MAX5823/MAX5824/MAX5825

Ultra-Small, Octal Channel, 8-/10-/12-Bit Buffered

Output DACs with Internal Reference and I2C Interface

General Description

The MAX5823/MAX5824/MAX5825 8-channel, low-power,

8-/10-/12-bit, voltage-output digital-to-analog converters

(DACs) include output buffers and an internal 3ppm/°C

reference that is selectable to be 2.048V, 2.500V, or

4.096V. The MAX5823/MAX5824/MAX5825 accept a

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

low power (6mW) 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 MAX5823/MAX5824/MAX5825 have an I2C-compatible,

2-wire interface that operates at clock rates up to

400kHz. The DAC output is buffered and has a low sup-

ply current of less than 250FA per channel and a low

offset error of Q0.5mV (typ). On power-up, the MAX5823/

MAX5824/MAX5825 reset the DAC outputs to zero or mid-

scale based on the status of M/Z logic input, providing

flexibility for a variety of control applications. The internal

reference is initially powered down to allow use of an

external reference. The MAX5823/MAX5824/MAX5825

allow simultaneous output updates using software LOAD

commands or the hardware load DAC logic input (LDAC).

The MAX5823/MAX5824/MAX5825 feature a watchdog

function which can be enabled to monitor the I/O inter-

face for activity and integrity.

A clear logic input (CLR) allows the contents of the CODE

and the DAC registers to be cleared asynchronously and

simultaneously sets the DAC outputs to the program-

mable default value. The MAX5823/MAX5824/MAX5825

are available in a 20-pin TSSOP and an ultra-small,

20-bump WLP package and are specified over the -40NC

to +125NC temperature range.
