The ADI Chinese version datasheet is a translation of the English version datasheet, introducing the features and characteristics of the AD7298, an 8-channel, 1 MSPS, 12-bit SAR ADC with built-in temperature sensor.
The AD7298 is a 12-bit, high-speed, low-power, 8-channel successive approximation ADC with an integrated temperature sensor. It operates from a single 3.3V supply with a throughput rate of up to 1 MSPS. The device features a low-noise, wide-bandwidth sample-and-hold amplifier capable of handling input frequencies up to 30 MHz. This manual is written in Chinese.
