MAX478/MAX479
17µA Max, Dual/Quad, Single-Supply,
Precision Op Amps
8 _______________________________________________________________________________________
ELECTRICAL CHARACTERISTICS: ±15V
(V
S
= ±15V, T
A
= -40°C to +85°C, unless otherwise noted.)
Note 1: Guaranteed by design.
Note 2: Power-supply rejection ratio is measured at the minimum supply voltage. The op amps actually work at 1.7V supply, but
with additional input offset-voltage skew.
