AFE781H1RRUR - Low-Power DACs With Internal HART® Modem, Voltage Reference, and Diagnostic ADC for 4mA to 20mA Loop-Powered Applications
Part Number: AFE781H1RRUR
Package: WFQFN-24
Type: Digital To Analog Converters
Description: Low-Power DAC and Diagnostic ADC 2 Channel AFE 24-WFQFN (4x4)
Product Overviews
AFE781H1RRUR is highly-integrated, high-accuracy, extremely low-power digital-to-analog converters (DACs) with voltage outputs designed for HARTenabled sensor-transmitter applications. The AFEx81H1 devices include most of the components required to design a 4mA to 20mA, 2‑wire (loop-powered) sensor transmitter. In addition to the highly accurate DAC, these parts include a HART-certified FSK modem, 10‑ppm/°C voltage reference, and diagnostic analog-to-digital converter (ADC).
Product Features
• Low quiescent current: 180µA (typical)
• 12-bit 3.84kSPS ADC for advanced diagnostics
• Integrated 1.25V reference at 10 ppm/°C (max)
• Internal 1.2288MHz oscillator with clock output
• Digital interface
– Serial peripheral interface (SPI): Shared bus for both DAC and HART
– Universal asynchronous receiver-transmitter (UART): Shared bus for both DAC and HART
– Both: SPI for DAC and UART for HART
• Fault detection: CRC bit error checking, windowed watchdog timer, diagnostic ADC
• Digital DAC slew-rate control
• Wide operating temperature: –55°C to +125°C
Applications
• 2-wire, 4-mA to 20-mA loop-powered transmitters
• Process control and industrial automation
• Smart transmitters
