Product details
Overview
TLC081IDGNR from Texas Instruments is a single-channel BiMOS operational amplifier optimized for wide-bandwidth, high-output-drive, single-supply applications. It delivers 10 MHz gain-bandwidth, ±57 mA output drive, 16 V/µs positive slew rate, and operates from 4.5 V to 16 V across –40°C to 125°C - enabling use in industrial sensor signal conditioning and audio line drivers.
For engineers reviewing the TLC081IDGNR datasheet, TLC081IDGNR pinout, TLC081IDGNR application, or TLC081IDGNR equivalent, key selection criteria include its rail-to-rail input common-mode range (GND to VDD–2 V), ultralow 125 µA shutdown current per channel, and MSOP-8 PowerPAD™ package thermal performance.
Technical Context
The TLC081IDGNR integrates a low-noise CMOS front end with a high-current bipolar output stage in TI's LBC3 BiCMOS process, enabling simultaneous high input impedance (>1 GΩ differential) and robust output drive (±55 mA min at 0.5 V/ VDD–1.5 V). Its architecture supports stable operation with capacitive loads up to 50 pF without external compensation.
Unlike legacy TL08x predecessors, it features guaranteed ground-sensing input common-mode range, 60 µV typical input offset voltage, and 8.5 nV/√Hz input voltage noise - making it suitable for precision DC-coupled amplification and fast settling (<0.5 µs to 0.1%) in data acquisition front ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - supports closed-loop gain ≥10 at audio and control loop frequencies |
| Output Drive | ±55 mA min - drives 600 Ω loads directly without external buffers |
| Slew Rate | 16 V/µs (SR+) / 19 V/µs (SR–) - enables <0.5 µs large-signal settling for 1 V step |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and battery-backed industrial rails |
| Input Offset | 60 µV typ - reduces DC error in precision transducer amplifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Single-supply rail-to-rail I/O, lower 5.5 MHz bandwidth, 200 µA quiescent current | Better DC precision (10 µV VIO), but insufficient output drive (25 mA) for heavy loads | Select when ultra-low offset dominates over speed and drive capability |
| LM7321MA | Higher 20 MHz bandwidth, 80 mA output drive, but 2.5 mA supply current and no shutdown | Superior AC performance and drive, but lacks low-power sleep mode for battery systems | Select when continuous high-speed operation outweighs shutdown requirement |
Compared with OPA2340UA and LM7321MA, the TLC081IDGNR uniquely balances 10 MHz bandwidth, ±55 mA drive, and 125 µA shutdown current in an MSOP-8 PowerPAD™ package - making it optimal for space-constrained industrial systems requiring both performance and power efficiency.

FAQ
What is the operating temperature range for the TLC081IDGNR?
The TLC081IDGNR is rated for operation from –40°C to +125°C, meeting extended industrial temperature requirements. This range is confirmed by TI's official datasheet SLOS254F revision December 2011, where the "I" suffix denotes the –40°C to 125°C grade, and all electrical characteristics are specified across this full range unless otherwise noted.
Does the TLC081IDGNR support true rail-to-rail input operation?
The TLC081IDGNR supports common-mode input voltage (VICR) from GND to VDD–2 V - meaning it includes ground in its input range but does not reach the positive rail. This "ground-sensing" capability enables direct interfacing with 0–5 V sensors, though it is not a full rail-to-rail input amplifier. The datasheet explicitly states VICR = GND to VDD–2 V under Recommended Operating Conditions.
What is the purpose of Pins 1 and 8 labeled NULL on the TLC081IDGNR?
Pins 1 and 8 of the TLC081IDGNR are designated NULL - they have no internal connection and serve no electrical function. Per TI's datasheet pin diagram and package documentation, these pins must be left unconnected (floating) or optionally tied to GND for mechanical stability; neither connection affects device operation or performance.
Can the TLC081IDGNR drive a 600 Ω load at full output swing?
Yes, the TLC081IDGNR can drive a 600 Ω load to near-rail output swing: at VDD = 12 V, VOH ≥10.3 V (at –35 mA) and VOL ≤0.6 V (at 35 mA), delivering >10 VPP into 600 Ω. This is verified in the Electrical Characteristics table (VDD = 12 V section) and confirmed by typical output voltage vs. current curves (Figures 7 and 8) in the TI datasheet SLOS254F.
Is the TLC081IDGNR pin-compatible with the TLC081CDGNR?
Yes, the TLC081IDGNR and TLC081CDGNR share identical MSOP-8 (DGN) package footprints and pinouts - differing only in temperature grade (I: –40°C to 125°C vs. C: 0°C to 70°C) and tested specifications. Both follow the same pin configuration shown in the "TLC081 D, DGN, OR P PACKAGE (TOP VIEW)" diagram, with Pins 1/NULL, 2/IN–, 3/IN+, 4/GND, 5/NC, 6/VDD, 7/OUT, 8/NULL.
