Product details
Overview
TLC082IDGN from Texas Instruments is a dual-channel, wide-bandwidth, high-output-drive operational amplifier optimized for single-supply operation across 4.5 V to 16 V. It delivers 10 MHz gain-bandwidth, ±57 mA output drive, 16 V/µs positive slew rate, and 60 µV input offset voltage - enabling precision signal conditioning in automotive sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC082IDGN datasheet, TLC082IDGN pinout, TLC082IDGN application, or TLC082IDGN equivalent, key selection criteria include its rail-to-rail input capability (VICR = GND to VDD–2 V), low 8.5 nV/√Hz input noise, and MSOP-8 PowerPAD™ package with thermal performance rated at θJA = 52.7°C/W - critical for space-constrained, thermally demanding designs.
Technical Context
The TLC082IDGN employs TI's patented LBC3 BiCMOS process, integrating a low-noise CMOS front end (1000 GΩ differential input resistance, 0.6 fA/√Hz input current noise) with a high-current bipolar output stage. This architecture enables simultaneous high dc precision and robust ac performance under heavy capacitive loads.
It operates across –40°C to +125°C, supports true single-supply operation without input common-mode range restrictions near ground, and maintains stable closed-loop behavior up to 50 pF load capacitance (37° phase margin at 12 V). No shutdown functionality is integrated - distinguishing it from TLC080/TLC083 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - supports stable unity-gain buffer or gain-of-10 amplification up to 1 MHz without peaking. |
| Input offset voltage | 60 µV max - enables sub-mV-level dc accuracy in 12-bit data acquisition systems without trimming. |
| Output drive current | ±57 mA - drives 50-Ω transmission lines or multiple parallel ADC inputs directly without external buffers. |
| Slew rate (SR+) | 16 V/µs - settles 10-V step in <0.2 µs at 0.1% error, suitable for fast pulse conditioning. |
| Supply voltage range | 4.5 V to 16 V - compatible with 5 V, 12 V, and unregulated industrial rails without LDO pre-regulation. |
| Input noise voltage | 8.5 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and strain-gauge bridges with <100-kΩ source impedances. |
| Common-mode input range | GND to VDD–2 V - accepts 0–5 V sensor outputs on 5 V supply with full linear operation. |
Pinout & Package
Package: 8-pin MSOP (DGN) with exposed thermal pad (PowerPAD™); body dimensions 3.0 mm × 3.0 mm × 1.0 mm; RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | High-impedance node accepting feedback or signal inversion; requires matched trace routing for optimal CMRR. |
| 2 | Non-inverting input (Channel 1) | DC-coupled input capable of operating down to GND; bias current <100 pA minimizes resistor-induced offset. |
| 3 | Output (Channel 1) | Capable of sourcing/sinking ±57 mA into resistive or moderate capacitive loads; thermal pad must be soldered for rated power dissipation. |
| 4 | Ground | Primary reference for both channels; separate ground plane connection recommended to avoid crosstalk. |
| 5 | VDD | Single positive supply input; decoupling capacitor (0.1 µF ceramic + 4.7 µF tantalum) required within 5 mm. |
| 6 | Output (Channel 2) | Independent output stage with identical drive specs; layout symmetry critical to minimize inter-channel coupling. |
| 7 | Inverting input (Channel 2) | Electrically isolated from Channel 1 inputs; no internal connection to Pin 1 or Pin 2. |
| 8 | Non-inverting input (Channel 2) | Full rail-to-rail common-mode range; usable as reference buffer for ADC VREF or DAC IOUT. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS process architecture | Combines 1000 GΩ CMOS input impedance with bipolar output stage delivering ±57 mA - eliminates need for discrete output buffers in driver applications. |
| Wide supply range (4.5–16 V) | Operates directly from 5 V logic rails or 12 V industrial buses without level-shifting or regulation - reduces BOM count by one regulator. |
