ELECTRICAL CHARACTERISTICS—MAX7490 (continued)

(VDD = EXTCLK = +5V, fCLK = 625kHz, TA = TMIN to TMAX, 10kΩ || 50pF load to VDD/2 at LP_, BP_, and N_/HP_, SHDN = VDD, 0.1µF

from COM to GND, 50% duty-cycle clock input, COM = VDD/2. Typical values are at TA = +25°C, unless otherwise noted.) (Note 1)
