Package

The AD7478ARTZ is packaged in a 16-lead TSSOP (Thin Shrink Small Outline Package).

Pinout

The AD7478ARTZ is a 12-bit analog-to-digital converter (ADC) that typically comes in a 16-lead TSSOP package. It features a total of 16 pins.
Key functions of the pins include:
1. Analog Input (AIN0): The primary input for the analog signal to be converted.
2. Digital Output (D0-D11): The digital output pins that provide the converted 12-bit data.
3. Chip Select (CS): Used to enable or disable the chip.
4. Clock Input (SCLK): The serial clock input for data transfer.
5. Data Ready (DRDY): Indicates when the conversion is complete and data is available.
6. Reference Voltage (VREF): Sets the reference voltage for the ADC.
7. Power Supply (VDD, VSS): Power supply pins for the ADC operation.
8. Reset (RESET): Resets the internal registers of the ADC.
This ADC is designed for low-power applications and has features like a serial interface for easy integration.
