ADS7883SDBVT

The ADS7883SDBVT from Texas Instruments is a miniature, micropower, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC). It offers a high sample rate of up to 3 MSPS with zero latency, making it suitable for high-speed data acquisition systems. The device features a wide supply voltage range of 2.7V to 5.5V and low power dissipation, with typical consumption of 6.45 mW at 3V and 2 MSPS, and 13.5 mW at 5V and 3 MSPS.

Key electrical characteristics include ±0.6 LSB INL and ±0.5 LSB DNL, a SINAD of 72 dB, and THD of -84 dB. The unipolar input range is from 0V to VDD, with a wide input bandwidth of 30 MHz at 3 dB. The serial interface supports SPI communication, allowing for glueless connections with microprocessors and DSPs.

This ADC is available in a compact 6-pin SOT-23 package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C. The device also includes a power-down feature for reduced consumption when operated at lower conversion speeds.

Applications for the ADS7883SDBVT include base band converters in radio communication, motor current/bus voltage sensors in digital drives, optical networking, optical sensors, battery-powered systems, medical instrumentation, and high-speed closed-loop systems.
