Texas Instruments TLC080IDGNR

Overview

TLC080IDGNR from Texas Instruments is a single-channel, wide-bandwidth BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V), delivering 10 MHz gain-bandwidth, ±57 mA output drive, and 16 V/µs positive slew rate. It features shutdown capability, rail-to-rail input common-mode range (including ground), and is used in high-fidelity audio line drivers, industrial sensor signal conditioning, and automotive body control modules requiring robust output current and low noise.

For engineers reviewing the TLC080IDGNR datasheet, TLC080IDGNR pinout, TLC080IDGNR application, or TLC080IDGNR equivalent, key selection criteria include its guaranteed –40°C to 125°C industrial temperature rating, MSOP-8 PowerPAD™ package thermal performance, ultralow 125 µA/channel shutdown current, and compatibility with 5 V and 12 V single-rail systems without level-shifting circuitry.

Technical Context

The TLC080IDGNR employs TI's LBC3 BiCMOS process, integrating a low-noise CMOS front end (8.5 nV/√Hz input voltage noise) with a high-drive bipolar output stage. Its internal architecture supports true single-supply operation with VICR extending to GND and VDD–2 V, enabling direct interfacing with microcontroller ADCs and DACs.

It includes dedicated shutdown (SHDN) logic referenced to GND, with defined VIH = 2 V and VIL = 0.8 V thresholds, and features offset nulling pins (NULL) for precision DC applications. The device maintains stability driving capacitive loads up to 50 pF at unity gain, with phase margin ≥32° under typical conditions.

Key Specifications

Pinout & Package

The TLC080IDGNR is housed in an 8-pin MSOP PowerPAD™ package (DGN), featuring exposed thermal pad for enhanced heat dissipation (θJC = 4.7°C/W). The PowerPAD must be soldered to PCB copper for rated performance.

FAQ

What is the operating temperature range for the TLC080IDGNR?

The TLC080IDGNR is rated for –40°C to +125°C, meeting industrial and automotive under-hood requirements. This I-suffix grade guarantees all electrical specifications-including input offset voltage, output drive, and slew rate-across the full range, unlike commercial-grade variants limited to 0°C–70°C.

Does the TLC080IDGNR require external components for stable operation?

Yes, the TLC080IDGNR requires a 0.1 µF ceramic decoupling capacitor between VDD and GND, placed within 2 mm of the pins. For unity-gain stable configurations driving >50 pF capacitive loads, a small series resistor (10–50 Ω) at the output is recommended to maintain phase margin ≥32°.

How does the shutdown function work on the TLC080IDGNR?

The TLC080IDGNR's SHDN pin (Pin 5) is an active-low logic input. When pulled ≤0.8 V (VIL), it disables the amplifier core and reduces supply current to 125 µA per channel. When pulled ≥2 V (VIH), normal operation resumes with 1.9 mA typical supply current. No external pull-up is required if driven by a microcontroller GPIO.

Can the TLC080IDGNR drive a 600 Ω load at 2 V_PP with low distortion?

Yes-the TLC080IDGNR delivers ±57 mA output current and achieves THD+N <0.012% at 1 kHz into 10 kΩ, and <0.085% into 250 Ω. At 2 V_PP into 600 Ω, distortion remains below 0.05%, validated by TI's Figure 29 and 30 test data across 5 V and 12 V supplies.

Is the MSOP PowerPAD™ pad on the TLC080IDGNR electrically connected internally?

No-the exposed thermal pad on the TLC080IDGNR is not electrically connected to any internal node. It must be soldered to a PCB thermal plane (ideally tied to GND for shielding) to achieve the specified θJC = 4.7°C/W and prevent thermal derating above 85°C ambient.
