Overview
The ADS8326IBDGKR is a 16-bit, high-speed, microPower sampling analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed to operate within a supply voltage range of 2.7V to 5.5V, making it highly versatile for various applications. The ADS8326 is known for its low power consumption, even at full data rates, and its ability to spend most of its time in power-down mode at lower data rates. This ADC features a synchronous serial (SPI/SSI-compatible) interface and a differential input, with the reference voltage adjustable within the range of 0.1V to VDD.
The device is available in MSOP-8 and SON-8 packages, making it ideal for portable and battery-operated systems, remote data acquisition modules, simultaneous multichannel systems, and isolated data acquisition.
