LTC2664CUH-12#PBF

LTC2664CUH-12#PBF is a four-channel, 12bit ±10V digital-to-analogue converter with integrated precision references. This device 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. The LTC2664 also includes A/B toggle capability via a dedicated pin or software toggle command. The SPI/Microwave-compatible 3-wire serial interface operates on logic levels as low as 1.71V at clock rates up to 50MHz. Applications include optical networking, instrumentation, data acquisition, automatic test equipment, process control and industrial automation.
