Hi Jeff,
the ADC121S021 is a 12-bit converter. If you scale the resistive divider such that 16V = Full Scale input to the ADC121S021, you should have 4096 output codes which represent ~3.9mV/code.
Part Number: ADC121S021 Hi team,
I think this IC holds when CS goes LOW and performs conversion at 13CLK (HOLD TIME), but what is the maximum hold time?
When I send a clock (16CLK) 30 seconds after setting CS to LOW and look at the data, the value deviates…
Part Number: ADC121S021 Other Parts Discussed in Thread: ADC122S051 , ADC101S021 Hi team,
Will ADC121S021 continue to do conversions when CS/ pin is low?
Another 2-ch device ADC122S051 has below description stating that conversions continue as long as CS…
Part Number: ADC121S021 Other Parts Discussed in Thread: ADS7042 HI staff
In the current app, the NJL7502R phototransistor is directly connected to the analog input terminal of the LTC2361. ADC121S021 is selected instead of ADI's AD converter.
The…
Part Number: ADC121S021 Hello, I'm having troubles using the ADC. I'm measuring current values via a shunt and an amplificator (INA126U) which gives me an output between 0 and 1.5V (equivalent to 0 to 10A). That is the input of the ADC.
There…
Part Number: ADC121S021 Figure 1 "ADC121S021 Serial Timing Diagram" shows SCLK idling high; that is, it shows SCLK as already high when nCS goes low at the start of a data transfer, and it shows SCLK being brought high at the end of the data transfer…

Hi Team,
I want to know software compatibility of ADS12XS021 series.
Are following devices register compatible?
ADC121S021 ADC122S021 ADC124S021
If not, please let me know…
Hi Phil,
It doesn't seem like we have any 4 input channel device that has such large pad spacing. This 1 channel part, ADC121S021 , has a spacing of 0.45mm. There is also this 2 channel part, ADC122S021 .
Out of curiosity, what is your project application…
Part Number: ADC121S021 Other Parts Discussed in Thread: ADC121C021 I need to read this ADC121S021 with the GPIO pins of a microcontroller that runs at 4 MHz.
The input of the ADC is connected to a 100 kOhm/220nF filter. The application takes a single…
