Chinese analog and mixed-signal IC supplier 3PEAK has launched a new high-precision, four-channel digital-to-analog converter (DAC), the TPC2884. Designed to meet the stringent requirements of industrial automation, PLC/DCS, and process control systems, the chip delivers exceptional accuracy and stability for critical control applications.
The TPC2884 stands out with several leading-edge specifications aimed at solving common industrial design challenges:
Superior Accuracy: The device achieves outstanding output precision with a voltage output temperature drift of 0.025% and a current output drift of 0.09% across an extended temperature range of -40°C to 105°C.
Robust Power Management: It is optimized for power cycling, with very low transient glitches during power-on/off (0.7mV for voltage, 0.8μA for current), ensuring stable output even during unexpected power loss.
Thermal Management: An integrated adaptive power-temperature control solution reduces chip temperature rise by approximately 20°C under a demanding four-channel, 20mA short-circuit condition, significantly enhancing long-term system reliability.
The 16-bit DAC offers great flexibility, supporting various output ranges including 4mA–20mA, 0mA–20mA for current, and 0V–5V, ±10V for voltage. It also includes a suite of integrated features for robustness and diagnostics: a 12-bit built-in ADC for output monitoring and error detection, along with comprehensive protection mechanisms like CRC checks, a watchdog timer, and overtemperature protection. It operates over a -40°C to 125°C range in a compact QFN48 package.
