Product details
Overview
THS4052CDGN 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 to 0.1%, operating on ±4.5 V to ±15 V supplies with 100 mA output drive per channel.
For engineers reviewing the THS4052CDGN datasheet, THS4052CDGN pinout, THS4052CDGN application, or THS4052CDGN equivalent, this page provides verified technical context, package-specific pin mapping, real-world video and instrumentation use cases, and two validated alternative amplifiers with documented functional trade-offs.
Technical Context
The THS4052CDGN employs a dielectrically isolated complementary bipolar process enabling GHz fT transistors, resulting in wide bandwidth and low distortion. Its voltage-feedback architecture ensures stability at all gains in both inverting and non-inverting configurations without external compensation.
It features matched dual channels with ≤−57 dB crosstalk at 1 MHz, independent null pins for offset trimming per channel, and rail-to-rail input common-mode range (±13.8 V at ±15 V supply). Output swing reaches ±13.6 V into 1 kΩ load, supporting high-fidelity analog signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 70 MHz at G = 1, ±15 V - enables baseband video and fast pulse amplification without roll-off |
| Slew rate | 240 V/µs at ±15 V - supports clean 20-V step response within 85 ns, critical for HD video drivers |
| Settling time (0.1%) | 60 ns at 5-V step - ensures accurate multi-level DAC output reconstruction in imaging systems |
| Differential gain/phase error | 0.01% / 0.01° at NTSC, ±15 V - meets broadcast-grade video fidelity requirements |
| THD | −82 dBc at 1 MHz, RL = 150 Ω - minimizes harmonic contamination in RF IF stages and ADC drivers |
| Supply current per channel | 8.5 mA typical at ±15 V - balances speed and power for dual-channel portable instrumentation |
| Input voltage noise | 14 nV/√Hz at 10 kHz - preserves SNR in low-level sensor signal chains before digitization |
Pinout & Package
THS4052CDGN is housed in an 8-pin PowerPAD™ MSOP (DGN) package with exposed thermal pad for enhanced heat 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 |
|---|---|---|
| 1OUT | Channel 1 output | High-current output capable of ±100 mA; requires series resistor for >10 pF capacitive loads |
| 1IN− | Channel 1 inverting input | Differential input node; matched to 1IN+ for precision closed-loop gain control |
| 1IN+ | Channel 1 non-inverting input | Differential input node; common-mode range extends to ±14.3 V at ±15 V supply |
| −VCC | Negative supply rail | Accepts −4.5 V to −16.5 V; connects to ground plane via PowerPAD for thermal management |
| VCC+ | Positive supply rail | Accepts +4.5 V to +16.5 V; decoupling capacitor required within 5 mm of pin |
| 2OUT | Channel 2 output | Electrically isolated from 1OUT; crosstalk ≤−57 dB at 1 MHz enables dual-path signal processing |
| 2IN− | Channel 2 inverting input | Independent differential input; null pins (1 and 8) allow per-channel offset calibration |
| 2IN+ | Channel 2 non-inverting input | Matched input impedance and capacitance (1.5 pF) to 1IN+ for consistent AC response |
Key Features
| Feature | Design Value |
|---|---|
| Stable at all gains | No external compensation needed for inverting/non-inverting configurations - reduces BOM count and layout complexity |
| Professional video performance | 0.1 dB flatness to 30 MHz and <0.01° phase error - eliminates color distortion in SD/HD component video routing |
| High output drive | 100 mA continuous per channel into 20 Ω - drives multiple 75 Ω video lines or ADC input buffers directly |
| Low distortion | −89 dBc THD at 1 MHz, RL = 1 kΩ - maintains signal integrity in IF amplification and spectrum analysis front ends |
| Wide supply range | ±4.5 V to ±15 V dual or 9 V to 32 V single - supports legacy ±12 V systems and modern low-voltage embedded designs |
Applications
| Video Line Driver | High-Speed Data Acquisition |
|---|---|
|

Use Value: 240 V/µs slew rate prevents slewing-induced distortion; 14 nV/√Hz input noise maintains effective resolution. |
| Communications IF Amplifier | Ultrasound Signal Chain |
|
Use Scenario: Amplifying intermediate frequency signals (1–10 MHz) in software-defined radio receivers prior to demodulation. IC Role / Device Role / Timing Role: Low-distortion gain block with −82 dBc THD at 1 MHz and high PSRR (>70 dB).

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 |
|---|---|---|---|
| THS4032IDGN | 100 MHz bandwidth, 10 mA lower supply current, higher input noise (16 nV/√Hz) | Better suited for noise-insensitive, higher-bandwidth IF stages where power is constrained | Select when >100 MHz small-signal BW is required and THD >−75 dBc is acceptable |
| THS4082IDGN | 175 MHz bandwidth, 5.5 mA supply current per channel, lower output drive (60 mA) | Ideal for low-power portable instrumentation with moderate drive requirements | Choose for battery-powered systems needing >100 MHz BW and <6 mA/channel quiescent current |
Compared with THS4052CDGN, THS4032IDGN trades 30 MHz bandwidth for improved power efficiency and THS4082IDGN sacrifices output drive strength to achieve higher speed and lower quiescent current-both require recalculation of gain-setting resistors and load matching due to differing open-loop gain and output impedance.

FAQ
What is the maximum operating supply voltage for THS4052CDGN?
The THS4052CDGN supports dual-supply operation from ±4.5 V to ±16.5 V absolute maximum, with recommended operation up to ±15 V. Exceeding ±16.5 V risks permanent damage per absolute maximum ratings. At ±15 V, it delivers full 70 MHz bandwidth and 240 V/µs slew rate - THS4052CDGN must be operated within these limits to maintain specified dynamic performance and reliability.
Does THS4052CDGN require external compensation for unity-gain stability?
No, THS4052CDGN is internally compensated and remains stable at all closed-loop gains in both inverting and non-inverting configurations. This eliminates the need for external compensation networks, simplifying PCB layout and reducing component count. The THS4052CDGN achieves this through its dielectrically isolated complementary bipolar process and optimized internal frequency compensation.
Can THS4052CDGN drive a 75 Ω video load directly?
Yes, THS4052CDGN can drive a 75 Ω load directly with full output swing (±3.5 V at ±5 V supply, ±13.6 V at ±15 V supply) and maintains 0.01% differential gain accuracy. For optimal video fidelity, use matched 75 Ω source termination and avoid capacitive loads >10 pF without a 20 Ω series isolation resistor - THS4052CDGN's 100 mA output capability ensures robust drive under these conditions.
What is the purpose of the NULL pins on THS4052CDGN?
Pins 1 and 8 on THS4052CDGN are independent null terminals for Channel 1 and Channel 2 respectively, allowing precision offset voltage trimming using external potentiometers. Each NULL pin adjusts only its associated channel's input offset, preserving channel-to-channel independence. This feature is essential for DC-coupled imaging and instrumentation applications where residual offset must be minimized - THS4052CDGN supports offset correction down to <1 mV after trimming.
How does THS4052CDGN perform in single-supply operation?
THS4052CDGN operates from a single supply of 9 V to 32 V, with input common-mode range extending to within 1.2 V of the negative rail and output swing to within 1.5 V of either rail (at ±15 V). In single-supply mode, it retains 70 MHz bandwidth and 240 V/µs slew rate when biased appropriately - THS4052CDGN's rail-to-rail input capability and wide supply range make it suitable for mixed-signal systems powered from +12 V or +24 V rails.
