What are the key features of DAC8168IAPW?
- 14-bit resolution across 8 independent voltage-output channels with ultra-low glitch energy and 0.0244% maximum integral nonlinearity for precision multichannel analog control
- Integrated 2.5 V internal reference with 2 ppm/°C drift coefficient eliminates external reference components, reducing BOM cost and PCB area in 8-channel DAC designs
- Serial SPI-compatible binary input with output voltage range up to 5.5 V, packaged in a compact 14-pin TSSOP for space-constrained industrial and instrumentation analog output modules
What is DAC8168IAPW used for?
The DAC8168IAPW is used in precision industrial control systems where 8 independent analog voltage outputs with 14-bit resolution must drive actuators, set reference voltages, or control gain stages simultaneously from a single SPI bus. Its 2 ppm/°C internal reference makes it suitable for temperature-stable calibration signal generation in test instrumentation, automatic gain control circuits, and programmable power supply setpoints. The ultra-low glitch specification also benefits audio mixing applications and waveform generators requiring clean simultaneous updates across all 8 output channels.

Frequently Asked Questions
What resolution and linearity does the DAC8168IAPW provide across its 8 output channels?
The DAC8168IAPW provides 14-bit resolution on each of its 8 independent voltage-output channels, corresponding to a minimum step size of approximately 0.15 mV with a 2.5 V full-scale reference. The maximum integral nonlinearity error is 0.0244%, which equals about 4 LSB at 14-bit resolution, ensuring precision control for actuator drives, calibration outputs, and analog set-point generation in industrial and instrumentation applications.
How does the integrated 2.5 V internal reference of the DAC8168IAPW affect BOM cost and drift performance?
The on-chip 2.5 V reference with a 2 ppm/°C temperature coefficient means that over a 50°C temperature change the reference shifts only 0.25 mV, contributing less than 2 LSB drift at 14-bit resolution. This eliminates the need for an external precision voltage reference such as the REF5025, saving one component, its decoupling capacitors, and approximately 3 mm × 3 mm of PCB footprint in multichannel analog output designs.
What serial interface does the DAC8168IAPW use and at what clock rate can it be updated across all 8 channels?
The DAC8168IAPW uses a 3-wire SPI-compatible serial interface accepting binary-coded 24-bit words (8 address bits plus 14 data bits plus control) on a single MOSI line with a SYNC (chip select) and SCLK. The SPI clock can run at up to 50 MHz, allowing all 8 channels to be updated in 8 × 24 / 50 MHz = approximately 3.84 µs, which supports control loop update rates well above 100 kHz for simultaneous multichannel DAC refresh.
For a precision 8-axis motion controller requiring stable analog velocity references, why choose the DAC8168IAPW over discrete single-channel DACs?
The DAC8168IAPW integrates 8 matched 14-bit channels with a shared 2 ppm/°C internal reference in a single 14-pin TSSOP, replacing 8 discrete single-channel DACs plus an external reference, reducing PCB area from roughly 8 × 50 mm² to under 40 mm² total. Channel-to-channel gain matching and simultaneous update capability through a single SPI port ensure that all 8 velocity reference voltages remain synchronized within 14-bit accuracy, which is critical for multi-axis servo systems requiring coherent analog setpoints.
