3PEAK TPC112S1-VR

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 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 5V and provides software-selectable output loads while in power-down mode. The power consumption is 0.45 mW at 5V, 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.
