MAX5816
Ultra-Small, Quad-Channel, 12-Bit Buffered Output DAC
with Internal Reference and I2C Interface
Maxim Integrated Products 1
General Description
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 I2C-compatible, 2-wire interface that
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.
