AD7248JNZ Analog Devices

The AD7248JNZ is an 8-bit monolithic delta-sigma analog-to-digital converter (ADC) from Analog Devices. The device is ideal for low-cost microwatt level signal monitoring applications due to its ultra-low power consumption compared to traditional linear-integrating-converting ADCs. It is packaged in a TSSOP-16 surface mount package and operates from an industry standard single supply of 2.7 V to 5.5 V. The device features an integrated sample-and-hold and a low-noise track-and-hold structure ensuring wide dynamic range, low noise, and high linearity. It has a temperature range from -40°C to +125°C and a maximum sampling rate of 1 MSPS. The ADC has a differential input range of -VREF to +VREF and provides an 8-bit output code. The power consumption during conversion is typically 10mW and during standby it is less than 400nW. The AD7248JNZ is ideal for applications such as thermal and pressure sensor measurements, metering applications, consumer electronics, and medical systems.
