They are guaranteed monotonic and have built-in rail-to-rail output buffers.
These SoftSpan™ 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 command.
The SPI/Microwire-compatible 3-wire serial interface operates on logic levels as low as 1.
71V at clock rates up to 50MHz.
