Overview
The AD7658BSTZ-1, produced by Analog Devices Inc., is a high-performance analog-to-digital converter (ADC) that integrates six 12-bit successive approximation ADCs in a single package. This device is designed using the iCMOS® process, which combines high voltage silicon with submicron CMOS and complementary bipolar technologies. This technology enables the development of high-performance analog ICs capable of operating at high voltages while reducing power consumption and package size. The AD7658BSTZ-1 is ideal for applications requiring multiple high-speed, low-power ADCs with true bipolar input capabilities.
