Part Number: LTC2688HUJ-12

Package: WFQFN-40

Type: Digital To Analog Converters

Description: Digital to Analog Converters - DAC, 16-Channel

Product Overviews

LTC2688HUJ-12 is a 16-channel, 16-bit, ±15 V digital-to-analog converter (DAC) with an integrated precision reference. The LTC2688 is guaranteed monotonic and has built in rail-to-rail output buffers that can source or sink up to 20 mA. This SoftSpan™ DAC offers five output ranges up to ±15 V. The range of each channel is independently programmable. The internal 4.096 V precision reference sets the accuracy of the output voltage. An external reference can be used for additional range options. Three toggle pins support Input Register A and Input Register B toggle or sinusoidal dither at multiple frequencies.
