Overview
The ADS8325IBDGKT is a 16-bit, sampling, Analog-to-Digital (A/D) converter produced by Texas Instruments. It operates within a supply voltage range of 2.7V to 5.5V, making it highly versatile for various applications. This device is known for its low power consumption, even at full 100kHz data rates, and its ability to spend most of its time in power-down mode at lower data rates, resulting in average power dissipation of less than 1mW at 10kHz. The ADS8325IBDGKT offers excellent linearity and very low noise and distortion, along with a synchronous serial (SPI/SSI compatible) interface and a differential input. The reference voltage can be set to any level within the range of 2.5V to VDD, enhancing its flexibility in different systems.
