Dedicated 16-bit digital-to-analog converters (DACs) with on-chip calibration registers provide all the necessary dc levels for operation of the device. The driver features three active modes: high, low, and terminate, as well as a high impedance inhibit state. The inhibit state, in con- junction with the integrated dynamic clamps, facilitates significant attenuation of transmission line reflections when the driver is not actively terminating the line. The open-circuit drive capability is −1.5 V to +4.5 V to accommodate a standard range of ATE and instrumentation applications. The ADATE320 can be used as a dual, single-ended pin electronics channel or as a single differential channel. In addition to per chan- nel high speed window comparators, the ADATE320 provides a programmable threshold differential comparator for differential ATE applications. All dc levels for DCL and PPMU functions are generated by dedicated, on-chip, 16-bit DACs. To facilitate the programming of accurate levels, the ADATE320 includes an integrated calibration function to correct for the gain and offset errors of each functional block. Correction coefficients can be stored on chip, and any values written to the DACs adjust automatically using the appropriate correction factors. The ADATE320 uses a serial programmable interface (SPI) bus to program all functional blocks, DACs, and on-chip calibration constants. It also has an on-chip temperature sensor and overvolt- age/undervoltage fault clamps that monitor and report the device temperature and any output pin or transient PPMU voltage faults that may occur during operation. The ADATE320 is available in two options. The standard option has high speed comparator outputs with 250 mV output swing. The ADATE320-1 has 400 mV output swing.
