AD5504

PRODUCTION

High Voltage, Quad Channel 12-Bit Voltage Output DAC

Viewing:

Overview

  • Quad channel high voltage DAC
  • 12-bit resolution
  • Pin selectable 30 V or 60 V output range
  • Integrated Precision Reference
  • Low power serial interface with readback capability
  • Integrated Temperature Sensor Alarm function
  • Power-On Reset
  • Simultaneous updating via LDAC
  • Wide operating temperature: −40°C to +105°C

The AD5504 is a quad-channel, 12-bit, serial input, digital-to-analog converter with on-chip high voltage output amplifiers and an integrated precision reference. The DAC output voltage ranges are programmable via the range select pin (R_SEL). If R_SEL is held high, the DAC output ranges are 0 V to 30 V. If R_SEL is held low, the DAC output ranges are 0 V to 60 V. The on-chip output amplifiers allow an output swing within the range of AGND + 0.5 V to VDD − 0.5 V.

The AD5504 has a high speed serial interface, which is com-patible with SPI®-, QSPI™-, MICROWIRE™-, and DSP-interface standards and can handle clock speeds of up to 16.667 MHz.

    Precision DAC Error Budget Tool

    The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
