Frequently Asked Questions
Q1: What does the “/2K5” suffix in ADS8344EB/2K5 mean?
A: “/2K5” stands for tape‑and‑reel package with 2500 pieces per reel. /1K is 1000pcs/reel; no suffix means tray packing. Same die and electrical performance.
Q2: Can ADS8344EB/2K5 work with 3V battery power supply?
A: Yes, supply range 2.7V‑5V, fully compatible with 3V / 3.3V battery‑powered designs.
Q3: How to configure analog input channels?
A: Controlled by serial commands, multiplexer supports 8 single‑ended inputs or 4 differential input pairs.
Q4: What is the difference between ADS8344EB and ADS8344GB?
A: ADS8344EB: industrial grade -40℃~+85℃; ADS8344GB: commercial grade 0℃~+70℃. Pin‑compatible, cannot cross‑substitute for low‑temperature industrial applications.
Q5: Does ADS8344EB/2K5 include internal voltage reference?
A: No on‑chip reference. External reference (500mV ~ VCC) is required; 2.5V reference is recommended for best accuracy.
Q6: Which models are pin‑to‑pin drop‑in replacements?
A: ADS8344EB (tray) and ADS8344EBG4 (RoHS eco version) are direct drop‑in replacements without hardware or firmware modification. ADS7844 is also pin‑compatible.
Q7: Can ADS8345E/2K5 replace ADS8344EB/2K5 directly?
A: Same SSOP‑20 pinout, but higher sampling rate. Hardware can be mounted directly, yet firmware register settings must be adjusted, not seamless drop‑in swap.
Q8: Difference between SSOP‑20 and QSOP‑20 package?
A: Identical pin assignment and electrical specs. QSOP is shrink thin package; SSOP is standard narrow‑body. PCB footprints are not interchangeable, please match your layout.
Q9: How to get datasheet, CAD model or volume quotation?
A: Submit quick inquiry form for official datasheets, CAD files, stock status and bulk‑order pricing.
