ADS7280IRSAT

Analog To Digital Converters (ADC) Overview

The ADS7280IRSAT is a dual-channel, simultaneous-sampling analog-to-digital converter manufactured by Texas Instruments. It features a 12-bit resolution and operates at a sampling rate of 750 kSPS per channel. The device utilizes a Successive Approximation Register (SAR) architecture and accepts pseudo-differential or single-ended inputs. It supports an analog supply voltage range of 4.5V to 5.5V and a digital supply voltage range of 1.65V to 5.5V. Data transfer is handled via a standard SPI interface compatible with DSP systems. The component is housed in a 16-pin VQFN package with exposed pad, rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling capability across two independent channels ensures precise phase alignment for differential signal processing applications.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-speed data acquisition
• Medical ultrasound imaging equipment
• Acoustic emission monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRSAT' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure that the external reference voltage source meets the noise and stability specifications outlined in the official documentation to maintain optimal ADC performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is required rather than multiplexed conversion. Verify that the system clock frequency aligns with the maximum SCLK limits defined in the datasheet. Confirm that the input signal amplitude remains within the specified common-mode and differential voltage ranges for the selected supply voltage.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS72xx family of high-speed, low-power SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS7230 but provides simultaneous sampling instead of multiplexed inputs. The 'IR' designation indicates the industrial temperature range, while 'SAT' specifies the tape and reel packaging format.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7230IRSAR is listed as a parameter-equivalent alternative. However, it offers multiplexed inputs rather than simultaneous sampling. Verify if the application requires true simultaneous conversion before substituting.
