They are guaranteed monotonic and have built-in rail-to-rail output buffers. These Soft Span™ DACs offer five output ranges up to ±10V. The range of each channel is independently programmable, or the part can be hardware-configured for operation in a fixed range. The integrated 2.5V reference is buffered separately to each channel; an external reference can be used for additional range options. The LTC2664 also includes A/B toggle capability via a dedicated pin or software toggle mand. The SPI/Microwire-patible 3-wire serial interface operates on logic levels as low as 1.71V at clock rates up to 50MHz.
