Product details
Overview
TLC27L9IDG4 from Texas Instruments is a precision quad operational amplifier in SOIC-14 package, featuring 1 mV max input offset voltage at 25°C, ultra-low 195 µW power consumption at 5 V, and rail-to-rail output swing down to the negative rail. It operates from 4 V to 16 V over –40°C to +85°C and supports single-supply sensor signal conditioning in battery-powered field transmitters.
For engineers reviewing the TLC27L9IDG4 datasheet, TLC27L9IDG4 pinout, TLC27L9IDG4 application, or TLC27L9IDG4 equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial temperature-grade performance, and real-world design context for low-power precision analog front-ends.
Technical Context
The TLC27L9IDG4 uses TI's LinCMOS™ silicon-gate process to achieve 10¹² Ω typical input impedance, sub-picoampere bias currents (0.6 pA typ at 25°C), and latch-up immunity-enabling high-impedance sensor interfacing without loading effects. Its input common-mode range extends 0.2 V below GND, supporting true single-supply operation with ground-referenced inputs.
Designed for stability in unity-gain configurations, it delivers 85 kHz unity-gain bandwidth and 34° phase margin at 25°C with 20 pF capacitive load, while maintaining CMRR ≥65 dB and PSRR ≥70 dB across its full operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 1000 µV at 25°C - enables <1 LSB error in 10-bit ADC interfaces with gain ≤10 |
| Supply Current (typ) | 68 µA per amplifier at 5 V - supports >10-year battery life in 3.6 V coin-cell–powered sensors |
| Input Impedance (typ) | 10¹² Ω - prevents signal attenuation when buffering high-Z sources like piezoelectric or pH electrodes |
| Common-Mode Input Range | Extends to –0.2 V below GND - allows direct connection of 0–VREF transducer outputs without level-shifting |
| Output Voltage Swing | Down to GND (1 mV typ low-level output) - preserves dynamic range in single-supply 0–5 V systems |
| Unity-Gain Bandwidth | 85 kHz at 25°C - sufficient for DC–10 kHz sensor signal amplification with <0.1% gain error |
| ESD Rating | 2000 V HBM - meets IEC 61000-4-2 Level 2 for industrial field equipment handling |
Pinout & Package
Package: SOIC-14 (D package), 8.65 mm × 3.91 mm, surface-mount, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+ | Noninverting input, Channel 1 | High-impedance node for reference or sensor signal routing; immune to PCB leakage due to 10¹² Ω ZIN |
| 1IN– | Inverting input, Channel 1 | Feedback node for stable closed-loop gain configuration; accepts resistor networks up to 10 MΩ |
| 1OUT | Output, Channel 1 | Capable of sourcing/sinking ±30 mA; drives 1 MΩ loads to within 1 mV of GND or 0.9 V of VDD |

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 |
|---|---|---|---|
| TLV27L4IDR | Lower VIO (500 µV max), but only rated for 0°C to 70°C; 100 µA supply current | Not suitable for extended industrial temperature environments (–40°C to +85°C) | Select TLC27L9IDG4 when guaranteed performance across full industrial temp range is required |
| OPA2333AIDR | Zero-drift architecture; 10 µV VIO max, but 55 µA per amp and 360 µW power at 5 V | Better DC accuracy but higher power; requires external reference for single-supply rail-to-rail output | Choose TLC27L9IDG4 for cost-sensitive, ultra-low-power, self-contained single-supply designs where 1 mV VIO is sufficient |
Compared with TLV27L4IDR, TLC27L9IDG4 provides wider temperature qualification and lower power; versus OPA2333AIDR, it trades zero-drift precision for 3× lower quiescent power and integrated rail-to-rail output capability without external components.

FAQ
What is the maximum input offset voltage specification for TLC27L9IDG4 at 25°C?
The TLC27L9IDG4 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 guaranteed across the full –40°C to +85°C operating range up to 2000 µV, making it suitable for precision DC-coupled applications where initial calibration tolerance is critical.
Does TLC27L9IDG4 support true single-supply operation with inputs referenced to ground?
Yes, the TLC27L9IDG4 supports true single-supply operation: its common-mode input voltage range extends to –0.2 V below GND at 25°C (and –0.2 V to 3.5 V over –40°C to +85°C with VDD = 5 V), allowing ground-referenced sensor signals to be applied directly to IN+ or IN– without level-shifting circuitry - a key enabler for simplified 3.3 V or 5 V sensor front-ends.
What package type and footprint does TLC27L9IDG4 use?
TLC27L9IDG4 uses the SOIC-14 (D) package: 14-pin, narrow-body surface-mount outline measuring 8.65 mm × 3.91 mm with 1.27 mm lead pitch. It is JEDEC MS-012AC compliant and compatible with standard reflow soldering profiles, enabling automated assembly in high-volume industrial PCB manufacturing.
How does the power consumption of TLC27L9IDG4 compare to other precision quad op-amps?
TLC27L9IDG4 consumes only 68 µA per amplifier (272 µA total) at 5 V and 25°C, translating to just 195 µW total quiescent power - significantly lower than most precision quads (e.g., OPA2333 draws 55 µA per amp but lacks rail-to-rail output). This ultra-low power enables multi-year operation from primary batteries in remote field devices without compromising DC accuracy.
Is TLC27L9IDG4 pin-compatible with other TLC27Lx variants like TLC27L4 or TLC27L4B?
Yes, TLC27L9IDG4 is fully pin-compatible with all TLC27Lx quad op-amps in the SOIC-14 (D) package, including TLC27L4IDG4, TLC27L4BIDG4, and TLC27L4AIDG4. The pinout, footprint, and electrical interface are identical - only the input offset voltage grade and temperature qualification differ, allowing drop-in upgrades for improved DC precision in existing designs.
