Where FOUTX = Nominall rated frequency (4Hz or 1160Hz)  
FOSC  
= Oscillator frequency (2MHz ...... 4MHz)  
= Input currents for current input (16µA at rated)  
= Input current for voltage input (14µA at rated)  
= Reference current (typically 50µA)

XTAL is a colour burst TV crystal (f = 3.5795MHz) for the oscillator. The oscillator  
frequency is divided down to 1.7897MHz on-chip to supply the digital circuitry and the  
A/D converters.
