Analog Devices Inc. ADATE318 Single-Chip Solution

Analog Devices Inc. ADATE318 provides a complete, single-chip solution for a wide array of ATE and instrumentation applications. The ADATE318 performs the pin electronics functions of a driver, comparator, and active load (DCL) with a four-quadrant per pin, parametric measurement unit (PPMU). ADATE318's VHH drive capability per chip supports flash memory testing applications. Integrated 16-bit DACs with an on-chip calibration engine deliver all necessary DC levels for operation. The calibration function also corrects gain and offset errors for each functional block. 

Designers can use the ADATE318 from Analog Devices as a dual, single-ended drive/receive channel or as a single differential drive/receive channel. Each channel includes a high-speed window comparator as well as a programmable threshold differential comparator. This single-chip, dual integrated DCL with a four-quadrant PPMU solution operates from -1.5V to +6.5V and delivers data rates up to 600MHz.
