Overview
The AD7658YSTZ is a high-performance analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is part of the AD7656/AD7657/AD7658 family, which features six 16-/14-/12-bit successive approximation ADCs in a single package. The AD7658YSTZ is designed using the iCMOS process, combining high voltage silicon with submicron CMOS and complementary bipolar technologies. This technology enables the development of high-performance analog ICs capable of 33 V operation in a compact footprint, significantly reducing power consumption and package size. The device is optimized for low power consumption and high noise performance, making it suitable for a variety of applications requiring precise and efficient data conversion.
