MAX5101AEUE+T

P1-P3P4-P6P7-P8
General Description
The MAX5101 parallel-input, voltage-output, triple 8-bit
digital-to-analog converter (DAC) operates from a sin-
gle +2.7V to +5.5V supply and comes in a space-sav-
ing 16-pin TSSOP package. Internal precision buffers
swing rail-to-rail. For all three DACs, the internal refer-
ence voltage is tied to V
DD
.
The MAX5101 has separate input latches for each of its
three DACs. Data is transferred to the input latches
from a common 8-bit input port. The DACs are individu-
ally selected through address inputs A0 and A1 and
are updated by bringing WR low.
The MAX5101 features a 1µA software shutdown mode,
as well as a power-on reset mode that resets all regis-
ters to code 00 hex on power-up.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: Reduced digital code range (code 00 hex to code F0 hex) due to swing limitations when the output amplifier is loaded.
Note 2: Gain error is: [100 (V

F0,ideal
) / V
DD
]. Where V
F0,meas
is the DAC output voltage with input code F0 hex, and
V

Note 3: Output settling time is measured from the 50% point of the falling edge of WR to ±1/2LSB of V

’s final value.
Note 4: Channel-to-Channel Isolation is defined as the glitch energy at a DAC output in response to a full-scale step change on any
other DAC output. The measured channel has a fixed code of 80 hex.
