DAC8534

SBAS254D – SEPTEMBER 2002 – REVISED MARCH 2004

Quad Channel, Low Power, 16-Bit, Serial Input

DIGITAL-TO-ANALOG CONVERTER

DESCRIPTION

FEATURES

The DAC8534 is a quad channel, 16-bit Digital-to-Analog

Converter (DAC) offering low-power operation and a flexible

serial host interface. Each on-chip precision output amplifier

allows rail-to-rail output swing to be achieved over the supply

range of 2.7V to 5.5V. The device supports a standard 3-wire

serial interface capable of operating with input data clock

frequencies up to 30MHz for IOV_DD= 5V.

ꢀ POWER SUPPLY: +2.7V to +5.5V

ꢀꢀmicroPOWER OPERATION: 950µA at 5V

ꢀ 16-BIT MONOTONIC OVER TEMPERATURE

ꢀ SETTLING TIME: 10µs to ±0.003% FSR

ꢀ ULTRA-LOW AC CROSSTALK: –100dB typ

ꢀ POWER-ON RESET TO ZERO-SCALE

The DAC8534 requires an external reference voltage to set

the output range of each DAC channel. Also incorporated

into the device is a power-on reset circuit which ensures that

the DAC outputs power up at zero-scale and remain there

until a valid write takes place. The DAC8534 provides a per

channel power-down feature, accessed over the serial inter-

face, that reduces the current consumption to 200nA per

channel at 5V.

ꢀ ON-CHIP OUTPUT BUFFER AMPLIFIER WITH

RAIL-TO-RAIL OPERATION

ꢀ DOUBLE BUFFERED INPUT ARCHITECTURE

ꢀ SIMULTANEOUS OR SEQUENTIAL OUTPUT

UPDATE AND POWER-DOWN

ꢀ 16 CHANNEL BROADCAST CAPABILITY

ꢀ SCHMITT-TRIGGERED INPUTS

ꢀ TSSOP-16 PACKAGE

The low-power consumption of this device in normal opera-

tion makes it ideally suited to portable battery-operated

equipment and other low-power applications. The power

consumption is 5mW at 5V, reducing to 4µW in power-down

mode.

APPLICATIONS

ꢀ PORTABLE INSTRUMENTATION

ꢀ CLOSED-LOOP SERVO-CONTROL

ꢀ PROCESS CONTROL

The DAC8534 is available in a TSSOP-16 package with a

specified operating temperature range of –40°C to +105°C.
