ADC0808 8 bit A/D Convertor with 8-Channel Multiplexer

introduction :

The ADC0808 data acquisition component is a monolithic CMOS device with an 8-bit analog-to-digital converter, 8-channel multiplexer and microprocessor compatible control logic.

The 8-bit A/D converter uses successive approximation as the conversion technique.

The converter features a high impedance chopper stabilized comparator, a 256R voltage divider with analog switch tree and a successive approximation register.

The 8-channel multiplexer can directly access any of 8-single-ended analog signals.

Features :

• Easy interface to all microprocessors.
• Operates ratiometrically or with 5 VDC or analog span adjusted voltage reference.
• No zero or full-scale adjust required.
• 8-channel multiplexer with address logic.
• 0V to VCC input range.
• Outputs meet TTL voltage level specifications.
• Package Type : DIP24 pin.
