Product Summary

The AD578JN is a high speed 12-bit successive approximation analog-to-digital converter that includes internal clock, reference, and comparator. Its hybrid design utilizes MSI digital and linear IC in conjunction with a 12-bit monolithic, monotonic DAC to provide superior performance and versatility with IC size, price, and reliability. Important performance characteristics of the AD578JN include ±1/2 LSB linearity error maximum at +25℃, maximum gain tempco of ±30ppm/℃ and maximum conversion time of 3μs at a typical power dissipation of 555mW.
