Product Summary

The ADC0804LCN is a CMOS 8-bit successive approximation A/D converter that uses a differential potentiometric ladder, similar to the 256R products. This converter is designed to allow operation with the NSC800 and INS8080A derivative control bus with TRI-STATE output latches directly driving the data bus. This A/Ds of ADC0804LCN appear like memory locations or I/O ports to the microprocessor and no interfacing logic is needed.

Parametrics

ADC0804LCN absolute maximum ratings: (1)Supply Voltage (VCC): 6.5V; (2)Logic Control Inputs: -0.3V to +18V; (3)At Other Input and Outputs: -0.3V to (VCC+0.3V); (4)Dual-In-Line Package (plastic): 260℃; (5)Dual-In-Line Package (ceramic): 300℃; (6)Vapor Phase (60 seconds): 215℃.

Features

ADC0804LCN features: (1)Compatible with 8080 μP derivatives, no interfacing logic needed access time 135ns; (2)Easy interface to all microprocessors, or operates stand alone; (3)Differential analog voltage inputs; (4)Logic inputs and outputs meet both MOS and TTL voltage level specifications; (5)Works with 2.5V (LM336) voltage reference; (6)On-chip clock generator; (7)0V to 5V analog input voltage range with single 5V supply; (8)No zero adjust required; (9)0.3 standard width 20-pin DIP package; (10)20-pin molded chip carrier or small outline package; (11)Operates ratiometrically or with 5 VDC, 2.5 VDC,or analog span adjusted voltage reference.
