LTC2666CUH-16#PBF

LTC2666 is an 8-channel, 16bit digital-to-analogue converter with integrated precision references. It has a guaranteed monotonic and have built-in rail-to-rail output buffers. This SoftSpan™ DAC offer five output ranges upto ±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. It 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 upto 50MHz.
