MAX7528

The MAX7528 contains two 8-bit multiplying digital-to-analog converters (DACs). Seperate on-chip latches hold the input data for each DAC to allow easy interface to microprocessors. The data load operation is similar to a static RAM write cycle. Each DAC has a seperate reference input and internal feedback resistor. The typical applications include programmable attenuators, digitally controlled filters, X-Y graphics, motion control system, digital-to-sybchro conversion and disk drives.

There are some features as follows: (1)data latches for both DACs; (2)+5 to +15 V single supply operation; (3)±1/2 LSB linearity; (4)microprocessor compatible; (5)four-quadrant multiplication; (6)DACs matched to 1%.

The following is about the absolute maximum ratings: (1)VDD to AGND: 0 to +17 V; (2)VDD to DGND: 0 to +17 V; (3)AGND to DGND: VDD; (4)DGND to AGND: VDD; (5)digital input voltage to DGND: -0.3 to VDD V; (6)pin 2, pin 20 to AGND: -0.3 to VDD V; (7)VREFA, VREFB to AGND: ±25 V; (8)VREBA, VREBB to AGND: ±25 V; (9)storage temperature range: -65 to +160; (10)power dissipation (any package) to +75: 450 mW; (11)lead temperature (soldering, 10 sec): 300.
