The THS412x is a high-performance fully differential I/O amplifier with 100 MHz, -3 dB bandwidth, 50 V/µs slew rate, 75 dB total harmonic distortion (VO = 2 VPP) and 5.4 nV/√Hz input-referred noise (10 kHz). The amplifier is fabricated using Texas Instruments' state-of-the-art submicron CMOS process and is a 1-channel differential input/differential output device.
The THS4120 and THS4121 are members of Texas Instruments' THS412x family of fully differential input‑output amplifiers fabricated in a sub‑micron CMOS process. They provide true differential signal paths, excellent common‑mode rejection, and low total harmonic distortion, making them suitable for single‑ended‑to‑differential conversion, ADC drivers, and level shifting.
The devices operate from a single 3.3 V supply, support output currents up to 110 mA (sink) and 25 mA (source), and are offered in Small‑Outline (D), DGN, and DGK packages. Detailed electrical characteristics, recommended operating conditions, and mechanical dimensions are provided for design integration.
