What is AD5648BRUZ-1REEL7 used for?
The AD5648BRUZ-1REEL7 is used in precision industrial process control and programmable power supply designs where 8 independent analog voltage setpoints must be generated simultaneously from a single SPI-controlled component. Its 5 ppm/°C on-chip reference and 14-bit resolution make it well suited for automatic test equipment, calibration instruments, and analog front-end control in medical imaging systems where long-term setpoint stability is critical. The device is also employed in multi-axis motion control systems and laser driver boards where independent DAC channels adjust bias currents or velocity references for each controlled axis.

Frequently Asked Questions
How many DAC channels does AD5648BRUZ-1REEL7 provide, and what is the output voltage range per channel?
The AD5648BRUZ-1REEL7 provides 8 independent DAC output channels, each capable of driving voltages from 0 V up to 5.5 V. With 14-bit resolution, each channel divides this range into 16384 steps, giving a minimum voltage step size of approximately 0.34 mV with a 5.5 V span. This resolution and 8-channel density make it ideal for multi-axis motion control, programmable attenuators, and multi-zone temperature setpoint controllers.
What is the drift specification of the on-chip reference in AD5648BRUZ-1REEL7, and why does it matter for long-term setpoint accuracy?
The on-chip voltage reference in AD5648BRUZ-1REEL7 has a temperature coefficient of 5 ppm/°C. Over a 50 °C temperature change, the reference voltage shifts by only 250 ppm (0.025%), which translates to a full-scale output error of approximately 1.4 mV on a 5.5 V range. This low drift eliminates the need for an external precision voltage reference in most industrial and instrumentation designs, reducing component count by at least 1 reference IC plus associated bypass capacitors per board.
How does AD5648BRUZ-1REEL7 interface with a microcontroller, and can multiple DACs be daisy-chained on one SPI bus?
The AD5648BRUZ-1REEL7 uses a standard 3-wire SPI serial interface with binary-coded 24-bit input words covering address, control, and 14-bit data fields. Multiple AD5648 devices can be daisy-chained on a single SPI bus by connecting DOUT of the first device to DIN of the next and asserting a shared SYNC (chip-select) signal across all devices simultaneously, allowing a microcontroller to update all 8 channels of all chained DACs with a single burst transaction. This scales the 8-output AD5648 to 16, 24, or more independent DAC channels without adding additional chip-select lines.
What linearity performance does AD5648BRUZ-1REEL7 offer, and is it sufficient for automated test equipment?
The AD5648BRUZ-1REEL7 specifies a maximum integral non-linearity (INL) of 0.0244%, which corresponds to approximately ±4 LSB at 14-bit resolution. For automated test equipment generating voltage stimulus signals for device calibration, this INL is generally acceptable when the downstream measurement instrument has higher linearity than the DAC's 0.0244% error. Engineers requiring tighter INL for metrology-grade ATE should consider the 16-bit AD5668 from the same Analog Devices denseDAC family, which achieves sub-LSB INL performance.
What does the REEL7 suffix in AD5648BRUZ-1REEL7 indicate about procurement, and what quantity is on the reel?
The 'REEL7' suffix indicates the component is packaged on a 7-inch (178 mm) tape-and-reel, which typically holds 1000 pieces for TSSOP-14 body sizes. This format is designed for automated SMT pick-and-place production and provides lower per-unit pricing than cut-tape or tube packaging. Distributors also commonly stock the AD5648BRUZ-1 in 250-piece reels or cut-tape for prototype and low-volume orders where purchasing a full 1000-piece reel is impractical.
