ADS7891IPFBR Description

Short technical summary and product information.

The ADS7891IPFBR is a 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments, offering a sampling rate of 3 MSPS. It includes an internal 2.5V reference and buffer, and features a pseudo-differential input with a 0 V to 2.5 V unipolar range. The device provides a high-speed parallel interface with 8-/14-bit bus transfer capability.

 

Key electrical characteristics include a typical signal-to-noise ratio (SNR) of 78 dB and total harmonic distortion (THD) of -88.5 dB at 3 MSPS. Power dissipation is 85 mW typical at full speed, with a nap mode reducing consumption to 10 mW and a power-down mode drawing only 10 µW. The digital supply voltage range is 2.7 V to 5.25 V, while the analog supply is 5 V.

 

The ADC is designed for applications such as optical networking (DWDM, MEMS switching), spectrum analyzers, high-speed data acquisition systems, telecommunications, and ultrasound detection. It is housed in a 48-pin TQFP (7x7 mm) surface-mount package and operates over a temperature range of -40°C to 85°C.
