Pin Description

The MAX5363/MAX5364MAX5365 employ a current-

steering DAC topology as shown in Figure 2. At the

core of the DAC is a reference voltage-to-current con-

verter (V/I) that generates a reference current. This current

is mirrored to 63 equally weighted current sources.

DAC switches control the outputs of these current mirrors

so that only the desired fraction of the total current-mirror

currents is steered to the DAC output. The current is

then converted to a voltage across a resistor, and this

voltage is buffered by the output buffer amplifier.

binary unipolar with 1LSB = (V

/64). The MAX5363/

REF

The MAX5363/MAX5364/MAX5365 voltage-output, 6-bit

DACs offer full 6-bit performance with less than 1LSB

integral nonlinearity error and less than 1LSB differen-

tial nonlinearity error, ensuring monotonic performance.

The devices use a simple 3-wire, SPI/QSPI/ MICROWIRE-

compatible serial interface that operates up to 10MHz.

The MAX5363/MAX5364/MAX5365 include an internal

reference, an output buffer, and three low-current shut-

down modes, making these devices ideal for low-

power, highly integrated applications. Figure 1 shows

the devices’ functional diagram.

MAX5364 have a full-scale output voltage of (+2V - 1LSB)

and (+4V - 1LSB), respectively, set by the internal refer-

ences. The MAX5365 has a full-scale output voltage of

(0.9

- 1LSB).

Output Buffer

The DAC voltage output is an internally buffered unity-

gain follower that slews up to 0.4V/ꢁs. The output can

swing from 0 to full scale. With a 1/4FS to 3/4FS output

transition, the amplifier outputs typically settle to

1/2LSB in less than 5ꢁs when loaded with 10kΩ in par-

allel with 50pF. The buffer amplifiers are stable with any
