Negative Power Supply. Nominally –5.0 V.
Ground
Internal Reference Output (–2.5 V typical); Bypass with 0.1 µF to Ground
Reference Input for ADC (–2.5 V typical)
Internal Amplifier Compensation, 0.1 µF to VEE
Reference Bypass Node, 0.1 µF to VEE
Analog Input – Complement
Analog Input – True
Encode Clock for ADC (ADC Samples on Rising Edge of ENCODE).
Encode Clock Complement (ADC Samples on Falling Edge of ENCODE).
Digital Outputs of ADC. D9 is the MSB. Data is two’s complement.
Out-of-Range Output. Goes HIGH when the converted sample is more
positive than 1FFh or more negative than 200h (Two’s Complement Coding).
