詳細說明
The ADS7828E/250 is a single-supply, low-power, 12-bit data acquisition device that features a serial I2C interface and an 8-channel multiplexer. The Analog-to-Digital (A/D) converter features a sample-and-hold amplifier and internal, asynchronous clock. The combination of an I2C serial, 2-wire interface and micropower consumption makes the ADS7828 ideal for applications requiring the A/D converter to be close to the input source in remote locations and for applications requiring isolation. The ADS7828 is available in a TSSOP-16 package.

常見問題解答
What is ADS7828E/250?
The ADS7828E/250 is an 8-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It is designed for applications requiring multiple analog inputs with moderate resolution, such as data acquisition systems, industrial automation, and sensor interfaces.
How Does ADS7828E/250 Work?
The ADS7828E/250 operates by converting analog voltage signals from its 8 input channels into digital data with 12-bit resolution. It utilizes successive approximation register (SAR) architecture to achieve accurate conversions. The ADC features a fast sampling rate and low power consumption, making it suitable for real-time measurement applications.
How Many Pins does ADS7828E/250 have and What are the Functions of the Pinout Configuration?
The ADS7828E/250 is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- VCC, GND: Power supply and ground pins, respectively.
- AGND: Analog ground pin.
- AIN0-AIN7: Analog input channels.
- REF+: Positive reference voltage input.
- REF-: Negative reference voltage input.
- EOC: End of conversion output.
- CLK, DOUT, CS: Serial interface control pins.
What are the Pros and Cons of ADS7828E/250?
