1ꢀ0, 12-Bit, Serial, 0oltage-Output DAC

General Description

Features

The MAX5312 12-bit, serial-interface, digital-to-analog

converter (DAC) provides bipolar ±5ꢀ to ±1±ꢀ oꢁtpꢁts

from ±12ꢀ to ±15ꢀ poꢂer-sꢁpplꢃ voltages, or a ꢁnipo-

lar 5ꢀ to 1±ꢀ oꢁtpꢁt from a single 12ꢀ to 15ꢀ poꢂer-

sꢁpplꢃ voltage.

♦ Unipolar or Bipolar Output-Voltage Ranges

♦ Guaranteed INL ≤ ±1 LSB (max)

♦ Guaranteed Monotonic: DNL ≤ ±1 LSB (max)

♦ 10µs Settling Time to 0.5 LSB

The MAX5312 featꢁres excellent linearitꢃ ꢂith both inte-

gral nonlinearitꢃ (INL) and differential nonlinearitꢃ (DNL)

gꢁaranteed to ±1 LꢄS (max). The device also featꢁres

a fast 1±µs to ±.5 LꢄS settling time, and a hardꢂare-

shꢁtdoꢂn featꢁre that redꢁces cꢁrrent consꢁmption to

3.5µA. The oꢁtpꢁt goes to midscale at poꢂer-ꢁp in

bipolar mode (±ꢀ), and to zero scale at poꢂer-ꢁp in

ꢁnipolar mode (±ꢀ). A clear inpꢁt (CLR) asꢃnchronoꢁslꢃ

clears the DAC register and sets the oꢁtpꢁt to ±ꢀ. The

oꢁtpꢁt can be asꢃnchronoꢁslꢃ ꢁpdated ꢂith the load

DAC (LDAC) inpꢁt.

♦ Low 3.5µA Shutdown Current

♦ 10MHz SPI-/QSPI-/MICROWIRE-Compatible Serial

Interface

♦ Power-On Reset Sets DAC Output to 0V

♦ Schmitt Trigger Inputs for Direct

Optocoupler Interface

The device featꢁres a 1±MHz ꢄPI™-/QꢄPI™-/

MICROWIRE™-compatible serial interface that oper-

ates ꢂith 3ꢀ or 5ꢀ logic. Additional featꢁres inclꢁde a

serial-data oꢁtpꢁt (DOUT) for daisꢃ chaining and read-

back fꢁnctions. The MAX5312 reqꢁires a 2ꢀ to 5.25ꢀ

external reference voltage and is available in a 16-pin

ꢄꢄOP package that operates over the extended -4±°C

to +85°C temperatꢁre range.

♦ Serial-Data Output Allows Daisy Chaining

of Devices

♦ Small 16-Pin SSOP
