AD3532RBCPZ

AD3532RBCPZ is a 16-channel, 16-bit voltage output 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 range. AD3532R also offer 2.5V, 5ppm/°C internal references that are disabled by default. The devices include integrated multiplexers that allow monitoring of output voltages, currents, and internal die temperature. The device incorporates power-on reset circuits that ensure that the DACs output power up to and present at 32kΩ to ground until a valid write is executed. The DAC also contain power-down modes that reduce the current consumption down to 1.34mA, typical. The SPI and MICROWIRE®-compatible, 4-wire serial interface operate on logic levels as low as 1.08V up to 1.98V and clock rates up to 50MHz. Typical applications include optical transceivers, test and measurement, industrial automation and data acquisition systems.
