iio: dac: adding support for Microchip MCP47FEB02

2025-12-31T17:59:18Z

This is the iio driver for Microchip MCP47F(E/V)B(0/1/2)1, MCP47F(E/V)B(0/1/2)2, MCP47F(E/V)B(0/1/2)4 and MCP47F(E/V)B(0/1/2)8 series of buffered voltage output Digital-to-Analog Converters with nonvolatile or volatile memory and an I2C Interface. The families support up to 8 output channels. The devices can be 8-bit, 10-bit and 12-bit. Signed-off-by: Ariana Lazar Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron

iio: dac: ad5446: Separate I2C/SPI into different drivers

2025-11-09T16:15:13Z

Properly separate the I2C and SPI drivers into two different drivers living in their own source file (as usual). So that no need for the hacky ifdefery. Signed-off-by: Nuno Sá Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron

iio: dac: ad3530r: Add driver for AD3530R and AD3531R

2025-05-21T13:20:29Z

The AD3530/AD3530R (8-channel) and AD3531/AD3531R (4-channel) are low-power, 16-bit, buffered voltage output DACs with software- programmable gain controls, providing full-scale output spans of 2.5V or 5V for reference voltages of 2.5V. These devices operate from a single 2.7V to 5.5V supply and are guaranteed monotonic by design. The "R" variants include a 2.5V, 5ppm/°C internal reference, which is disabled by default. Support for monitoring internal die temperature, output voltages, and current of a selected channel via the MUXOUT pin using an external ADC is currently not implemented.

iio: dac: Support ROHM BD79703 DAC

2024-12-28T14:28:14Z

The ROHM BD79703 is a 6 channel digital to analog converter. Based on the data-sheet examples the hardware would support setting the DAC word without changing the actual output. The data-sheet is not too specific on how the enabling the output of new voltage set by DAC should be done - hence this is not implemented by the driver. The BD79703 would also support two specific "PULL_DOWN" modes. These aren't currently supported by the driver either. Add a very basic support for controlling the channel outputs one-by-one.

iio: dac: ad3552r: add high-speed platform driver

2024-11-03T20:33:32Z

Add High Speed ad3552r platform driver. The ad3552r DAC is controlled by a custom (fpga-based) DAC IP through the current AXI backend, or similar alternative IIO backend. Compared to the existing driver (ad3552r.c), that is a simple SPI driver, this driver is coupled with a DAC IIO backend that finally controls the ad3552r by a fpga-based "QSPI+DDR" interface, to reach maximum transfer rate of 33MUPS using dma stream capabilities. All commands involving QSPI bus read/write are delegated to the backend through the provided APIs for bus read/write.

iio: dac: support the ad8460 Waveform DAC

2024-09-30T08:21:03Z

The AD8460 is a “bits in, power out” high voltage, high-power, high-speed driver optimized for large output current (up to ±1 A) and high slew rate (up to ±1800 V/μs) at high voltage (up to ±40 V) into capacitive loads. A digital engine implements user-configurable features: modes for digital input, programmable supply current, and fault monitoring and programmable protection settings for output current, output voltage, and junction temperature. The AD8460 operates on high voltage dual supplies up to ±55 V and a single low voltage supply of 5 V.

The AD9739A is a 14-bit, 2.5 GSPS high performance RF DACs that are capable of synthesizing wideband signals from DC up to 3 GHz. A dual-port, source synchronous, LVDS interface simplifies the digital interface with existing FGPA/ASIC technology. On-chip controllers are used to manage external and internal clock domain variations over temperature to ensure reliable data transfer from the host to the DAC core.
