8-Bit, 40MHz, Current/Voltage-Output DACs
General Description
The MAX5187 is an 8-bit, current-output digital-to-ana-
log converter (DAC) designed for superior performance
in signal reconstruction or arbitrary waveform genera-
tion applications requiring analog signal reconstruction
with low distortion and low-power operation. The volt-
age-output MAX5190 provides equal specifications,
with on-chip precision resistors for voltage output oper-
ation. Both devices are designed for a 10pVs glitch
operation to minimize unwanted spurious signal com-
ponents at the output. An on-board +1.2V bandgap cir-
cuit provides a well-regulated, low-noise reference that
can be disabled for external reference operation.
The MAX5187/MAX5190 are designed to provide a high
level of signal integrity for the least amount of power
dissipation. They operate from a single supply of +2.7V
to +3.3V. Additionally, these DACs have three modes of
operation: normal, low-power standby, and full shut-
down, which provides the lowest possible power dissi-
pation with a 1µA (max) shutdown current. A fast
wake-up time (0.5µs) from standby mode to full DAC
operation allows for power conservation by activating
the DAC only when required.
The MAX5187/MAX5190 are packaged in a 24-pin
QSOP and are specified for the extended (-40°C to
+85°C) temperature range. For higher resolution, 10-bit
versions, see the MAX5181/MAX5184 data sheet.
