Maxim Integrated 

Microprocessor-Compatible,

14-Bit DACs

ELECTRICAL CHARACTERISTICS (continued)

(VDD = +11.4V to +15.75V (Note 1), VREF = 10V, VIOUT = VAGNDS = VSS = 0V, TA = TMIN to TMAX, unless otherwise noted.)

Note 1: Specifications are guaranteed for VDD of +11.4V to +15.75V. At VDD = +5V, device is still functional with degraded specifications.

Note 2: Guaranteed by design, not tested.

Note 3: Resistors have a typical -300ppm/°C tempco.

AC PERFORMANCE CHARACTERISTICS (Note 4)

(VDD = +11.4V to +15.75V, VREF = 10V, VIOUT = VAGND (VAGNDS for MX7535) = VSS = 0V, output amplifier is AD544*,

TA = TMIN to TMAX, unless otherwise noted.)
