The AD5663BRMZ-REEL7 is a versatile, high-precision, low-power, 16-bit digital-to-analog converter (DAC). It is appropriate for a variety of application fields such as consumer and industrial motor control, digital power supplies, instrumentation, audio and video signal processing, optoelectronic control, military/aerospace and medical applications.

The AD5663BRMZ-REEL7 comes with a single-channel voltage output and operates from a supply of 2.7V to 5.5V. It has flexible references, with an internal voltage reference and external buffered voltage reference available. It also has an integrated temperature sensor for thermal management.

The AD5663BRMZ-REEL7 allows for fast and accurate signal conditioning, with a typical small-signal bandwidth of 150 MHz and a signal-to-noise ratio of 107 dBmax. The output is protected against external over-voltage conditions, ESD and latch-up, with a wide range of output gain and offset programming capabilities. The device is specified for an operating temperature range of -40° C to +125° C.

The working principle of the AD5663BRMZ-REEL7 is based on a capacitive current-steering DAC architecture. It employs a digital-to-analog conversion process that works in two stages. In the first stage, a digital input code is converted to a reduced scale analog value at the MX + B input. A restricted range of up to three parts is used to reduce the overall resolution of the device. In the second stage, the current steering DAC is used to convert the output of the input-vector to an analog output voltage.

The AD5663BRMZ-REEL7 can provide accuracies of up to ± 1.0 LSB, with power consumption as low as typically 4.3 mW. The device comes in a 7-lead small outline integrated circuit (SOIC) package and is characterized for operation from -40° C to +125° C.
