The LTC2635’s small size and internal reference are important for a variety of industrial, automotive and ATE applications. The LTC2635 offers 12-bit performance of ±2.5LSB (max) INL error and 3nV•s crosstalk, ensuring that a voltage change on one DAC has minimal effect on the other DACs. Operating from a single 2.7V to 5.5V supply, supply current is a low 125µA per DAC.
In addition to selecting one of three resolution options, designers can also choose between a 2.5V or 4.096V full-scale range, as well as power-up options for zero-scale, mid-scale or Hi-Z. The 16-pin 3mm x 3mm QFN package includes a hardware load-DAC (LDAC) pin, three address pins for selecting 27 unique I2C addresses, and a REFLO pin. The 10-pin MSOP package has just one address pin for selection of up to 3 unique addresses on the I2C bus. All LTC2635 options are guaranteed over the automotive (-40ºC to +125ºC) and commercial (0ºC to +70ºC) temperature ranges.
