National Semiconductor ADC1021
The ADC100l and ADC1021 are CMOS, 10-bit successive • Easily interlaced to 6800 ,..p derivatives with minimal approximation AID converters. The 20-pin ADC100l is pin external logic compatible with the ADC0801 8-bit AID family. The 10-bit data word is read in two 8-bit bytes, formatted left justified and high byte first.| Part No. | ADC1021 |

GENERAL DESCRIPTION
The six least significant bits of the second byte are set to zero, as is proper for a 16-bit word. The 24-pin ADC1021 outputs 10 bits parallel and is intended for interlace to a 16-bit data bus. Differential inputs provide low frequency input common● Differential analog voltage inputs
● Logic inputs and outputs meet both MOS and TTL volt- age level specifications
● Works with 2.5V (LM336) voltage reference
● On-chip clock generator
● OV to 5V analog input voltage range with single 5V sup- ply mode rejection and allow offsetting the analog range of the converter. In addition, the reference input can be adjusted enabling the conversion of reduced analog ranges with 10bit resolution.
● Operates ratiometrically or with 5 Voc, 2.5 Voc, or analog span adjusted voltage reference
● 0.3" standard width 20-pin DIP package or 24 pins with 1O-bit parallel output
FEATURES
● ADC100l is pin compatible with ADC0801 series 8-bit AID converters● Compatible with NSC800 and 8080 ,..p...
