Subject: [PATCH v11 2/3] dt-bindings: iio: add AD74413R
Date: Sun, 5 Dec 2021 13:40:44 +0200 [thread overview]
Message-ID: <20211205114045.173612-3-cosmin.tanislav@analog.com> (raw)
In-Reply-To: <20211205114045.173612-1-cosmin.tanislav@analog.com>
The AD74412R and AD74413R are quad-channel, software configurable,
input/output solutions for building and process control applications.
They contain functionality for analog output, analog input, digital input,
resistance temperature detector, and thermocouple measurements integrated
into a single chip solution with an SPI interface.
The devices feature a 16-bit ADC and four configurable 13-bit DACs to
provide four configurable input/output channels and a suite of diagnostic
functions.
The AD74413R differentiates itself from the AD74412R by being
HART-compatible.
