SBOS483H – JULY 2009 – REVISED NOVEMBER 2013
ELECTRICAL CHARACTERISTICS: V_S = 1.8 V to 5.5 V
Boldface limits apply over the specified temperature range, T_A = –55°C to 210°C. At T_A = 25°C, R_L = 10 kΩ connected to
V_S/2, V_CM = V_S/2, and V_OUT = V_S/2 (unless otherwise noted).

(1) Minimum and maximum parameters are characterized for operation at T_A = 175°C, but may not be production tested at that
temperature. Production test limits with statistical guardbands are used to ensure high temperature performance.
(2) Minimum and maximum parameters are characterized for operation at T_A = 210°C, but may not be production tested at that
temperature. Production test limits with statistical guardbands are used to ensure high temperature performance.
(3) 300-hour life test at 150°C demonstrated randomly distributed variation of approximately 1 μV.
(4) The OPA2333-HT is not intended to be used as a comparator due to its limited differential input range capability.
