The MAX5816 4-channel, low-power, 12-bit, voltage-

output digital-to-analog converter (DAC) includes output

buffers and an internal reference that is selectable to be

2.048V, 2.500V, or 4.096V. The MAX5816 accepts a wide

supply voltage range of 2.7V to 5.5V with extremely low

power (3mW) consumption to accommodate most low-

voltage applications. A precision external reference input

allows rail-to-rail operation and presents a 100kI (typ)

load to an external reference.

The MAX5816 has an I

operates at clock rates up to 400kHz. The DAC output is

buffered and has a low supply current of less than 250FA

per channel and a low offset error of Q0.5mV (typ). On

power-up, the MAX5816 resets the DAC outputs to zero,

providing additional safety for applications that drive

valves or other transducers which need to be off on pow-

er-up. The internal reference is initially powered down to

allow use of an external reference. The MAX5816 allows

simultaneous output updates using software LOAD com-

mands. Multiple devices can simultaneously be updated

using software load command in combination with the

broadcast ID.

The MAX5816 is available in a 10-pin TDFN package and

is specified over the -40NC to +125NC temperature range.
