Product details
Overview
TLC27L9ID from Texas Instruments is a precision quad operational amplifier using LinCMOS™ technology, designed for ultra-low-power, single-supply sensor signal conditioning. It delivers 1 mV max input offset voltage (25°C), 10¹² Ω input impedance, and 195 µW typical power consumption at 5 V - enabling battery-powered field transmitters and smoke detectors requiring rail-to-rail output swing and extended common-mode range down to the negative rail.
For engineers reviewing the TLC27L9ID datasheet, TLC27L9ID pinout, TLC27L9ID application, or TLC27L9ID equivalent, this page provides verified specifications, SOIC-14 package details, real-world use cases in industrial sensing, and validated alternative options for precision analog front-end design.
Technical Context
The TLC27L9ID implements a silicon-gate LinCMOS™ architecture that achieves exceptional DC precision (1 mV VIO max) and long-term stability (0.1 µV/month drift), while avoiding bipolar power penalties. Its input stage supports common-mode voltage down to −0.2 V (at VDD = 5 V), and its output swings to within 1 mV of GND and up to 4.1 V under load.
It operates across −40°C to +85°C (I-suffix grade), with supply voltage range 4 V to 16 V, IDD ≤ 68 µA (typical, 25°C), and unity-gain bandwidth of 85 kHz (VDD = 5 V). Input bias current remains below 0.6 pA (25°C), enabling high-impedance source interfacing without significant error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIO max | 1000 µV at 25°C - enables high-accuracy DC amplification without trimming in pressure/temperature transmitter front ends |
| Supply voltage | 4 V to 16 V - supports wide-input industrial power rails and battery-backed operation down to 4 V |
| IIB (typ) | 0.6 pA at 25°C - preserves signal integrity when amplifying from high-Z sensors (e.g., piezoresistive bridges) |
| Input impedance | 10¹² Ω - minimizes loading on passive sensor elements and RC filter networks |
| Power consumption | 195 µW at 5 V (25°C) - extends battery life in remote, low-duty-cycle field transmitters |
| Common-mode range | −0.2 V to 3.5 V (VDD = 5 V) - allows direct interface to ground-referenced sensors without level-shifting |
| Output swing | Within 1 mV of GND and up to 4.1 V (VDD = 5 V, RL = 1 MΩ) - maximizes dynamic range in single-supply ADC driver stages |
Pinout & Package
Package: SOIC-14 (D package), 8.65 mm × 3.91 mm, surface-mount, tape-and-reel compatible.

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 |
|---|---|---|---|
| TLV27L4IDR | Lower VIO (500 µV max), same SOIC-14 package, but only rated for 0°C to 70°C (C-suffix) | Best suited for cost-sensitive commercial-grade sensor modules where extended temperature range is not required | Select when tighter initial offset is prioritized over −40°C operation and long-term drift stability |
| OPA2333AIDR | Zero-drift architecture, 2 µV max VIO, 0.02 µV/°C drift, but higher supply current (17 µA per amp) | Preferred for high-precision, low-drift applications like medical instrumentation where offset drift dominates error budget | Choose when ultra-low drift outweighs ultra-low power; verify layout compatibility due to different pinout |
Compared with TLV27L4IDR, TLC27L9ID offers superior temperature range (−40°C to +85°C) and proven long-term offset stability (0.1 µV/month), while OPA2333AIDR delivers lower drift but consumes ~25× more quiescent current - making TLC27L9ID optimal for battery-constrained industrial transmitters requiring guaranteed performance across harsh environments.

FAQ
What is the maximum input offset voltage specification for TLC27L9ID at 25°C?
The TLC27L9ID has a maximum input offset voltage of 1000 µV (1 mV) at 25°C, as specified in the Electrical Characteristics table for the I-suffix grade under VDD = 5 V conditions. This value is confirmed across the −40°C to +85°C operating range, with a worst-case of 2000 µV at temperature extremes.
Does TLC27L9ID support true rail-to-rail output swing?
The TLC27L9ID does not provide full rail-to-rail output swing. Its low-level output reaches within 1 mV of GND, but its high-level output is limited to approximately 4.1 V at VDD = 5 V (i.e., ~0.9 V below VDD). This behavior is documented in the VOL and VOH specifications and applies across the full operating temperature range.
What package type is used for the TLC27L9ID part number?
The TLC27L9ID uses the SOIC-14 (D) package: 14-pin small-outline integrated circuit, 8.65 mm × 3.91 mm body size, with standard 1.27 mm lead pitch. This is explicitly listed in the Device Information table and confirmed in Section 10 (Mechanical, Packaging, and Orderable Information) of the datasheet.
Can TLC27L9ID operate from a single 3.3 V supply?
No. The TLC27L9ID requires a minimum supply voltage of 4 V for operation across its full −40°C to +85°C temperature range (I-suffix rating). While some C-suffix variants support 3 V, the 'I' suffix mandates 4 V minimum - attempting 3.3 V risks undefined behavior, reduced gain, or failure to meet VIO and CMRR specifications.
Is ESD protection built into the TLC27L9ID?
Yes. The TLC27L9ID incorporates internal ESD-protection circuitry qualified to 2000 V per MIL-STD-883C, Method 3015.2. This protection guards against functional failures during handling and board assembly but does not eliminate the need for standard ESD precautions during PCB manufacturing and test.
