Subject: [PATCH v2 8/9] iio: adc: ad7173: Add support for AD411x devices
Date: Tue, 14 May 2024 10:22:53 +0300 [thread overview]
Message-ID: <20240514-ad4111-v2-8-29be6a55efb5@analog.com> (raw)
In-Reply-To: <20240514-ad4111-v2-0-29be6a55efb5@analog.com>
From: Dumitru Ceclan <dumitru.ceclan@analog.com>
Add support for AD4111/AD4112/AD4114/AD4115/AD4116.
The AD411X family encompasses a series of low power, low noise, 24-bit,
sigma-delta analog-to-digital converters that offer a versatile range of
specifications.
This family of ADCs integrates an analog front end suitable for processing
both fully differential and single-ended, bipolar voltage inputs
addressing a wide array of industrial and instrumentation requirements.
- All ADCs have inputs with a precision voltage divider with a division
ratio of 10.
- AD4116 has 5 low level inputs without a voltage divider.
- AD4111 and AD4112 support current inputs (0 mA to 20 mA) using a 50ohm
shunt resistor.
