AD5622AKSZ-2REEL7 is a high precision, low power, balanced current-output, dual digital-to-analog converter (DAC). It is characterized by excellent ac performance, low noise, low power consumption and low voltage requirements.

The AD5622AKSZ-2REEL7 provides simultaneous, balanced, current-output updates, making it an ideal choice for high precision applications such as data acquisition, industrial process control, automotive, and avionics. It is available in the RoHS compliant 16-lead SSOP package. With its on-board reference, the device can be powered from a single +3.3 V supply, or with external reference, from a +2.7 V to +3.3 V supply.

Application Fields:

The AD5622AKSZ-2REEL7 is suitable for applications that require current output, low noise, low power and high precision, including data acquisition, industrial process control, automotive, and avionics. With its programmable gain, the device can be used in high performance systems such as monitor, instrument, and adjustable current sources, while its small package size (only 16 pins) makes it an appealing choice for portable devices.

Working Principle:

The AD5622AKSZ-2REEL7 uses a combination of digital and analog circuitry in order to achieve data conversion. It has on-board EEPROM and temperature-compensated references, which allow for the addition of calibration data in order to improve accuracy. It has a programmable gain from 1 to 4, and is capable of delivering up to ±10 mA into 20 ohm loads without any additional external components. The device uses a two-step conversion process in which a digital command is first sent to the chip and the DACs, which generates the appropriate analog output and then sends it to the chosen current output stage.

The AD5622AKSZ-2REEL offers stable performance over temperature, with a rated power-up time of 50 ms at -40°C to 85°C. It also offers excellent long-term stability, with a total unadjusted error (TUE) of 0.1%. This combination of features ensures that the AD5622AKSZ-2REEL is an ideal solution for high performance, low-power data conversion.
