CT = 0.01 μF, RT = 12 kΩ (see Figure 8-1)
|PARAMETER||TEST CONDITIONS(1)||TL494C, TL494I||UNIT|
|Standard deviation of frequency(3)||All values of VCC, CT, RT, and TA constant||100||Hz/kHz|
|Frequency change with voltage||VCC = 7 V to 40 V, TA = 25°C||1||Hz/kHz|
|Frequency change with temperature(4)||ΔTA = MIN to MAX||10||Hz/kHz|
(1) For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
(2) All typical values, except for parameter changes with temperature, are at TA = 25°C.
Standard deviation is a measure of the statistical distribution about the mean as derived from the formula:
(4) Temperature coefficient of timing capacitor and timing resistor are not taken into account.
