AD7873BCPZ

Overview

The AD7873BCPZ is a 12-bit successive approximation analog-to-digital converter (ADC) designed for resistive touch screen digitizer applications. It integrates low on-resistance switches, an internal 2.5 V reference, and a temperature sensor. Operating from a single 2.2 V to 5.25 V supply, it achieves throughput rates up to 125 kSPS with a synchronous serial interface. The device supports programmable 8-bit or 12-bit resolution and includes shutdown mode reducing current consumption to less than 1 µA.

Feature Summary

12-bit resolution with 125 kSPS throughput rate
Integrated 4-wire touch screen interface with low on-resistance switches
On-chip 2.5 V reference and temperature sensor (-40°C to +85°C)
Single supply operation (2.2 V to 5.25 V) with <1 µA shutdown current

Applications

Personal digital assistants
Smart hand-held devices
Touch screen monitors
Point-of-sale terminals
Pagers

Procurement Notes

Verify the specific suffix CPZ indicates the Lead Frame Chip Scale Package (LFCSP) variant. Confirm availability status as distribution channels may list this component as discontinued or limited stock depending on the region. Ensure compatibility with EVAL-AD7873EBZ development kits if prototyping.

Selection Notes

Select the AD7873BCPZ for battery-powered systems requiring space-saving LFCSP packaging. Choose this model over QSOP/TSSOP variants when board real estate is constrained. Verify that the 12-bit resolution and 125 kSPS speed meet system latency requirements for resistive touch interfaces.

Part Context

The AD7873BCPZ belongs to the Analog Devices AD7873 family of touch screen controllers. It shares core specifications with the AD7873BRQZ and AD7873ARUZ but differs in package type. The BC designation typically denotes industrial temperature range performance within the series.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider evaluating other members of the AD7873 family such as the AD7873ARUZ or AD7873BRQZ for pin-compatible alternatives in different packages.
