概述

The TPC2221 is an all-in-one, loop-powered digital-toanalog converter (DAC) that is tailored to the requirements of intelligent sensor manufacturers within the industrial automation sector.This DAC offers a highly accurate, fully integrated, and cost-effective solution in a compact TSSOP package.

It features a built-in voltage regulator that not only powers the TPC2221 but also other components within the sensor, providing a stable output voltage between 1.8 V and 12 V.The TPC2221 also incorporates 1.915 V and 2.5 V reference voltages, which means there's no need for additional discrete regulators or voltage references.

It is fully compatible with the standard HART® FSK protocol used in remote sensor communication without any loss in performance.The device's highspeed serial interface operates at 30 MHz and supports easy integration with popular microprocessors and microcontrollers through a SPI-compatible, 3-wire interface.

The TPC2221 ensures monotonicity up to 16 bits and delivers exceptional performance with 0.0015% integral nonlinearity, 0.0012% offset error, and 0.0006% gain error under typical operating conditions.

Lastly, the TPC2221 is offered in a 28-lead TSSOP package and is designed to operate over an extended industrial temperature range from −40°C to +125°C.
