LTC2668HUJ-16#PBF

LTC2668HUJ-16#PBF is a 16-channel, 16bit, ±10V digital-to-analogue converter with 10ppm/°C max integrated precision reference. They are guaranteed monotonic and have 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 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. Applications include optical networking, instrumentation, data acquisition, automatic test equipment, process control, and industrial automation.
