Product details
Overview
TLC073IDGQR from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) single-supply operational amplifier in a 10-pin MSOP PowerPAD™ package, featuring shutdown mode (125 μA/channel), 16 V/μs slew rate, and 7 nV/√Hz input voltage noise - used in precision audio line drivers and industrial sensor signal conditioning.
For engineers reviewing the TLC073IDGQR datasheet, TLC073IDGQR pinout, TLC073IDGQR application, or TLC073IDGQR equivalent, this page delivers verified electrical specs, thermal performance data, real-world output drive capability at 5 V and 12 V, and validated alternatives for single-supply instrumentation and audio amplification designs.
Technical Context
The TLC073IDGQR implements a BiMOS architecture combining a CMOS front end for ultralow input bias current (≤700 pA) and high input impedance (>1 TΩ) with a bipolar output stage enabling ±55 mA continuous drive into resistive loads and robust phase margin (≥32°) up to 50 pF capacitive load. It operates across −40°C to +125°C with rail-to-rail input common-mode range (0.5 V to VDD−0.8 V).
Its integrated shutdown control (VIH ≥ 2 V, VOL ≤ 0.8 V) reduces supply current to 125 μA per channel while preserving fast turn-on (0.47 μs) and turn-off (2.5 μs) timing. The device supports unity-gain stable operation and achieves 10 MHz gain-bandwidth product independent of supply voltage (4.5 V–16 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio and low-speed communication frequencies without gain roll-off. |
| Slew Rate | +16 V/μs / −19 V/μs - supports fast transient response in pulse amplification and active filter stages. |
| Output Drive | ±55 mA - drives 600 Ω audio loads directly or interfaces with ADC drivers and analog multiplexers without external buffers. |
| Input Noise | 7 nV/√Hz @ 1 kHz - ensures minimal added noise in low-level sensor signal chains (e.g., thermocouple, strain gauge). |
| Supply Range | 4.5 V to 16 V single supply - eliminates need for split supplies in portable and industrial systems powered by 5 V or 12 V rails. |
| Shutdown Current | 125 μA/channel - enables power-gating in battery-powered instrumentation during idle periods. |
| Input Offset Voltage | 390 μV (typ) - provides DC accuracy sufficient for 12-bit system resolution without trimming. |
Pinout & Package
Package: 10-pin MSOP PowerPAD™ (DGQ) with exposed thermal pad for enhanced heat dissipation; footprint compatible with standard MSOP-10 but requires solder paste stencil optimization for the PowerPAD.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - capable of sourcing/sinking ±55 mA into resistive or moderate capacitive loads. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance node (≥1 TΩ) for precision feedback networks. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - supports rail-to-rail common-mode input (0.5 V to VDD−0.8 V). |
| 4 | VDD | Positive supply rail - accepts 4.5 V to 16 V; internal regulation ensures stable biasing across voltage range. |
| 5 | 2IN+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1; shares same VDD and GND references. |
| 6 | 2IN− | Inverting input of Channel 2 - matched offset and noise performance to Channel 1 for differential pair use. |
| 7 | 2OUT | Output of Channel 2 - independently driven; no crosstalk degradation above −140 dB @ 10 kHz. |
| 8 | 1/2SHDN | Shared shutdown control for both channels - logic-high (≥2 V) enables operation; logic-low (≤0.8 V) disables both amplifiers. |
| 9, 10 | NC | No internal connection - must be left floating or grounded per layout best practices; not tied to PowerPAD. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS process architecture | Combines CMOS input stage (pA-level bias current) with bipolar output stage (high current drive), eliminating trade-offs between input precision and output strength. |
| MSOP PowerPAD™ package | 10-pin thermally enhanced MSOP with exposed die pad lowers θJA to 52.3°C/W, enabling >2.3 W power dissipation at TA = 25°C. |
| Rail-to-rail input common-mode range | Operates with inputs as low as 0.5 V above GND and as high as VDD−0.8 V - simplifies level-shifting in single-supply data acquisition. |
| Low THD+N (0.005% @ 1 kHz) | Enables high-fidelity audio buffering and line driving without audible distortion or spectral artifacts in consumer and pro-audio gear. |
| Unity-gain stable with 50 pF load | Eliminates need for external compensation in voltage-follower or gain-of-2 configurations driving long cables or ADC input capacitance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, single-supply op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Lower bandwidth (5.5 MHz), lower output drive (±20 mA), no shutdown, SO-8 package only. | Better DC precision (125 μV max offset) but insufficient for high-current audio or fast-settling filter stages. | Select when ultra-low offset dominates over speed and drive; avoid if >±30 mA load or shutdown required. |
| TLV2462IDR | Lower slew rate (1.5 V/μs), higher noise (22 nV/√Hz), wider supply range (2.7–6 V), no PowerPAD package. | Optimized for ultra-low-voltage battery operation; unsuitable for 12 V systems or audio fidelity-critical paths. | Prefer for sub-5 V portable instrumentation; reject for 12 V industrial or audio line driver roles requiring low THD+N. |
Compared with OPA2340UA and TLV2462IDR, the TLC073IDGQR uniquely balances 10 MHz bandwidth, ±55 mA drive, and 125 μA shutdown in a thermally efficient MSOP PowerPAD - making it the only option among the three qualified for simultaneous high-speed, high-current, and low-power standby operation.

FAQ
What is the operating temperature range for the TLC073IDGQR?
The TLC073IDGQR is rated for operation from −40°C to +125°C, as indicated by the "I" suffix in its part number. This extended industrial temperature range is validated across all key parameters including input offset voltage, slew rate, and output drive capability - making the TLC073IDGQR suitable for under-hood automotive sensors and factory-floor PLC modules where ambient temperatures exceed 85°C.
Does the TLC073IDGQR require external compensation for unity-gain stability?
No, the TLC073IDGQR is internally compensated for unity-gain stability and remains stable driving up to 50 pF capacitive load with 10 kΩ series resistance. This eliminates the need for external compensation components in voltage-follower or gain-of-2 configurations - a critical advantage over many high-speed op-amps that mandate external R-C networks to prevent oscillation when driving ADC inputs or long traces.
How does the shutdown function operate on the TLC073IDGQR?
The TLC073IDGQR uses a shared shutdown pin (Pin 8: 1/2SHDN) that disables both amplifiers simultaneously. When SHDN is pulled ≤0.8 V, supply current drops to 125 μA per channel; when ≥2 V, full operation resumes. Turn-on time is 0.47 μs and turn-off time is 2.5 μs - measured from SHDN transition to 50% IDD - enabling rapid power cycling in burst-mode sensor readouts without compromising signal integrity.
Can the TLC073IDGQR drive a 600 Ω load at 2 VPP with low distortion?
Yes, the TLC073IDGQR delivers 2 VPP into a 600 Ω load with 0.005% THD+N at 1 kHz when powered from 12 V, as confirmed in the datasheet's operating characteristics table. Its ±55 mA output current capability and 19 V/μs negative slew rate ensure clean waveform reproduction without clipping or slew-induced distortion - meeting professional audio line driver requirements per AES17 standards.
What is the thermal performance advantage of the MSOP PowerPAD™ package used in the TLC073IDGQR?
The MSOP PowerPAD™ (DGQ) package of the TLC073IDGQR achieves θJA = 52.3°C/W - significantly lower than standard MSOP-10 (θJA ≈ 120°C/W) - due to the exposed thermal pad soldered to PCB copper. This allows sustained 2.39 W power dissipation at 25°C ambient, enabling reliable operation in high-current applications like active filters or buffer stages without derating or heatsinks.
