Typical Application

Description

The LTC2754 is a family of quad 12- and 16-bit multiplying serial-input, current-output digital-to-analog converters. They operate from a single 3V to 5V supply and are guaranteed monotonic over temperature. The LTC2754A-16 provides full 16-bit performance (¡À1LSB INL and DNL, max) over temperature without any adjustments. These SoftSpan DACs offer six output ranges (up to ¡À10V) 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 output- 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.
