Product details
Overview
TLC083IDGQ from Texas Instruments is a dual-channel, wide-bandwidth, high-output-drive operational amplifier designed 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 8.5 nV/√Hz input voltage noise-enabling robust signal conditioning in automotive sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC083IDGQ datasheet, TLC083IDGQ pinout, TLC083IDGQ application, or TLC083IDGQ equivalent, key selection criteria include its rail-to-rail input common-mode range (GND to VDD–2 V), shutdown capability (125 µA/channel), and MSOP-10 PowerPAD™ package optimized for thermal performance in space-constrained designs.
Technical Context
The TLC083IDGQ employs TI's patented LBC3 BiCMOS process, integrating a low-noise CMOS front end with a high-drive bipolar output stage. This architecture enables simultaneous high dc precision (60 µV max input offset) and ac performance (10 MHz GBW, 19 V/µs negative slew rate).
It features independent shutdown control per channel (pins 1 and 8), ground-sensing input common-mode range, and stable operation into capacitive loads up to 50 pF-making it suitable for driving ADC drivers, active filters, and multiplexed sensor signal chains without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 10 MHz - supports stable unity-gain buffer and closed-loop amplification up to ~1 MHz at AV = 10. |
| Output current (sourcing/sinking) | ±57 mA / ±55 mA - drives heavy loads like 600 Ω audio lines or 10 kΩ DAC buffers without external transistors. |
| Input offset voltage | 60 µV - ensures <0.1% error in precision 12-bit+ measurement paths with gain ≤100. |
| Supply current (per channel) | 1.9 mA - enables low-power operation in battery-backed instrumentation with minimal quiescent load. |
| Shutdown current (per channel) | 125 µA - reduces system standby power by >90% when unused channels are disabled. |
| Input voltage noise | 8.5 nV/√Hz - preserves SNR in microphone preamps and strain-gauge amplifiers below 10 kHz. |
| Common-mode input range | GND to VDD–2 V - accepts 0 V referenced signals directly, eliminating level-shifting circuitry in single-supply systems. |
Pinout & Package
Package: 10-pin MSOP PowerPAD™ (DGQ) with exposed thermal pad for enhanced heat dissipation in high-output-drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 shutdown | Active-low logic input; pulls supply current to 125 µA/channel when ≤0.8 V. |
| 2 | Channel 1 inverting input | Inverts signal polarity in standard op-amp configurations; high-impedance CMOS input. |
| 3 | Channel 1 non-inverting input | Accepts input signals from GND to VDD–2 V; no level-shifting required for 0 V referenced sources. |
| 4 | GND | Analog ground reference; connects to PCB thermal pad for optimal thermal performance. |
| 5 | Channel 1 output | Delivers ±57 mA sourcing/sinking; stable into 50 pF capacitive loads without oscillation. |
| 6 | VDD | Single supply rail (4.5–16 V); powers both channels and internal bias circuitry. |
| 7 | Channel 2 output | Independent output; identical drive capability and settling behavior as pin 5. |
| 8 | Channel 2 shutdown | Independent enable/disable control for second channel; supports dynamic power gating. |
| 9 | Channel 2 non-inverting input | Matches pin 3 functionality; enables dual-channel synchronous sensing or filtering. |
| 10 | Channel 2 inverting input | Matches pin 2 functionality; allows matched dual-path signal processing with shared VDD/GND. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (4.5–16 V) | Supports direct integration into 5 V, 12 V, and 15 V industrial and automotive power domains without regulators. |
| High output drive (±57 mA) | Eliminates need for external buffer stages when driving low-impedance loads like piezoelectric sensors or relay coils. |
| Ultralow shutdown current (125 µA/channel) | Enables selective channel disabling in multi-channel data acquisition systems to meet strict system-level power budgets. |
