* These parameters, although guaranteed over the recommended operating conditions, are not 100 % tested in production.
• Tested at fosc = 40 KHz (RT = 3.6 KΩ, CT = 10nF, RD = 0 Ω). Approximate oscillator frequency is defined by :
f=
1
CT (0.7 RT + 3 RD)
.DC transconductance (gM) relates to DC open-loop voltage gain (Gv) according to the following equation : Gv = gM RL whereRL 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.
