LTC2688 Digital-to-Analog Converter (DAC) | Datasheet Preview

Analog Device's LTC2688 is a 16-channel, 16-bit precision, ±15 V digital-to-analog converter 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. The SoftSpan™ DAC offers five output ranges up to ±15 V that are independently programmable. The internal reference sets the accuracy of the output voltage. Three toggle pins support Input Register A and Input Register B toggle or sinusoidal dither at multiple frequencies. An analog multiplexer simplifies measurement of pin voltages, load currents, and junction temperature. The serial peripheral interface (SPI) and MICROWIRE™-compatible, 3-wire serial interface operate on logic levels as low as 1.71 V and clock rates up to 50 MHz. In a small LFCSP package, the LTC2688 is used for various voltage mode biasing applications such as optical modulators, automatic test equipment, data acquisition systems, and more.
