16-bit quad DAC with SoftSpan programmability
The LTC2755ACUP-16#PBF is a 16-bit, 4-channel multiplying DAC from Analog Devices' SoftSpan series, delivering current-unbuffered output with a typical settling time of 2 µs. Each of the four DACs can be independently programmed for unipolar or bipolar output ranges via the SoftSpan interface, eliminating external gain-setting resistors for multi-range designs. The parallel data interface and external reference allow direct connection to a 16-bit bus without serial latency, making it suitable for ATE, instrumentation, and industrial control loops where deterministic update timing matters.
Linearity and monotonicity for precision loops
The multiplying DAC architecture accepts an AC or DC reference and produces an output proportional to the reference times the digital code, enabling applications like programmable gain amplifiers, sine-wave synthesis, and automatic gain control loops.
Package, footprint, and thermal management
The tube packaging suits prototype and low-volume builds; for reflow assembly, the QFN's 0.5 mm pitch demands a solder-paste stencil aperture matched to the land pattern recommended in the package drawing.
Active lifecycle and compliance documentation
The ROHS3 compliance covers the full substance restriction including the four phthalates, so the part meets current EU and China RoHS requirements without exemption declarations.
