ADS7841PB

Analog To Digital Converters (ADC) Overview

The ADS7841PB is a 12-bit, four-channel serial output sampling analog-to-digital converter (ADC) manufactured by Burr-Brown. It utilizes a successive approximation register (SAR) architecture to achieve a maximum sampling rate of 200 kS/s. The device supports both differential and single-ended input configurations, offering flexibility in signal acquisition. It operates on a single power supply ranging from 2.7 V to 5.25 V for both analog and digital domains. Key performance metrics include a signal-to-noise-and-distortion ratio (SINAD) of 72 dB, with integral nonlinearity (INL) and differential nonlinearity (DNL) specified at ±2 LSB and ±0.8 LSB, respectively. The component is housed in a plastic dual in-line package.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with four multiplexed analog input channels
• Serial interface compatible with standard SPI protocols
• Low power consumption of 1.8 mW at full speed
• Wide single-supply operation from 2.7 V to 5.25 V

Analog To Digital Converters (ADC) Applications

• Portable instrumentation and data acquisition systems
• Industrial process control monitoring
• Battery-powered measurement devices

Analog To Digital Converters (ADC) Part Context

The ADS7841PB belongs to the ADS7841 series of high-speed, low-power ADCs produced by Burr-Brown, which was acquired by Texas Instruments. This specific part number denotes the plastic DIP variant of the 12-bit, 4-channel converter. The series is designed for applications requiring moderate speed and high accuracy in a compact form factor, bridging the gap between lower-resolution parallel ADCs and higher-speed serial alternatives.

Analog To Digital Converters (ADC) Replacement Considerations

For direct pin-compatible replacements within the same family, consider the ADS7844, which offers eight channels instead of four while maintaining similar electrical characteristics and interface requirements.
