Within 50 mV of GND and 0.9 V of VDD at 5 V - supports full dynamic range utilization in 3.3 V/5 V microcontroller ADC interfaces |
| Unity-Gain Bandwidth | 85 kHz at 5 V, 25°C - sufficient for DC-coupled sensor amplification and anti-aliasing filtering up to ~10 kHz |
| ESD Rating | 2000 V HBM - provides robust handling margin during PCB assembly and field maintenance |

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 |
|---|---|---|---|
| TLV2464IDR | Lower VIO (1.6 mV max), higher supply current (550 µA total), rail-to-rail I/O, 2.5 V min supply | Better DC precision but 2.8× higher power - suited for AC-coupled or higher-speed applications where battery life is secondary | Select TLV2464IDR when tighter offset and bandwidth (6 MHz) are needed, and power budget allows >500 µA total quiescent current |
| OPA4340UA | Lower noise (23 nV/√Hz), higher slew rate (0.6 V/µs), 1.8 V min supply, no ESD rating specified | Superior AC performance and lower noise - ideal for audio or fast-response sensor interfaces, but lacks documented ESD hardening | Select OPA4340UA for low-noise, wideband applications where ESD robustness is managed externally and supply can be as low as 1.8 V |
Compared with TLV2464IDR and OPA4340UA, the TLC27L4ID trades bandwidth and noise for ultra-low power and proven ESD resilience - making it uniquely suited for cost-sensitive, long-life, industrial-grade sensor transmitters operating from 4–16 V supplies.

FAQ
What is the maximum operating temperature range for the TLC27L4ID?
The TLC27L4ID is characterized for operation from –40°C to +85°C (I-suffix grade). This industrial temperature range is validated per TI's SLOS053E datasheet, with electrical specifications guaranteed across the full span - including input offset voltage, supply current, and common-mode input range. The device maintains functionality beyond these limits, but parametric performance is not assured outside the specified range.
Does the TLC27L4ID support true rail-to-rail output operation?
Yes, the TLC27L4ID provides rail-to-rail output swing: at 5 V supply, its low-level output reaches within 50 mV of GND and high-level output approaches within 0.9 V of VDD. While not symmetrical near both rails, this capability enables full utilization of 3.3 V or 5 V ADC input ranges without external level-shifting circuitry - a key advantage in single-supply sensor signal chains.
Can the TLC27L4ID operate from a 3.3 V supply?
No - the TLC27L4ID requires a minimum supply voltage of 4 V under industrial temperature conditions (–40°C to +85°C). At 3.3 V, the device may not meet guaranteed specifications for output swing, gain, or input common-mode range. For 3.3 V systems, consider alternatives such as the TLV2464 or OPA4340, which specify operation down to 2.5 V or 1.8 V respectively.
How does the input offset voltage drift specification apply to the TLC27L4ID?
The TLC27L4ID exhibits typically 0.1 µV/month input offset voltage drift, including the first 30 days - a metric verified per TI's characterization methodology. This low drift rate directly supports long-term calibration stability in field-deployed equipment, reducing maintenance frequency and enabling predictive calibration scheduling in safety-critical monitoring systems.
Is the TLC27L4ID pin-compatible with other devices in the TLC27Lx family?
Yes - the TLC27L4ID shares identical SOIC-14 (D package) pinout and footprint with TLC27L4AID, TLC27L4BID, and TLC27L9ID. All variants use the same 14-pin configuration, terminal functions, and recommended layout practices. This allows direct substitution within the same family for offset voltage grade upgrades without PCB redesign - provided thermal and supply constraints remain compatible.
