Frequently Asked Questions
What is the resolution and sampling rate of the ADC124S021CIMM?
The ADC124S021CIMM provides 12-bit resolution with a maximum sampling rate of 200 ksps. It uses a successive approximation register (SAR) architecture with an internal track-and-hold circuit, delivering accurate conversions across its full 50 ksps to 200 ksps specified range.
How many input channels does the ADC124S021CIMM support and how are they selected?
The ADC124S021CIMM supports 4 analog input channels (IN1 through IN4) through an internal multiplexer. Channel selection is controlled digitally via the SPI-compatible serial interface, allowing the host microcontroller to switch between channels on a per-conversion basis.
What is the power consumption of the ADC124S021CIMM?
Normal power consumption is 2.2 mW with a 3V supply and 7.9 mW with a 5V supply. The device features an automatic power-down mode that reduces consumption to just 0.14 µW at 3V or 0.32 µW at 5V, making it highly suitable for battery-powered applications.
What serial interfaces are compatible with the ADC124S021CIMM?
The ADC124S021CIMM outputs straight binary data through a serial interface compatible with SPI, QSPI, MICROWIRE, and many common DSP serial interfaces. This broad compatibility simplifies integration with microcontrollers, DSPs, and FPGAs without requiring additional interface logic.
What are suitable alternatives to the ADC124S021CIMM?
Compatible alternatives include the ADC104S021 (same family, 10-bit resolution, lower cost), ADC084S021 (8-bit, 4-channel variant), and the MCP3204 from Microchip which offers similar 4-channel 12-bit SPI ADC functionality. Selection depends on resolution requirements and power budget.
