描述 Description

The TPC116S4/TPC112S4 are pin-compatible 16-bit and 12-bit digital-to-analog converters. These products are four-channel, low-power, buffered voltage-out DACs, which are guaranteed monotonic by design. These devices use a precision external reference applied through the high-resistance input for rail-to-rail operation and low system power consumption.

The TPC116S4/TPC112S4 accept a wide range of 2.7 V to 5.5 V supply voltage. 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 TPC116S4/TPC112S4 on-chip precision output amplifiers allow rail-to-rail output swing to be achieved. For remote sensing applications, the output amplifier’s inverting input is available to the user. The TPC116S4/TPC112S4 use a versatile 3- wire serial interface that operate sat clock rating up to 30 MHz and are compatible with standard SPI?, QSPI? , MICROWIRE? , and DSP interface standards.

The TPC116S4/TPC112S4 are available in a small-sized 16-pin TSSOP package, all packages are specified over the -40°C to +125°C extended industrial temperature range.
