Description

General part information

LTC2666 Series

The LTC2666 is a family of 8-channel, 16-/12-bit ±10V digital-to-analog converters with integrated precision references. They are guaranteed monotonic and have built-in rail-to-rail output buffers. These SoftSpan™DACs 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 LTC2666 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.ApplicationsOptical NetworkingInstrumentationData AcquisitionAutomatic Test EquipmentProcess Control and Industrial Automation
