Product Summary

The ADC0802LCN is a CMOS 8-Bit, successive-approximation A/D converter which uses a modified potentiometric ladder and is designed to operate with the 8080A control bus via three-state outputs. The ADC0802LCN appears to the processor as memory locations or I/O ports, and hence no interfacing logic is required. The differential analog voltage input has good commonmode- rejection and permits offsetting the analog zero-inputvoltage value. In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution.

Parametrics

ADC0802LCN absolute maximum ratings: (1)Supply voltage: 6.5V; (2)Voltage at any input: -0.3V to (V+ +0.3V).

Features

ADC0802LCN features: (1)80C48 and 80C80/85 bus compatible - no interfacing; (2)Logic required; (3)Conversion time < 100μs; (4)Easy interface to most microprocessors; (5)Will operate in a Stand Alone mode; (6)Differential analog voltage inputs; (7)Works with bandgap voltage references; (8)TTL compatible inputs and outputs; (9)On-chip clock generator; (10)0V to 5V analog voltage input range (single + 5V supply); (11)No zero-adjust required.
