LTC6994-1/LTC6994-2

ELECTRICAL CHARACTERISTICS ^Thel denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at T_A= 25°C. Test conditions are V⁺= 2.25V to 5.5V, IN = 0V, DIVCODE = 0 to 15

(N_DIV= 1 to 2²¹), R_SET= 50k to 800k, R_LOAD= 5k, C_LOAD= 5pF unless otherwise noted.
