MAX5188/MAX5191
Dual, 8-Bit, 40MHz, Current/Voltage,
Alternate-Phase Output DACs
______________________________________________________________________________________

Timing Information
Both internal DAC cells write to their outputs in alternate
phase (Figure 4). The input latch of the first DAC
(DAC1) is loaded after the clock signal transitions high.
When the clock signal transitions low, the input latch of
the second DAC (DAC2) is loaded. The contents of the
first input latch are shifted into the DAC1 register on the
rising edge of the clock; the contents of the second
input latch are shifted into the input register of DAC2 on
the falling edge of the clock. Both outputs are updated
on alternate phases of the clock.
Outputs
The MAX5188 outputs are designed to supply 1mA full-
scale output currents into 400
loads in parallel with a
capacitive load of 5pF. The MAX5191 features integrat-
ed 400
resistors that restore the array currents into
proportional, differential voltages of 400mV. These dif-
ferential output voltages can then be used to drive a
balun transformer or a low-distortion, high-speed oper-
ational amplifier to convert the differential voltage into a
single-ended voltage.

Performance Definitions
Integral Nonlinearity
Integral nonlinearity (INL) (Figure 5a) is the deviation of
the values on an actual transfer function from either a
best-straight-line fit (closest approximation to the actual
transfer curve) or a line drawn between the endpoints
