ADC0804LCN/NOPB Datasheet PDF - TI

The ADC0804LCN/NOPB is a CMOS 8-bit successive approximation Analogue-to-digital Converter that uses a differential potentiometric ladder. 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 ADC appears like memory locations or I/O ports to the microprocessor and no interfacing logic is needed. Differential analogue voltage inputs allow increasing the common-mode rejection and offsetting the analogue zero input voltage value. In addition, the voltage reference input can be adjusted to allow encoding any smaller analogue voltage span to the full 8 bits of resolution.

● Easy interface to all microprocessors or operates as a stand-alone device

● Differential analogue voltage inputs

● Logic inputs and outputs meet both MOS and TTL voltage-level specifications

● On-chip clock generator

● No zero adjust required

● 100µs Conversion time

● Green product and no Sb/Br

●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
