Active 12-bit DAC in a compact SC-70-6
The AD5622BKSZ-2REEL7 is an active-production 12-bit digital-to-analog converter from the nanoDAC series, delivering a buffered voltage output via an I2C interface. Housed in a 6-lead SC-70-6 package, this DAC fits tight PCB layouts where board space is at a premium. The string-DAC architecture ensures inherent monotonicity, with INL of ±2 LSB max and DNL of ±1 LSB max — important for open-loop control loops where non-monotonic behavior could cause instability.
Supply, interface, and settling time for control loops
The I2C data interface operates at standard clock rates, requiring only two bus lines (SDA and SCL) for communication — a clean fit for mixed-signal boards where GPIO pins are scarce. The 10 µs settling time to ±½ LSB supports update rates suitable for set-point control in power supplies, sensor calibration, and trim applications. The reference is derived from the supply itself (supply-referenced architecture), so output accuracy tracks the rail — a consideration when the supply has ripple or droop under load.
Package variant and compliance
This order code is the tape-and-reel (TR) and cut-tape (CT) packaging option of the AD5622BKSZ-2 base device. The suffix -2REEL7 indicates reel packaging suitable for automated pick-and-place assembly; the cut-tape variant allows smaller-quantity prototyping.
