AD7656-1/AD7657-1/AD7658-1 are pin- and software-compatible versions of the AD7656/AD7657/AD7658 with reduced decoupling requirements, each integrating 6 channels of 16/14/12-bit, fast, low-power successive approximation ADCs in a single package, designed using iCMOS (industrial CMOS) process technology.
iCMOS is a process that combines high-voltage silicon with submicron CMOS and complementary bipolar technologies. This process enables the development of high-performance analog ICs operating at up to 33V, achieving a size-to-performance ratio previously unattainable with conventional high-voltage devices. Unlike analog ICs built on traditional CMOS processes, iCMOS devices accept bipolar input signals while delivering improved performance, significantly reduced power consumption, and smaller package sizes.
All three devices offer throughput rates up to 250kSPS and integrate low-noise, wide-bandwidth track-and-hold amplifiers capable of handling input frequencies up to 4.5MHz.
The conversion process and data acquisition are controlled via the CONVST signal and an internal oscillator. Three CONVST pins (CONVSTA, CONVSTB, and CONVSTC) allow three pairs of ADCs to perform simultaneous sampling independently.
AD7656-1/AD7657-1/AD7658-1 feature a high-speed parallel interface and a high-speed serial interface, facilitating connection between the devices and a microprocessor or DSP. When serial interface mode is selected, each device allows multiple ADCs to be connected in a daisy-chain configuration to a single serial interface.
All three devices support true bipolar input signals in both the ±4×VREF and ±2×VREF ranges, and also integrate an on-chip 2.5V reference.
