ADC0809 8-Bit A/D Converter with 8-Channel Multiplexer IC DIP-28 Package

The ADC0809 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.The device eliminates the need for external zero and full-scale adjustments. Easy interfacing to microprocessors is provided by the latched and decoded multiplexer address inputs and latched TTL TRI-STATE outputs.The design of the ADC0809 has been optimized by incorporating the most desirable aspects of several A/D conversion techniques. The ADC0809 offers high speed, high accuracy, minimal temperature dependence, excellent long-term accuracy and repeat-ability, and consumes minimal power. These features make this device ideally suited to applications from process and machine control to consumer and automotive applications.Features:–Easy Interface to All MicroprocessorsOperates Ratio-metrically or with 5 VDC or Analog Span Adjusted Voltage ReferenceNo Zero or Full-Scale Adjust Required8-Channel Multiplexer with Address Logic0V to VCC Input RangeOutputs meet TTL Voltage Level SpecificationsADC0809 Equivalent to MM74C949-1Specifications:-ParametersSpecificationPart numberADC0809-NResolution (Bits)8Sample rate (Max) (kSPS)10Number of input channels8InterfaceParallelOperating temperature range ( C )-40 to 85Package GroupPLCC | 28Power consumption (Typ) (mW)15Package size: mm2:W x L (PKG)28PLCC: 155 mm2: 12.45 x 12.45 (PLCC | 28)ArchitectureSARInput typeSingle-EndedMulti-channel configurationMultiplexedInput range (Max) (V)6Input range (Min) (V)0Analog voltage AVDD (Min) (V)4.5Analog voltage AVDD (Max) (V)6Digital supply (Min) (V)4.5Digital supply (Max) (V)6INL (Max) ( /-LSB)1.25RatingSee Data Sheetadc0809-ic-datasheet* product image for illustration purposes only. actual product may vary.
