Speedy settling for dual and octal DACs
A new family of dual and octal DACs with 8, 10 and 12bit resolutions use a fast output buffer that guarantees less than 3us full-scale settling time to 0.5LSB
They provide excellent static accuracy at all resolutions: INL and DNL better than 1LSB; offset error guaranteed less than 5mV; and gain error less than 4LSB. Two settling time modes are available to trade-off settling time for power consumption. The fast mode reduces settling time to a maximum of 3us.

The MAX2120 is ideal for DVB-S and free-to-air applications in which low cost and ease of use are key requirements
The slow mode reduces maximum supply current to 3.2mA for the MAX5590-MAX5595 and 800uA for the MAX5290-MAX5295.
Excellent DC accuracy and low power make these DACs ideal for industrial applications including process control, automatic test equipment (ATE) and motion control.
The MAX5590-MAX5595 operate from single 2.7 to 5.25V supplies and the MAX5290-MAX5295 operate from single 2.7 to 3.6V supplies.
Each device accepts clock speeds up to 20MHz using a three-wire SPI/QSPI/Microwire-compatible serial interface.
Two user-programmable digital I/O pins increase flexibility by adding advanced functions.
Some of these functions include readback, daisychain capability, load DAC for asynchronously updating channels, and hardware shutdown.
Each DAC is buffered with a fast-settling amplifier preconfigured in either force-sense or unity-gain.
The MAX5290-MAX5295 are available in 4 x 4mm 16-pin QFN or 14- and 16-pin TSSOP packages.
The MAX5590-MAX5595 are available in 24-pin and 28-pin TSSOPs.
Prices start at $3.08 (1000-up, FOB USA).
