Notes: 1. The parameters are not 100% tested in production.

2. Tested at fosc=40 KHz (RT=3.6 K

Ω, CT=10nF, RD=0 Ω). Approximate oscillator frequency is defined by :

3. DC transconductance (gM) relates to DC open-loop voltage gain (GV) according to the following equation:

GV=gM RL where RL is the resistance from pin 9 to ground. The minimum gM specification is used to calculate

minimum GV when the error amplifier output is loaded.
