Notes:
1. 20 MHz bandwidth. An external 2.2mf ceramic
capacitor is recommended to be placed from +V out
to -V out.
2. Consult Technical Reference Notes for Recommended
Input/Output Filtering
3. All specifications are typical at nominal line, full load,
and 25 C unless otherwise noted.
4. All specifications subject to change without notice.
