Frequently Asked Questions
What resolution and input range does the AD7843ARQZ-REEL7 provide?
The AD7843ARQZ-REEL7 is a 12-bit successive-approximation ADC with 4 analog input channels and a 3.6 V maximum analog input voltage, delivering a typical linearity error of no more than 0.0488% for accurate touch-position digitization.
How is the AD7843ARQZ-REEL7 packaged for surface mount assembly?
This touch screen digitizer ships in a 16-pin SSOP package (JESD-30 code R-PDSO-G16, JESD-609 code e3), providing a compact surface-mount footprint that supports the part's 4 analog input channels in a small board area.
Is the AD7843ARQZ-REEL7 RoHS lead-free compliant?
Analog Devices lists the AD7843ARQZ-REEL7 as non-lead-free (Pbfree Code: No, JESD-609 code e3), so RoHS-restricted buyers of this 12-bit, 16-pin touch controller should confirm the exact finish and date code before committing to production orders.
