LTC2668IUJ-16#PBF

数模转换器, 16 bit, SPI, 4.5V 至 5.5V, QFN, 40 引脚

The is a 16-channel 16-bit Digital-to-analog Converter DAC 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. The LTC2668 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.
