DAC8221

The DAC8221 combines two identical 12 bit, multiplying, digital-to-analog converters into a single CMOS chip. The features of DAC8221 can be summarized as (1)two matched 12-bit DACs on one chip; (2)packaged in a narrow 0.3*24 pin DIP; (3)direct parallel load of all 12 bits for high data throughout; (4)on-chip latches for both DACs; (5)12 bit endpont linearity over temperature; (6)+5V to +15V single supply operation; (7)DACs matched to 0.2% typically; (8)four quadrant multiplication; (9)inproved ESD resistance; (10)available in die form.

The absolute maximum ratings of the DAC8221 are: (1)VDD to AGND: 0V,+17V; (2)VDD to DGND: 0V,+17V; (3)AGND to DGND: -0.3V, VDD+0.3V; (4)digital input voltage to DGND: -0.3V, VDD+0.3V; (5)IOUT A, IOUT B to AGND: ±25V; (6)IREF A, IREF B to AGND: ±25V; (7)operating temperature range AW version: -55 to +125, EW, FW,FP versions: -40 to +85, GP, HP,HS versions: -0 to +70; (8)junction temperature: 150; (9)storage temperature: -65 to +150; (10)lead temperature: +300.

The following is about the electrical characteristics of DAC8221: (1)supply current: 1mA typical and 2mA max at all digital input VINL or VINH; (2)DC power supply rejection ratio: 0.002%/% at VDD=±5%; (3)propagation delay: 350ns at TA=+25; (4)current setting time: 0.45s typical and 1s max at TA=+25; (5)output capacitance: 30pF typical and 90pF max.
