HIGH-SPEED DIFFERENTIAL I/O FAMILY The THS412x is one in a family of fully differential-input, differential-output devices NUMBER OF DEVICE POWERDOWN CHANNELS fabricated using Texas Instruments' state-of-the-art submicron CMOS process. THS4120(1) 1 Yes THS4121 1 – The THS412x consists of a true, fully differential signal path from input to output. This results in excellent common-mode noise rejection and (1) For proper functiionality, an external 10-k Ω pullup resistor is improved total harmonic distortion. required between the PD pin and the positive supply.
