The 4:1 S/H-to-ADC ratio means each input has its own sample-and-hold, so the voltage on all four channels is frozen at the same instant — critical for phase-coherent measurements in multi-phase motor drives or three-phase power monitoring where the timing skew between channels must be below one sample period. ## 680k sps throughput and parallel interface Sampling at 680k samples per second, the ADC delivers one 12-bit result every 1.47 µs. The parallel data interface lets a host controller read the conversion word in a single bus cycle — no serial clock overhead. Reference selection is flexible: use the internal bandgap for a stand-alone design, or drive an external reference when the system already has a precision voltage source. The part is available for new designs and replacement orders alike.","metaTitle":"MAX1305ECM+ 12-bit SAR ADC, 680k sps, 48-LQFP","metaDescription":"MAX1305ECM+ 12-bit SAR ADC, 4-ch single-ended, 680k sps, parallel interface, -40°C to +85°C, 48-LQFP.
