Typical Application


The TPC116S1/TPC114S1/TPC112S1 are pin compatible12-bit, 14-bit and 16-bit digital-to-analog converter, these series product aresingle channel, low power, buffered voltage-out DACs and are guaranteed monotonicby design. The devices use a precision external reference applied through thehigh resistance input for rail-to-rail operation and low system power consumption.

The TPC116S1/TPC114S1/TPC112S1 accepts awide 2.7V to 5.5V supply voltage range. The parts incorporate a power-on resetcircuit to ensure that the DAC output powers up to 0 V and remains there untila valid write takes place. The parts contain a power-down feature that reducesthe current consumption of the device to 400 nA at 5 V and provides software-selectableoutput loads while i power-down mode. The power consumption is 0.45 mW at 5 V,reducing to 1μW in power-down mode.

The TPC116S1/TPC114S1/TPC112S1 on-chip precisionoutput amplifier allows rail-to-rail output swing to be achieved. For remotesensing applications, the output amplifier’s inverting input is available tothe user. The TPC116S1/TPC114S1/TPC112S1 use a versatile 3-wire serialinterface that operates at clock rates up to 30 MHz and is compatible withstandard SPI®, QSPI, MICROWIRE, and DSP interface standards. The TPC116S1/TPC114S1/TPC112S1 areavailable in an small size 8-pin MSOP package, all package are specified overthe -40°C to +125°C extended industrial temperature range.
