Data sheet:
The 16-bit AFE882H1 and 14-bit AFE782H1 (AFEx82H1) are highly-integrated, high-accuracy, extremely low-power DACs with voltage-outputs designed for HART-enabled process control and industrial automation applications.
The AFEx82H1 devices include most of the components required to design a 4‑mA to 20‑mA, 3‑wire or 4-wire sensor transmitter or analog output module. In addition to the highly accurate DAC, these devices include a HART®-compliant FSK modem, 10-ppm/°C voltage reference, and diagnostic analog-to-digital converter (ADC). To accommodate intrinsic and functional safety concerns, external voltage-to-current conversion and power-regulation are required.
The internal diagnostic ADC is multiplexed to several internal nodes that enable an automatic self-health check. This check is capable of detecting errors or malfunctions of the internal bias sources, power regulator, voltage reference, DAC output, die temperature, and optional external voltage source. If any fault is detected from the diagnostic ADC, CRC frame-error checking, or windowed watchdog timer, the devices can optionally issue an interrupt, enter a user-specified fail-safe state, or both.
- Functional Safety-Capable
- Low quiescent current: 180 µA (typical)
- HART-compliant physical layer modem
- Programmable amplitude of TX signals
- RX demodulator and band-pass filter
- 16-bit or 14-bit monotonic high-performance DAC
- DAC output range: 0 V to 2.5 V
- Digital DAC slew-rate control
- 4-LSB INL at 16 bits
- 0.07% FSR (max) TUE from –40°C to +125°C
- 12-bit 3.84-kSPS ADC for advanced diagnostics
- Integrated 1.25-V reference at 10 ppm/°C (max)
- Internal 1.2288-MHz 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
- Wide operating temperature: –55°C to +125°C
