DIP 28 Pin High IC Chip


20MHz High IC Chip






The AD5544/AD5554 quad, 16-/14-bit, current output, digital

to-analog converters (DACs) are designed to operate from a

2.7 V to 5.5 V supply range.

The applied external reference input voltage (VREFx) determines

the full-scale output current. Integrated feedback resistors (RFB)

provide temperature-tracking, full-scale voltage outputs when

combined with an external I-to-V precision amplifier.

A double-buffered serial data interface offers high speed, 3-wire,

SPI- and microcontroller-compatible inputs using serial data in

(SDI), a chip select (CS), and clock (CLK) signals. In addition,

a serial data out pin (SDO) allows for daisy-chaining when multiple

packages are used. A common, level-sensitive, load DAC strobe

(LDAC) input allows the simultaneous update of all DAC outputs

from previously loaded input registers. Additionally, an internal

power-on reset forces the output voltage to 0 at system turn-on.

The MSB pin allows system reset assertion (RS) to force all registers

to zero code when MSB = 0 or to half-scale code when MSB = 1.



AD5544: 16-bit resolution INL of ±1 LSB (B Grade)

AD5554: 14-bit resolution INL of ±0.5 LSB (B Grade)

2 mA full-scale current ± 20%, with VREF = ±10 V , 0.9 µs settling time to ±0.1%

12 MHz multiplying bandwidth ,Midscale glitch of −1 nV-sec

Midscale or zero-scale reset ,4 separate, 4-quadrant multiplying reference inputs

SPI-compatible, 3-wire interface ,Double-buffered registers enable

Simultaneous multichannel change ,Internal power-on reset

Temperature range: −40°C to +125°C
