ADS7825PB

Analog To Digital Converters (ADC) Overview

The ADS7825PB is a 4-channel, 16-bit sampling CMOS analog-to-digital converter (ADC) manufactured by Burr-Brown. It features a successive approximation register (SAR) architecture with a maximum sampling rate of 40 kS/s. The device operates on a single 5V supply, accepting analog input voltages from -10.0 V to +10.0 V. Key electrical specifications include an SNR of 83 dB, DNL of +/- 1 LSB, and INL of +/- 3 LSB. Power consumption is limited to 50 mW. Data output is configurable via parallel or serial interfaces controlled by the PAR/SER pin.

Analog To Digital Converters (ADC) Feature Summary

• Four analog input channels with internal multiplexer supporting -10.0 V to +10.0 V range
• Configurable data output interface allowing selection between parallel and serial modes
• Low power consumption of 50 mW with single 5V supply operation
• Integrated over-voltage protection on analog inputs

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution multi-channel acquisition
• Data acquisition systems for precision measurement applications
• Instrumentation equipment utilizing microprocessor interfaces

Analog To Digital Converters (ADC) Part Context

The ADS7825PB belongs to the ADS7825 family of ADCs. The 'PB' suffix indicates a plastic DIP package variant, distinguishing it from surface-mount options like the SOIC-28 package used in the ADS7825U. This component integrates a 16-bit DAC, clock, reference voltage, and control logic within a single chip.

Analog To Digital Converters (ADC) Replacement Considerations

Compatible alternatives within the same family include the ADS7825P and ADS7825PB. Designers must verify package compatibility when substituting surface-mount variants like ADS7825U for through-hole versions.
