Product details
Overview
THS4222DR from Texas Instruments is a dual, rail-to-rail output, voltage-feedback operational amplifier optimized for high-speed, low-distortion signal conditioning in data converter interfaces and video systems. It delivers 230 MHz small-signal bandwidth (G=1), 975 V/µs slew rate, −90 dBc HD2 and −100 dBc HD3 at 5 MHz (RL=499 Ω), and ±4.8 V output swing into 2 kΩ on ±5 V supplies.
For engineers reviewing the THS4222DR datasheet, THS4222DR pinout, THS4222DR application, or THS4222DR equivalent, key selection criteria include its dual-channel rail-to-rail output stage, 14 mA/channel quiescent current, 0.007% differential gain/0.007° differential phase for NTSC/PAL video, and compatibility with 3 V to 15 V single or dual supplies.
Technical Context
The THS4222DR implements a voltage-feedback architecture with unity-gain stability and a fully differential output stage capable of driving 499 Ω loads while maintaining <0.1 dB flatness to 40 MHz. Its input stage supports common-mode range from VS− + 1.1 V to VS+ − 1.1 V under dual supply, and 1.1 V to 3.9 V under 5 V single supply.
It features matched internal channels with −90 dB crosstalk at 5 MHz, 33 MΩ input resistance, and 1/0.5 pF common-mode/differential input capacitance - enabling precise active filtering and ADC driver applications without external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2691ID | Higher 500 MHz bandwidth and 1800 V/µs slew rate; higher 22 mA/channel IQ; no rail-to-rail output (clips ~1.2 V from rails) | Better suited for >100 MHz IF amplification but requires level-shifting for full-rail ADC interfacing | Select when bandwidth >300 MHz is mandatory and output swing margin can be sacrificed |
| LMH6629MA/NOPB | Lower 1.5 GHz bandwidth but higher 900 V/µs slew rate; 10 nV/√Hz input noise; rail-to-rail input/output; 12 mA/channel IQ | Superior noise performance and wider input common-mode range (rail-to-rail), but lower HD3 (−85 dBc @ 5 MHz) | Select when ultra-low noise dominates over harmonic distortion in sensor front-ends |
Compared with OPA2691ID and LMH6629MA/NOPB, THS4222DR uniquely balances 230 MHz bandwidth, rail-to-rail output, −100 dBc HD3, and 14 mA power - making it optimal for cost-sensitive, space-constrained video and mid-speed ADC driver applications where full output swing and low distortion are jointly critical.

FAQ
What is the maximum supply voltage rating for THS4222DR?
The absolute maximum supply voltage for THS4222DR is ±8.25 V (16.5 V total) for dual supply, or 16.5 V for single supply. Operation beyond this risks permanent damage. The recommended operating range is ±1.35 V to ±7.5 V dual or 2.7 V to 15 V single supply, with 14 mA typical quiescent current per channel at ±5 V.
Does THS4222DR support single-supply operation?
Yes, THS4222DR supports true single-supply operation from 2.7 V to 15 V. At 5 V supply, it delivers 0.1 V to 4.9 V output swing into 2 kΩ, with input common-mode range from 1.1 V to 3.9 V. Biasing networks (e.g., VREF = VS/2) are required to center AC signals within this range for full rail-to-rail utilization.
What is the thermal performance of THS4222DR in SOIC (D) package?
In the 8-pin SOIC (D) package, THS4222DR has ΘJA = 97.5°C/W and ΘJC = 38.3°C/W. At 14 mA/channel and ±5 V supply, power dissipation is ~140 mW per channel. With proper PCB copper area and airflow, junction temperature remains below 125°C - the point where distortion begins to increase significantly.
Is THS4222DR pin-compatible with THS4226DGQ?
No, THS4222DR (SOIC-8) is not pin-compatible with THS4226DGQ (MSOP-10). THS4222DR uses pins 1–5 and 7–8 for dual-channel I/O and supplies; THS4226DGQ adds dedicated power-down (PD) and reference (REF) pins (pins 5 and 10), altering the pin mapping. Board redesign is required for substitution.
What layout practices improve THS4222DR stability in high-frequency applications?
For optimal THS4222DR stability: place 0.1 µF ceramic decoupling capacitors ≤5 mm from each VS+ and VS− pin; use ground planes beneath the device; route feedback paths short and direct; avoid vias in signal traces; and isolate input and output traces. TI recommends 1.3 kΩ feedback resistors for G=2 configurations to balance bandwidth, noise, and loading.
