nn 32-Lead (5mm × 5mm) QFN Package The LTC®2666 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. nn The integrated 2.5V reference is buffered separately to each …
