AD7194BCPZ

AD7194BCPZ is an Analog Devices 24-bit sigma-delta ADC in a 32-lead LFCSP, the high-channel-count member of the AD719x family: eight fully differential or sixteen pseudo-differential inputs double the AD7193 channel count for multi-sensor data acquisition, batch weighing and process monitoring on a single converter. The signal chain matches the family's precision class — PGA gains of 1 to 128, output data rates from 4.7 Hz to 4.8 kHz, 11 nV RMS noise at 4.7 Hz with gain 128, 15.5 noise-free bits at 2.4 kHz and up to 22 noise-free bits at gain 1 — so channel count scales without giving up the low-noise front end that load cells and RTDs need. It operates from AVDD of 3 V to 5.25 V and DVDD of 2.7 V to 5.25 V at 4.65 mA, specified from -40 to +105 °C. Selection advice: the AD7194 comes only in LFCSP-32 — choose it when eight differential channels are genuinely required; for four channels the AD7193 on this site offers TSSOP-28 and LFCSP-32 options; confirm channel count and package in your RFQ so the offered lot matches the layout.
