ADS7890IPFBT Description

Short technical summary and product information.

The ADS7890IPFBT from Texas Instruments is a high-performance 14-bit, 1.25MSPS Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC). This device is designed for applications requiring precise data conversion with a zero-latency serial interface.

 

Key electrical specifications include a sample rate of 1.25 MSPS and a 14-bit resolution. It offers a pseudo-differential input range of 0 V to 2.5 V and utilizes an SPI compatible serial interface for communication. The ADC includes an internal voltage reference and an internal reference buffer. Power dissipation is typically 45 mW at the maximum sample rate, with options for lower power consumption in nap mode (10 mW) and power-down mode (10 µW).

 

The ADS7890IPFBT is housed in a compact 48-pin TQFP package, suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C, making it suitable for various industrial and telecommunication environments. The pseudo-differential input stage is beneficial for compensating ground voltage mismatches and canceling common-mode noise.

 

Applications for this ADC include high-speed data acquisition systems, optical networking components like DWDM and MEMS-based switching, spectrum analyzers, and high-speed close-loop control systems.
