TPC116S8U/ TPC112S8U
3PEAK
Octal 16-/12-Bit, Low Power, High Performance DACs
The TPC116S8U/TPC112S8U are pin compatible 16-bit
and 12-bit digital-to-analog converter, these series
product are eight 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.

Low Power Consumption (1.6 mA typ)
Differential Nonlinearity: ±1LSB(max)
Glitch Energy: 2nV-s
The TPC116S8U/ TPC112S8U 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.
Power-On Reset to Zero
Supply Range: 2.7V to 5.5V
◼
Buffered Rail-to-Rail Output Operation
The TPC116S8U/ TPC112S8U 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
TPC116S8U/ TPC112S8U 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.
