Octal 16‐/12‐Bit, Low Power, High Performance DACs
The TPC116S8/TPC112S8 are pin compatible 16-bit
and 12-bit digital-to-analog converter, these series
product are four channels, 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
TPC116S8/ TPC112S8
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 TPC116S8/ TPC112S8 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 TPC116S8/
TPC112S8 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 TPC116S8/ TPC112S8 are available in a small
size 16-pin TSSOP package, all package are specified
over the -40°C to +125°C extended industrial
temperature range.

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum
Rating condition for extended periods may affect device reliability and lifetime.
Note 2:
The supplies must be established simultaneously, with, or before, the application of any input signals.
Note 3:
The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power supply, the input
current should be limited to less than 10mA.
Note 4:
A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many
amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces
connected to the leads.
