DESCRIPTION

Quad 12-/16-Bit

serial-input, current-output digital-to-analog converters.

They operate from a single 3V to 5V supply and are guar-

anteed monotonic over temperature. The LTC2754A-16

provides full 16-bit performance (±1LSB INL and DNL,

max) over temperature without any adjustments. These

SoftSpan™ DACs offer six output ranges (up to ±10V) that

can be programmed through the 3-wire SPI serial interface,

or pinstrapped for operation in a single range.

The content of any on-chip register (including DAC out-

put-range settings) can be verified in just one instruction

cycle; and if you change any register, that register will be

automatically read back during the next instruction cycle.

Voltage-controlled offset and gain adjustments are also

provided; and the power-on reset circuit and CLR pin both

reset the DAC outputs to 0V regardless of output range.

0V to 5V, 0V to 10V, –2.5V to 7.5V, ±2.5V, ±5V, ±10V
