AD7193BCPZ

AD7193BCPZ is the Analog Devices AD7193 24-bit sigma-delta ADC in a 32-lead LFCSP — electrically identical to the TSSOP-28 AD7193BRUZ, repackaged for space-constrained, high-density boards: four fully differential or eight pseudo-differential inputs, PGA gains of 1 to 128, output data rates from 4.7 Hz to 4.8 kHz, and 11 nV RMS noise at 4.7 Hz with gain 128 (15.5 noise-free bits at 2.4 kHz, up to 22 at gain 1). The LFCSP footprint suits automated assembly and compact transmitter or data-acquisition modules where the leaded TSSOP will not fit, while the shared die and register model let firmware carry over unchanged between package variants. Analog Devices lists the AD7193 in production; supply is AVDD 3 V to 5.25 V and DVDD 2.7 V to 5.25 V at 4.65 mA, specified from -40 to +105 °C. Selection advice: choose BCPZ for the LFCSP-32 footprint; choose AD7193BRUZ when a leaded TSSOP-28 is preferred for prototyping or rework; match the full code because the package is the difference.
