ADS7883SDBVR

The ADS7883SDBVR is a 12-bit successive approximation register (SAR) analog-to-digital converter from Texas Instruments. It achieves a maximum sample rate of 3 MSPS (3 million samples per second) via a 48-MHz SPI serial interface. The device operates from a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. Typical power consumption is 13.5 mW at 5 V, 3 MSPS, and 6.45 mW at 3 V, 2 MSPS. The ADC offers a unipolar input range of 0 V to VDD and includes a sample-and-hold circuit with a 1:1 ratio.

Performance specifications include ±0.6 LSB integral nonlinearity (INL), ±0.5 LSB differential nonlinearity (DNL), 72 dB SINAD, and -84 dB THD. The device features zero latency, enabling immediate conversion results. The input bandwidth is 30 MHz at 3 dB. The ADS7883SDBVR is housed in a space-saving 6-pin SOT-23 (SOT-23-6) package and supports surface-mount mounting for automated assembly. It is rated for the industrial temperature range of -40°C to 125°C.

Typical applications include base band converters in radio communication, motor current and bus voltage sensors in digital drives, optical networking (DWDM, MEMS-based switching), optical sensors, battery-powered systems, medical instrumentation, high-speed data acquisition systems, and high-speed closed-loop systems.
