LTC2755BCUP-16#PBF

LTC2755BCUP-16#PBF is a quad 16bit multiplying parallel-input, current-output DAC. This DAC operates from a single 2.7V to 5.5V supply and are all guaranteed monotonic over temperature. The LTC2755A-16 provides 16bit performance (±1LSB INL and DNL) over temperature without any adjustments. This SoftSpan™ DAC offers six output ranges two unipolar and four bipolar that can be programmed through the parallel interface, or pinstrapped for operation in a single range. This LTC2755 DAC uses a bidirectional input/output parallel interface that allows readback of any internal register, including the DAC output span settings. A power-on reset circuit resets the DAC outputs to 0V when power is initially applied. A logic low on the CLR pin asynchronously clears the DACs to 0V in any output range. Applications include high-resolution offset and gain adjustment, process control and industrial automation, automatic test equipment, and data acquisition systems.
