Description
The AD7790BRMZ is a low-power, 16-bit sigma-delta (Σ-Δ) ADC from Analog Devices, designed for precision measurement applications. It features an on-chip instrumentation amplifier, making it ideal for low-frequency signals like those from strain gauges, thermocouples, or RTDs.
Key specifications:
- Resolution: 16 bits
- Channels: 1 differential or 2 pseudo-differential
- Output Data Rate: 4.17 Hz to 470 Hz (adjustable)
- Interface: SPI-compatible
- Supply Voltage: 2.7V to 5.25V
- Low Power: 65 µA (typical)
The AD7790BRMZ includes internal clocking, reducing external component needs, and offers low noise (1.1 µV RMS) for high-accuracy sensing. It comes in a compact MSOP-10 package, suitable for space-constrained designs.
Common applications include industrial process control, medical instrumentation, and portable sensing devices. Its integrated features simplify signal conditioning, making it a cost-effective choice for precision analog front-ends.
