The AD7656A-1 is a reduced decoupling pin- and software-compatibleversion of AD7656A. The AD7656A-1 contains six 16-bit, fast, low power successive approximation ADCs in a package designed on the iCMOS® process (industrial CMOS). iCMOS is a process combining high voltage silicon with submicron CMOS and complementary bipolar technologies. It enables the development of a wide range of high performance analog ICs,capable of 33 V operation in a footprint that no previousgeneration of high voltage devices could achieve. Unlike analogICs using conventional CMOS processes, iCMOS componentscan accept bipolar input signals while providing increasedperformance, which dramatically reduces power consumptionand package size.The AD7656A-1 features throughput rates of to 250 kSPS. Itcontains wide bandwidth (4.5 MHz), track-and-hold amplifiersthat can handle input frequencies up to 4.5 MHz.The conversion process and data acquisition are controlledusing the CONVST x signals and an internal oscillator. ThreeCONVST x pins (CONVST A, CONVST B, and CONVST C)allow independent, simultaneous sampling of the three ADCpairs. The AD7656A-1 has a high speed parallel and serialinterface, allowing the device to interface with microprocessorsor digital signal processors (DSPs). In serial interface mode, theAD7656A-1 has a daisy-chain feature that allows multipleADCs to connect to a single serial interface. The AD7656A-1can accommodate true bipolar input signals in the ±4 × VREFrange and the ±2 × VREF range. The AD7656A-1 also contains an on-chip 2.5 V reference.Multifunction pin names may be referenced by their relevantfunction only.Please visit next generation product AD7606.PRODUCT HIGHLIGHTS Six 16-bit, 250 kSPS ADCs on board. Six true bipolar, high impedance analog inputs. High speed parallel and serial interfaces. Reduced decoupling requirements and reduced bill of materials cost compared with the AD7656A.
