SPECIFICATIONS
ELECTRICAL
At T
A = +25°C: VS1 = VS2 = ±15V: and RL = 2k, unless otherwise noted.
*Specifications same as ISO120BG, ISO121BG.
NOTE: (1) Input voltage range =
±10V for V
S1, VS2 = ±4.5VDC to ±18VDC. (2) Ripple frequency is at carrier frequency. (3) Overload recovery is approximately three times
the settling time for other values of C
2. (4) The SG-grade is specified –55°C to +125°C; performance of the SG in the –25°C to +85°C temperature range is the same
as the BG-grade.
