description
LTC®The 2754 is a family of quad 12-bit and 16-bit multiply serial input, current output digital-to-analog converters. They operate from a single 3V to 5V supply and are guaranteed monotonicity over temperature. Without any regulation, the LTC2754A-16 provides full 16-bit performance over temperature (±1LSB INL and DNL, max). These SoftSpanTMThe DAC provides six output ranges (up to ±10V) that can be set through a 3-wire SPI serial interface, or it can be operated in one output range through pin strapping.
The contents of all on-chip registers, including the DAC output range setpoint, can be verified in only one instruction cycle; And if you change any register, it will be automatically read back in the next instruction cycle.
These devices also provide voltage-controlled offset and gain adjustment; Moreover, the power-on reset circuit andCLRThe pins reset the DAC output to 0V independent of the output range.
