Product details
Overview
THS4052CDGNR from Texas Instruments is a dual-channel, high-speed voltage-feedback operational amplifier optimized for video, imaging, and communication signal conditioning. It delivers 70 MHz small-signal bandwidth (G = 1), 240 V/µs slew rate, and 60 ns settling time (0.1%), with ±15 V dual-supply operation and 100 mA output drive per channel - enabling high-fidelity analog signal amplification in professional video routing and ADC driver stages.
For engineers reviewing the THS4052CDGNR datasheet, THS4052CDGNR pinout, THS4052CDGNR application, or THS4052CDGNR equivalent, this page provides verified electrical specifications, MSOP-8 package terminal mapping, video-optimized performance metrics (0.01% differential gain, 30 MHz 0.1-dB flatness), and validated alternative options for high-speed op-amp selection in precision analog systems.
Technical Context
The THS4052CDGNR employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling wide bandwidth and low distortion in a voltage-feedback architecture. Its internal compensation ensures stability at all gains in both inverting and non-inverting configurations without external compensation components.
Designed for demanding analog signal paths, it supports dual ±4.5 V to ±15 V supplies or single 9–32 V operation, features rail-to-rail input common-mode range (±14.3 V at ±15 V supply), and maintains low THD (−82 dBc at 1 MHz, RL = 150 Ω) and exceptional video fidelity (0.01° differential phase error).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 70 MHz at G = 1, ±15 V - enables baseband video and IF signal amplification up to NTSC/PAL bandwidths. |
| Slew rate | 240 V/µs at ±15 V - supports fast transient response for pulse and composite video signals without slew-induced distortion. |
| 0.1-dB flatness BW | 30 MHz at G = 1 - ensures amplitude accuracy across SD/HD video spectrum (up to 1080i). |
| Total harmonic distortion | −82 dBc at 1 MHz, RL = 150 Ω - meets broadcast-grade video SNR requirements with minimal spectral contamination. |
| Output current (per channel) | 100 mA typical - drives 150 Ω video loads, multiple downstream inputs, or ADC input buffers directly. |
| Supply voltage range | ±4.5 V to ±15 V dual or 9–32 V single - compatible with legacy ±12 V, ±15 V, and modern 12 V/24 V industrial rails. |
| Differential gain/phase error | 0.01% / 0.01° at NTSC, ±15 V - preserves color fidelity in professional video distribution and encoding systems. |
Pinout & Package
THS4052CDGNR is housed in an 8-pin PowerPAD™ MSOP (DGN) package with exposed thermal pad for enhanced power dissipation. The package measures 3.0 mm × 3.0 mm × 1.0 mm and supports reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | High-current, low-distortion output node; requires 20 Ω series resistor when driving >10 pF capacitive load. |
| 2 (IN1−) | Channel 1 inverting input | Differential input node; matched impedance critical for noise rejection and gain accuracy in inverting configurations. |
| 3 (IN1+) | Channel 1 non-inverting input | High-impedance input node; common-mode range extends to ±14.3 V at ±15 V supply. |
| 4 (VCC−) | Negative supply rail | Connects to system ground or negative rail; decoupling capacitor (0.1 µF) required within 5 mm. |
| 5 (VCC+) | Positive supply rail | Accepts +4.5 V to +15 V (dual) or +9 V to +32 V (single); bypass with 0.1 µF ceramic + 4.7 µF tantalum. |
| 6 (OUT2) | Channel 2 output | Independent high-drive output; channel-to-channel crosstalk is −57 dB at 1 MHz - suitable for dual-path video or I/Q signal chains. |
| 7 (IN2−) | Channel 2 inverting input | Electrically isolated from Channel 1 inputs; enables independent gain setting and feedback networks. |
| 8 (IN2+) | Channel 2 non-inverting input | Matches IN1+ characteristics; allows synchronous dual-channel operation without inter-channel coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Stable at all gains | No external compensation required for unity-gain or high-gain inverting/non-inverting configurations - reduces BOM count and layout complexity. |
