LTC2668IUJ-12#PBF

LTC®2668 is a family of 16-channel, 16-/12-bit ±10V digital-to-analogue converter with integrated precision references. It is guaranteed monotonic and has built-in rail-to-rail output buffers. This SoftSpan™ DAC offers 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. This 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. Typical applications are optical networking, instrumentation, data acquisition, automatic test equipment, process control and industrial automation.
