AD7194BCPZ Chip Overview Analog to Digital Converter
The AD7194BCPZ is a high-precision, low-noise analog front-end device featuring a 24-bit Sigma-Delta analog-to-digital converter (ADC) with a programmable gain amplifier (PGA). It is designed for demanding measurement applications requiring ultra-low noise and high resolution. The device supports eight differential or sixteen pseudo-differential input channels and offers a maximum sampling rate of 4.8 kHz. It is housed in a 32-lead LFCSP package and operates over an extended temperature range from -40°C to +105°C.
AD7194BCPZ Features
The AD7194BCPZ offers several key features that make it suitable for high-precision applications. It includes a low-noise, 24-bit Sigma-Delta ADC with a programmable gain range from 1 to 128, allowing direct interfacing with small signal sensors. The device provides an RMS noise level of 11 nV at 4.7 Hz with a gain of 128 and achieves up to 22 noise-free bits at gain = 1. It also supports internal or external clocking, simultaneous 50 Hz/60 Hz rejection, and four general-purpose digital outputs. The device is powered by a supply voltage range of 3 V to 5.25 V for the analog section and 2.7 V to 5.25 V for the digital section.
