LTC2664IUH-16#PBF

LINEAR TECHNOLOGY  LTC2664IUH-16#PBF  数模转换器, 4通道, 16 bit, 串行, 4.5V 至 5.5V, ± 4.5V 至 ± 15.75V, QFN, 32 引脚 新

The is a quad, 16bit, ±10V SoftSpan DAC with integrated precision reference in 32 pin QFN package. It is monotonic over temperature and has built-in rail-to-rail output buffers. This SoftSpan DAC 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. Typical applications include optical networking, instrumentation, data acquisition, automatic test equipment, process control and industrial automation.
