Product Description
GENERAL DESCRIPTION The AD5544/AD5554 quad, 16-/14-bit, current output, digitalto-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.FEATURES 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 Compact 28-lead SSOP and 32-lead LFCSPProduct AttributesMfr | Microchip Technology |
