Texas Instruments ADS7881 2.7V-5.25V Digital, 5V Analog, 12 Bit, 4MSPS, Parallel ADC with Ref ADS7881IPFBR

The ADS7881IPFBR is a 12-bit, 4 MSPS analog-to-digital converter (ADC) designed for applications requiring high-speed data acquisition. It operates with a digital supply voltage range of 2.7V to 5.25V and an analog supply voltage of 5V. The device features a unipolar, pseudo-differential input range of 0V to 2.5V and includes an internal reference voltage of 2.5V along with a reference buffer. This ADC provides a high-speed parallel interface, making it suitable for integration with various digital systems, including 8-bit processors through its byte mode. The device boasts a signal-to-noise ratio (SNR) of 71 dB and total harmonic distortion (THD) of -88.5 dB at 1 MHz input frequency, indicating strong performance in dynamic applications. Power dissipation is rated at 95 mW during operation at 4 MSPS, with a nap mode that reduces power consumption to 10 mW and a power-down mode that further lowers it to 10 µW. The ADS7881IPFBR is available in a 48-pin TQFP package and operates over a temperature range of -40°C to 85°C, making it suitable for a variety of industrial and telecommunications applications, including optical networking and high-speed data acquisition systems.
