概述

  • 16-bit resolution, ±3 LSB16 INL, ±1 LSB16 DNL
  • TUE: ±0.22% of FSR maximum
  • Offset error: ±1.5mV maximum
  • Gain error: ±0.26% of FSR maximum
  • Guaranteed sourcing current of 50mA
  • Ultra-low headroom: 25mV at 20mA load
  • 2.5V internal voltage reference, 5ppm/°C, typical
  • 62nV/√Hz noise spectral density (external reference)
  • 115nV/√Hz noise spectral density (internal reference)
  • Output voltage, current, and die temperature monitors
  • 50MHz SPI write and read
  • 2.7V to 5.5V power supply range
  • 1.2V or 1.8V compatible digital interface
  • Operating temperature range: −40°C to +125°C
  • Small package: 4mm × 4mm, 32-lead lead frame chip scale package (LFCSP)

The AD3532R is a 16-channel, 16-bit, buffered voltage output, digital- to-analog converter (DAC) that includes software-programmable gain controls that result in full-scale output spans of 2.5V or 5V for reference voltages of 2.5V. The device operates from single, 2.7V to 5.5V supply ranges and are guaranteed monotonic by design. The AD3532R also offers a 2.5V, 5ppm/°C internal reference that is disabled by default.

The device includes integrated multiplexers that allow monitoring of output voltages, currents, and internal die temperature. The AD3532R is available in a 4mm × 4mm, 32-lead lead frame chip scale package (LFCSP) package. The device incorporates power on reset (POR) circuits that ensure that the DAC outputs power up to and present at 32kΩ to ground until a valid write is executed. The DAC also contains power-down modes that reduce the current consumption down to1.34mA, typical.

The serial peripheral interface (SPI) and MICROWIRE®-compatible, 4-wire serial interface operates on logic levels as low as 1.08V up to 1.98V and clock rates up to 50MHz.

产品详情

This user guide details the operation of the EVAL-AD3532RARDZ for the AD3532R 16-bit, 16-channel, voltage output, digital-to-analog converter (DAC).

The EVAL-AD3532RARDZ allows users to quickly prototype the AD3532R circuits and reduce design time. The AD3532R operates from single 2.7V to 5.5V supply ranges. The AD3532R incorporates internal 2.5V references to give output voltages of 2.5V or 5V. The EVAL-AD3532RARDZ also incorporates an additional on-board voltage reference, the ADR4525.

The EVAL-AD3532RARDZ interfaces to the USB port of a PC via a system demonstration platform (SDP-K1) board. The Analysis |Control | Evaluation (ACE) software is available for download from the EVAL-AD3532RARDZ product page to use with the evaluation board to allow the user to program the AD3532R device. A peripheral module interface (PMOD) connection is also available to allow the connection of microcontrollers to the evaluation board without the SDP-K1 board. When a microcontroller is used through the PMOD connection, the SDP-K1 board must be disconnected, and the user is unable to operate the ACE software.

The EVAL-AD3532RARDZ is compatible with Analog Devices, Inc., SDP-K1 board, which must be purchased separately.

For full details, see the AD3532R data sheet, which must be used in conjunction with this user guide when using the EVALAD3532RARDZ.
