How big is the mcp3008 ADC pinout?
8-channel ADC IC with 10-bit resolution and serial SPI interface communication protocol. It has programmable analog inputs which can be configured in either single-ended or pseudo-differential modes. Operate over a range of 2.7V to 5V. The chip employs Successive Approximation (SAR) architecture for ADC conversion.
What kind of current does a mcp3004 have?
The MCP3004/3008 devices operate over a broad voltage range (2.7V – 5.5V). Low-current design permits operation with typical standby currents of only 5 nA and typical active currents of 320 µA. The MCP3004 is offered in 14-pin PDIP, 150 mil SOIC and TSSOP packages, while the MCP3008 is offered in 16- pin PDIP and SOIC packages.
What is the operating voltage of a mcp3008?
MCP3008 is popular because of its user friendly nature and can be made to work with minimum number of components. A sample application circuit for MCP3008 is shown below. In this sample diagram I have set the operating voltage to be 5V, but it can be anywhere between 2.7V to 5V.
What are the pins of the mcp3008 chip?
The pins description of MCP3008 chip is given below: These are the analog inputs for channel 0 to channel 7. These channels can be configured as four single-ended inputs or two pseudo-differential pairs. In pseudo-differential mode, each channel pair are programmed as the IN+ and IN- inputs by sending a serial command string.
What is the mcp3008 analog to digital converter?
MCP3008 is a 10-bit Analogue to Digital converter having eight single-ended input channels. It has a 4-wire serial SPI compatible interface that is used to get digital output for all channels. It has an on-board sample and holds circuitry. It provides both analog and digital ground connections which help in noise reduction.
How is communication initiated with the mcp3008 device?
The communication is initiated with the MCP3008 device is accomplished by bringing the CS line low. On the first clock signal (when CS is low and DIN is high), the first bit received will constitute a start bit. This start bit is followed by the SGL/DIFF bit which determines the mode of conversion either single-ended or differential.
