AD4430-1YKSZ-R7 – ANALOG DEVICES

The Analog Devices AD4430-1YKSZ-R7 is a low-power, high-accuracy, single-channel, 24-bit Σ-Δ ADC with an integrated reference. Specifically, the “-R7” suffix denotes a factory-trimmed version guaranteeing superior accuracy. This device operates from a 2.7V to 5.5V supply voltage, making it suitable for a wide range of battery-powered applications. Its key specifications include a maximum input range of 0V to VREF (typically 2.5V), a throughput rate of 100kSPS, and a total unadjusted error of less than ±1 LSB. Packaged in a space-saving 10-lead LFCSP (lead-frame chip scale package), it minimizes board space._x000D_
