The ADS7822E/250 is an integrated circuit (IC) component that provides 12-bit analog-to-digital conversion functionality. Produced by Texas Instruments, this IC is widely used in a range of applications to convert analog signals into digital data.
One notable feature of the ADS7822E/250 is its ability to convert two analog input channels simultaneously. This dual-channel conversion capability makes it suitable for applications where multiple analog signals need to be converted and processed simultaneously.
The IC operates with a supply voltage range of 2.7V to 5.25V, allowing compatibility with a variety of systems. Its low power consumption and small form factor make it suitable for battery-powered devices and space-constrained applications.
Another significant feature is the selectable input range. The ADS7822E/250 offers programmable input ranges, allowing users to adapt the IC to the specific requirements of their application. The available input ranges are 0V to VREF, 0V to 2 × VREF/2, or 0V to 2 × VREF. This flexibility enhances the IC's versatility.
The device includes an integrated oscillator, eliminating the need for external clock sources. This oscillator can be driven by an external crystal or a resistor-capacitor network, further simplifying circuit design.
Additionally, the ADS7822E/250 offers both I2C and SMBus compatible digital interfaces, providing easy communication with microcontrollers and other digital devices
