Description
The AD7794BRUZ-REEL is a low-power, 24-bit sigma-delta (Σ-Δ) ADC from Analog Devices, designed for precision measurement applications. It features 3 differential/6 pseudo-differential input channels, an on-chip low-noise PGA (programmable gain amplifier), and an internal reference voltage.
Key specifications:
- Resolution: 24 bits (no missing codes).
- Output data rate: 4.17 Hz to 470 Hz (adjustable).
- Power supply: 2.7V to 5.25V, consuming <500 µA (typical).
- Interface: SPI-compatible.
- Package: 24-lead TSSOP (BRUZ), tape-and-reel (REEL).
Ideal for industrial sensors, weigh scales, and medical instruments, the AD7794 offers high accuracy with low noise (40 nV RMS at 4.17 Hz). Its integrated features reduce external component needs, simplifying design.
