MAX5803/MAX5804/MAX5805

Ultra-Small, Single-Channel, 8-/10-/12-Bit Buffered Output

Voltage DACs with Internal Reference and I C Interface

General Description

Benefits and Features

The MAX5803/MAX5804 single-channel, low-power,

8-/10-/12-bit, voltage-output this is an addition to content

digital-to-analog converters (DACs) include output

buffers and an internal reference that is selectable to

be 2.048V, 2.500V, or 4.096V. The MAX5803/MAX5804/

MAX5805 accept a wide supply voltage range of 2.7V to

5.5V with extremely low power (< 1mW) 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.

S Single High-Accuracy DAC Channel

 12-Bit Accuracy Without Adjustments

 1 LSB INL Buffered Voltage Output

 Guaranteed Monotonic Over All Operating

Conditions

S Three Precision Selectable Internal References

 2.048V, 2.500V, or 4.096V

S Internal Output Buffer

 Rail-to-Rail Operation with External Reference

 6.3µs Settling Time

 Output Directly Drives 2kI Loads

The MAX5803/MAX5804/MAX5805 have an I C-

compatible, 2-wire interface that operates at clock rates

up to 450kHz. The DAC output is buffered and has

a low supply current of 155FA (typical at 3.5V) and a

low offset error of Q0.5mV (typical). On power-up, the

MAX5803/MAX5804/MAX5805 reset the DAC outputs

to zero, providing additional safety for applications that

drive valves or other transducers which need to be off on

power-up.

S Small, 10-Pin, 2mm x 3mm TDFN and 3mm x 5mm

µMAX Packages

S Wide 2.7V to 5.5V Supply Range

S Fast 400kHz I C-Compatible, 2-Wire Serial Interface

with Readback Capability

S Power-On-Reset to Zero-Scale DAC Output

S User-Configurable Asynchronous I/O Functions:

CLR, LDAC, GATE

The MAX5803/MAX5804/MAX5805 include

user-

configurable active-low asynchronous input, AUX for

additional flexibility. This input can be programmed to

asynchronously clear (CLR) or temporarily gate (GATE) the

DAC output to a user-programmable value. A dedicated

active-low asynchronous LDAC input is also included. This

allows simultaneous output updates of multiple devices.

S Three Software-Selectable Power-Down Output

Impedances: 1kI, 100kI, or High Impedance

S Low 155µA DAC Supply Current at 3V

The MAX5803/MAX5804/MAX5805 are available in 10-pin

TDFN/µMAX packages and are specified over the -40NC
