ADS7280IRSAR Description

Short technical summary and product information.

The ADS7280IRSAR from Texas Instruments is a high-performance, 14-bit successive approximation register (SAR) Analog-to-Digital Converter (ADC). It is designed for low-power applications and supports a maximum sampling rate of 1MSPS. The device features a unipolar input range from 0V to VREF and operates with an analog supply voltage ranging from 2.7V to 5.5V.

 

This ADC includes a 2-channel multiplexer and a serial SPI/DSP-compatible interface, supporting SCLK up to 50MHz. It offers excellent DC performance with typical Integral Non-Linearity (INL) and Differential Non-Linearity (DNL) of ±0.4 LSB. AC performance includes an SNR of 85.9dB at 10kHz.

 

The ADS7280IRSAR is available in a 16-QFN (4x4 mm) and a 16-TSSOP package, suitable for surface mounting. It operates across an industrial temperature range of -40°C to +85°C. Comprehensive power-down modes are included to conserve energy during idle periods.

 

Key applications for this ADC include communications, transducer interfaces, medical instruments, magnetometers, industrial process control, data acquisition systems, and automatic test equipment.
