TPC112S1-VR 3peak Precision DAC

　　The TPC116S1/TPC114S1/TPC112S1 are pin compatible 12-bit,14-bit and 16-bit digital-to-analog converter,these series product are single channel,low power,buffered voltage-out DACs and are guaranteed monotonic by design.The devices use a precision external reference applied through the high resistance input for rail-to-rail operation and low system power consumption.The TPC116S1/TPC114S1/TPC112S1 accepts a wide 2.7V to 5.5V supply voltage range.The parts incorporate a power-on reset circuit to ensure that the DAC output powers up to 0 V and remains there until a valid write takes place.The parts contain a power-down feature that reduces the current consumption of the device to 400 nA at 5 V and provides software-selectable output loads while in 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 precision output amplifier allows rail-to-rail output swing to be achieved.For remote sensing applications,the output amplifier’s inverting input is available to the user.The TPC116S1/TPC114S1/TPC112S1 use a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI®,QSPI™,MICROWIRE™,and DSP interface standards.The TPC116S1/TPC114S1/TPC112S1 are available in an small size 8-pin MSOP package,all package are specified over the-40°C to+125°C extended industrial temperature range.
