The AD7190BRUZ is an analog to digital conversion chip manufactured by ADI that offers high accuracy and low noise, making it ideal for high-precision measurement
applications. The AD7190BRUZ is a 24-bit sigma-δ analog-to-digital converter (ADC) with a built-in programmable gain amplifier (PGA) that delivers ultra-low noise
performance. It supports data output rates ranging from 4.7Hz to 4.8kHz and has internal or external clock options. The AD7190BRUZ comes in a 24-pin TSSOP package
and is powered by a 5V analog power supply and a 2.7V to 5.25V digital power supply with a power consumption of 6 mA. The chip operates from -40°C to +105°C and
is suitable for a wide range of industrial and automotive applications.
AD7190BRUZ Features:
- Ultra-low noise performance, root mean square (RMS) noise of 8.5nV (at 4.7Hz, gain G = 128)
- Noise-free resolution up to 22.5 bits (at gain G = 1)
- Offset drift is 5 nV/ C and gain drift is 1 ppm/ C
- Stable time drift characteristics
- Supports 2 differential or 4 pseudo-differential input channels
- Certified for automotive applications
- Two digital filter options are available that affect noise performance and output data rate
- Zero latency for applications that require all conversions to be established
- Support 3-wire SPI, QSPI™, MICROWIRE™ and DSP-compatible serial interfaces
