Dual and quad DACs guarantee 16-bit monotonicity over temperature

Linear Technology's LTC2602 dual and LTC2604 quad 16-bit VOUT DACs guarantee monotonic performance over temperature with differential non-linearity (DNL) of ±1LSBMAX, which is critical in control loop applications. Also available in 12-bit and 14-bit versions, these DACs feature an easy to use interface and buffered rail-to-rail outputs. A 3-wire serial interface controls each DAC, simplifying transmission through isolation barriers or to remote locations.
Each DAC can be simultaneously updated with a different input code, and they deliver rail-to-rail voltage outputs over a 2,5 V to 5,5 V supply range. A full-scale transition on one of the LTC2604 DACs causes less than 5 µV change in the other DAC, which effectively eliminates crosstalk as a source of error. The LTC2604 consumes only 250 µA per DAC, which drops to 0,25 µA per DAC in power-down mode.
The LTC2602 family is available in an 8-pin MSOP package, half the size of an SO-8. High resolution, small size and low power make these dual and quad DACs suited for digital calibration, portable instrumentation and industrial process control applications.
