Active production — no obsolescence risk for this BOM line
The THS4221DBVR is an active-production voltage-feedback op-amp from Texas Instruments, listed with current lifecycle status.
990V/µs slew rate and 230 MHz bandwidth — what they mean for signal fidelity
For smaller signals the -3dB bandwidth of 230 MHz is the small-signal limit; the gain-bandwidth product of 120 MHz sets the closed-loop bandwidth at a given gain (e.g., 12 MHz at a gain of 10).
Supply flexibility and quiescent draw
Quiescent supply current is 14 mA per amplifier — moderate for a high-speed op-amp; budget this into the power rail sizing, especially in multi-channel arrays.
SOT-23-5 footprint and industrial temperature range
The THS4221DBVR comes in a 5-pin SOT-23 package (SC-74A, SOT-753), occupying about 3 mm × 3 mm on the board. The small footprint suits dense mixed-signal layouts where board space is at a premium. Operating temperature range is -40°C to 85°C, covering most industrial, automotive-cabin, and telecom environments.