| Low differential phase error | 0.01° at NTSC, ±15 V - preserves chrominance timing integrity in broadcast video amplifiers and scan converters. |
| High output drive | 100 mA per channel into 20 Ω - eliminates need for external buffer stages when driving coaxial cables or multiple 150 Ω loads. |
| Wide supply range | Operates from ±4.5 V to ±15 V dual or 9–32 V single - simplifies integration into mixed-voltage systems (e.g., 12 V embedded vision platforms). |
| Thermal-enhanced MSOP | PowerPAD™ thermal pad lowers θJA to 58.4°C/W - enables 2.14 W power dissipation at TA = 25°C, supporting continuous high-output operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4032IDGNR | 100 MHz bandwidth, 12 nV/√Hz input voltage noise (vs. 14 nV/√Hz), lower power (6.5 mA/ch), but reduced output drive (60 mA). | Better suited for low-noise, medium-bandwidth applications (e.g., sensor signal chains); less ideal for 150 Ω video drive. | Select when noise performance outweighs output current; verify load compatibility and thermal margin in MSOP-8. |
| THS4082IDGNR | 175 MHz bandwidth, 12.5 mA/ch supply current, 100 mA output drive, but higher THD (−75 dBc at 1 MHz, RL = 150 Ω). | Optimized for wider bandwidth at cost of video-grade distortion; better for RF IF amplification than broadcast video. | Choose for >100 MHz signal paths where 0.01% differential gain is not required; confirm PSRR and CMRR meet system EMI targets. |
Compared with THS4052CDGNR, THS4032IDGNR trades bandwidth and drive strength for lower noise and power, while THS4082IDGNR prioritizes speed over distortion - making THS4052CDGNR the optimal balance for video-critical, dual-channel, high-fidelity analog amplification.

FAQ
What is the maximum operating temperature range for the THS4052CDGNR?
The THS4052CDGNR is specified for operation from 0°C to 70°C (C-suffix). This commercial-grade temperature range is validated across all key parameters including bandwidth, THD, and output swing. For extended temperature operation (−40°C to 85°C), the THS4052IDGNR variant is available - the THS4052CDGNR itself is not rated beyond 70°C ambient.
Does the THS4052CDGNR require external compensation for unity-gain stability?
No, the THS4052CDGNR is internally compensated and remains stable at all closed-loop gains, including unity gain, in both inverting and non-inverting configurations. This eliminates the need for external compensation networks, reducing design complexity and board space. Stability is guaranteed per TI's characterization across the full operating temperature and supply range.
Can the THS4052CDGNR drive a 75 Ω coaxial cable directly?
Yes - with proper layout. The THS4052CDGNR delivers 100 mA per channel and can drive 75 Ω loads, but a 20 Ω series resistor must be placed at the output pin to isolate the amplifier from cable capacitance and prevent peaking or oscillation. This configuration is validated in TI's application notes for video line drivers and matches standard 75 Ω source termination practices.
What is the purpose of Pins 1 and 8 labeled "NULL" in the THS4052CDGNR pinout?
Pins 1 and 8 on the THS4052CDGNR are no-connect (NC) terminals - they have no internal connection and must remain unconnected. These pins are reserved for future device variants or test functions and carry no electrical function in the THS4052CDGNR. Do not tie them to ground, supply, or any other node.
How does the THS4052CDGNR's PowerPAD™ enhance thermal performance compared to standard MSOP?
The THS4052CDGNR's PowerPAD™ is an exposed copper thermal pad on the underside of the MSOP-8 package, soldered directly to a PCB copper pour. This reduces θJA to 58.4°C/W (vs. ~167°C/W for SOIC-8), enabling 2.14 W power dissipation at 25°C ambient - critical for sustained high-output operation in video and instrumentation applications where thermal derating would otherwise limit performance.
