3 Description

The 16-bit AFE88201 and 14-bit AFE78201

(AFEx8201) are highly-integrated, high-accuracy,

extremely low-power digital-to-analog converters

(DACs) with voltage outputs designed for processcontrol

and industrial-automation applications.

The AFEx8201 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, the

AFEx8201 incorporate a 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 selfhealth

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.
