SoftSpan DACs with
10ppm/°C Max Reference
Description
The
LTC
®
2668
is a family of 16-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 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.
