AD1674AD

AD1674AD is a complete, multipurpose, 12bit analogue-to-digital converter, consisting of a user-transparent onboard sample-and-hold amplifier (SHA), 10V reference, clock and three-state output buffers for microprocessor interface. It is pin-compatible with the industry standard AD574A and AD674A but includes a sampling function while delivering a faster conversion rate. The on-chip SHA has a wide input bandwidth supporting 12bit accuracy over the full Nyquist bandwidth of the converter. It is fully specified for ac parameters (such as S/(N+D) ratio, THD, and IMD) and DC parameters (offset, full-scale error, etc.). With both AC and DC specifications, the AD1674 is ideal for use in signal processing and traditional DC measurement applications. The AD1674 design is implemented using Analog Devices’ BiMOS II process allowing high-performance bipolar analogue circuitry to be combined on the same die with digital CMOS logic.
