AD1674 Datasheet PDF

●Product Details

●The AD1674 is a complete, multipurpose, 12-bit analog-to-digital converter, consisting of a user-transparent on-board sample-and-hold amplifier (SHA), 10 volt reference, clock and three-state output buffers for microprocessor interface.

●The AD1674 is pin compatible with the industry standard AD574A and AD674A, but includes a sampling fuction while delivering a faster conversion rate. The on-chip SHA has a wide input bandwidth supporting 12-bit accuracy over the full Nyquist bandwidth of the converter.

●The AD1674 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 analog circuitry to be combined on the same die with digital CMOS logic.

●Five different temperature grades are available. The AD1674J and K grades are specified for operation over the 0°C to +70°C temperature range. The A and B grades are specified from -40°C to +85°C; the AD1674T grade is specified from -55°C to +125°C. The J and K grades are available in both 28-lead plastic DIP and SOIC. The A and B grade devices are available in 28-lead hermetically sealed ceramic DIP and 28-lead SOIC. The T grade is available in 28-lead hermetically sealed ceramic DIP.
