(1)

Limits are guaranteed by testing or correlation.

(2)

A military RETS electrical test specification is available on request. At the time of printing, the LPC660AMJ/883 RETS specification

complied fully with the boldface limits in this column. The LPC660AMJ/883 may also be procured to a Standard Military Drawing

specification.

V+ = 15V. Connected as Voltage Follower with 10V step input. Number specified is the slower of the positive and negative slew rates.

(4)

Input referred. V+ = 15V and RL = 100 kΩ connected to V

+/2. Each amp excited in turn with 1 kHz to produce V

O = 13 VPP.
