LTC2664CUH-16#PBF

LTC2664 is a four-channel, 16bit ±10V digital-to-analog converter with integrated precision references. It has guaranteed monotonic and built-in rail-to-rail output buffers. These SoftSpan™ DACs 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. It is used in applications such as optical networking, instrumentation, data acquisition, automatic test equipment, process control and industrial automation.
