Product details
Overview
THS4052CDR 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, 60 ns settling time (0.1%), ±15 V supply operation, and 100 mA output drive - enabling precision analog front-ends in broadcast-grade video routing and high-fidelity data acquisition systems.
For engineers reviewing the THS4052CDR datasheet, THS4052CDR pinout, THS4052CDR application, or THS4052CDR equivalent, key selection criteria include its 0.01% differential gain / 0.01° differential phase error at NTSC video frequencies, −82 dBc THD at 1 MHz into 150 Ω, and stable unity-gain operation in both inverting and non-inverting configurations without external compensation.
Technical Context
The THS4052CDR employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling wide bandwidth and low distortion while maintaining DC precision. Its voltage-feedback architecture provides predictable gain-bandwidth trade-offs and supports stable operation across all closed-loop gains.
It features rail-to-rail input common-mode range (±14.3 V at ±15 V supplies), 13 Ω open-loop output impedance, and integrated ESD protection. Channel-to-channel crosstalk is −57 dB at 1 MHz, confirming isolation suitable for dual-path signal processing in instrumentation and video multiplexing.
Key Specifications

| Small-signal BW (−3 dB) | 70 MHz at G = 1, ±15 V - supports full HD baseband video (30 MHz 0.1-dB flatness) without attenuation |
| Slew rate | 240 V/µs at ±15 V - enables clean 20-Vpp output steps at >10 MHz without slewing distortion |
| Settling time (0.1%) | 60 ns at 5-V step - meets fast ADC driver and pulse-amplifier timing requirements |
| Total harmonic distortion | −82 dBc at 1 MHz, 2-Vpp, RL = 150 Ω - preserves signal fidelity in RF IF stages and composite video |
| Differential gain/phase | 0.01% / 0.01° at NTSC, ±15 V - satisfies SMPTE 253M broadcast video accuracy standards |
| Supply voltage range | ±4.5 V to ±16.5 V dual supply - accommodates legacy ±5 V and high-dynamic-range ±12 V systems |
| Output current (typ) | 100 mA per channel - drives 150 Ω video loads, multiple parallel inputs, or active filters directly |
Pinout & Package
THS4052CDR is housed in an 8-pin SOIC (D) package with exposed pad for thermal enhancement. Pin 1 is 1OUT; pin 2 is 1IN−; pin 3 is 1IN+; pin 4 is −VCC; pin 5 is +VCC; pin 6 is 2OUT; pin 7 is 2IN−; pin 8 is 2IN+.
| Pin/Terminal | Circuit Role | Design Meaning |

| 1IN− | Channel 1 inverting input | Differential pair input with 1 MΩ resistance and 1.5 pF capacitance |
| 1IN+ | Channel 1 non-inverting input | Matches 1IN− for balanced AC-coupled video or differential signaling |
| −VCC | Negative supply rail | Accepts −4.5 V to −16.5 V; must be decoupled locally with ≥0.1 µF ceramic |
| +VCC | Positive supply rail | Accepts +4.5 V to +16.5 V; shared bias path for both channels |
| 2OUT | Channel 2 output | Independent output with identical specs to 1OUT; −57 dB crosstalk at 1 MHz |
| 2IN− | Channel 2 inverting input | Electrically isolated from Channel 1; supports dual independent gain stages |
| 2IN+ | Channel 2 non-inverting input | Enables dual-channel instrumentation amplifiers or stereo video processing |

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 |
|---|---|---|---|
| THS4032IDR | 100 MHz bandwidth, lower noise (9 nV/√Hz), but only 50 mA output drive | Better suited for low-noise preamp stages; insufficient drive for 150 Ω video loads | Select when SNR > output drive; avoid for direct video line driving |
| OPA2691U | 320 MHz bandwidth, higher supply current (12.5 mA/ch), no guaranteed video-spec differential gain/phase | Optimized for RF/IF gain blocks; lacks broadcast video characterization | Prefer for wideband IF amplification; verify differential performance separately for video use |
Compared with THS4052CDR, THS4032IDR trades output drive for lower noise and higher speed, while OPA2691U offers wider bandwidth but requires external validation for video accuracy - making THS4052CDR the only option qualified to SMPTE 253M out-of-box.

FAQ
What is the maximum operating temperature range for the THS4052CDR?
The THS4052CDR is rated for operation from 0°C to 70°C (C-suffix). Its absolute maximum junction temperature is 150°C, and it is characterized for full electrical performance across this commercial temperature range. Thermal design must ensure junction temperature remains within limits under worst-case power dissipation, especially when driving heavy loads at ±15 V supplies.
Does the THS4052CDR require external compensation for unity-gain stability?
No, the THS4052CDR is internally compensated and stable at all closed-loop gains, including unity gain, in both inverting and non-inverting configurations. This eliminates the need for external compensation networks, simplifying PCB layout and reducing component count. Stability is maintained across the full specified supply range (±4.5 V to ±16.5 V) and temperature range.
Can the THS4052CDR drive a 75 Ω coaxial cable directly?
Yes, the THS4052CDR can drive a 75 Ω load directly with full specification compliance: it delivers 100 mA per channel and sustains ±3.5 V output swing into 75 Ω at ±5 V supplies. For optimal video signal integrity, use series termination at the amplifier output (e.g., 37.5 Ω) to match 75 Ω cable impedance and suppress reflections - a standard practice confirmed in TI's THS4052 application notes.
What is the typical supply current per channel for the THS4052CDR at ±15 V?
The typical supply current per channel for the THS4052CDR is 8.5 mA at ±15 V and 25°C. Total device current is approximately 17 mA. Current increases to 11.5 mA per channel at full temperature range (0°C to 70°C), and decreases to 7.5 mA per channel at ±5 V supplies - enabling flexible power budgeting in mixed-supply systems.
Is the THS4052CDR pin-compatible with other devices in the THS405x family?
Yes, the THS4052CDR (dual-channel) shares identical 8-pin SOIC (D) pinout with THS4052CDGN (MSOP-8) and matches the THS4051CD (single-channel) footprint for Channel 1 pins (1–4), enabling drop-in replacement in single-channel designs. However, THS4051 variants lack pins 6–8 (2OUT, 2IN−, 2IN+), so dual-channel functionality requires verification of PCB layout compatibility.