| Ground-sensing input common-mode range | Accepts 0 V referenced inputs (e.g., thermocouples, bridge sensors) without external bias resistors or level shifters. |
| MSOP-10 PowerPAD™ package | Thermally enhanced footprint reduces junction-to-ambient thermal resistance to 52.3°C/W for reliable operation at full output drive. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Lower output drive (±30 mA), lower bandwidth (6.4 MHz), no shutdown pins, SOIC-8 package. | Suitable for low-power, low-speed sensor buffering where thermal performance and channel disable are not critical. | Select TLV2462IDR only if output current <35 mA suffices and MSOP thermal advantages are unnecessary. |
| OPA2350UA | Higher bandwidth (38 MHz), lower noise (7 nV/√Hz), but limited output drive (±30 mA) and no shutdown function. | Better for high-frequency signal conditioning (e.g., ultrasound front-ends), but unsuitable for driving heavy loads or power-gated systems. | Choose OPA2350UA when speed and noise dominate requirements, and output current or shutdown are secondary. |
Compared with TLV2462IDR and OPA2350UA, the TLC083IDGQ uniquely balances high output drive, integrated shutdown, and thermal-efficient MSOP packaging-making it the only option among the three capable of driving 600 Ω loads while supporting dynamic power management in compact industrial enclosures.

FAQ
What is the operating temperature range for the TLC083IDGQ?
The TLC083IDGQ is rated for an extended industrial temperature range of –40°C to +125°C, verified across all electrical parameters in the official TI datasheet SLOS254F. This makes the TLC083IDGQ suitable for under-hood automotive applications and high-temperature industrial control environments where thermal stability is critical. All specifications-including input offset voltage, output drive, and slew rate-are guaranteed across this full range.
Does the TLC083IDGQ support rail-to-rail input or output operation?
The TLC083IDGQ supports rail-to-rail input common-mode voltage (GND to VDD–2 V) but does not provide rail-to-rail output swing. Its output typically swings within 1.5 V of each rail under load, delivering ≥10.3 V high-level and ≤0.65 V low-level output at VDD = 12 V and IOUT = ±50 mA. This behavior is explicitly characterized in the datasheet's VOH/VOL tables and enables robust interfacing with mid-supply-referenced ADCs and comparators.
How does the shutdown feature work on the TLC083IDGQ?
The TLC083IDGQ provides independent active-low shutdown control on pins 1 (CH1) and 8 (CH2). When either pin is pulled ≤0.8 V, the corresponding channel enters ultralow-power mode with supply current reduced to 125 µA/channel (typical), while the other channel remains fully operational. The shutdown response time is 1.3 µs (turnoff) and 0.47 µs (turnon) at VDD = 12 V, enabling precise power gating in multi-channel DAQ systems without disrupting adjacent signal paths.
Can the TLC083IDGQ drive a 600 Ω load at 20 kHz without distortion?
Yes-the TLC083IDGQ maintains <0.005% THD+N at f = 1 kHz and VO(PP) = 8 V into 10 kΩ, and <0.022% at AV = 100. At 20 kHz, its 10 MHz gain-bandwidth and 16 V/µs slew rate support clean 2 VPP output into 600 Ω (3.3 mA peak), confirmed by Figure 29 in the datasheet. For full 20 kHz fidelity at higher amplitudes, use CL ≤ 10 pF and avoid excessive capacitive loading to preserve phase margin.
What is the thermal performance advantage of the MSOP-10 PowerPAD™ package used by the TLC083IDGQ?
The MSOP-10 PowerPAD™ (DGQ) package achieves θJA = 52.3°C/W and θJC = 4.7°C/W-significantly better than standard SOIC-8 (θJA ≈ 122°C/W) or PDIP-14 (θJA ≈ 78°C/W). This allows the TLC083IDGQ to sustain continuous ±55 mA output into 0.5 V loads at 125°C ambient without exceeding 150°C junction limit, making it uniquely suited for thermally constrained industrial modules where passive cooling is limited.