| Low input noise (8.5 nV/√Hz) | Enables 16-bit effective resolution in 100-kSPS data loggers with 10-kΩ sensor sources, avoiding costly chopper-stabilized alternatives. |
| Rail-to-rail input (GND to VDD–2 V) | Accepts 0–5 V signals on 5 V supply without external level shifters - simplifies interface to microcontroller ADCs and digital sensors. |
| MSOP-8 PowerPAD™ package | Thermal resistance θJA = 52.7°C/W enables 2.37 W power dissipation - supports continuous high-current operation in compact enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower bandwidth (6.4 MHz), lower output drive (±30 mA), higher supply current (550 µA/channel), but includes rail-to-rail output swing. | Better suited for low-power, battery-operated devices where output swing to rails is mandatory. | Select TLV2462IDR when rail-to-rail output is required and bandwidth <7 MHz suffices; avoid if driving >30 mA loads. |
| OPA2350UA | Higher bandwidth (38 MHz), lower noise (7 nV/√Hz), but narrower supply range (2.7–5.5 V) and lower output drive (±50 mA). | Ideal for high-speed, low-voltage portable instrumentation requiring fast settling and ultra-low noise. | Choose OPA2350UA for 3.3 V systems needing >30 MHz bandwidth; not viable for 12 V industrial rails. |
Compared with TLV2462IDR and OPA2350UA, the TLC082IDGN uniquely balances 10 MHz bandwidth, ±57 mA drive, and 4.5–16 V operation - making it the only dual op-amp in this group capable of direct 12 V sensor excitation and high-current line driving without auxiliary circuitry.

FAQ
What is the operating temperature range for the TLC082IDGN?
The TLC082IDGN is specified for operation from –40°C to +125°C, meeting extended industrial temperature requirements. This rating is confirmed in the "Recommended Operating Conditions" table of the SLOS254F datasheet, and applies to all electrical characteristics unless otherwise noted. The I-suffix designation in TLC082IDGN explicitly denotes this extended temperature grade, ensuring reliability in under-hood automotive and factory-floor environments where ambient temperatures exceed standard commercial limits.
Does the TLC082IDGN include a shutdown feature?
No, the TLC082IDGN does not include a shutdown pin or mode. Unlike the TLC080 and TLC083 variants (which feature SHDN pins), the TLC082 is a dual-channel op-amp without integrated power-down functionality. Its supply current remains at 1.9–2.9 mA per channel across the full supply range (4.5–16 V) and temperature span. This design choice prioritizes simplicity and output drive capability over quiescent power reduction.
What is the maximum capacitive load the TLC082IDGN can drive stably?
The TLC082IDGN maintains stability with up to 50 pF of capacitive load, achieving 37° phase margin at 12 V supply (per Figure 19 in SLOS254F). For loads exceeding 50 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is required to prevent peaking or oscillation. This capability supports direct driving of ADC input capacitors and long PCB traces without added compensation networks.
Is the TLC082IDGN pin-compatible with other TLC08x variants in MSOP-8 packages?
Yes, the TLC082IDGN shares identical pinout and footprint with TLC080IDGN and TLC081IDGN in the MSOP-8 (DGN) package, as confirmed by the "TLC082 D, DGN, OR P PACKAGE (TOP VIEW)" diagram in the datasheet. However, functional compatibility is limited: TLC080 includes shutdown and null pins, while TLC082 has no SHDN or NULL connections - requiring schematic review before substitution.
What thermal considerations apply to the TLC082IDGN's MSOP-8 PowerPAD™ package?
The TLC082IDGN's MSOP-8 PowerPAD™ package achieves θJA = 52.7°C/W only when the exposed thermal pad is soldered to a minimum 100 mm² copper pour on the PCB. Without proper pad connection, thermal resistance degrades significantly, limiting safe continuous power dissipation to <500 mW. TI recommends using 4–6 thermal vias (0.3 mm diameter) beneath the pad connected to an internal ground plane for optimal heat transfer in high-current applications.
