MAXIM MAX5290, MAX5295 User Manual

General Description
The MAX5290–MAX5295 dual, 12-/10-/8-bit, voltage­output digital-to-analog converters (DACs) offer buffered outputs and a 3µs maximum settling time at the 12-bit level. The DACs operate from a 2.7V to 5.25V analog supply and a separate 1.8V to 3.6V digital sup­ply. The 20MHz 3-wire serial interface is compatible with SPI™, QSPI™, MICROWIRE™, and digital signal processor (DSP) protocol applications. Multiple devices can share a common serial interface in direct access or daisy-chained configuration. The MAX5290–MAX5295 provide two multifunctional, user-programmable, digital I/O ports. The externally selectable power-up states of the DAC outputs are either zero scale, midscale, or full scale. Software-selectable FAST and SLOW settling modes decrease settling time in FAST mode, or reduce supply current in SLOW mode.
The MAX5290/MAX5291 are 12-bit DACs, the MAX5292/ MAX5293 are 10-bit DACs, and the MAX5294/MAX5295 are 8-bit DACs. The MAX5290/ MAX5292/MAX5294 pro­vide unity-gain-configured output buffers, while the MAX5291/MAX5293/MAX5295 provide force-sense-con­figured output buffers. The MAX5290– MAX5295 are specified over the extended -40°C to +85°C temperature range, and are available in space-saving 4mm x 4mm, 16-pin thin QFN and 6.5mm x 5mm, 14-pin and 16-pin TSSOP packages.

Note 1: For the force-sense versions, FB_ is connected to its respective OUT_. V
OUT
(max) = V
REF
/ 2, unless otherwise noted.
Note 2: Linearity guaranteed from decimal code 40 to 4095 for the MAX5290A/MAX5291A (12-bit, A-grade), code 82 to 4095 for the
MAX5290B/MAX5291B (12-bit, B-grade), code 21 to 1023 for the MAX5292/MAX5293 (10-bit), and code 5 to 255 for the MAX5294/MAX5295 (8-bit).
Note 3: DAC-to-DAC crosstalk is measured as follows: outputs of DACA and DACB are set to full scale and the output of DACB is
measured. While keeping DACB unchanged, the output of DACA is transitioned to zero scale and the ∆V
OUT
of DACB is
measured. The procedure is repeated with DACA and DACB interchanged. DAC-to-DAC crosstalk is the maximum ∆V
OUT
measured.
Note 4: Represents the functional range. The linearity is guaranteed at V
REF
= 2.5V. See the Typical Operating Characteristics sec-
tion for linearity at other voltages.
Note 5: Guaranteed by design. Note 6: The reference -3dB bandwidth is measured with a 0.1V
P-P
sine wave on V
REF
and with the input code at full scale.
Note 7: In some daisy-chain modes, data is required to be clocked in on one clock edge and the shifted data clocked out on the fol-
lowing edge. In the case of a 1/2 clock-period delay, it is necessary to increase the minimum high/low clock times to 25ns (2.7V) or 50ns (1.8V).
Note 8: The falling edge of DSP starts a DSP-type bus cycle, provided that CS is also active low to select the device. DSP active low
and CS active low must overlap by a minimum of 10ns (2.7V) or 20ns (1.8V). CS can be permanently low in this mode of
