ADS7824P

Analog To Digital Converters (ADC) Overview

The ADS7824P is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Burr-Brown. It features an 8-channel multiplexer supporting single-ended or differential input configurations. The device utilizes a serial interface for data output and operates with a maximum conversion time of 6 µs. Key electrical specifications include a maximum linear error of 0.0488%, an integral nonlinearity (INL) of ±1 LSB, and a differential nonlinearity (DNL) of ±1 LSB. It supports a reference voltage range from 100mV to VCC and functions within an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 8-channel analog input multiplexer
• Serial access interface compatible with standard microprocessors
• High linearity: INL and DNL limited to ±1 LSB
• Flexible reference voltage range from 100mV to VCC

Analog To Digital Converters (ADC) Applications

• Test and measurement instruments requiring high-precision signal digitization
• Industrial monitoring systems with multi-channel data acquisition needs
• Scientific research equipment demanding low noise performance

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer origin as Burr-Brown rather than Texas Instruments, noting that Burr-Brown was acquired by TI. Confirm the package type corresponds to the P suffix designation. Ensure compliance requirements are checked against the specific revision, as some sources indicate non-RoHS status for certain variants. Cross-reference datasheet revisions to confirm pinout compatibility.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 12-bit accuracy and 8-channel multiplexing are required in a compact form factor. The serial interface simplifies PCB routing compared to parallel ADCs. Consider the 6 µs conversion speed for applications not requiring ultra-high sampling rates. Verify that the input voltage range aligns with the selected reference voltage configuration.

Analog To Digital Converters (ADC) Part Context

The ADS7824 belongs to the ADS78xx family of precision SAR ADCs. The 'P' suffix typically denotes a plastic small-outline package variant. This model bridges the gap between lower-resolution parallel ADCs and higher-speed serial interfaces, offering a balance of channel count and data throughput for mid-range data acquisition tasks.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7824U is a direct functional substitute with identical electrical characteristics but housed in a SOIC-28 surface-mount package instead of the through-hole or different plastic package associated with the P suffix. Verify pin compatibility before substitution.
