AD5381BSTZ-5KL2 Présentation
A digital-to-analog converter (DAC) is an electronic component that converts digital binary data into an analog voltage or current. The AD5381 is a denseDAC, integrating 40 DAC channels in a single package, which reduces board space and system cost compared to using multiple lower-channel-count DACs. It belongs to the family of data converters, which are essential in bridging the digital and analog domains in mixed-signal systems. The AD5381's high channel density and integrated reference make it a key component in multichannel control and calibration systems.
Key features of the AD5381BSTZ-5KL2 include 12-bit resolution, 40 independent output channels, rail-to-rail output amplifiers, and a programmable reference. The device offers a settling time of 8 µs typical, ensuring fast response in dynamic applications. It also includes a power-on reset to zero-scale, ensuring safe startup conditions. The channel monitor function allows external monitoring of any channel without disturbing the output, which is valuable for system diagnostics.
Technically, the AD5381 uses a segmented architecture with an internal precision reference, achieving excellent linearity and low noise. The device operates over a temperature range of -40°C to +105°C, making it suitable for industrial environments. The LQFP-100 package provides a compact footprint while allowing adequate thermal dissipation. The digital interface supports both parallel and serial modes, with the SER/PAR pin selecting the mode, and the SPI/I2C pin (Pin 97) enabling the serial interface when tied low.
Typical applications include industrial process control (e.g., valve and actuator control), automatic test equipment (ATE) for precise voltage generation, and medical instrumentation such as patient monitoring systems. The AD5381's 40 channels allow it to drive multiple analog outputs simultaneously, reducing component count and improving system reliability.
When designing with the AD5381, ensure proper decoupling of the AVDD and DVDD supplies with 10 µF and 0.1 µF capacitors placed close to the pins. The reference output should be buffered if external loads are connected. The MON_OUT pin can be used to monitor channel outputs, but care must be taken to avoid loading the monitored channel.

Principaux différenciateurs
- 40-channel density in a single LQFP-100 package (vs AD5382BSTZ-5 (32 channels))
- 12-bit resolution with 8 µs settling time (vs AD5380BSTZ-5 (14-bit, 10 µs))

Notes de conception
Decouple the AVDD and DVDD pins with 10 µF and 0.1 µF capacitors placed as close to the pins as possible. Use separate analog and digital ground planes to minimize noise coupling. The AD5381 operates from a single 5 V supply; ensure the supply is clean and stable to maintain DAC accuracy.
For the LQFP-100 package, use a solid ground plane under the device to aid thermal dissipation and reduce parasitic inductance. Route analog output traces away from digital lines to prevent crosstalk. Keep the reference input/output traces short and shielded if possible.
Ensure the SER/PAR pin is set correctly for the desired interface mode. In serial mode, tie the SPI/I2C pin (Pin 97) low to enable SPI. Do not leave the LDAC pin floating; tie it low for immediate updates or use it for synchronized updates. Verify the power-on reset state is zero-scale to avoid unexpected outputs.
