The AD7873BRQZ is a 12-bit successive approximation ADC with a synchronous serial interface, designed for touch screen digitizer applications. It operates from a single 2.2V to 5.25V supply and achieves a throughput rate of 125 kSPS. The device includes a 4-wire resistive touch screen interface, an on-chip temperature sensor covering -40°C to +85°C, and an on-chip 2.5V reference. Additionally, it supports direct battery measurement from 0V to 6V and touch pressure measurement. The AD7873BRQZ is available in a 16-lead SSOP (QSOP) package for surface mount assembly. It offers a shutdown mode with maximum current of 1 µA, making it suitable for power-sensitive portable devices. The serial interface allows easy connection to microcontrollers. The device is specified for the industrial temperature range of -40°C to +85°C.
The supply voltage range is 2.2V to 5.25V.
The operating temperature range is -40°C to 85°C.
The AD7873BRQZ has 12-bit resolution and a sampling rate of 125 kSPS.
It supports a 4-wire resistive touch screen interface.
The package is 16-SSOP (0.154", 3.90mm Width) which corresponds to the supplier package 16-QSOP.
The product is listed as RoHS3 Compliant, but this status is unverified.
Yes, it has an on-chip 2.5V reference that can be used for auxiliary input, battery monitor, and temperature measurement. An external reference can also be applied.
