In addition, the family offers excellent ac performance with 230-MHz bandwidth, 975-V/ µs slew rate and harmonic distortion (THD) at –90 dBc at 5 MHz. 1 kΩ 650 Ω 1.3 kΩ − + 5 V 2.5 V IN+ THS4222 650 Ω 1.3 kΩ − + 2.5 V IN− Vout− Vout+ 0 400 600 1200 1400 1600 1800 012 4 5 VO − Differential Output Voltage Step − V SLEW RATE vs DIFFERENTIAL OUTPUT VOLTAGE STEP 200 1000 800 67 89 10 3 Rise Fall DIFFERENTIAL DRIVE CIRCUIT 0.1 µF 10 µF PRODUCTION DATA information is current as of publication date.
