16-bit dual multiplying DAC with 2 µs settling
The Analog Devices LTC2752ACLX#PBF is a 16-bit, dual-channel, current-output multiplying DAC from the SoftSpan™ series. It delivers a typical settling time of 2 µs and integrates an SPI data interface, making it suited for precision control loops, programmable attenuators, and arbitrary waveform generation where two synchronized analog outputs are needed. The multiplying DAC architecture accepts an external reference voltage that can vary dynamically, so the output current scales with the reference — useful for AC signal scaling or programmable gain stages where the reference is not a fixed DC level. Linearity is specified at ±0.4 LSB INL and ±0.2 LSB DNL, which ensures monotonic behavior and predictable output across the full 16-bit code range — important for closed-loop position control or precision calibration sources.
It is not rated for extended industrial or automotive use where ambient temperatures exceed 70°C.
Package and footprint — 48-LQFP (7x7)
The fine-pitch QFP requires careful solder-paste stencil design and reflow profiling per the manufacturer's recommendations — MSL level should be verified from the lot date code to determine bake requirements before reflow.
