ADS7830IPWT 8-Bit, 8-Channel Sampling ANALOG-TO-DIGITAL CONVERTER with I 2C™ Interface

ADS7830IPWT 8-Bit, 8-Channel Sampling ANALOG-TO-DIGITAL CONVERTER with I 2C ™ Interface

DESCRIPTION 
The ADS7830 is a single-supply, low-power, 8-bit data acquisition device that features a serial PC 
interface and an 8-channel multiplexer. The Analog-to-Digital (ND) converter features a sample-and-hold amplifier and internal, asynchronous dock. The combination of an I2C serial, 2-wire interface and micropower consumption makes the ADS7830 ideal for applications requiring the ND converter to be dose to the input source in remote locations and for applications requiring isolation. The ADS7830 is available in a TSSOP-16 package.

Acoustimeter RF Meter Model AM-10

Acoustimeter RF Meter The AM-10 model is a microwave level radiation (microwave) measuring device designed to measure microphones at a frequency range between 200 MHz to 8 GHz accurately. What is unique about this tool is that the microwave measurement results are displayed on two different media, LED bar and LCD. The LED bar will move quickly from one parameter to another according to the level of wave radiation read by the sensor while the LCD will display real-time wave reading results to the monitor in letter and number format. In addition, the device also has a speaker and audio jack for headphones and a microphone that can allow users to identify the wave radiation read by the sensor.
